Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional circuit breakers are used for high-voltage isolation, then isolation reliability is ensured, but device size becomes bulky and cost increases
Solution Approach 1:
The patent merges the power module with isolating functions by integrating fastening members directly onto the power module housing. This combination eliminates the need for separate bulky circuit breakers while maintaining isolation reliability, as the power module itself becomes the isolating element when disconnected from the shelf.
Solution Approach 2:
The power module is designed to serve multiple functions: it acts as both a power conversion device and an isolating element. By incorporating fastening members that enable secure attachment to the shelf, the power module can perform electrical isolation without requiring additional dedicated isolating equipment, thereby reducing overall device size.
2Reliability
If traditional circuit breakers are used for high-voltage isolation, then isolation reliability is ensured, but device cost increases
Solution Approach 1:
The patent combines the isolating function with the power module, eliminating the need for separate circuit breakers. This integration reduces the total bill of materials and manufacturing cost while maintaining isolation reliability through the secure fastening mechanism and electrical disconnection capability.
Solution Approach 2:
The power module serves dual purposes as both a power device and an isolating element. This multi-functionality reduces the number of components needed in the system, thereby lowering overall device cost while ensuring reliable isolation when the power module is detached from the shelf.
3Reliability
If multiple switching elements are used to isolate multiple circuit loops in high-power systems, then complete isolation is achieved, but system complexity increases
Solution Approach 1:
The power module is designed to handle multiple circuit loops simultaneously through its integrated structure. Each power module can isolate multiple circuits at once, eliminating the need for separate switching elements for each loop, thereby reducing system complexity while ensuring complete isolation.
Solution Approach 2:
The patent merges multiple isolation functions into a single power module unit. By integrating the ability to isolate multiple circuit loops within one module, the system requires fewer discrete components and simpler management, reducing overall system complexity while maintaining complete isolation capability.
4Ease of operation
If remote operation capability is added to isolating elements, then operational convenience is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces manual mechanical operation with automated control systems. The fastening members and connection mechanisms are designed to be actuated by control signals, enabling remote operation without requiring complex manual intervention mechanisms, thereby improving ease of operation with minimal increase in device complexity.
