An illumination device using ultraviolet light sources to recharge luminescent materials on watch displays, combined with a control system to selectively illuminate and capture images, and a shutter mechanism to manage light entry, ensuring clear visibility and efficient energy recharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a matte white dome is used to eliminate reflections, then image quality is maximized and unwanted reflections are minimized, but the user cannot see their watch when it is placed on the winder
Solution Approach 1:
The patent applies a controllable shutter mechanism that dynamically opens to allow user viewing of the watch and closes during imaging operations to eliminate reflections. This dynamic control resolves the contradiction by providing both user visibility and optimal image quality at different times.
Solution Approach 2:
The system implements periodic action by alternating between open shutter state for user viewing and closed shutter state for imaging. This temporal separation allows the matte white dome to function effectively for reflections elimination during imaging while maintaining user accessibility during viewing periods.
2Use of energy by moving object
If high-intensity LEDs are used to illuminate luminescent material, then energy recharge is maximized, but reflections and optical interference increase
Solution Approach 1:
The patent uses periodic illumination with high-intensity LEDs, activating them only during specific recharge intervals rather than continuously. This periodic action maximizes energy transfer to the luminescent material while minimizing reflection issues by limiting illumination to controlled time windows.
Solution Approach 2:
The system maintains continuous useful action by implementing multiple recharge cycles over time, ensuring the luminescent material is consistently recharged without requiring constant high-intensity illumination that would cause reflections. The cumulative effect of periodic illumination achieves full recharge.
3Measurement precision
If the shutter is closed to prevent light entry during imaging, then reflections are eliminated, but the watch cannot be showcased to customers
Solution Approach 1:
The controllable shutter provides dynamic adaptability by switching between closed state for optical monitoring/imaging and open state for customer demonstration. This allows the same device to fulfill multiple functions: maintaining optimal working condition through imaging and showcasing watches to customers.
Solution Approach 2:
The system achieves multi-functionality by combining the shutter mechanism with the matte white dome and periodic illumination, allowing it to perform both protective imaging (with shutter closed) and demonstrative viewing (with shutter open) within the same device architecture.
