Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake monitoring systems are costly and require significant assembly effort, as the entire brake pad needs to be replaced if the sensor fails.
Innovation Solution
A pad hold-down arrangement with a holding element and a non-contact temperature measurement sensor element, which can be fixed directly to the holding element, allowing for a cost-effective and low-maintenance monitoring system that can be easily replaced and assembled, particularly suitable for commercial vehicle brake calipers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor element is integrated into the brake pad for monitoring wear level, then the brake condition can be monitored, but the entire brake pad must be replaced if the sensor fails, increasing cost and assembly effort
Solution Approach 1:
The sensor element is separated from the brake pad and integrated into the brake caliper assembly instead. This segmentation allows the sensor to be replaced independently without replacing the entire brake pad, resolving the contradiction between reliable monitoring and ease of repair.
2Reliability
If the sensor element is integrated into the brake pad, then monitoring is possible, but the assembly effort and cost increase significantly
Solution Approach 1:
By separating the sensor element from the brake pad and placing it in the brake caliper assembly, the system allows for independent manufacturing and assembly of components. The sensor can be installed separately during brake caliper assembly without requiring integration into the brake pad itself, reducing overall assembly complexity and cost.
3Measurement precision
If a contact-based sensor is used to measure brake pad wear, then accurate measurement is possible, but the sensor experiences high wear and requires frequent replacement
Solution Approach 1:
The patent replaces contact-based mechanical sensing with a non-contact optical sensor that uses light to detect brake pad wear through the brake disc. This substitution eliminates mechanical wear on the sensor while maintaining measurement precision, resolving the contradiction between accurate measurement and sensor durability.
