Vehicle Brake Caliper Plate Coupling Vibration Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle brake calipers experience noise and loosening due to vibrations, causing the plate with manufacturer information to move and separate, which affects the coupling and exterior quality.
Innovation Solution
A caliper design featuring a caliper body assembly, a plate, a spacer, and a fastener, where the spacer maintains a gap between the caliper body assembly and the plate using elastic force, and the fastener couples through specific grooves and holes to prevent movement and enhance exterior quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the plate is coupled to the caliper body assembly, then the plate is secured in position, but vibrations cause the plate to move and separate, causing noise and loosening
Solution Approach 1:
The coupling structure is divided into multiple functional elements: a coupling protrusion on the plate, a coupling groove on the caliper body assembly, and a fastening groove. This segmentation allows the structure to accommodate vibrations while maintaining secure coupling, as each element performs a specific function in the coupling mechanism.
Solution Approach 2:
The coupling protrusion acts as an intermediary element between the plate and the caliper body assembly. It fits into the coupling groove to provide mechanical coupling, while the fastening groove provides additional securing. This intermediary structure prevents direct rigid connection that would be susceptible to vibration-induced loosening.
2Stability of the object's composition
If the plate is tightly coupled to the caliper body assembly, then separation is prevented, but exterior quality deteriorates due to visible coupling components
Solution Approach 1:
The fastening function is extracted from the main coupling structure. The fastening groove is positioned such that the fastening operation occurs internally, away from the exterior view. This allows the coupling to be secure while the exterior surface remains smooth and aesthetically pleasing without visible fastening components.
Solution Approach 2:
The coupling protrusion is nested within the coupling groove, and the fastening groove is integrated into the caliper body assembly structure. This nesting arrangement allows multiple coupling functions to be accomplished within the internal structure, keeping the exterior surface clean and maintaining aesthetic quality while ensuring secure coupling.
3Object-affected harmful factors
If the plate is rigidly fixed to prevent movement, then vibration-induced noise is reduced, but the coupling structure becomes more complex
Solution Approach 1:
The coupling and fastening functions are merged into a single integrated groove structure on the caliper body assembly. The coupling groove and fastening groove work together as a unified coupling system, eliminating the need for separate complex fastening mechanisms while effectively preventing vibration-induced noise.
