Engineering Contradiction Analysis
1Temperature
If the power supply module uses a conventional printed circuit board configuration, then the electrical connection between components is established, but the heat dissipation from electronic switches is insufficient and the module occupies excessive space
Solution Approach 1:
The printed circuit board is divided into three distinct zones (first zone for heating body connection, second zone for electronic switches, third zone for connectors) arranged side by side in transverse direction, allowing optimized heat dissipation and space utilization for each functional area
Solution Approach 2:
The zones are arranged side by side in the transverse direction rather than sequentially along the longitudinal axis, transforming the linear layout into a multi-dimensional configuration that improves heat dissipation while reducing overall module area
2Device complexity
If the power supply module components are distributed in conventional configurations, then electrical connections are established, but the spatial distribution of conductive tracks becomes complex and integration space is excessive
Solution Approach 1:
The printed circuit board is segmented into three functional zones with dedicated connection areas, simplifying the spatial distribution of conductive tracks by grouping connections of the same type within each zone and reducing track routing complexity
Solution Approach 2:
Each zone is optimized for its specific function with localized connection points and track distributions tailored to the requirements of heating body connections, electronic switches, and external connectors, respectively
