Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customized tools are designed for each main board and side board configuration, then the side board can be maintained in a vertical state during wave soldering, but the cost and time significantly increase
Solution Approach 1:
The patent applies universality by designing a standardized auxiliary supporting device with a universal structure that can accommodate different main board and side board configurations. The device includes a supporting plate with positioning structures and a fixing mechanism that can adapt to various board types without requiring customization, thereby maintaining vertical state reliability while reducing device complexity and cost
Solution Approach 2:
The patent applies dynamics by incorporating an adjustable fixing mechanism that can dynamically adapt to different board configurations. The fixing mechanism includes adjustable clamping forces and positioning elements that can be configured based on the specific side board being soldered, allowing the same device to maintain vertical stability across multiple configurations without requiring multiple specialized tools
2Manufacturing precision
If additional customized tools are used to maintain side board vertical state, then soldering quality can be ensured, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-configuring the auxiliary supporting device with standardized positioning structures and fixing mechanisms before the soldering process. The device is designed in advance to accommodate common board configurations, eliminating the need for time-consuming customization during production. The pre-designed structure ensures soldering quality is maintained while reducing setup and tool design time
3Manufacturing precision
If different customized tools are designed for various board configurations, then vertical alignment during soldering can be maintained, but production cost increases
Solution Approach 1:
The patent reduces production cost by designing a universal auxiliary supporting device that can serve multiple board configurations with a single standardized tool. This eliminates the need to manufacture multiple specialized tools for different configurations, thereby maintaining vertical alignment precision while significantly reducing manufacturing costs through economies of scale and simplified production processes

AI summary
A power module and an auxiliary supporting device adapted thereto are provided. The auxiliary supporting device is used to maintain a first circuit board in a vertical state on a second circuit board. The auxiliary supporting device includes a first plate and a second plate. The first plate is parallel to and fixed to the first circuit board. The second plate is extended from the first plate in a direction away from the first circuit board. A bottom edge of the second plate is disposed on a surface of the second circuit board facing the first circuit board. The auxiliary supporting device is universally suitable for different combinations between the first plate and the second plate without the need of customized tool.
