Bicycle Lever Pad With Cable Catch for Frayed Cable End Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle control devices for mechanisms like dropper seat posts are difficult to actuate directly due to their location, and the actuation cables require trimming and protection from fraying ends, which can be cumbersome and costly with traditional cable end crimps that may fall off during use.
Innovation Solution
A control device with a lever arm assembly and cable catch system that secures the actuation cable, allowing for remote actuation and protecting the user from frayed ends without the need for additional cable end crimps, by incorporating a cable catch that removably retains the cable tail and features a tip concealing region to prevent contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable end crimps are used to protect actuation cable ends, then cable end protection is achieved, but installation complexity increases and crimps may fall off during use
Solution Approach 1:
The cable catch is integrated into the lever pad structure, merging the cable retention function with the existing lever pad component. This eliminates the need for separate cable end crimps and reduces installation steps while maintaining reliable cable protection.
Solution Approach 2:
The cable catch acts as an intermediary structure between the cable end and the lever arm, providing a built-in retention mechanism that prevents cable ends from fraying or detaching without requiring external crimps.
2Object-affected harmful factors
If cable end crimps are used to protect frayed ends, then cable protection is achieved, but additional components and cost are required
Solution Approach 1:
The cable catch is integrated into the lever pad structure, merging the cable retention function with the existing lever pad component. This eliminates the need for separate cable end crimps and reduces installation steps while maintaining reliable cable protection.
Solution Approach 2:
The lever pad is designed to perform multiple functions: it provides the lever arm function for cable actuation and simultaneously incorporates a cable catch to protect and retain the cable end, eliminating the need for separate protection components.
3Reliability
If cable end crimps are used, then cable protection is achieved, but installation time and cost increase
Solution Approach 1:
The cable catch structure is pre-integrated into the lever pad during manufacturing, so that the cable protection mechanism is already in place before installation. This eliminates the need for separate cable end crimping steps during bicycle assembly or maintenance.
Solution Approach 2:
The cable catch is integrated into the lever pad structure, merging the cable retention function with the existing lever pad component. This eliminates the need for separate cable end crimps and reduces installation steps while maintaining reliable cable protection.
