Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional greenhouses are used in arid regions, then plant protection from heat is achieved, but water consumption increases significantly
Solution Approach 1:
Instead of using transparent greenhouses that trap heat, the invention uses an open valley structure with reflective surfaces that actively reject solar radiation. The cooling system introduces cool air from higher elevations down into the valley, inverting the traditional greenhouse approach of trapping and heating air inside an enclosed space.
Solution Approach 2:
The patent introduces an intermediary cooling system that uses evaporative cooling towers and air movement mechanisms to transfer cool air from upper valleys into the lower valley areas. This intermediary system mediates between the hot external environment and the plants, providing cooling without requiring direct water application to the plants themselves.
2Temperature
If evaporative cooling systems are used in greenhouses, then temperature control is improved, but water consumption for cooling increases
Solution Approach 1:
The cooling system serves multiple functions simultaneously: it cools the air for plant protection, collects leachate from irrigation for reuse, and manages water resources sustainably. The evaporative cooling towers process both air cooling and water recycling, making the system multi-functional and reducing overall water consumption.
Solution Approach 2:
The system recovers leachate (drainage water) from the valley floors and uses it in evaporative cooling towers. Instead of discarding this water as waste, it is recovered and reused for cooling purposes, significantly reducing the need for fresh water and improving overall water efficiency.
3Area of stationary object
If bauxite residue is disposed of in traditional ways, then land use is minimized, but environmental harm increases
Solution Approach 1:
The invention converts the harmful bauxite residue into a beneficial filling material for the valley structure. The residue, which would otherwise be environmental waste, is used to fill the valley floors and slopes, providing structural support while creating a habitat for plants and animals. This transforms an environmental harm into an environmental benefit.
Solution Approach 2:
The patent merges the waste disposal function with the landscape creation function. The bauxite residue filling is integrated into the valley structure itself, combining the previously separate functions of waste disposal and landform creation into a single unified system that achieves both objectives simultaneously.
4Area of stationary object
If transparent domes are used for recreational greenery, then green space is provided, but energy consumption for cooling increases
Solution Approach 1:
Instead of using transparent domes that trap heat and require active cooling, the invention uses an open valley structure with reflective surfaces that passively reject solar radiation. The cooling is achieved through natural air movement and evaporative cooling rather than energy-intensive air conditioning systems.
Solution Approach 2:
The valley structure provides its own cooling through natural processes: evaporative cooling towers, air movement from higher elevations, and reflective surfaces that reduce solar heat gain. This self-service cooling mechanism eliminates the need for energy-intensive external air conditioning systems.

AI summary
There is disclosed an artificial valley and a method for maintaining a cool microclimate for agricultural, recreational, and residential purposes. It features a symmetrical or asymmetrical landform of a valley with terraced inner slopes, covered with a shading roof made of parallel reflective panels. The terraces and the base of the valley are covered with a layer of soil which may be used for cultivation of plants, as well as recreational or residential purposes involving irrigation. Inner vertical walls are equipped with light-reflecting surfaces for diffusing light onto the terraces. A cooling system maintains a temperature gradient by injecting fresh, cool air at the base of the valley. The cooling system includes a cooling tower with forced ventilation for evaporative cooling of leachate from the terraces, which is then sprinkled on the injected air. Waste material like bauxite residue may be used as a filling material for the valley.
