Bicycle Mudguard Fixing Device Elastic U-Shape Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bicycle mudguard fixing devices are impractical, difficult to use, and expensive due to the need for precise sequence of operations, special equipment, and potential damage to the mudguard edge during assembly, often requiring disassembly and specific tools.
Innovation Solution
A device with a partial separation gap between its parts, utilizing counterposed lever arms for pressure application on the mudguard carrying rod, allowing for secure assembly and disassembly without tools, and featuring protrusions for correct positioning and sliding prevention without edge interruption, ensuring structural solidity and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate elements (main body and auxiliary coupling device) are used for fixing the mudguard, then the fixing function is achieved, but the device complexity increases and requires precise sequence of operations
Solution Approach 1:
The patent combines the main body and auxiliary coupling device into a single integrated fixing device. The U-shaped body incorporates both the mudguard holding function and the rod coupling function in one piece, eliminating the need for separate elements and reducing assembly complexity while maintaining reliable fixing functionality
2Reliability
If special equipment is used for secure assembly of the main body to the auxiliary coupling device, then the assembly is secure, but the ease of manufacture decreases and costs increase
Solution Approach 1:
The fixing device is designed to assemble itself through elastic deformation of the U-shaped body. The arms are inserted into the rod ends, causing elastic expansion that automatically secures the coupling without requiring special assembly equipment or tools, thereby simplifying manufacturing while ensuring secure assembly
3Ease of operation
If the edge of the mudguard is opened for insertion of a counterpart, then the fixing device can be attached, but the structural integrity of the mudguard is compromised
Solution Approach 1:
Instead of opening the mudguard edge to attach the fixing device, the patent inverts the approach by having the fixing device's arms pass through the rod ends and secure from the outside. This eliminates the need to compromise the mudguard's edge integrity while still achieving secure attachment through the U-shaped body's elastic coupling mechanism
4Adaptability or versatility
If a partial separation gap is introduced between parts of the fixing device, then elasticity and range of motion are improved, but the structural solidity may be weakened
Solution Approach 1:
The U-shaped body is designed with elastic arms that can deform to accommodate the separation gap while maintaining overall structural integrity. The elastic material and geometry of the arms allow them to flex and return to position, providing the needed elasticity and range of motion without compromising the structural solidity of the entire fixing device
