Self Sanitizing Door Handle
- ndegruchy 9mo agoAn interesting take. There is also brass and coppers that self-sanitize, albeit more slowly: https://pmc.ncbi.nlm.nih.gov/articles/PMC11279221/ https://pmc.ncbi.nlm.nih.gov/articles/PMC11279221/
- fainpul 9mo agoAnd for metal surfaces which are not self-sanitizing by nature, like steel, there are coatings which can be applied to achieve the same effect. This is often used in public transport.
- indolering 9mo agoCitation? Microban et al are marketing bunk.
- NetMageSCW 9mo agoMicroban is a company, not a product, and they make a wide range of products, some of which are zinc or silver based coatings and effective in slowing the growth of bacteria and fungus.
- mahrain 9mo agoThe TiO2 will likely rub off and need regular replenishment. Also, the alternative here, sensor-operated or button-operated automatic doors are already widely used. I wonder who this is meant for?
- vimda 9mo agoThis is probably easier to install or retrofit than an automatic door, seeing as it self powers
- interludead 9mo agoMotion sensors and push plates aren't perfect, but they remove the contact vector entirely instead of trying to mitigate it after the fact
- RamblingCTO 9mo agoSounds like a problem not worth solving? In my wework the handles get wiped down as per the cleanign protocol. Takes what, a second? The costs are marginal.
- vimda 9mo agoI suppose a second every few hours over dozens of doors adds up. And this has the benefit of being continual, so you don't get build up between cleans. I'm sceptical myself that the tiny generator they have could produce enough energy, and that the coating they have won't be more of a hassle, but the idea is reasonable
- therein 9mo agoHow about silver plating?

- colordrops 9mo agoWhat about bathroom doors that are touched constantly?

- logicallee 9mo agoWhat makes you think so? One of the section titles says "Your inspiration" (rather than "Our inspiration"), which sounds like ChatGPT was writing to them. That wasn't around in 2019.
- sigio 9mo agosee the url, dysonaward ... so probably the site/judges asking/interviewing the inventor of this product.

- billynomates 9mo agoI doubt they used ChatGPT, considering the spelling mistakes
- 4gotunameagain 9mo agoOr, you know, just use brass: https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_touch_surfaces https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_tou...
- BitsAndObjects 9mo agoCame here to find/post this comment :D
- voidUpdate 9mo agoMe too lol
- 3D30497420 9mo agoNot sure how quickly the one from the post takes, but according to the Wikipedia article, brass disinfects "within two hours or less". I could see plenty of transmission within one to two hours. Perhaps it is a difference of speed?
- actionfromafar 9mo agoStill, all regular handles, at least in hospitals, should be uncoated brass. Whenever I see chromed plated handles, slightly worn, exposing the brass below, I think "such a missed opportunity". It shouldn't have been plated to begin with.
- immibis 9mo agoClicked away after 3 popups
- nilslindemann 9mo agoI guess my "I still don't care about cookies" add-on prevents the pop-ups, but one of the other add-ons prevents the video from playing. Or the site is just broken.
- GrowingSideways 9mo agoWhy not just use brass? Seems like a solution in search of a problem.
- interludead 9mo agoThis feels like a thoughtful engineering project and a strong competition entry yet without a clear niche
- kaffekaka 9mo agoI thought it would be about that red hot door handle from Home Alone.
- h1fra 9mo agoOr use copper
- madmaniak 9mo agoHundreds year old technology used in houses, hospitals and public places - handles made of bronze.
- ChoGGi 9mo agoWhy not a door you can push open both ways?
- simojo 9mo agoYou have to let the engineers over-engineer. It's a healthy release.
- cainxinth 9mo agoCool idea and cool looking, but just want to point out that surface transmission of infections is several orders of magnitude less common than airborne transmission.
- mhb 9mo agoAnd easily thwarted by washing your hands.
- rendaw 9mo agoAnd then grabbing the bathroom door handle.
- mandeepj 9mo agoGrab bathroom door handle with a napkin then or use a pocket hand sanitizer
- ssl-3 9mo agoWith my sleeve. (Although I did see a lot of foot-operated door handles emerge on public restroom doors during the covid years. They're mounted down low, near the floor, and you can just put your shoe on them and drag the door open without using hands. They make sense to me for what I think are a lot of good reasons.)
- vee-kay 9mo agoThe Metro (trains) stations in my city have foot-operated levers (pedals) to control the elevators/lifts, doors, toilet taps/faucets (though the urinal themselves have sensors to auto-flush), etc. Although, as a precaution, I carry a hand-sanitizer and fresh mask in my bag whenever I commute on such public transportation. I guess the pandemic (and the eerie realisation that it can repeat anytime, since it was decidedly an artificial one) has attuned me to be more vigilant on my safety and health, so I try to be cautious and safe in public where crowds can gather.

- billynomates 9mo agoHow quickly would this kill bacteria? If 3 people used it in quick succession, it would still transfer bacteria, I imagine?
- rendaw 9mo agoOne thing that I wondered after reading this, it mentions SARS but then it mentions killing bacteria, but SARS is a virus. Does this have any affects on viruses?
- indolering 9mo agoBacteria are larger than viruses, so yes.
- nickdothutton 9mo agoI have copper light switches and other fittings and was interested to learn they have the same useful property.
- deleted 9mo ago[deleted]
- InexSquirrel 9mo agoI was expecting it to just dispense hand sanitiser gel straight onto the handle. I suppose this is a more practical take.
- thenthenthen 9mo agoMany public buildings and elevators in Hong Kong installed wireless controls, simply wave your hand in front of a little hole (ultrasonic sensor?) next to the floor button you want to go to. Curious to find out in which mall they installed this in!
- hombre_fatal 9mo agoAside, it’s obnoxious how many bathroom doors in public places like restaurants require you to pull the door handle to leave. It should be pull to enter, push to leave so that you aren’t fouling your washed hands on the poopy door handle. Even dumber is when they have those foot operated handles to exit. Why is it push to enter, pull to exit at all?
- chedabob 9mo ago> Why is it push to enter, pull to exit at all? So that in an emergency your escape route can't be blocked. Also having doors swing out into corridors is bad practice as you're more likely to open it into someone walking past.
- hombre_fatal 9mo agoGood points. Final draft: bathrooms should have full-length saloon / swing doors split down the middle. Now you can push both directions, and the doors won't arc out enough into the hallway to hit someone.
- AndrewKemendo 9mo agoYes and inward swinging is a building code requirement in most jurisdictions per the ICC https://codes.iccsafe.org/s/IBC2018/chapter-10-means-of-egress/IBC2018-Ch10-Sec1010.1.2 https://codes.iccsafe.org/s/IBC2018/chapter-10-means-of-egre...
