Composite Cable Signal Superposition for Reduced Diameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of signal lines in composite cables for electric brakes leads to a larger cable diameter, making it difficult to accommodate them in vehicle architectures, particularly in designs where space is limited.
Innovation Solution
Integrating the signal lines for the wheel velocity sensor and motor sensor into a single superimposed signal and connecting the wheel velocity sensor directly to the subsidiary electronic control unit, allowing the main electronic control unit to read information prioritized by importance, thereby reducing the cable diameter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of signal lines in the composite cable is increased to accommodate more sensors and improve control function, then the control function and measurement capability are improved, but the cable diameter becomes too large to be disposed in the vehicle
Solution Approach 1:
The patent combines multiple signal lines (motor control signals and wheel velocity sensor signals) into a single composite cable by using a multi-core cable structure where multiple functions are integrated into one cable assembly, thereby reducing the overall space requirement while maintaining all necessary communication channels
Solution Approach 2:
The composite cable is designed to serve multiple functions simultaneously - it carries both motor control signals and wheel velocity sensor signals through a single cable structure, making the cable a multi-functional component that addresses multiple communication needs without requiring separate cables for each function
