Thermal Image Display Apparatus Automatic Temperature Range Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for displaying thermal images require users to manually adjust the temperature range to detect slight temperature differences, which is cumbersome and troublesome.
Innovation Solution
An image display apparatus that automatically sets temperature limits by calculating an upper and lower limit using temperatures from a surrounding environment and a duct, allowing the temperature distribution to be represented by colors within these limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the temperature range is set wide to include both the diagnosis area and surrounding objects with greatly different temperatures, then the thermal image can display the entire scene, but the user must manually adjust the temperature range to detect slight temperature differences in the diagnosis area
Solution Approach 1:
The system automatically determines the temperature range by detecting the temperature of the diagnosis area and autonomously setting the display range, eliminating the need for manual user adjustment. The control section automatically calculates the temperature range based on the diagnosed object's temperature, allowing the system to serve itself rather than requiring user intervention.
2Measurement precision
If the user manually adjusts the temperature range to detect slight temperature differences, then the display precision can be improved, but the operation becomes troublesome and time-consuming
Solution Approach 1:
The system performs preliminary detection of the diagnosis area's temperature and automatically pre-sets the appropriate temperature range before the user views the thermal image. This preliminary action eliminates the need for users to spend time manually adjusting the range, as the system has already optimized the display parameters based on the detected object's temperature characteristics.
3Ease of operation
If the temperature range is set automatically based on the diagnosis area, then the ease of operation is improved, but the system must accurately distinguish the diagnosis area from surrounding objects
Solution Approach 1:
The system uses feedback from temperature detection to automatically adjust and determine the appropriate temperature range. By continuously monitoring the temperature characteristics of the diagnosis area and using this feedback to set the display range, the system can automatically adapt without requiring complex manual intervention or sophisticated area identification algorithms.
