Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are integrated into the ophthalmic system to ensure measurement reliability, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces an external electronic device as an intermediary that performs the complex measurement and control calculations. The ophthalmic system only needs to transmit sensor data and receive control commands, eliminating the need for complex onboard processing while maintaining measurement reliability through data validation against environmental conditions.
Solution Approach 2:
The patent extracts the complex control logic and measurement validation functions from the ophthalmic system and relocates them to an external electronic device. This allows the ophthalmic system to use fewer sensors while achieving the same measurement reliability through external data cross-validation.
2Ease of manufacture
If sensors are poorly positioned relative to light flux, then manufacturing ease is improved, but measurement precision deteriorates
Solution Approach 1:
The external electronic device acts as a mediator that receives data from various sources including ambient light sensors, device orientation sensors, and environmental information. It processes this data to compensate for suboptimal sensor positioning in the ophthalmic system, calculating corrected measurements that account for the actual light flux conditions.
Solution Approach 2:
The system dynamically adjusts control parameters based on environmental conditions detected by the external device, such as light direction, intensity, and spectral composition. This allows the system to optimize lens transmission control even when the onboard sensors are not optimally positioned, by compensating through environmental parameter data.
3Device complexity
If control is based solely on sensor measurements, then device simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The external electronic device serves multiple functions: it collects environmental data, processes sensor measurements, determines appropriate lens transmission control, and communicates commands back to the ophthalmic system. This multi-functional approach allows the ophthalmic system to remain simple while achieving high adaptability through the external device's comprehensive data processing capabilities.
Solution Approach 2:
The system implements a feedback loop where the external electronic device continuously monitors environmental conditions and user behavior, processes this information, and sends adjusted control commands to the ophthalmic system. This feedback mechanism enables the system to adapt to changing conditions without requiring complex onboard processing, maintaining simplicity while achieving versatility.
