Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional thermometer is used for continuous body temperature measurement, then measurement accuracy can be maintained, but user convenience and ease of operation deteriorate due to the need for prolonged contact with body parts
Solution Approach 1:
The patent implements a disposable electronic thermometer that can be used once and then discarded. This resolves the contradiction by providing a convenient, single-use device that maintains measurement reliability during its operational lifetime without requiring prolonged attachment or complex handling procedures. The disposable nature eliminates hygiene concerns and simplifies continuous monitoring during dynamic tasks.
2Productivity
If a conventional thermometer requires prolonged contact with body parts for measurement, then measurement reliability is improved, but productivity and ease of continuous monitoring deteriorate during dynamic tasks
Solution Approach 1:
The patent creates a dynamic measurement system where the disposable electronic thermometer can be quickly attached and detached from the body. The device performs temperature measurements autonomously over time once attached, eliminating the need for continuous user intervention or prolonged manual contact. This enables continuous monitoring during dynamic tasks while minimizing the time and effort required for measurement operations.
3Reliability
If continuous body temperature monitoring is implemented, then disease detection capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent employs a disposable electronic thermometer with integrated temperature sensing, control circuitry, and wireless communication capabilities. By making the entire device disposable rather than reusable, the system can incorporate more sophisticated monitoring and communication features without increasing long-term complexity management. Each unit remains relatively simple in construction while providing reliable continuous monitoring and disease detection capabilities when needed.
