Brake Caliper Pin-Guide Assembly for Faster Pad Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake caliper designs require complex and time-consuming maintenance processes due to threaded connections between pad-holding pins and sliding guides, which can lead to contamination risks and increased production costs.
Innovation Solution
A pad-holding pin and sliding guide assembly designed with separate, reversibly connectable pieces that utilize threaded connections only between the pin and guide, avoiding direct connections with the bracket, allowing easier decoupling and reducing processing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If threaded connections are used between pad-holding pins and sliding guides, then the connection strength is improved, but the maintenance complexity and time consumption increase
Solution Approach 1:
The assembly is divided into separate pad-holding pin and sliding guide components that can be independently removed and reinstalled, allowing maintenance without complete disassembly while maintaining threaded connection strength during operation
Solution Approach 2:
The system transitions from a static threaded connection to a dynamic maintenance process where the sliding guide can be temporarily removed from the bracket, enabling quick pad replacement without affecting the structural integrity during normal operation
2Reliability
If threaded connections are used between pad-holding pins and sliding guides, then the connection reliability is improved, but the contamination risk increases
Solution Approach 1:
The sliding guide is extracted from the bracket during maintenance operations, allowing pad replacement without exposing the threaded connection interfaces to contamination, thereby maintaining connection reliability while eliminating contamination risk during service
3Stability of the object's composition
If direct threaded connections with the bracket are used, then the structural rigidity is improved, but the production cost and processing complexity increase
Solution Approach 1:
The connection system is segmented into the bracket, sliding guide, and pad-holding pin as separate components, reducing the need for complex threaded processing in the bracket itself while maintaining structural rigidity through the assembled connection
