Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical connection unit and series-parallel switching unit are installed separately, then each unit can be designed independently, but the overall apparatus size increases and wiring complexity increases
Solution Approach 1:
The patent combines the electrical connection unit and series-parallel switching unit into a single integrated power control apparatus. The housing contains both units, and the control unit coordinates their operations, eliminating the need for separate apparatuses and reducing overall space requirements while maintaining independent functionality of each unit.
2Ease of manufacture
If electrical connection unit and series-parallel switching unit are installed separately, then each unit can be designed independently, but the number of wiring connections and assembly time increases
Solution Approach 1:
The patent integrates both units within a single housing structure, reducing the number of separate assembly operations. The control unit manages both the electrical connection and series-parallel switching functions centrally, simplifying the assembly process and reducing the time required to install and wire multiple separate apparatuses.
3Adaptability or versatility
If separate wiring connections are used between electrical connection unit and series-parallel switching unit, then flexibility in installation is improved, but the complexity of wiring and potential for incorrect assembly increases
Solution Approach 1:
The patent consolidates the wiring connections within the integrated housing, eliminating external wiring between separate units. The control unit provides centralized management of electrical connections and switching operations, reducing wiring complexity and minimizing the risk of incorrect assembly while maintaining installation flexibility through the unified design.
