Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single fitting curve is used for all modular connectors, then the device complexity is reduced, but the manufacturing precision and quality control deteriorate
Solution Approach 1:
The patent divides the pressing operation into multiple independent pressing units, each equipped with its own sensor and control system. Each pressing unit independently monitors and controls the fitting curve for its assigned connector, enabling individualized precision control while maintaining an integrated overall structure.
Solution Approach 2:
The patent implements dynamic control by enabling each pressing unit to independently adjust pressing parameters based on real-time feedback from its sensor. This allows the system to adapt pressing forces and speeds for different connector types, achieving high precision without requiring a completely separate machine for each connector type.
2Manufacturing precision
If different press-fit machines are used for specific modular connectors, then the manufacturing precision is improved, but the productivity decreases
Solution Approach 1:
The patent creates a multi-functional press-fit machine where multiple pressing units can handle different types of modular connectors within a single machine. Each pressing unit is equipped with sensors and control systems that enable it to adapt to different connector types, allowing the machine to perform multiple functions simultaneously and eliminate the need for separate specialized machines.
Solution Approach 2:
The patent combines multiple pressing operations into a single integrated machine. Multiple pressing units operate simultaneously on different connectors within the same production cycle, merging the capabilities of what would traditionally require separate machines into one unified system, thereby increasing productivity while maintaining precision.
3Device complexity
If the same pressing force is applied to all modular connectors, then the device complexity is reduced, but the manufacturing precision deteriorates
Solution Approach 1:
The patent applies local quality control by equipping each pressing unit with its own sensor and control system that independently monitors and adjusts pressing force for its specific connector. This allows each local pressing operation to use optimized force parameters tailored to the specific connector type, rather than applying a uniform pressing force across all connectors.
Solution Approach 2:
The patent implements feedback control where sensors in each pressing unit continuously monitor the pressing force and fit quality, then feed this information back to the control system. The control system uses this feedback to dynamically adjust pressing parameters for each unit, ensuring optimal pressing force accuracy for different connector types.
