Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake caliper parking systems require complex machining operations for rotational and translational connections, leading to high processing costs and time due to the need for locking pins and specialized holes, resulting in a lengthy assembly process.
Innovation Solution
The integration of deforming elements within the reaction element and main support body allows for a direct rotatable and translational connection without additional components, such as pins or screws, by deforming the support portion to form retracted seats, thereby eliminating the need for specialized machining and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If locking pins and specialized holes are used to connect the reaction plate and caliper body, then the rotational and translational integral connection is achieved, but the machining complexity and assembly time increase significantly
Solution Approach 1:
The patent combines the locking pin and hole features directly into the reaction plate structure. The reaction plate is designed with integrated positioning protrusions that mate with corresponding recesses in the caliper body, eliminating the need for separate locking pins and specialized holes. This merging of features reduces the number of components and simplifies the assembly process while maintaining connection reliability.
Solution Approach 2:
The reaction plate is designed to be self-aligning and self-locking through its geometric features. The positioning protrusions and recesses are shaped such that the reaction plate automatically orients itself during assembly and locks into place without requiring additional fastening operations. This self-service mechanism eliminates the need for complex machining and assembly steps while ensuring reliable connection.
2Reliability
If multiple machining operations are performed on the reaction plate and caliper body, then the rotational and translational connections are established, but the processing cost and time increase
Solution Approach 1:
The patent integrates multiple connection functions into a single reaction plate component. The plate incorporates both rotational and translational connection features through its geometric design, eliminating the need for separate machining operations on both the reaction plate and caliper body. This reduces the total number of machining steps while maintaining connection stability.
Solution Approach 2:
The patent changes the geometric parameters of the reaction plate to achieve self-aligning and self-locking behavior. By optimizing the shapes and dimensions of the positioning protrusions and recesses, the design enables reliable connection with minimal machining, reducing both processing time and cost while maintaining connection stability.
3Reliability
If traditional locking pin systems are used, then the reaction plate and caliper body are securely connected, but the assembly process becomes lengthy and complex
Solution Approach 1:
The reaction plate is designed with self-aligning geometric features that enable automatic positioning and locking during assembly. The positioning protrusions and recesses are shaped to guide the reaction plate into the correct orientation and secure it in place without requiring manual alignment or additional fastening operations. This self-service mechanism significantly accelerates assembly while maintaining connection security.
Solution Approach 2:
The patent extracts the locking function from separate locking pin components and integrates it directly into the reaction plate structure. The positioning protrusions on the reaction plate perform the locking function that previously required separate pins, eliminating unnecessary components and simplifying the assembly process while maintaining connection security.
