Nice idea for a rather underserved space. Another start-up in the sector is StrongArm (www.strongarm.com) a NYC based company that tries to inovate in the space of weight lifting devices.

These designs seem to be missing a big factor which is the cost and effort necessary to build one of these shoulder poles. They're targeting the extremely poor demographic and any design that requires complicated construction would be impossible to build.
- txu 12y ago
  It's also my question. A working design must also be cheap. The "A liter of light" project is a great example. https://www.youtube.com/watch?v=o-Fpsw_yYPg https://www.youtube.com/watch?v=o-Fpsw_yYPg The prototypes shown are far from achieving cost effectiveness it seems.

  Carving some curved wood to enlarge the contact area doesn't seem like it would be that hard or expensive. Or even a bit of leather, cloth or rope. So they've been using this pole for 1,000 years. Yet I see it for 1 minute and I want to improve it. Why? What makes me different from them? Why did they not try to improve it themself? What am I missing?
  - jrochkind1 12y ago
    I think there are two possible answers. A) There is a hidden advantage of some sort to the current design that the designers in OP are not aware of or not taking account of. It could just be cost as another poster suggested, or something else. B) No good reason at all, just tradition. I can't find it now, but there was a post on HN asking why we still used the traditional Western wheelbarrow in our countries, when the Chinese wheelbarrow (what a coincidence!) was so obviously superior. The Chinese wheelbarrow has the wheel in the middle, so the wheel bares the load and the human just needs to push/steer.
    - jrochkind1 12y ago
      Heck, maybe nobody in China ever bothered to improve the shoulder pole, because they didn't need to when they had the superior Chinese wheelbarrow!

    > So they've been using this pole for 1,000 years. > What makes me different from them? You probably don't have the experience of use that comes with 1000 years. Or even one summer. As I see it, the tool is already adequate. Especially in bamboo form, the pole has some flex and a smooth surface. Adding curved wood or fabric would cause additional rubbing wear. In the case of curved wood (and some of the prototypes), you lose versatility in how you can use it. When these guys go up and down narrow stairs, they follow each other closely, each leading with one basket higher and in front. The designs that lock into the torso would make navigating steps and quick direction changes harder.
  - dengnan 12y ago
    For cost consideration? Those poles are made of bamboos which is probably the most inexpensive materials in ancient China and it's easy to get. The shape of the poles is exactly the same as the raw materials. So people only need to cut the bamboo and that's it. No need to do any further work. Bamboos grow very fast and straight. This makes it have very low defective rate. Imagine there was no plastic, no composite wood. You had to find a large piece of wood to do even a small design. Plus, if there was really a needs for alternatives, there was Chinese weelbarrow [0]. http://www.lowtechmagazine.com/2011/12/the-chinese-wheelbarrow.html http://www.lowtechmagazine.com/2011/12/the-chinese-wheelbarr...
- contingencies 12y ago
  Yes. In fact, there are a number of advantages offered by the current design that have not been discussed. As I live in the area and have lots of experience seeing people use these in Southeast Asia and southern China (where I usually live), here's some off the top of my head: 1. Quick to make from local, natural, sustainable, free materials. You just split half a piece of bamboo (fast growing, flexible, everywhere in southern China/South/Southeast Asia). Can be replaced almost in-situ if broken, stolen, destroyed by local police/mafia, etc. 2. Easy to balance. The most traditional use of these sorts of poles is for bringing large loads of produce through paddy fields. In order to do so, one must frequently balance on thin muddy paths and cross streams. This is in addition to the steep and rocky terrains mentioned. 3. Easy to unload (drop the pole), without losing or upsetting your load. Thus, deniable in places where traditional street vendors are currently being pushed out by local police. (See also #1) 4. Cool and stays out of the way. Does not impede airflow to body or movement of head which may need to wear a large-brim hat. Critically important in hot and/or wet terrain, and steep terrain. 5. Can spin on the shoulder. Forward-backward orientation for thin paths (through people, planted or natural vegetation, traffic, thick foliage, rocks) or left-right orientation for lower shoulder load where feasible. 6. Skilled operators can rapidly and easily switch supporting position from the left to right shoulder very easily even under heavy load. This facilitates rest for part of the shoulder which largely offsets the alleged discomfort under high load and prolonged use. 7. To place or pick up light to medium loads (eg. mobile food preparation equipment that may include hot coals, boiling water, or similar ... relatively commonly seen in parts of Vietnam), it is sometimes useful to bend rather than fix your back in order to ensure a shock-free placement, at which point the proposed body-mounted supports become restraining. I would also point out backpacks or harnesses of the type proposed do already exist but are usually used in different situations, ie. to carry heavier loads closer to the back up mountainous terrain where balance and wide, vegetation/rock-free paths cannot be guaranteed.

What are the thoughts behind redesigning the pole itself, rather than designing a shoulder pad/attachment to better distribute the weight? It seems like an attachment would be better able to be reused with the poles they currently have, cheaper to create/transport, and allow for better one-shoulder usage. A huge advantage of shoulder poles is that they can be carryed across one shoulder through narrower corridors, and only the second prototype seems to account for this. The first prototype does showan example of one-shoulder use, but it's clearly not meant for it (and looks a little bit like football shoulder pads worn the wrong way)
protomyth 12y ago
First, great idea and design. I don't normally comment on sites layouts, but this one has some massive jpegs instead of text and smaller pictures. I am not sure what they are trying to gain. It actually looks like they don't have the text at all.
- teleclimber 12y ago
  Yeah at first I thought "hey somebody actually took the time too code an elaborate HTML page." Then I realized it's all images. The truth is creating a page like that in HTML is totally possible, but it's a very labor-intensive and technical process. That's too bad.

titanomachy 12y ago
> ... which means that 4.7 billion people in China have only less than 2 dollars per day to subsist. Um. Did somebody misplace a decimal point?
- solox3 12y ago
  Yeah, the Chinese have a unit of measurement called "yi" which is exactly 0.1 billion.
- b6 12y ago
  To expand on what solox3 said, Chinese people put commas in numbers after every 4 digits instead of every 3. I find it kind of confusing when I need to say 3 ten-thousands, instead of 30 thousands. It looks like that kind of mistake to me.
  - protomyth 12y ago
    I thought 4 was not a good number, why after every 4?
    - b6 12y ago
      It's true, they tend to avoid it because 四 (si4, "four") sounds similar to 死 (si3, "die"). I don't know why they settled on that way. It seems pretty arbitrary, though. I'd like to find out more.
    - jcampbell1 12y ago
      Chinese has single words for 100, 1000, 10000, 100000000. In english we have single words for, 100, 1000, 1000000, 1000000000. Indians have a word for 1000000. The commas just serve to make a numbers more readable, thus in chinese there are 4 digits between the commas. It is hard to argue that one system is better than another, but English has the nice property that 2^10 ~= thousand, 2^20 ~= million, 2^30 ~= billion, 2^40 ~= trillion. So i'd argue that English is superior in this respect. Chinese Big-to-Small for dates and many other things is vastly superior to English. Chinese date format is 2015-02-15, and address format is Country, Region, City,Street, number.
sqrt17 12y ago
Germany in the 1700s/1800s had similar shoulder poles for carrying water: http://static3.akpool.de/images/cards/65/655879.jpg http://static3.akpool.de/images/cards/65/655879.jpg They added a thicker, slightly regressed bit in the middle to avoid the some of the pressure on the shoulder/neck area.
- pnathan 12y ago
  If I understand wood well enough, that particular pole would have been carved out of a plank though, yea?
mmilano 12y ago
Would the fixed fulcrum handle un-even loads the same way? I understand you can distribute weight on each side but seems like it would be more difficult to load vs a non-fixed fulcrum.
- westiseast 12y ago
  I think the user typically balances uneven loads with their hand slung over one side (ie, carrying the pole front-to-back rather than side-to-side). In this way the flexibility of the original design is useful.
- ChuckFrank 12y ago
  You are correct. Fixed fulcrum, not a good idea. Non-fixed fulcrum, a great idea. The existing design is better on this case.
simonsayscode 12y ago
I don't think that this is meant to be sold to the poor demographic. I would rather think that this is just applying design principles and the design sprint as an exercise to an untouched piece of technology. That being said, I could easily imagine some charity that either sells these designs at an extremely (or free) discounted rate to these workers in an effort to relieve back pain and the myriad of other physiological issues the traditional pole yields.
- bullfightonmars 12y ago
  Exactly! This is an exercise in design research. Well composed, well documented, and well presented. The point of this isn't necessarily to solve pole design it is to explore designing for a specific problem generatively with some domain experts. This kind of practice can be applied to any given domain or problem and is extremely effective at bringing a team together to build an unify product vision.

They should look at what people squat with. Consider this piece of plastic: http://www.bodybuilding.com/fun/betteru50.htm http://www.bodybuilding.com/fun/betteru50.htm
- darkmighty 12y ago
  Yea I think the key here would be looking at technologies both extremely cheap and currently unavailable to villagers (otherwise they would probably have thought of it). Mass produced plastic support seems to fill that role. You could even join a shoulder rest part to allow switching orientation!
jdonaldson 12y ago
There's more efficient ways of carrying heavy loads, but the shoulder pole is remarkably efficient in a number of other ways. Its most important feature is that you're able to pivot the pole about the body, bringing the pole in front of you, and letting you fit into tighter spaces. Or, you can pivot the other direction, and spread more load across your shoulders. By spreading the weight apart, you're able to keep your balance extremely well. Since they're focused on avoiding strain, they should be looking at ways of distributing more of the load across the lower torso and hips. One of their mockups looks like they're trying to do this, but the result looks like you give up a lot of flexibility.
- ChuckFrank 12y ago
  Yes, the pivot as well.
dylanbox 12y ago
I always have a problem with social design challenges like this. Outsiders always have some notion that they're more capable of coming up with solutions for these "problems" than the people who actively live with them. It typically ends up being over-engineered or flawed due to ignoring some cultural reasons for the status quo. Working as a designer at social enterprise dedicated to water purification in India clued me into one particular case of this over engineering. A well-known design firm did a month-long visit at my company to design a new carrying method for the water cans that people used to transport filtered water back to their homes or businesses. They did many of these same "studies" and prototypes and came up with this plastic clip to hook a 20 liter jerry can to the side of a bike or motorcycle. They distributed them to customers, took some pictures and left. Within a month most were lost, broken, or found too difficult to use. In the end what was the solution that people ended up using? A simple piece of sheet metal bent into an s-curve and hooked over the sides of the bike frame. Cheap, simple, and easy to manufacture. It was designed and made by a customer of the company, by himself. You don't need a college education and a design background to come up with the correct solution; most people know what they need, and they will go out and make it happen. These shoulder poles are a perfect example of Jugaad solutions, an innovative fix or work-around. It might just not be as sexy as one you'll find in a design studio or classroom. This op-ed from NY Times about a $300 house design contest from a few years back does a similar job articulating the point, too. It's worth a read: http://www.nytimes.com/2011/06/01/opinion/01srivastava.html http://www.nytimes.com/2011/06/01/opinion/01srivastava.html

  Sounds like the designers that decided that on a tv remote the clip that holds the battery door in place needs to be the flimsiest thinnest piece of plastic imagineable.

You could modify a Manta Ray[0] to accommodate the over-one-shoulder position. But it seems like to problem isn't well defined. There are a lot of problems that shoulder poles solve. "Moving stuff cheaply under human power" captures a lot of it, but I think that the designers might have defined them selves in to a corner by saying that they want to make a monotonically superior tool. Pick one problem and solve just that one problem in a better way. Maybe that's the lesson though. The shoulder pole is a really awesome piece of tech.

hyperion2010 12y ago
As said by many others: they really aren't taking cost into account. The cost free solution already exists in many domains, the one I'm most familiar with is canoe thwarts: http://www.noahsmarine.com/ucimages/yokes-lg.jpg http://www.noahsmarine.com/ucimages/yokes-lg.jpg. Figure out how to print something with this shape out of plastic and... well you have a hundred million pieces of plastic that you need to do something with now.
ChuckFrank 12y ago
This is terrible. The pole needs to be able to move back and forth to accommodate different fulcrum points with relationship to differing weights. See video at 1:20 mark. https://www.youtube.com/watch?v=WWAO3ZhD8_Q https://www.youtube.com/watch?v=WWAO3ZhD8_Q Plus, the flat dual pole method allows for some spring in the pole so that it doesn't weigh down the carrier with each step. I'm glad that this was posted by OP. We need to be able to discuss design failures like this, instead of just down voting them. I think all this could have been avoided if the design firm had been forced to use a pole for all their carrying needs for a week, or even a month, out in the field. The first two things that they would have discovered is the beauty of moving the fulcrum point and the fact that it's nice for a pole to have some bounce to it. Additionally, the pictures of them trying on the poles, in their corporate meeting rooms, gave me the absolute creeps, smacking of entitled ignorance, to both the problem and the solution. God I hope we aren't backlashing and heading back to an age of internationalism with regards to design, just because we became such relativists in post modernism that we thought that no single solution could be better than another. Arrgh.
- ChuckFrank 12y ago
  jdonaldson mentions the pivot as well. Yes, the current pole allows the user to pivot to be parallel and perpendicular to their pole.
  - ChuckFrank 12y ago
    mmilano mentions benefits of non-fixed fulcrum as well.

They did many of these same "studies" and prototypes and came up with this plastic clip to hook a 20 liter jerry can to the side of a bike or motorcycle. They distributed them to customers, took some pictures and left. Within a month most were lost, broken, or found too difficult to use. In the end what was the solution that people ended up using? A simple piece of sheet metal bent into an s-curve and hooked over the sides of the bike frame. Cheap, simple, and easy to manufacture. It was designed and made by a customer of the company, by himself. You don't need a college education and a design background to come up with the correct solution; most people know what they need, and they will go out and make it happen. These shoulder poles are a perfect example of Jugaad solutions, an innovative fix or work-around. It might just not be as sexy as one you'll find in a design studio or classroom. This op-ed from NY Times about a $300 house design contest from a few years back does a similar job articulating the point, too. It's worth a read: http://www.nytimes.com/2011/06/01/opinion/01srivastava.html http://www.nytimes.com/2011/06/01/opinion/01srivastava.html

Sounds like the designers that decided that on a tv remote the clip that holds the battery door in place needs to be the flimsiest thinnest piece of plastic imagineable.

  This[1] is the best battery door design I've seen on a tv remote. [1] http://www.youtube.com/watch?v=RwGvuQFaDE4 http://www.youtube.com/watch?v=RwGvuQFaDE4

You could modify a Manta Ray[0] to accommodate the over-one-shoulder position. But it seems like to problem isn't well defined. There are a lot of problems that shoulder poles solve. "Moving stuff cheaply under human power" captures a lot of it, but I think that the designers might have defined them selves in to a corner by saying that they want to make a monotonically superior tool. Pick one problem and solve just that one problem in a better way. Maybe that's the lesson though. The shoulder pole is a really awesome piece of tech.

As said by many others: they really aren't taking cost into account. The cost free solution already exists in many domains, the one I'm most familiar with is canoe thwarts: http://www.noahsmarine.com/ucimages/yokes-lg.jpg http://www.noahsmarine.com/ucimages/yokes-lg.jpg. Figure out how to print something with this shape out of plastic and... well you have a hundred million pieces of plastic that you need to do something with now.

This is terrible. The pole needs to be able to move back and forth to accommodate different fulcrum points with relationship to differing weights. See video at 1:20 mark. https://www.youtube.com/watch?v=WWAO3ZhD8_Q https://www.youtube.com/watch?v=WWAO3ZhD8_Q Plus, the flat dual pole method allows for some spring in the pole so that it doesn't weigh down the carrier with each step. I'm glad that this was posted by OP. We need to be able to discuss design failures like this, instead of just down voting them. I think all this could have been avoided if the design firm had been forced to use a pole for all their carrying needs for a week, or even a month, out in the field. The first two things that they would have discovered is the beauty of moving the fulcrum point and the fact that it's nice for a pole to have some bounce to it. Additionally, the pictures of them trying on the poles, in their corporate meeting rooms, gave me the absolute creeps, smacking of entitled ignorance, to both the problem and the solution. God I hope we aren't backlashing and heading back to an age of internationalism with regards to design, just because we became such relativists in post modernism that we thought that no single solution could be better than another. Arrgh.

jdonaldson mentions the pivot as well. Yes, the current pole allows the user to pivot to be parallel and perpendicular to their pole.

  mmilano mentions benefits of non-fixed fulcrum as well.
