Car Caliper Cover Fixing Structure for Stable Direct Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caliper covers suffer from indirect fixation methods that lead to loose fittings, complex installation processes, insufficient clamping force, and poor heat dissipation, compromising safety and efficiency.
Innovation Solution
A direct fixation structure using a combination of first and second fixing members with bent portions connected by bolts and nuts, along with an aluminum alloy construction and electrostatic powder coating, enhances clamping force and installation ease, while an elastic pressing sheet aids in heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If indirect fixation with buckles relying on clamping force is used, then the caliper cover can be installed, but the fixation structure will loosen over time
Solution Approach 1:
The fixation structure is divided into multiple independent fixing members (first fixing member with first bent portion, second fixing member with second bent portion) that work together. Each fixing member independently engages with the caliper body through its bent portion, distributing the fixation force and preventing loosening that occurs with single-buckle indirect fixation.
Solution Approach 2:
The bent portions extend in multiple directions (first bent portion in first direction, second bent portion in second direction) to engage with different surfaces of the caliper body. This multi-dimensional engagement creates a more stable fixation that resists loosening from vibration and thermal expansion, unlike the linear clamping force of traditional buckles.
2Reliability
If two buckles are used for fixation, then the caliper cover can be secured, but the installation process becomes difficult and time-consuming
Solution Approach 1:
The bent portions are pre-formed during manufacturing with the correct geometry and orientation. This preliminary shaping eliminates the need for complex field adjustments and alignment during installation, allowing technicians to simply position and secure the fixing members without time-consuming manipulation.
Solution Approach 2:
The bent portions are designed to self-align and self-eng age with the caliper body surfaces through their geometric configuration. The first bent portion automatically orients in the first direction and the second bent portion in the second direction, eliminating the need for precise manual alignment that makes traditional buckle installation difficult and time-consuming.
3Device complexity
If small buckles with limited clamping force are used, then the structure is simple, but the fastening force is insufficient causing deformation
Solution Approach 1:
The bent portions utilize curved geometries that distribute clamping force over larger surface areas of the caliper body. This curved engagement increases the effective contact area compared to small linear buckles, providing sufficient fastening force without requiring complex multi-component structures.
Solution Approach 2:
The fixing members are designed with optimized dimensions and material properties to achieve the required clamping force. By changing parameters such as the bend radius, thickness, and material strength of the bent portions, sufficient fastening force is achieved while maintaining structural simplicity and avoiding the need for multiple small buckles.
