Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation pins are arranged to maximize heat dissipation effect, then heat dissipation performance is improved, but rotational balance deteriorates and turbulent flow increases
Solution Approach 1:
The heat dissipation pins are segmented into multiple groups arranged on different virtual circles (first virtual circle, second virtual circle, etc.) with different numbers of pins in each group. This segmentation allows optimization of heat dissipation surface area while maintaining rotational balance through symmetric distribution of pin groups.
Solution Approach 2:
The pin arrangement uses asymmetric virtual spiral patterns (first virtual spiral patterns and second virtual spiral patterns) that curve in opposite directions from the center. This asymmetric design creates symmetric pin distribution that balances rotational forces while maximizing heat dissipation effectiveness.
2Temperature
If heat dissipation pins are arranged to maximize heat dissipation effect, then heat dissipation performance is improved, but turbulent flow around the disc increases
Solution Approach 1:
The virtual spiral patterns used for pin arrangement follow curved paths rather than straight lines. This curvature in the pin distribution pattern helps guide airflow smoothly around the disc, reducing turbulence while maintaining effective heat dissipation zones.
3Stability of the object's composition
If pins are arranged symmetrically to improve rotational balance, then rotational balance is improved, but heat dissipation effectiveness may be reduced
Solution Approach 1:
The pin arrangement extends into multiple dimensional layers by using pins at different radial distances from the center (on different virtual circles). This multi-dimensional arrangement allows symmetric distribution for rotational balance while creating multiple heat dissipation zones that maintain effectiveness.

AI summary
A brake disc according to one embodiment includes a first disc, a second disc apart from the first disc in an axial direction, and a plurality of pins disposed at intersections of three types of virtual lines and whose one ends are connected to a side of the first disc facing the second disc. The three types of virtual lines are a plurality of virtual circles concentric with the first disc, a plurality of first virtual spiral patterns passing through the center of the first disc and curved rightward when viewed from the axial direction, and a plurality of second virtual spiral patterns passing through the center of the first disc and curved leftward when viewed from the axial direction. In one embodiment, the intersections are arranged symmetrically with respect to an imaginary line connecting any one of the intersections and the center when viewed from the axial direction.
