Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a disc brake system combines both mechanical and hydraulic braking components, then braking versatility and reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines mechanical and hydraulic braking systems into a single integrated caliper body. The caliper housing contains both a mechanical piston (actuated by cable) and a hydraulic piston (actuated by hydraulic fluid), allowing both braking systems to operate through a unified structure rather than separate components.
Solution Approach 2:
The caliper body is designed to perform multiple functions through a single structure. It can operate in mechanical braking mode, hydraulic braking mode, or both simultaneously, providing universal braking capability that adapts to different riding conditions and maintenance requirements.
2Ease of repair
If the mechanical caliper body is detachably coupled to the hydraulic caliper body, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The caliper is divided into separable modules: a mechanical caliper body and a hydraulic caliper body that can be detachably coupled. This segmentation allows the mechanical portion to be removed and serviced independently from the hydraulic portion, enabling targeted maintenance without complete disassembly.
Solution Approach 2:
The coupling between mechanical and hydraulic caliper bodies is designed to be dynamically changeable - firmly connected during operation for reliable braking, but easily detachable during maintenance. The fixing members allow the structure to transition between connected and separated states based on operational needs.
3Volume of moving object
If offset attachment portions are used to achieve compact configuration, then volume is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The attachment portions are positioned at offset locations rather than symmetrically opposite each other. This asymmetric, offset arrangement allows the mechanical and hydraulic components to be packed more efficiently in three-dimensional space, reducing the overall caliper volume while maintaining functional separation.
