Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake discs for cycles and motorcycles fail to effectively disperse heat generated during braking, leading to excessive heat retention.
Innovation Solution
A brake disc design featuring an outer ring with periodically arranged recesses on its surfaces, forming geometric sinusoidal patterns that facilitate heat dispersion both perpendicular and radially outward, preventing heat from being trapped inside the disc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional brake disc design is used, then the structure is simple, but heat dissipation is insufficient
Solution Approach 1:
The brake disc is segmented into multiple functional zones: an outer ring with periodic recesses for radial heat dispersion, an inner ring with circumferential grooves for axial heat dispersion, and a central hub. This segmentation allows different regions to specialize in different heat dissipation directions, effectively resolving the contradiction between simple structure and sufficient heat dissipation.
Solution Approach 2:
The invention introduces a dual-dimensional heat dissipation approach: radial dispersion through recesses in the outer ring and circumferential dispersion through grooves in the inner ring. This multi-dimensional heat transfer pathway significantly improves heat dissipation efficiency without requiring a completely complex structure.
2Reliability
If heat is trapped inside the disc, then the disc structure remains intact, but braking performance deteriorates
Solution Approach 1:
The invention extracts heat from the brake disc by creating dedicated heat dissipation pathways. The periodic recesses in the outer ring and circumferential grooves in the inner ring act as heat extraction channels, actively removing trapped heat and preventing it from degrading braking performance.
Solution Approach 2:
The recesses and grooves serve as intermediary structures that facilitate heat transfer from the friction surfaces to the surrounding environment. These intermediate features mediate between the heat generation at the friction interface and the heat dissipation to the ambient air, preventing heat accumulation that would compromise braking reliability.
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 enhances heat dissipation during braking, reducing the temperature of the brake disc and improving braking performance by effectively directing heat away from the disc.
Implementation Method 1
a heat generated during braking is dispersed at least in a direction perpendicular to the outer ring both to the front and to the rear
Implementation Method 2
each recess of said multiplicity of recesses is formed along said outer edge in order to disperse the heat generated by the brake in a radial direction to the outside of the outer ring
