Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an electronic brake system with electrically operated hydraulic pressure supply device is used to implement various braking functions, then braking control versatility is improved, but system reliability deteriorates when electric components fail
Solution Approach 1:
The brake system is divided into distinct functional blocks: a mechanical unit (first block) containing the master cylinder that can operate independently, and an electronic unit (second block) containing the electrically operated hydraulic pressure supply device. This segmentation allows the mechanical unit to provide backup braking functionality when the electronic unit fails, thus maintaining reliability while preserving the versatility benefits of the electronic control system.
2Volume of moving object
If the electronic unit is disposed integrated with the mechanical unit, then system compactness is improved, but vehicle design freedom deteriorates due to size and installation position limitations
Solution Approach 1:
A connection line serves as an intermediary element that hydraulically connects the mechanical unit (first block) and the electronic unit (second block), allowing them to be disposed at spaced apart positions. This enables flexible installation arrangements within the vehicle according to space availability and design requirements, while still maintaining functional integration through the hydraulic connection.
