What is a good real world example of this? Maybe something like a spring loaded system which takes force to load but then is released with simple trigger.
- joncrane 6y agoA very powerful weapon? Should be difficult to arm but easy to defuse.
- double0jimb0 6y agoSome of the latches on expensive coolers are intentionally hard to close, leading users to slam them, which leaves the user with the feeling of the cooler/latch being rugged (and hopefully worth the extra price of admission). These slam latches are much easier to open than to close.
- dandelany 6y agoSurely it’s not just to “feel rugged”. The rubber seal of a cooler lid is essentially a deformable spring which must be compressed in order to form an effective seal.
- chrisseaton 6y agoWhen you're closing a cooler you're compressing the gasket. When you open it you're releasing the gasket. It's not a cynical marketing ploy like you describe - it's functional.
- double0jimb0 6y agoI encourage you to validate your assertion at your local sporting goods store (comparing tactile feedback against price point). Don't worry, that Yeti is still a great cooler (I jest, I jest) Source: I engineer tactile mechanisms to price points for a living.
- chrisseaton 6y agoI don't know what you mean sorry? I don't know what differs at price points, and I don't know what Yeti is. I just know the coolers I have have gaskets which get compressed when you close them. That's why they pop open when I unlatch them, and why it takes effort to close them.
- LukeShu 6y agoYou asserted > It's not a cynical marketing ploy like you describe - it's functional. I believe the parent comment is saying that the closing-force varies closely with price; as price goes up, so does the force required to close it. While there may be a functional reason for some difference between opening-force and closing-force, you wouldn't expect that functional reason to result in that correlation so strongly, and that the majority of the difference in force at high price points is a cynical marketing ploy. (I'm not sure I buy that, it makes sense to me that a more expensive cooler has a thicker gasket to get a better seal.) Yeti is a well-known expensive brand of coolers.
