Have A Safe Hump

No room for naughty thoughts here, but the explanation for a design simply called the “Safe Hump.” This is no ordinary speed breaker, the system within allows it to harness the mechanical energy (of cars passing over it) into electric energy so that it can power the LEDs. Two reasons why we would want this: 1) LEDs lined speed breakers at night are easily visible from a distance 2) The design of this hump is such that your car glides over it smoothly.

Operating principle:

  • The gear mechanism structure inside the hump facilitates electromagnetic transducer and converts mechanical energy into electric energy, thus supplying energy to the LED within the hump.
  • Better shock absorption by the car thanks to the gear mechanism structure and anti-pressure system. This prolongs the useful life of both the vehicles and humps.

Designers: Zhang Yakun, He Siqian, Zhu Ningning, Chen Chen & Mu Zhiwei

    I don’t think that will deter people from speeding.

  • brack says:

    I think this idea is very close to great potential. I don’t know if I’d concentrate on applying this concept to the speed bump, as most people HATE these things, but the idea of using mechanical energy to enlighten or power something else is a great application. Best of luck.

    Oh man … the word “hump” has certain English meanings that you may want to look at! Maybe “bump” is better.

    I dunno – this looks like it will be very expensive to make. Have you thought about using a piezo-electric device to generate a little electricity, rather than a mechanical linkage that could break? You could make a flasher circuit – even more visible and uses less power, like a bicycle back light.

  • trybudi says:

    great idea! I would have to agree with brian t, will the mechanical links endure over time.

  • J Dizzle says:

    So what you’re saying is that now in addition to the constant “thump thump” that people have to endure when they live in a neighborhood with one of these things, they’ll have some light pollution too? Great! Nice work.
    How will it work in the snow? We’ve already proven that LED’s aren’t hot enough to burn off snow.

    Here’s a better idea. Make a speed bump that retracts when the oncomming car is actually going the correct speed!

  • mif991 says:

    Agree with Brian t…and the mechanisms would break in no time.

  • frezzingaces says:

    usually when people put down these temporary humps it is to cover and protect some cables on the road, with this design you cant

  • did not address snow, ice, dirt, candy wrappers etc.Now lets look at the cost, as drawn its 4-5 k dollars, where a asphalt bump costs under a hundred dollars, so its a fail.

    • let me clarify, its a fail even if its cost was only 3x the times of the existing device (asphalt bump). Its totally divorced from the real world environment that it is supposed to perform in.

  • trybudi says:

    i don’t think the cost is the reason it is a fail.

  • Alan says:

    I agree with zippyflounder . The cost rational is not there at all.

    In the long run, this will just cost more problem then solution and more money then savings..

  • reality says:

    whats wrong with reflective strips? why bother with this expensise? its a fail from me

  • clay h says:

    as a bicycleist, i have no problem going over asphalt humps… this looks like it would suck to ride over.the middle of it caves in and there are notches built into it that look perfect for gobbleing up my skinny tire. fail for me…

  • AlienzExist says:

    Fail. An overdesigned, electric speedbump. You’re kidding right? Did you see the light-up, wind-turbine road-reflectors that was posted here a while ago? Same thing, over-engineered, way too complicated and expensive for mass production. And yet another solution to a problem that does not exist.
