Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If intermittent measurement is performed to reduce power consumption, then power consumption is reduced, but detection speed of hypoglycemia is delayed
Solution Approach 1:
The patent applies dynamics by making the measurement interval variable rather than fixed. The control unit dynamically adjusts the measurement interval based on predicted blood sugar level changes, reducing the interval when rapid changes are anticipated and extending it when stability is predicted, thus optimizing both power consumption and detection speed
Solution Approach 2:
The patent applies preliminary action by using a predicting unit to forecast future blood sugar levels based on past measurement data before actual measurement occurs. This prediction allows the system to proactively determine optimal measurement intervals in advance, preparing the measurement schedule ahead of time to balance power consumption and hypoglycemia detection capability
2Loss of time
If measurement interval is shortened for quick detection of hypoglycemia, then detection speed is improved, but power consumption reduction is not achieved
Solution Approach 1:
The patent applies parameter changes by modifying the measurement interval parameter based on predicted blood sugar behavior. When the predicting unit indicates stable blood sugar levels, the system extends the measurement interval to reduce power consumption. When rapid changes are predicted, the interval is shortened to maintain detection speed, thus optimizing the parameter dynamically

AI summary
In a blood sugar level measuring device, a blood-sugar-level predicting unit predicts a blood sugar level of a user. A light emitting unit irradiates measurement light to the inside of a living organism of the user. A light-emission control unit, a measurement-point-candidate setting unit, a light-amount-control-method determining unit, and a measurement-point selecting unit control a light amount of measurement light per one measurement on the basis of the predicted blood sugar level. A light-reception control unit, a light-absorption-spectrum generating unit, and a blood-sugar-value calculating unit receive reflected light from the user and measure a blood sugar level.
