Disc Brake Signal Cable Mounting on Spring Hangers Under Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting devices for signal cables on disc brake spring hangers face issues with durability, ease of assembly, and production costs, particularly in environments with high vibration, where friction-based solutions fail to securely hold the cable, and are often difficult to assemble and require significant space.
Innovation Solution
A mounting device with fastening means that clasp the spring hanger from multiple sides, including an upper contact element and side tabs, along with a cable guide with integrated fastening means, providing a secure and compact solution that reduces installation space requirements and enhances durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If friction-based mounting solutions are used to attach the signal cable to the spring hanger, then the device is easier to manufacture, but the reliability deteriorates in high vibration environments causing the cable to come loose
Solution Approach 1:
The patent replaces friction-based mechanical attachment with a positive engagement clasping mechanism. The fastening means includes contact elements that mechanically interlock with the spring hanger through clasping action, eliminating reliance on friction alone and providing secure attachment even in high vibration environments.
Solution Approach 2:
The contact elements of the fastening means are designed with curved surfaces that conform to the geometry of the spring hanger. This curved geometry enables effective clasping engagement, distributing forces evenly and preventing cable loosening under vibrational loads while maintaining ease of assembly.
2Object-affected harmful factors
If traditional mounting devices are used to guide the signal cable along the spring hanger, then the cable is protected, but the installation space required increases significantly
Solution Approach 1:
The patent combines the cable guide function and the fastening function into a single integrated mounting device. The cable guide is attached to the basic body that already includes the fastening means, eliminating the need for separate mounting components and reducing overall installation space while maintaining cable protection.
Solution Approach 2:
The cable guide is designed as a thin-walled structure that provides adequate mechanical protection for the signal cable while occupying minimal space. The guide channel protects the cable from mechanical influences through its structural form rather than through bulky protective housing.
3Device complexity
If friction-based holders are used to clamp the signal cable, then the device structure is simpler, but the durability deteriorates as the cable may come loose under vibration
Solution Approach 1:
The patent replaces simple friction-based clamping with a more complex but reliable positive engagement clasping mechanism. The contact elements are designed to mechanically interlock with the spring hanger, providing durable attachment that resists vibration-induced loosening while maintaining reasonable structural simplicity.
