Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disk brake rotor systems fail to efficiently dissipate heat generated during braking, which can lead to reduced performance and lifespan.
Innovation Solution
A brake rotor assembly incorporating a cooling member with a greater surface area than the rotor member, positioned between the rotor and hub attachment member, to effectively dissipate heat through conduction and radiation.

Engineering Contradiction Analysis
1Temperature
If a traditional rotor member is used without a cooling member, then the structure is simple, but heat dissipation efficiency is insufficient leading to reduced performance and lifespan
Solution Approach 1:
A cooling member is introduced as an intermediary component between the rotor member and the hub attachment member. This cooling member acts as a heat transfer mediator, conducting heat away from the rotor member through thermal conduction to its outer surface where heat is then dissipated to the environment, thereby resolving the heat dissipation insufficiency without fundamentally altering the rotor's core structure
Solution Approach 2:
The cooling member extends the heat dissipation function from the two-dimensional braking surface to the three-dimensional outer surface of the cooling member. By adding this radial dimension for heat transfer, the system utilizes additional surface area for heat radiation and convection, significantly improving heat dissipation efficiency beyond what the rotor member's braking surface alone could provide
2Duration of action of stationary object
If the rotor member operates without effective cooling, then the structure remains simple, but the rotor's usable life is reduced due to heat accumulation
Solution Approach 1:
The cooling member serves as a thermal mediator that protects the rotor member from heat accumulation. By positioning it between the rotor member and hub attachment member, it continuously conducts heat away during operation, preventing thermal degradation and extending the rotor's usable life without requiring changes to the rotor member itself
Solution Approach 2:
The cooling member provides beforehand thermal protection by being pre-positioned in the heat path between the rotor member and hub attachment member. This proactive heat management prevents heat buildup before it can damage the rotor, effectively cushioning against thermal stress and extending operational lifespan
