Brake Pad Backing Plate Cutouts for Better Heat Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake pads for bicycle and motorbike disc brake assemblies face inefficiencies in heat dissipation, leading to brake fading during prolonged descents due to limited thermal conduction and radiation capabilities of steel backing plates, and inadequate air flow through radiators.
Innovation Solution
A brake pad design featuring a backing plate extension with inclined cutouts that maximize convection and radiation surface areas, allowing for free air movement and enhanced heat emission, where the cutouts are preferably inclined at 30° to 60°, most effectively at 45°, to direct heat away from opposing surfaces and increase the overall surface area for thermal dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a steel backing plate is used for the brake pad, then stability and stiffness are improved, but heat dissipation capability deteriorates due to limited thermal conduction
Solution Approach 1:
The patent extends the backing plate in a radial direction away from the disc brake rotor, adding a dimensional element that increases the surface area available for heat dissipation without compromising the structural stability of the original steel backing plate
2Temperature
If a groove is added to the backing plate for heat dissipation, then ventilation is improved, but the amount of heat dissipation remains limited
Solution Approach 1:
Instead of merely adding grooves to the existing backing plate surface, the patent creates a radial extension that projects outward in space, significantly increasing the heat dissipation surface area in a new dimensional direction rather than just modifying the existing two-dimensional surface
3Temperature
If the backing plate is extended radially away from the disc brake rotor, then heat dissipation surface area is improved, but the structure becomes more complex
Solution Approach 1:
The backing plate is divided into two functional segments: the original structural portion that maintains stability and the radial extension portion that is optimized for heat dissipation. This segmentation allows each part to fulfill its specific function without compromising the other
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design significantly improves heat dissipation by maximizing convection and radiation, reducing brake fading and maintaining braking power, while maintaining stability and stiffness with a metal backing plate.
Implementation Method 1
A further type of heat transfer is convection by means of which the thermal energy is transferred through the movement of air around the backing plate acting as a radiator
Implementation Method 2
A further type of heat transfer is the transfer of the thermal energy through the thermal radiation by means of electromagnetic waves emission from the surface
Implementation Method 3
One type of heat transfer is conduction which is the transfer of the thermal or heat energy through direct contact between the backing plate and the friction material of the friction pad
