Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional waterproof heat-dissipating devices are used, then heat dissipation function is achieved, but device complexity increases and manufacturing cost increases
Solution Approach 1:
The casing is divided into separate waterproof section and heat-dissipating section. The waterproof section contains sealed electronic components, while the heat-dissipating section has open cavities with inlet/outlet covers that allow air flow but prevent water ingress. This segmentation enables independent optimization of waterproofing and heat dissipation functions.
Solution Approach 2:
The inlet and outlet covers serve multiple functions: they seal the cavities to prevent water entry, allow air passage for heat dissipation, and maintain structural integrity. This multi-functionality reduces the need for additional specialized components, simplifying the overall device structure.
2Temperature
If conventional waterproof heat-dissipating devices are used, then heat dissipation function is achieved, but manufacturing time and cost increase
Solution Approach 1:
The modular segmented design allows different sections to be manufactured independently and assembled together, reducing overall manufacturing time and enabling parallel production processes.
Solution Approach 2:
The multi-functional inlet/outlet covers eliminate the need for separate waterproofing components and heat dissipation structures, reducing part count and simplifying assembly operations, thereby reducing manufacturing time.
3Temperature
If conventional waterproof heat-dissipating devices are used, then heat dissipation function is achieved, but manufacturing cost increases
Solution Approach 1:
The segmented design allows for standardized mass production of individual sections, reducing per-unit manufacturing costs through economies of scale and simplified tooling requirements.
Solution Approach 2:
The multi-functional inlet/outlet covers reduce the total number of parts required, lowering material costs, assembly costs, and inventory requirements, thereby reducing overall manufacturing cost.

Implementation Method 1
a fan (50) is mounted in the casing to dissipate heat out of the casing
Implementation Method 2
The inlet cover and outlet cover respectively seal the inlet cavity and the outlet cavity... to keep the water from flowing in the inlet cavity and the outlet cavity

AI summary
A waterproof casing for a power supply has a lower casing, an upper casing, an inlet cover and an outlet cover. The lower cover contains electronic components. The upper casing is mounted on the opening of the lower casing and has an inlet cavity, at least one inlet, an outlet cavity and at least one outlet. The at least one inlet and outlet are formed through the upper casing and respectively communicate with the inlet cavity and outlet cavity. The inlet cover and outlet cover respectively seal the inlet cavity and the outlet cavity, communicate the inlet cavity and the outlet cavity with the lower casing to allow the air to flow inside the casing and to keep the water from flowing in the inlet cavity and the outlet cavity. Structure of the waterproof casing is simplified, so benefits manufacturing.
