Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional detection methods are used to inspect load-bearing core wires, then detection can be performed, but the process is time-consuming and requires multiple rework operations
Solution Approach 1:
The connection device segments the detection process by providing separate electrical connection terminals for each load-bearing core wire. This allows individual wires to be tested independently through the covering layer without requiring complete disassembly or multiple rework operations, thereby reducing detection time while maintaining accuracy.
Solution Approach 2:
The connection device acts as an intermediary component that interfaces with the load-bearing core wires through the covering layer. It provides electrical connection terminals that make contact with the wires without removing the covering layer, enabling accurate detection while avoiding time-consuming disassembly and rework operations.
2Measurement precision
If traditional detection methods are used to inspect load-bearing core wires, then detection can be performed, but operational costs increase due to multiple rework operations
Solution Approach 1:
The connection device enables segmented testing of individual load-bearing core wires through dedicated electrical connection terminals. This segmentation allows for efficient identification of defective wires without requiring complete system disassembly or multiple rework operations, thereby reducing operational costs while maintaining detection accuracy.
Solution Approach 2:
The connection device serves as an intermediary that enables accurate detection of load-bearing core wires through the covering layer without requiring time-consuming and costly disassembly operations. This intermediary approach eliminates multiple rework cycles, reducing operational costs while preserving detection precision.
3Ease of operation
If the covering layer is removed to access load-bearing core wires, then direct inspection is possible, but the structure is damaged and requires rework
Solution Approach 1:
The connection device acts as an intermediary component that provides electrical access to the load-bearing core wires through the covering layer without removing or damaging it. The device includes electrical connection terminals that contact the wires while the covering layer remains intact, ensuring structural integrity is maintained while enabling easy operation for detection purposes.
4Measurement precision
If multiple rework operations are performed for accurate detection, then detection accuracy improves, but time consumption and costs increase
Solution Approach 1:
The connection device segments the detection capability into individual electrical connection terminals corresponding to each load-bearing core wire. This segmentation enables accurate detection of each wire independently through the covering layer in a single operation, eliminating the need for multiple rework operations and thereby improving detection efficiency while maintaining high accuracy.
Solution Approach 2:
The connection device serves as an intermediary that enables accurate detection of all load-bearing core wires simultaneously through the covering layer without requiring multiple rework operations. This intermediary approach achieves both high detection accuracy and improved productivity by eliminating repetitive disassembly and reassembly cycles.
