Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disc brake systems suffer from vibrations, juddering, noise, and non-uniform wear of friction material, leading to reduced service life due to the existing brake pads and calipers.
Innovation Solution
A brake pad design with an "Ω"-shaped central portion and support appendages, combined with a caliper featuring "Ω"-shaped seats and spring elements, ensures secure positioning and uniform wear by maintaining the pads in tension during braking, reducing vibrations and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional rectangular brake pads are used, then the structure is simple, but vibrations, juddering and noise occur during braking
Solution Approach 1:
The brake pad is divided into a central portion and multiple support appendages. The support appendages are distributed around the central portion and can pivot independently, segmenting the rigid structure into flexible sub-units that reduce vibration and noise during braking.
2Ease of manufacture
If conventional rectangular brake pads are used, then manufacturing is simple, but non-uniform wear of friction material occurs
Solution Approach 1:
The support appendages are designed to pivot about coupling points, allowing them to dynamically adjust their position during braking. This dynamic movement ensures uniform distribution of friction material wear across the braking band, preventing non-uniform wear patterns while maintaining manufacturing simplicity.
3Ease of operation
If brake pads are coupled at the rearward side and free to pivot, then installation is simple, but service life is reduced due to non-uniform wear
Solution Approach 1:
The pivotable support appendages dynamically adjust during braking operations to maintain optimal contact with the braking band. This dynamic adaptation ensures uniform wear distribution, thereby extending the service life of the friction material while keeping the installation process simple.
Solution Approach 2:
The brake pad structure allows changes in the angular position of support appendages during operation. This parameter change enables the pads to adapt to varying braking conditions, ensuring consistent performance and extended service life.
