Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat-dissipating fan unit is fixedly connected to the transformer, then heat dissipation function is ensured, but the power supply device becomes bulky and occupies large space
Solution Approach 1:
The heat-dissipating fan unit is connected to the transformer via a pivotal connection instead of fixed connection, allowing it to rotate between a working position (extending outward for heat dissipation) and a folded position (lying on the transformer surface for compact storage). This dynamic structure enables the device to adapt its configuration based on operational needs.
Solution Approach 2:
The heat-dissipating fan unit is designed as a separable, movable component that can be independently positioned relative to the transformer body. This segmentation allows the fan unit to function effectively when needed while being folded away when not in use, reducing the overall volume of the power supply device.
2Temperature
If a heat-dissipating fan unit is fixedly connected to the transformer, then heat dissipation function is ensured, but the device becomes inconvenient for carrying
Solution Approach 1:
The pivotal connection enables the heat-dissipating fan unit to be folded onto the transformer surface during carrying, transforming the device into a compact form that is easy to transport. When heat dissipation is needed, the fan unit can be rotated to its working position, providing dynamic adaptability for both portability and functionality.
3Volume of stationary object
If the heat-dissipating fan unit is made foldable, then space occupation is reduced, but the structural complexity increases
Solution Approach 1:
A pivotal connection is used to enable the foldable function of the heat-dissipating fan unit. This simple rotational joint allows the fan unit to move between folded and extended positions without requiring complex mechanisms, achieving space reduction while maintaining relatively simple structure.
