Multi-Tool Elastic Retention for Implement Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple tools for motorcycle and bicycle maintenance lack reliable retention mechanisms, causing implements to accidentally rotate or require cumbersome cases, which are impractical for use and storage.
Innovation Solution
Incorporation of elastic retention means, including compression springs and clamping mechanisms, to securely hold implements in both retracted and operating positions, allowing for easy transition between them without the need for external cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If friction retention is used to hold implements in retracted position, then the structure is simple, but the implements accidentally rotate and move
Solution Approach 1:
The patent changes the retention mechanism from passive friction to active elastic force by introducing compression springs. The springs apply continuous radial force to the implements, transforming the retention principle from relying on friction parameters to relying on elastic force parameters, thereby ensuring reliable retention without increasing structural complexity
Solution Approach 2:
The patent introduces elastic retention means (compression springs and retaining rings) as intermediary elements between the pivot and the implements. These intermediaries mediate the retention function by providing controlled elastic force, allowing the implements to be securely held while maintaining simple overall structure
2Reliability
If a case is used to contain and protect implements, then the implements are securely retained, but the device becomes cumbersome and impractical for quick access
Solution Approach 1:
The patent extracts the retention function from the external case and integrates it directly into the pivot mechanism through elastic retention means. This eliminates the need for separate protective cases, allowing implements to be securely retained while maintaining easy access and portability
Solution Approach 2:
The patent merges the retention function with the structural pivot by incorporating compression springs and retaining rings directly into the pivot assembly. This integration combines the protective case function with the mechanical pivot, eliminating the need for separate cases and improving ease of operation
