Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake disks suffer from reduced structural strength due to heat dissipation holes, leading to deformation or breakage under high friction heat, compromising brake safety and increasing the risk of accidents.
Innovation Solution
A brake disk design featuring a body with heat dissipation members on either side of the central axis, connected via fixing portions, which enhances heat dissipation efficiency and structural strength by transmitting friction heat away from the brake portion while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation holes are added to the brake disk, then heat dissipation efficiency is improved, but structural strength is reduced
Solution Approach 1:
The brake disk is segmented into a body and separate heat dissipation members that can be assembled together. The heat dissipation members are detached from the main body through assembly, allowing the body to maintain its structural integrity while the heat dissipation members provide thermal management functionality.
Solution Approach 2:
Heat dissipation members act as intermediary components between the brake portion and the external environment. These members receive heat from the brake portion through thermal conduction and dissipate it to the surrounding air, serving as a mediator that protects the main body from direct thermal stress.
2Temperature
If more heat dissipation structures are added, then heat dissipation efficiency is improved, but device complexity increases
Solution Approach 1:
The heat dissipation members serve multiple functions: they provide thermal conduction pathways, act as additional heat dissipation surfaces, and function as structural reinforcement elements when assembled to the body. This multi-functionality reduces the need for separate components for each function.
Solution Approach 2:
The heat dissipation functionality is merged with the structural components through the assembly of heat dissipation members to the body. Rather than integrating complex internal heat dissipation structures, the design combines separate but functionally integrated components.
