Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed optical power glasses are used for myopia control studies, then the test routine is simple and easy to follow, but the ability to investigate various under-correction schedules is limited
Solution Approach 1:
The patent applies dynamics by transitioning from fixed optical power lenses to variable optical power lenses that can dynamically adjust their corrective power. The optical article includes lenses with optical powers that can be changed over time, allowing different under-correction schedules to be implemented without requiring multiple separate glasses pairs. This enables the investigation of various myopia control protocols while using a single adaptable optical device.
Solution Approach 2:
The patent implements parameter changes by modifying the optical power parameter of the lenses over time according to predetermined schedules. The system can alter the degree of under-correction (e.g., switching between 0.5D, 1.0D, 1.5D under-correction levels) and the timing patterns (e.g., morning/evening schedules, continuous vs. intermittent application) by changing the optical power parameters programmatically, thereby enabling versatile myopia control research.
2Adaptability or versatility
If multiple pairs of fixed optical power glasses are provided for different under-correction conditions, then various under-correction routines can be investigated, but the test routine becomes complicated and troublesome for subjects
Solution Approach 1:
The patent applies universality by designing a single optical article that can perform multiple functions corresponding to different under-correction protocols. Instead of requiring subjects to switch between multiple specialized glasses pairs, the universal optical device can be programmed to implement various under-correction schedules (different degrees, different timing patterns) within a single device, thereby simplifying the test routine while maintaining research versatility.
Solution Approach 2:
The patent implements self-service through automated optical power adjustment mechanisms that eliminate the need for subject intervention in switching lenses. The system automatically transitions between different optical power settings according to predetermined schedules, with features such as automatic time-based switching, wireless communication for protocol updates, and automated calibration, thereby making the complex protocol changes transparent and effortless for the subject.
3Adaptability or versatility
If subjects manually switch between different glasses pairs, then various under-correction schedules can be implemented, but subject compliance and accuracy may be compromised
Solution Approach 1:
The patent applies feedback through automated monitoring and verification systems that track whether the correct optical power settings are being applied at the correct times. The system includes sensors and controllers that monitor lens selection, switching timing, and wear duration, providing real-time feedback to both the subject and researchers. This automated feedback mechanism ensures high compliance and accuracy by objectively verifying protocol adherence without relying on subject self-reporting.
Solution Approach 2:
The patent replaces the manual mechanical system of switching glasses pairs with an automated electromechanical or electronic control system. The automated system uses motors, solenoids, or electronic liquid crystal technology to switch between different optical power lenses based on programmed schedules, eliminating human error and subject compliance issues associated with manual switching. The system autonomously manages the complexity of protocol implementation.
