Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a protective device is miniaturized to fit confined spaces, then the device size is reduced, but the protection reliability and sealing effectiveness deteriorate
Solution Approach 1:
The protective device is divided into two separate housing elements that can be coupled together. This segmentation allows for compact individual components that can be assembled in confined spaces while maintaining effective sealing through the interface between the two elements. The first housing element accommodates the plug connector and the second housing element accommodates the cable, with both elements working together to provide comprehensive protection.
Solution Approach 2:
The patent employs a nested structure where the first housing element and second housing element are coupled together to form a compact assembly. The plug connector is nested within the first housing element, and the cable is nested within the second housing element. This nesting approach maximizes space utilization while maintaining protection reliability.
2Strength
If a secure and irreversible connection is implemented to prevent damage, then the connection strength is improved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The protective device is segmented into two housing elements that can be separately assembled. This segmentation enables a simple coupling mechanism where the first housing element and second housing element can be easily joined together to form a secure connection. The modular design allows for straightforward assembly while maintaining strong connection strength through the coupling interface.
Solution Approach 2:
The two housing elements are merged through a coupling mechanism that provides both ease of assembly and strong connection. The coupling design allows the first housing element and second housing element to be joined together in a simple manner while creating a secure, irreversible connection that prevents damage to the plug connector and cable.
3Object-affected harmful factors
If a cohesive material connection is used to seal housing elements, then the protection against dust and moisture is improved, but the device complexity increases
Solution Approach 1:
The sealing function is merged into the coupling mechanism between the first housing element and second housing element. The sealing element is integrated with the coupling process, so that when the two housing elements are coupled together, the sealing element automatically forms a cohesive material connection. This integration provides effective dust and moisture protection without adding separate sealing components or complex sealing procedures.
Solution Approach 2:
The sealing element performs self-service by automatically forming a cohesive connection between the housing elements during the coupling process. The sealing mechanism is designed to work autonomously with the coupling action, creating an effective seal against dust and moisture without requiring additional sealing steps or complex sealing systems.
4Strength
If two housing elements are coupled and inseparably connected, then the protection robustness is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The protective device is segmented into two housing elements that can be manufactured separately using standard manufacturing processes. This segmentation simplifies the manufacturing of individual components while the coupling mechanism provides a straightforward assembly process. The first housing element and second housing element can be produced independently and then coupled together to form the complete protective device with robust protection.
Solution Approach 2:
The coupling mechanism merges the two housing elements into a single robust assembly through a simple connection process. This merging approach allows for easy manufacture of individual components while creating a strong, inseparable connection when assembled. The coupling design enables straightforward manufacturing and assembly without requiring complex joining processes.
