Elastic Buffer Cable Fixing Device for Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cables in in-wheel driving devices experience damage due to concentration of tension and stress from vehicle movements, as they lack a separate buffer for stress distribution during upward/downward or side-to-side movements.
Innovation Solution
A cable fixing device with a first and second bracket, each extended linearly and featuring seating grooves, and an elastic buffer to distribute stress, allowing the cable to be seated and reducing tension concentration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate bracket is used to fix the cable, then the cable can be securely attached to the housing, but the cable is damaged by concentration of tension or stress from suspension movement
Solution Approach 1:
A buffer made of elastic material is introduced as an intermediary component between the bracket and the cable. This buffer absorbs and distributes the tension and stress from suspension movement, preventing direct transmission of concentrated forces to the cable while maintaining secure attachment
Solution Approach 2:
The buffer changes the mechanical parameters of the connection by introducing elasticity and compliance. It transforms the rigid connection into a flexible one that can accommodate movement, thereby distributing stress over a larger area and reducing peak stresses on the cable
2Object-affected harmful factors
If multiple components (brackets and buffers) are assembled, then stress distribution is improved, but the fixing operation becomes more complex
Solution Approach 1:
The bracket and buffer are designed to be integrated components that work together as a unified assembly. The buffer is positioned to engage with the bracket in a predetermined manner, creating a combined structure that achieves stress distribution while maintaining relatively simple installation procedures
3Ease of operation
If cables are fixed outside the in-wheel driving device, then access for fixing is improved, but the device structure becomes more complex
Solution Approach 1:
The cable fixing function is segmented from the main in-wheel driving device housing. The bracket assembly is positioned externally where it can be accessed separately, allowing cable installation and maintenance without disassembling the entire device, thereby improving accessibility while maintaining modular simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively distributes stress applied to the cable, enhancing its durability and simplifying the fixing process, while reducing the time required for cable installation.
Implementation Method 1
a buffer installed on at least any one of the first and second brackets, and made of an elastic material to distribute stress transferred to the cable

AI summary
A cable fixing device may include: a first bracket fixed to a housing of an in-wheel driving device, and installed in a shape to cover one side of a cable; a second bracket positioned on the other side of the cable, and fixed to the first bracket; and a buffer installed on at least any one of the first and second brackets, and made of an elastic material to distribute stress transferred to the cable.
