Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secondary brake system is added to the primary brake system, then braking safety and redundancy are improved, but the brake apparatus becomes more complex and heavier due to additional pipes and components
Solution Approach 1:
The patent combines the primary brake unit and secondary brake unit into a single integrated brake apparatus. The pump housing accommodates both brake units, and the hydraulic circuit is designed as a unified system with shared components such as the reservoir, pump, and control valves. This integration reduces the number of separate pipes and components, thereby simplifying the overall structure while maintaining the redundancy function of having both primary and secondary brake systems.
