Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydraulic brake system and mechanical brake system are provided separately with independent hydraulic pressure circuits, then braking functionality is achieved, but manufacturing cost increases and device size increases
Solution Approach 1:
The patent merges the hydraulic brake system and mechanical brake system by integrating the hydraulic pressure circuit with the mechanical brake operation. The master cylinder is configured to receive operation force from the mechanical brake wire, and the hydraulic pressure generated is supplied to hydraulic wheel brakes, creating a unified system where one brake operation controls both hydraulic and mechanical braking functions simultaneously.
Solution Approach 2:
The mechanical brake operator is designed to serve dual functions: directly operating the mechanical brake through the brake wire and simultaneously generating hydraulic pressure through the master cylinder to activate the hydraulic brake system. This multi-functionality eliminates the need for separate brake operators and hydraulic pressure circuits for each system.

AI summary
A brake device (U1) is provided with a hydraulic brake system (K1) which causes a front wheel side wheel brake (F) to generate a braking force, and a mechanical brake system (K2) which directly operates a rear wheel side wheel brake (R) to generate a braking force. The brake device is also provided with a detecting means (31) for detecting the braking force of the rear wheel side wheel brake (R), and a control device (7). The control device (7) operates a pump (6) in accordance with the detection result from the detecting means (31). With this configuration, manufacturing costs can be suppressed and a reduction in size can be achieved.
