Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the number and configuration of ventilation channels are increased to improve cooling efficiency, then heat dissipation performance is improved, but the mass and weight of the disc increase
Solution Approach 1:
The braking band is segmented into two coaxial plates (first plate and second plate) separated by connection-spacer elements, creating multiple ventilation channels between them. This segmentation allows heat dissipation through the gap without requiring a solid disc structure, achieving cooling efficiency while maintaining low weight.
Solution Approach 2:
The invention transitions from traditional radial ventilation channels to a three-dimensional gap structure between two plates. The connection-spacer elements create a volumetric cooling space that utilizes the axial dimension, enabling more effective heat dissipation without increasing the disc's radial or axial footprint that would affect suspension geometry.
2Loss of energy
If the cooling efficiency is increased to dispose of high braking energy, then heat dissipation is improved, but the structural integrity and suspension compatibility are compromised
Solution Approach 1:
The braking band is divided into two plates connected by multiple connection-spacer elements arranged in a circumferential pattern. This segmentation creates ventilation channels for heat dissipation while the distributed connection elements maintain structural integrity by evenly distributing mechanical loads across the braking band.
Solution Approach 2:
The connection-spacer elements have localized functions: they provide structural connection between plates while simultaneously creating ventilation channels. The arched and intermediate sections of the spacer elements are specifically designed to concentrate heat transfer areas and guide airflow, optimizing both cooling and structural properties in different regions.
3Temperature
If the disc structure is modified to improve cooling, then heat dissipation is improved, but the vehicle suspension modifications are required
Solution Approach 1:
The invention creates a three-dimensional gap structure between two plates with connection-spacer elements, utilizing the axial dimension for ventilation. This approach achieves superior cooling performance without increasing the disc's overall diameter or thickness, thereby maintaining compatibility with existing suspension geometry and avoiding suspension modifications.
