Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If skin condition measurement is performed without professional guidance, then ease of operation is improved, but measurement precision deteriorates due to inconsistent contact pressure
Solution Approach 1:
The system provides real-time feedback to users about their contact pressure through visual indicators on the display. The processor receives contact pressure information from the skin contact device and presents this information to the user, enabling them to adjust their pressing force to achieve the optimal measurement pressure. This feedback mechanism allows non-professional users to maintain consistent contact pressure without requiring extensive training.
Solution Approach 2:
The system enables users to self-correct their measurement technique by providing intuitive guidance on the display. The interface automatically detects when proper contact pressure is applied and provides visual confirmation, allowing users to independently achieve accurate measurements without professional intervention or complex instructions.
2Ease of operation
If contact pressure is not maintained constant, then ease of operation is improved, but reliability of skin condition measurement deteriorates
Solution Approach 1:
The system continuously monitors contact pressure and provides real-time visual feedback to users. The display shows whether the user is applying adequate pressure, enabling them to maintain consistent contact pressure throughout the measurement process. This ensures reliable and repeatable measurements while keeping the operation simple for non-professional users.
Solution Approach 2:
The system provides preliminary guidance information before the measurement is taken, instructing users on the appropriate contact pressure level. This pre-instruction, combined with real-time feedback during measurement, ensures that users can maintain consistent pressure without requiring complex technical knowledge.
3Measurement precision
If contact pressure information is provided to users, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The display serves multiple functions: it presents skin condition measurement results, provides contact pressure feedback, and offers measurement guidance. By making the display multi-functional, the system avoids adding separate hardware components for pressure feedback, thereby improving measurement precision without significantly increasing device complexity.
Solution Approach 2:
The communication circuit acts as an intermediary, receiving contact pressure information from the skin contact device and transmitting it to the display for user presentation. This modular approach allows the system to integrate pressure feedback functionality without requiring direct complex wiring between all components, thus maintaining relatively simple device architecture while achieving precise measurements.
