Brake Pad Connector Layout for Uniform Return Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake calipers experience incomplete return operations of brake pads due to uneven force transmission, leading to drag characteristics and braking noise, as the elastic force is primarily applied to the upper portion of the brake pad, failing to transmit effectively to the lower portion.
Innovation Solution
The brake pad and caliper design incorporates symmetrically positioned brake pad connectors with springs, featuring protruding ears and a spring seating groove, ensuring uniform force distribution and guiding the brake pad's movement, enhancing the return operation and reducing drag and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elastic force is applied to the upper portion of the brake pad, then the upper portion returns smoothly, but the force is not transmitted well to the lower portion causing incomplete return operation
Solution Approach 1:
The brake pad connector is divided into multiple segments: a body portion, a protruding ear extending from it, and multiple springs (first spring and second spring) positioned at different locations. This segmentation allows elastic force to be applied at multiple points (upper and lower portions) simultaneously, ensuring both the upper and lower portions of the brake pad return smoothly and completely without force transmission gaps.
2Reliability
If conventional brake caliper structure is used, then the brake pad can be supported, but the structure is complex and space efficiency is reduced
Solution Approach 1:
The brake pad connector merges multiple functions into a single integrated component: it provides structural support for the brake pad, guides the brake pad's movement through the protruding ear, and stores elastic energy through the springs. This consolidation eliminates the need for separate support structures and guide mechanisms, simplifying the brake caliper structure while improving space efficiency inside the caliper housing.
Solution Approach 2:
The brake pad connector serves multiple purposes: it acts as a support structure, a guide mechanism, and a spring mounting platform. The protruding ear simultaneously guides brake pad movement and provides a mounting point for the springs. This multi-functionality reduces the overall component count and structural complexity of the brake caliper system.

AI summary
The present disclosure relates to a brake pad, a brake caliper equipped with the brake pad, and a vehicle equipped with the brake caliper. The brake pad may include two brake pad connectors symmetrically positioned with respect to a center of a brake pad surface and connected to the caliper body by springs. Reliability of a return operation of the brake pad is secured, thereby reducing drag and braking noise.
