Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary wheels for bicycles are unstable, lack adjustability, and fail to adapt to different bicycle types, posing a risk of falling and injury, especially for beginners.
Innovation Solution
An auxiliary wheel installation bracket with a fixed and adjustable installation system, comprising multiple interconnected parts that allow for secure attachment to the rear wheel fork rods and adjustable height settings, enhancing stability and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple fixing piece is used to connect auxiliary wheels to the bicycle, then the device complexity is reduced, but the connection stability deteriorates
Solution Approach 1:
The installation bracket is divided into multiple segments: a fixed installation part that attaches to the bicycle frame and an adjustable installation part that connects to the auxiliary wheel. This segmentation allows each part to be optimized independently - the fixed part provides stable mounting while the adjustable part enables height customization, resolving the contradiction between simple structure and stable connection.
Solution Approach 2:
The bracket incorporates adjustable components with multiple adjustment holes and detachable connections, transforming a static simple structure into a dynamic adaptable one. The adjustable installation part can be positioned at different heights and angles, providing connection stability for various bicycle types and user needs while maintaining relatively simple overall structure.
2Manufacturing precision
If a fixed single-height auxiliary wheel system is used, then the manufacturing precision requirements are reduced, but the adaptability to different user needs deteriorates
Solution Approach 1:
The adjustable installation part features multiple adjustment holes at different heights and positions, allowing the bracket to be configured for various auxiliary wheel sizes and user requirements. This dynamic adjustability provides versatility without requiring high manufacturing precision, as the system can accommodate variations through selective positioning rather than tight tolerances.
Solution Approach 2:
The bracket design serves multiple functions: it can accommodate different auxiliary wheel sizes, adjust to various heights, and adapt to different bicycle frame geometries. The combination of fixed and adjustable parts creates a universal mounting solution that works across different应用场景 while maintaining simple manufacturing requirements.
3Adaptability or versatility
If an adjustable installation part with multiple connection points is added, then the adaptability to different bicycle types is improved, but the device complexity increases
Solution Approach 1:
The bracket is segmented into a fixed installation part with mounting holes for the bicycle frame and an adjustable installation part with connection holes for the auxiliary wheel. This segmentation allows the fixed part to handle frame-specific variations while the adjustable part standardizes the wheel connection, achieving broad compatibility without proportionally increasing overall complexity.
Solution Approach 2:
Rather than making the entire bracket fully adjustable and complex, the design applies adjustability only where needed - specifically in the installation part that contacts the auxiliary wheel. The fixed installation part remains simple and stable, providing partial adjustment that is sufficient for achieving compatibility across different bicycle types without excessive complexity.
