Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If contact-based charging is used to charge the biological information monitoring apparatus, then charging efficiency is improved, but interference with biological information measurement occurs
Solution Approach 1:
The patent replaces contact-based mechanical charging with wireless electromagnetic charging. The charging unit uses electromagnetic induction to transfer power without physical contact, eliminating the interference that occurs when charging contacts touch the ear. This substitution maintains charging efficiency while ensuring measurement reliability during biological information monitoring.
2Productivity
If charging is performed during biological information monitoring, then device availability is improved, but data accuracy deteriorates due to charging interference
Solution Approach 1:
The control unit monitors the state of the biological information monitoring apparatus and determines appropriate charging timing. It performs charging during periods when monitoring is not actively occurring or when interference is minimal, thereby maintaining data accuracy while ensuring the device remains available for continuous operation through regular charging cycles.
Solution Approach 2:
The system implements periodic charging intervals rather than continuous charging. The control unit schedules charging operations at specific times when biological information monitoring is suspended or when electromagnetic interference is least likely to affect measurement accuracy, thus balancing device availability with data precision.
3Adaptability or versatility
If contact-based charging components are added to the apparatus, then charging capability is improved, but device complexity increases
Solution Approach 1:
The wireless charging unit integrates multiple functions into a single component: it provides power charging, includes control logic for timing operations, and incorporates electromagnetic shielding capabilities. This multi-functional design adds charging capability without proportionally increasing structural complexity, as the same electromagnetic field mechanism serves both charging and interference mitigation purposes.
