Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual analysis and design of circuit diagrams is performed by designers, then design flexibility and adaptability are maintained, but excessive man-hours are required and human errors increase
Solution Approach 1:
The patent replaces the manual mechanical process of analyzing component relationships and designing circuit diagrams with an automated computer-based system. The system automatically retrieves component codes, queries databases for system logical formulas and circuit diagrams, and generates final circuit diagrams without manual intervention, thereby improving both efficiency and accuracy.
Solution Approach 2:
The system enables self-service automation where the circuit diagram determination apparatus autonomously performs the entire design process. By inputting only component codes, the system automatically determines system codes, retrieves appropriate circuit diagrams from databases, and generates final outputs without requiring continuous human guidance or manual design work.
2Adaptability or versatility
If the number of electronic components and systems increases to meet vehicle electrification demands, then vehicle functionality and performance are improved, but the complexity of electronic circuits increases exponentially
Solution Approach 1:
The patent segments the complex circuit design problem into manageable database queries. The system divides the overall circuit determination into separate database lookups: first querying system logical formulas based on component codes, then querying standard circuit diagrams based on determined system codes. This segmentation allows the system to handle complex multi-component systems by breaking them down into queryable database records.
Solution Approach 2:
The patent creates a universal database-driven system that can handle any combination of electronic components through standardized queries. The system uses universal database structures (component code database, system logical formula database, circuit diagram database) that can accommodate any vehicle configuration, making the system adaptable to different vehicle models and electronic system combinations without requiring custom design procedures.
3Manufacturing precision
If standard circuit diagrams are designed by manually analyzing relationships among thousands of electronic components, then customized circuit solutions can be achieved, but the process requires excessive man-hours and increases human error
Solution Approach 1:
The patent implements preliminary action by pre-organizing all circuit design data into structured databases before the actual design process. The component code database, system logical formula database, and circuit diagram database are prepared in advance with all possible component relationships and corresponding circuit diagrams. When a design is needed, the system simply queries these pre-prepared databases rather than creating circuits from scratch, dramatically reducing design time while maintaining accuracy.
