Structural Design and Experiment of a Vertical Bicycle Parking Device Based on TRIZ Theory

Aiming at the problem of complicated parking process, time-consuming, inconvenient operation and high cost of vertical bicycle parking device, based on TRIZ theory, the contradiction matrix was used to find the corresponding TRIZ inventive principles. The working principle and structure for the vertical parking bicycle device were studied. A new vertical bicycle parking device was proposed. It was mainly composed of bicycle parking frame, lifting mechanism, clamping mechanism, switching mechanism and intelligent lock. The functions of automatic clamping and loosening of the front wheel of the bicycle, vertical parking and bicycle anti-theft were realized, using the force of multiple springs, linear guide and slider, lever principle and some special-shaped parts. A virtual prototype for motion simulation and stress analysis were designed by using SolidWorks to verify the rationality of structural design. The physical prototype was manufactured. The experimental results show that the device is easy to operate, the parking time is 3 ~ 5 seconds, saving about 40% parking space, lifting mechanism to help reduce energy consumption, which has a good practical value and promotion significance.
