Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the brake disc is designed with multiple ribs to reduce weight, then the weight decreases, but the structural strength may be compromised
Solution Approach 1:
The brake disc is segmented into multiple ribs that are integrally connected to both plates. These ribs divide the brake disc into multiple sections, reducing overall weight while maintaining structural integrity through the integral connection design
Solution Approach 2:
The brake disc employs a composite structure combining two plates with multiple ribs integrally connected between them, creating a composite design that optimizes both weight reduction and structural strength through the integration of different structural elements
2Weight of moving object
If the brake disc is designed with ribs for weight reduction, then the weight decreases, but the heat dissipating effect is insufficient
Solution Approach 1:
The brake disc is divided into multiple ribs that create channels between them, segmenting the space for improved air flow and heat dissipation while maintaining weight reduction benefits
Solution Approach 2:
The rib structure creates three-dimensional passageways between the plates, adding vertical dimension to heat dissipation by enabling air flow from the inner surface to the outer surface of the brake disc, enhancing cooling efficiency
3Temperature
If the passageways are made larger for better heat dissipation, then the heat dissipation effect improves, but the structural strength is reduced
Solution Approach 1:
The passageways are segmented into multiple smaller channels between adjacent ribs, distributing the heat dissipation function across multiple pathways while maintaining sufficient structural material in the rib sections
Solution Approach 2:
The rib structure provides localized structural reinforcement at critical positions while creating adequate passageway space in the regions between ribs, achieving local optimization of both strength and heat dissipation

AI summary
A ventilated brake disc includes first and second plates, and a plurality of connecting ribs and protruding ribs. The first and second plates are each shaped as a circular ring, and each have inner and outer surfaces. The inner surfaces of the first and second plates face each other. The first and second plates collectively form a central via and an outer periphery of the ventilated brake disc. Each connecting rib is integrally connected to the inner surfaces of the first and second plates, and elongated in shape, thereby defined with two opposite ends, which are oriented toward the central via and the outer periphery respectively. Each protruding rib protrudes integrally from the inner surface of the first or second plate, and is not connected to the other plate and located between two connecting ribs. The present invention simultaneously attains lightweight and great structural strength and heat dissipating effect.
