Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If mass distribution is modified to reduce squeal noise, then noise characteristics are improved, but manufacturing complexity and cost increase due to elaborate casting procedures
Solution Approach 1:
The brake caliper is divided into separate components (caliper housing, caliper bracket, connecting means) that can be manufactured independently using standard casting procedures. The mass distribution is adjusted by selecting different mass configurations of the connecting means rather than modifying the overall caliper shape, thereby avoiding complex manufacturing while achieving noise reduction.
Solution Approach 2:
The invention changes the mass parameter of the connecting means (first and second connecting means) to optimize noise characteristics. By providing different mass configurations of the connecting means that couple the caliper bracket to the caliper housing, the patent achieves effective squeal noise suppression without modifying the geometric shape or requiring elaborate casting procedures of the main components.
2Object-affected harmful factors
If computer-aided engineering is used to optimize mass distribution, then noise reduction is improved, but development time and cost increase
Solution Approach 1:
The patent provides predefined mass configurations for the connecting means that can be directly implemented without requiring extensive computer-aided engineering analysis. The connecting means are designed with specific mass relationships (first connecting means having different mass than second connecting means) that are proven to suppress squeal noise, allowing manufacturers to quickly implement noise reduction by selecting appropriate pre-designed components.
3Object-affected harmful factors
If the shape of caliper bracket or housing is modified to reduce noise, then noise characteristics are improved, but manufacturing cost and time increase
Solution Approach 1:
Instead of modifying the overall shape of the caliper bracket or housing, the invention introduces local mass variations specifically in the connecting means that interface between components. This localized approach to mass distribution optimization allows noise reduction to be achieved by modifying only the connecting elements rather than redesigning the entire caliper structure, thereby avoiding increased manufacturing cost and complexity.
