Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple individual cables are provided for control signals, power, and refrigerant, then each function can be transmitted reliably, but the connection becomes cumbersome and the cable becomes heavy
Solution Approach 1:
The patent combines multiple separate cables (control signal cable, power cable, refrigerant cable) into a single integrated cable assembly. The connector housing integrates receptacles for all three cable types, and the coupling mechanism unifies the connection process. This merging reduces the number of separate connection operations from three to one, directly improving ease of operation while maintaining reliable transmission of all functions through the integrated structure.
2Ease of operation
If the cable is provided in generous length for free positioning, then operational flexibility is improved, but the cable becomes heavy causing operator fatigue
Solution Approach 1:
By merging control signal, power, and refrigerant transmissions into a single integrated cable, the patent reduces the total cable weight compared to three separate cables. The unified cable structure maintains generous length for positioning flexibility while eliminating the redundant weight of multiple separate cable assemblies, thereby reducing operator fatigue.
3Reliability
If thick sheath is provided for safety, then protection is improved, but the cable becomes heavy
Solution Approach 1:
The patent provides a single thick protective sheath around the integrated cable assembly rather than separate sheaths for three individual cables. This unified protective structure maintains safety and protection functions while reducing total weight by eliminating redundant protective layers. The integrated cable requires only one protective envelope, directly addressing the weight issue while preserving safety.
