Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If grow lights are used to promote turf growth, then growth is improved, but ground temperature rises and temperature control accuracy decreases
Solution Approach 1:
The system uses temperature sensors to continuously monitor ground temperature and feeds this information back to the controller, which adjusts the heating/cooling medium flow to maintain target temperature despite grow light irradiation
Solution Approach 2:
The system changes the temperature parameters of the circulating medium (heating or cooling) dynamically based on real-time temperature measurements and control algorithms to compensate for temperature rises caused by grow lights
2Measurement precision
If temperature adjuster is added to control ground temperature, then temperature control accuracy is improved, but device complexity increases
Solution Approach 1:
The temperature adjuster system serves multiple functions: it heats the ground when cold, cools the ground when overheated by grow lights, and maintains optimal temperature for turf growth under various lighting conditions
Solution Approach 2:
A circulating medium (water or air) acts as an intermediary to transfer heat between the temperature adjuster and the ground, enabling temperature control without direct contact between the adjuster and ground

AI summary
To enable temperature control of a vegetation ground with higher accuracy when growth is performed using grow lights. The above problem is solved by a vegetation ground temperature controlling method in which while irradiating a vegetation ground with light of a grow light 10 from above, a temperature of a ground surface area is controlled by supplying a heating medium to a pipe laid in the vegetation ground in an irradiation area of the grow light 10, wherein the temperature of the ground surface area is determined by heat conduction analysis including weather data including outside air temperature and outside air humidity, and irradiation data of the grow light 10 as boundary conditions, and the heating medium supplied to the pipe is controlled so that an underground temperature of the ground surface area becomes a target ground temperature while thermal conductivity of the ground is taken into consideration.
