Dual-Function Bicycle Stand With Segmented L-Shaped Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle stands lack versatility in supporting both complete bicycles and bicycle frames without rear wheels, and there is a need for improved security during transportation to reduce damage risks.
Innovation Solution
A dual-function bicycle stand with L-shaped leg elements, where one leg supports the bicycle and the other securely fixes the bicycle frame using a frame receiving element with cylindrical openings for quick release hubs or chain stays, allowing it to be used as both a bicycle stand and a transport container attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bicycle stand is designed to support only complete bicycles with rear wheels, then the support function for bicycles is achieved, but the ability to support bicycle frames without rear wheels is lost
Solution Approach 1:
The bicycle stand is designed with dual functionality: the first leg element supports complete bicycles (with rear wheels) while the second leg element with frame receiving element supports bicycle frames without rear wheels. This multi-functional design allows a single stand structure to serve multiple purposes, resolving the contradiction between versatility and complexity by integrating both functions into one unified device rather than requiring separate stands for each function.
2Reliability
If a bicycle stand uses a simple L-shaped structure, then the manufacturing is easy and cost is low, but the security and stability during transportation is insufficient
Solution Approach 1:
The stand is segmented into distinct functional elements: a first leg element for ground contact and bicycle support, a second leg element with a frame receiving element for frame fixation. This segmentation allows each component to be optimized for its specific function while maintaining overall structural integrity. The segmented design enhances reliability during transportation by providing dedicated support points without requiring overly complex manufacturing processes.
Solution Approach 2:
The frame receiving element acts as an intermediary component that securely connects the bicycle frame to the stand structure. This intermediary element provides the necessary security and stability during transportation while maintaining a relatively simple overall structure that is easy to manufacture. The receiving element serves as a mediator between the frame and the ground-contacting leg, ensuring stable support without complex assembly requirements.

AI summary
A bicycle and bicycle frame stand includes a first leg element and a second leg element which forms an angle of less than or equal to 90° with the first leg element. The second leg element has a bicycle receiving element for a bicycle component of an assembled bicycle, and the second leg element has a frame receiving element for a bicycle frame component.
