Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for smaller, less expensive, easier to use, and easier to manufacture adjustable bicycle stands that are compact, portable, lightweight, and simple to assemble, capable of accommodating different bicycle tire widths.
Innovation Solution
An adjustable bicycle stand design featuring a pair of base members with spaced slots and adjustable upright members supported by angled support members, allowing for easy adjustment without the need for tools, made from high-grade thermoplastic or similar materials, with all components being of the same configuration to reduce manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional adjustable bicycle stands are designed to accommodate different tire widths, then adaptability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The bicycle stand is divided into separate modular components: base members with slots, upright members with channels, and support members with tabs. These segmented parts can be independently manufactured and assembled in various configurations to accommodate different tire widths, reducing overall design complexity while maintaining versatility.
Solution Approach 2:
The base members, upright members, and support members are designed with universal connection features (slots, channels, tabs) that allow the same components to be used in multiple configurations. This multi-functionality enables a single set of standardized parts to accommodate various tire widths, reducing the need for multiple specialized stands.
2Adaptability or versatility
If traditional adjustable bicycle stands use complex adjustment mechanisms, then adaptability is improved, but ease of manufacture and assembly deteriorates
Solution Approach 1:
The adjustment mechanism is segmented into simple, standardized connection elements (slots, channels, tabs) that can be easily manufactured using conventional methods. Each component has a specific, simple function, making the overall assembly straightforward and cost-effective to produce.
Solution Approach 2:
The support members are designed to self-position and self-secure within the upright members and base members through their tab-and-slot connection system. This self-aligning mechanism eliminates the need for complex adjustment procedures or specialized tools, making assembly intuitive and rapid.
3Reliability
If traditional adjustable bicycle stands are designed for stability, then reliability is improved, but weight and portability deteriorate
Solution Approach 1:
The stand is constructed from separate, lightweight components that can be assembled only when needed. The modular design allows for minimal material usage while maintaining structural integrity during use, and enables easy disassembly for portability, reducing overall weight compared to monolithic designs.
Solution Approach 2:
The connection system uses dynamic tab-and-slot interfaces that provide rigid support when assembled but allow easy disassembly. This dynamic characteristic enables the stand to transition between a stable, rigid configuration during use and a compact, portable state for storage and transport.

AI summary
An adjustable bicycle stand includes a pair of forward and rearward base members and a pair of right and left upright members supporting a bicycle wheel therebetween. Each upright member extends between both the forward and rearward base members. At least one of the upright members is adjustable relative to the forward and rearward base members.
