Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermal testing systems fail to accurately test temperature conditions of heat generating components due to interference from other components in the system, leading to inefficient cooling and potential damage or shortened lifespan of components.
Innovation Solution
A thermal testing system that includes a thermal control engine which receives temperature data from multiple heat generating components but operates cooling devices only based on the data from the component being tested, ignoring data from components not under test, allowing for more accurate determination of optimal temperature conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the thermal controller monitors temperature conditions of all heat generating components in the system during thermal testing, then the system operates under actual conditions, but the temperature conditions of components not being tested may drive the cooling devices prematurely, causing inaccurate testing results
Solution Approach 1:
The patent extracts the temperature monitoring function for components not being tested from the active cooling control loop. During thermal testing, the system selectively ignores temperature data from components that are not the test subject, allowing the cooling devices to be driven solely by the temperature conditions of the component under test. This extraction eliminates the interference that would otherwise cause premature cooling activation and inaccurate testing results.
Solution Approach 2:
The patent segments the thermal control system into test-mode operation and normal operation. A thermal control engine is implemented that detects whether thermal testing is in progress and adjusts its behavior accordingly. During testing, it monitors only the target component's temperature while ignoring other components; during normal operation, it resumes monitoring all components. This segmentation allows the system to maintain simplicity during testing while preserving full functionality during normal operation.
2Reliability
If cooling devices are activated based on temperature conditions of components not being tested, then those components receive proper cooling, but the component being tested does not receive proper cooling leading to potential damage or shortened lifespan
Solution Approach 1:
The patent extracts the temperature influence of non-tested components from the cooling control decision-making process. By selectively ignoring temperature data from components not being tested, the system ensures that cooling device activation is driven exclusively by the thermal conditions of the component under test. This prevents premature or unnecessary cooling activation that would waste energy while simultaneously ensuring the tested component receives appropriate cooling when needed.
Solution Approach 2:
The patent implements dynamic behavior in the thermal control engine that adapts to testing versus normal operation modes. The system dynamically adjusts which temperature inputs are considered for cooling control based on the operational context. During thermal testing, it dynamically filters out temperature data from non-tested components; during normal operation, it dynamically includes all component temperatures. This dynamic adaptation optimizes both energy efficiency and component protection.

AI summary
A thermal test system includes first and second heat generating components that include first and second temperature sensors, respectively. A thermal controller is coupled to the first and second temperature sensors and at least one cooling device. The thermal controller receives, from the first temperature sensor during a thermal test, first temperature data that is indicative of heat generated in response to the operation of the first heat generating component, as the first heat generating component and the second heat generating component operate as part of the thermal test. The thermal controller also receives, from each second temperature sensor during the thermal test, second temperature data that is indicative of heat generated in response to the operation of the second heat generating component. The thermal controller then operates the at least one cooling device at a level based on the first temperature data while ignoring the second temperature data.
