Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional fat metabolism evaluation using ketone concentration in biological gases or urine is used, then fat metabolism can be measured, but instant evaluation of physical changes from past to present or into the future cannot be provided
Solution Approach 1:
The system performs preliminary actions by acquiring physical data (body weight, body composition) at multiple time points before the evaluation moment, and stores this historical data. When evaluation is needed, the system immediately retrieves and compares this pre-acquired data with current ketone concentration measurements, enabling instant evaluation without waiting for new physical measurements to be taken.
Solution Approach 2:
The system establishes a feedback loop where ketone concentration measurements and physical data are continuously acquired, stored, and compared over time. The evaluation section generates feedback by comparing current measurements with past data, providing users with information about physical changes from past to present and projections into the future, thereby enabling continuous monitoring and immediate evaluation.
2Measurement precision
If conventional fat metabolism evaluation is used, then ketone concentration can be measured, but ongoing physical change evaluation for motivation maintenance cannot be achieved
Solution Approach 1:
The system merges multiple measurement functions into a single integrated evaluation system. It combines ketone concentration measurement with physical data acquisition (body weight, body composition), automatically correlates these measurements over time, and generates comprehensive physical change evaluations. This integration makes the evaluation process easy to operate as users simply need to provide samples and the system automatically performs all measurements, comparisons, and generates motivational feedback.
3Measurement precision
If body weight and body fat changes are tracked, then long-term living practice results can be ascertained, but short-term effort changes cannot be detected
Solution Approach 1:
The system performs preliminary action by continuously acquiring and storing physical data (body weight, body composition) at multiple time points before evaluation is needed. This pre-acquisition of data at high temporal resolution enables the system to immediately detect short-term changes when evaluation is performed, without waiting for long intervals between measurements.
Solution Approach 2:
The system applies dynamics by analyzing physical data at multiple time points and comparing changes over different time scales. It dynamically evaluates both short-term changes (detecting effects of recent diet and exercise efforts) and long-term trends (overall living practice results), providing comprehensive feedback that captures both immediate and cumulative effects of user efforts.
