Brake Caliper Pin Assembly Without Separate Pin Clips
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake apparatuses for vehicles require multiple components and complex assembly processes, leading to increased manufacturing costs and laborious assembly times.
Innovation Solution
A brake apparatus with reduced components, featuring a caliper body with integrated coupling holes for screw-coupling pin members, eliminating the need for pin clips and simplifying the assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pin clips are used to mount pin members in the caliper body, then the pin members can be securely mounted, but the number of components increases and manufacturing costs increase
Solution Approach 1:
The pin member and pin clip functions are merged into a single integrated pin member component. The pin member includes an insertion portion that fits into the caliper body and a coupling portion with external threads that screw into the caliper body, eliminating the need for separate pin clips while maintaining secure mounting capability
Solution Approach 2:
The pin member is designed with multi-functionality: the insertion portion provides positioning and support, the coupling portion provides secure attachment through threading, and the pin head provides leverage for installation and removal. This single component performs multiple functions that previously required separate parts
2Reliability
If pin clips are used to mount pin members, then the pin members can be securely coupled, but the assembly and disassembly processes become complex and laborious
Solution Approach 1:
The coupling mechanism is simplified by combining the positioning function and fastening function into a single screw-coupling action. The pin member is inserted into the caliper body and then secured by screwing the coupling portion into the threaded hole, eliminating the need for separate clip installation steps
Solution Approach 2:
The mechanical clip-based retention system is replaced with a screw-threaded fastening system. This substitution allows for easier assembly and disassembly through simple rotational motion, replacing the complex multi-step clip installation and removal processes
3Adaptability or versatility
If multiple components are used in the brake apparatus, then the functional requirements can be met, but the manufacturing costs increase
Solution Approach 1:
Multiple components (pin member and pin clip) are merged into a single pin member component, reducing the total number of parts that need to be manufactured, inventoried, and assembled. This integration maintains all necessary functions while reducing manufacturing complexity and cost
Solution Approach 2:
The pin member is designed as a universal component that performs multiple functions: positioning, support, and secure fastening. This multi-functional design eliminates the need for separate specialized components, reducing overall manufacturing costs while meeting all functional requirements

AI summary
A brake apparatus for a vehicle may include: a first brake pad configured to press a brake disc; a second brake pad disposed to face the first brake pad and coming into contact with the brake disc; a pressing part configured to press the first brake pad to move toward the second brake pad; a caliper body on which the pressing part is mounted and enclosing the first brake pad and the second brake pad; and a pair of pin members that are screw-coupled to the caliper body so as to be separated from each other and configured to pass through the first brake pad and the second brake pad.
