Engineering Contradiction Analysis
1Use of energy by moving object
If traditional stationary evaporation devices are used, then the device structure is simple, but the solar energy utilization efficiency is low due to inability to rotate and maximize sunlight irradiation time
Solution Approach 1:
The evaporator is designed to rotate dynamically instead of remaining stationary, allowing it to track the sun's movement and maximize sunlight irradiation time. The rotation driving device enables the evaporator to change its orientation continuously, transforming a static system into a dynamic one that adapts to changing solar positions.
Solution Approach 2:
The patent changes the operational parameters of the evaporator by introducing rotation, which alters the irradiation time parameter from a fixed value to a variable that can be optimized throughout the day. This parameter change enables the system to capture solar energy more effectively across different times of day.
2Productivity
If the evaporator rotates to increase irradiation time, then the solar energy utilization efficiency improves, but the device complexity increases due to the rotation driving device
Solution Approach 1:
The rotation driving device is designed to be self-contained, using a motor that can operate independently without requiring external energy sources or complex control systems. The system serves itself by automatically rotating the evaporator to track the sun, eliminating the need for manual intervention or additional energy input.
Solution Approach 2:
The rotation driving device serves multiple functions: it rotates the evaporator to track the sun, maintains the evaporator's position, and can operate independently as a self-contained unit. This multi-functionality reduces the need for separate components and simplifies the overall system.
3Object-affected harmful factors
If a single driving motor is used without additional energy sources, then the environmental benefits and land savings are achieved, but the rotation capability and solar energy capture efficiency are limited
Solution Approach 1:
The system uses a single driving motor that operates independently without requiring external energy sources such as electricity or fuel. The motor is designed to be self-contained and can rotate the evaporator using minimal energy, making the system environmentally friendly while maintaining operational capability.
Solution Approach 2:
The patent replaces complex mechanical or electrical energy systems with a simpler mechanical rotation system driven by a single motor. This substitution reduces the need for additional energy sources and minimizes environmental impact while maintaining the core function of rotating the evaporator to capture solar energy.

Implementation Method 1
An outer surface of the side wall of the evaporator is coated with a solar heat adsorption coating
Implementation Method 2
The evaporator can be kept rotating through the rotation driving device, so that the irradiation time of the sun to the evaporator is increased, and the work efficiency of solution concentration is increased
