Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wiring information with non-uniform description formats is used for wire harness design, then the design process becomes difficult and time-consuming, but converting all wiring information to a uniform format increases processing complexity
Solution Approach 1:
The patent introduces an intermediary component (format conversion unit) that acts as a mediator between the diverse wiring information sources and the wire harness design system. This intermediary automatically converts various description formats into a standardized format, resolving the contradiction by handling format diversity without requiring the design system itself to become complex.
Solution Approach 2:
The patent applies parameter changes by transforming the format parameters of wiring information (description position, order, symbols) into a standardized set of parameters. This allows the system to accept diverse input formats while maintaining consistent internal processing, thus improving ease of operation without permanently increasing system complexity.
2Manufacturing precision
If manual processing of diverse wiring information formats is performed, then design accuracy can be maintained, but the time required for design increases significantly
Solution Approach 1:
The patent replaces the mechanical/manual process of format conversion with an automated computational system. The format conversion unit automatically parses and transforms wiring information from various formats, substituting manual processing with algorithmic processing that maintains accuracy while dramatically reducing time consumption.
Solution Approach 2:
The patent performs preliminary format conversion before the actual wire harness design process begins. By pre-processing the wiring information into a standardized format, the system eliminates the need for time-consuming manual format adjustments during the design phase, thus preserving accuracy while reducing overall design time.
3Adaptability or versatility
If multiple wiring information formats from different sources are integrated, then comprehensive design coverage is achieved, but the difficulty of managing inconsistent formats increases
Solution Approach 1:
The patent creates a universal format conversion capability that can handle multiple wiring information formats from different sources (manufacturers, devices, documentation). The format conversion unit serves multiple functions by adapting to various input formats while outputting to a single standardized format, thus achieving comprehensive coverage without increasing management complexity.
