Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If power modules are installed on left and right sides to maintain center of gravity, then balance is improved, but wiring complexity increases and heat dissipation deteriorates
Solution Approach 1:
An adapter board is introduced as an intermediary component between the power module and the main circuit control board. The adapter board includes a circuit board with input and output ports for control wires, and a copper foil layer that provides electromagnetic shielding. This intermediary structure simplifies the wiring arrangement by providing dedicated connection interfaces and routing paths, eliminating the need for complex wire management when power modules are positioned on left and right sides.
2Stability of the object's composition
If power modules are installed on left and right sides to maintain center of gravity, then balance is improved, but heat dissipation deteriorates
Solution Approach 1:
The adapter board serves as a mediator that includes wind guiding structures to direct cooling airflow from the cooling fan toward the power modules. The copper foil layer on the adapter board also acts as a thermal management component by providing electromagnetic shielding while allowing thermal pathways to be optimized for heat dissipation from the power modules.
Solution Approach 2:
The adapter board provides localized wind guiding functionality by structuring the circuit board and copper foil arrangement to direct cooling air flow specifically toward the power modules on the left and right sides. This local quality enhancement ensures that even with distributed power module placement, each module receives adequate cooling airflow for effective heat dissipation.
3Adaptability or versatility
If different length control wires are used to connect power modules, then connection flexibility is improved, but output quality deteriorates and maintenance becomes difficult
Solution Approach 1:
The adapter board with standardized input and output ports serves as an intermediary that provides uniform connection interfaces. Control wires can be connected through the adapter board's ports, which are positioned at equal distances from the main circuit control board. This standardized interface approach maintains connection flexibility while ensuring equal wire lengths for all power modules, thereby preserving output quality and simplifying maintenance.
4Adaptability or versatility
If different length control wires are used to connect power modules, then connection flexibility is improved, but maintenance difficulty increases
Solution Approach 1:
The adapter board provides standardized connection ports that serve as intermediate interfaces between the main circuit control board and power modules. This standardization allows for uniform wire routing and connection procedures, making maintenance and repairs more straightforward compared to dealing with varying wire lengths and custom routing arrangements.
