Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bicycle stands are heavy, bulky, and lack the ability to reduce their size for convenient carrying and storage, making them impractical for portable use.
Innovation Solution
A collapsible bicycle stand with a movable positioning device and pivotally connected supporting legs that can be stowed within the stand's body, allowing for compact storage and lightweight design while maintaining the ability to support a bicycle upright.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional stand design with four supporting legs is used, then the stand provides stable support for the bicycle, but the stand becomes heavy and bulky, making it difficult to carry and store
Solution Approach 1:
The stand is divided into a body portion and separate supporting legs. The supporting legs can be detached from the body, allowing the main body to be lightweight and compact for carrying, while the legs provide stability when deployed. This segmentation enables the stand to meet both portability and stability requirements.
Solution Approach 2:
The supporting legs are designed to be stored within the body of the stand when not in use. The body contains a storage chamber that accommodates the legs, creating a compact configuration for carrying. When needed, the legs are extended outward to provide support, effectively nesting the legs inside the body during transport.
2Reliability
If conventional stand design with four supporting legs is used, then the stand provides stable support for the bicycle, but the stand becomes bulky and cannot effectively reduce its size for convenient carrying and storage
Solution Approach 1:
The stand structure is segmented into a compact body and detachable supporting legs. The body maintains a small volume for easy storage, while the legs are separated and can be attached only when support is needed. This segmentation allows the main body to have minimal volume while still providing full support functionality when deployed.
Solution Approach 2:
The supporting legs are nested within the body's storage chamber during transport, significantly reducing the overall volume of the stand. The body is designed with internal cavities that accommodate the legs in a compact arrangement, transforming the stand from a bulky four-legged structure to a compact carryable unit.
3Weight of moving object
If the number of supporting legs is reduced to two, then the stand becomes lighter and more compact for carrying, but the support stability may be compromised
Solution Approach 1:
The supporting legs are designed to be dynamically adjustable in position and configuration. They can be extended, retracted, and positioned at optimal angles to provide maximum stability with only two legs. The legs incorporate adjustment mechanisms that allow them to adapt to different ground conditions and bicycle weights, maintaining stability despite the reduced number of legs.

Function Achieved in This Case
The collapsible stand facilitates easy carrying and storage while providing effective support for bicycles, achieving a lightweight and compact solution without compromising stability.
Implementation Method 1
A positioning device is movable in the chamber and selectively lockable at said first and the second end of the body
Implementation Method 2
Two supporting legs, each supporting leg includes a first end being pivotally connected with the positioning device and a second end adapted to abut against a supporting surface

AI summary
A collapsible stand for bicycle includes a body having a first end, a second end, and a chamber which can receive a crank of a bicycle. A positioning device is movable in the chamber and selectively lockable at the first and the second end of the body. Two supporting legs, each supporting leg includes a first end being pivotally connected with the positioning device and a second end adapted to abut against a supporting surface, wherein the supporting legs are received in the body when the positioning device is at first end of the body, wherein the supporting legs are exposed from the body when the positioning device is at second end of the body.
