Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a thermometer is used to measure body temperature of each person individually, then measurement precision is improved, but productivity deteriorates due to inefficiency in measuring multiple people
Solution Approach 1:
The system segments the measurement process by using infrared imaging to capture temperature data of multiple individuals simultaneously, then divides the image into reference areas corresponding to each person. This allows individual temperature measurement precision to be maintained while dramatically improving productivity through parallel processing of multiple subjects.
Solution Approach 2:
The system creates a thermal copy of the scene through infrared imaging, which replicates temperature information of all individuals in the group. This copy can be analyzed to extract temperature data for each person without requiring physical contact or sequential measurement, thus resolving the contradiction between precision and productivity.
2Productivity
If an infrared camera is used to measure body temperature of multiple people, then productivity is improved by measuring many people simultaneously, but ease of operation deteriorates due to difficulty in verifying individual temperatures
Solution Approach 1:
The system merges infrared thermal images with visible light images to create a composite image where temperature information is overlaid on familiar visual references. This combination allows users to easily verify individual temperatures by seeing both the thermal data and the visual identification of each person in the same image, thus improving ease of operation while maintaining productivity.
Solution Approach 2:
The visible light image serves as an intermediary that bridges the gap between infrared temperature data and human visual interpretation. By overlaying temperature information on the visible light image, the system creates an intermediate representation that is both scientifically accurate and intuitively understandable for end users.
3Productivity
If infrared camera images are used for temperature measurement, then productivity is improved, but ease of operation worsens because images are determined by manufacturer and require user adaptation
Solution Approach 1:
The system combines infrared thermal images with visible light images that users are already familiar with. This merging allows the productivity benefits of infrared imaging to be realized while eliminating the learning curve associated with interpreting unfamiliar thermal images, as users can relate temperature data to the familiar visual appearance of the scene.
