Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If measurement is continuously performed, then productivity is improved, but measurement precision deteriorates due to interruptions from electronic device operations
Solution Approach 1:
The controller predicts upcoming high-priority processing events (such as incoming calls or notifications) before they occur and proactively suspends measurement in advance. This preliminary action prevents measurement interruptions and ensures continuous accurate data collection, resolving the contradiction between measurement continuity and accuracy.
2Ease of operation
If vibration is generated for user notification, then ease of operation is improved, but measurement precision deteriorates due to contact pressure changes
Solution Approach 1:
The controller applies preliminary anti-action by suspending measurement before vibration occurs. This prevents the harmful effect of vibration-induced contact pressure changes on measurement accuracy, while still allowing vibration notification to proceed for user convenience.
Solution Approach 2:
The measurement function is temporarily extracted or separated from the vibration notification function. By suspending measurement during vibration events, the patent isolates the harmful interaction between these two functions, allowing vibration to provide user notification without compromising measurement precision.
3Productivity
If measurement is performed during high-priority processing, then productivity is improved, but reliability deteriorates due to interruptions
Solution Approach 1:
The controller uses prediction functionality to identify upcoming high-priority processing events before they occur and suspends measurement in advance. This preliminary action ensures measurement reliability by avoiding interruptions, while maintaining overall productivity through efficient resource management.
