Innovative design of energy generation and storage devices based on road speed bumps

Abstract

This paper presents an innovative design that aims to solve the problems of conventional speed bumps. The speed bump is capable of adjusting the cushioning strength in real time according to the speed of the vehicle and is equipped with a power generation facility. When a vehicle passes over the speed bump, the device converts the force exerted by the vehicle into electricity, which is stored in a battery. In low light conditions at night, the LED deceleration warning light provides a warning through the power generation facility, ensuring safe and comfortable driving. In addition, the speed bumps have a sunken design that reduces vehicle bumps, while powering the street lights at night through a sunken drive motor and generator. Each pass can generate 30KJ of electricity, and if 30,000 vehicles pass through each day, it can recover 5,000 watts of electricity per hour, reducing energy loss compared to traditional energy transmission methods. Modular design reduces the system price, low transformation threshold, can be applied to traditional speed bumps, reducing the cost recovery cycle to about one year, expanding the application scope.
