Engineering Contradiction Analysis
1Loss of energy
If constant pressure design is used in burn-in test machines, then device simplicity is maintained, but heat dissipation capability is insufficient for high power consumption products
Solution Approach 1:
The patent applies dynamics by transitioning from constant pressure design to dynamic pressure adjustment. The controller continuously modifies the internal pressure of the cabin based on real-time temperature feedback from the target object, enabling the system to adapt to varying heat dissipation requirements during burn-in testing of high-power consumption products.
Solution Approach 2:
The patent implements parameter changes by adjusting the pressure parameter within the cabin to optimize heat dissipation. By changing the internal pressure from a fixed constant value to a dynamically adjusted variable, the system enhances thermal management capability without requiring fundamentally new hardware architecture.
2Reliability
If dynamic pressure adjustment is implemented to improve heat dissipation, then temperature control stability is improved, but system complexity increases
Solution Approach 1:
The patent employs feedback control by using a temperature response structure to continuously monitor the temperature of the target object and feed this information back to the controller. The controller then adjusts the cabin pressure accordingly, creating a closed-loop system that maintains temperature stability while managing heat dissipation for high-power products.

AI summary
A control method is provided and used to place a target object on a test platform in a cabin of a testing device, to sense the temperature of the target object by a temperature response structure, and then to receive temperature signals of the temperature response structure by a controller, where the controller can regulate the pressure inside the cabin to control the air pressure of the cabin, so that the target object can still maintain good heat dissipation under high power consumption.
