Interlocking Brake Cable Guide for Saddle-Type Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interlocking brake structures for saddle-type vehicles face challenges in suppressing excessive displacement of the curved portion of the interlocking brake cable while maintaining its degree of freedom of flexure, leading to potential mechanical issues and inefficiencies.
Innovation Solution
The interlocking brake structure incorporates a plate-like member with ribs to guide the curved portion of the brake cable, ensuring it is securely held without restricting its flexure, using existing components to minimize costs and protect the cable from vibrations and external elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the curved portion of the interlocking brake cable is left unsupported to ensure freedom of flexure, then the cable can move freely, but excessive displacement occurs causing mechanical issues
Solution Approach 1:
A guide member is introduced as an intermediary component between the brake cable's curved portion and the vehicle body. This guide member provides a controlled path for the cable to follow, allowing flexure while preventing excessive displacement that would occur if the cable were completely unsupported.
Solution Approach 2:
The guide member changes the physical parameters of the cable's movement by providing a constrained path. Instead of free movement in all directions, the cable's displacement is parameterized along a specific trajectory defined by the guide member's geometry, ensuring controlled flexure without excessive displacement.
2Reliability
If clamps are used to support the brake cable on the vehicle body frame, then the cable is secured, but the flexure of the curved portion is restricted
Solution Approach 1:
The guide member serves as an intermediary that replaces traditional clamps. Instead of rigidly fixing the cable at discrete points like clamps do, the guide member provides continuous support along the cable's path, securing the cable while allowing it to flex along the intended trajectory.
Solution Approach 2:
The guide member is provided with multiple guide portions that segment the support function along the cable's path. Each guide portion handles a specific section of the cable's curved portion, providing localized support that maintains overall cable security while preserving flexure freedom in each segment.
3Reliability
If multiple separate components are used to support and guide the brake cable, then the cable is well-supported, but the device complexity increases
Solution Approach 1:
Multiple guide portions that would traditionally require separate components are merged into a single integrated guide member. This guide member is attached to the vehicle body as one unit, providing comprehensive support for the cable's curved portion while reducing the total number of components needed in the system.
Solution Approach 2:
The guide member performs multiple functions simultaneously: it supports the cable, guides its movement, prevents excessive displacement, and protects the curved portion. This multi-functional design eliminates the need for separate components for each function, reducing overall device complexity while maintaining reliable cable support.
