Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If red light therapy is used at high intensity, then myopia progression control effect is improved, but retinal damage risk and user discomfort increase
Solution Approach 1:
The patent changes the intensity parameter of red light therapy by using ambient light excitation instead of high-intensity artificial sources. The spectral filtering means selectively transmits red light (600-750nm) from ambient light, providing sufficient therapeutic effect while maintaining safe intensity levels and eliminating retinal damage risks associated with high-intensity devices.
Solution Approach 2:
The spectral filtering means acts as an intermediary between ambient light and the user's eye. It selectively transmits only the beneficial red wavelength range (600-750nm) while blocking other wavelengths, thereby delivering controlled red light therapy without the harmful effects of high-intensity direct light sources.
2Reliability
If red light therapy with specific devices and timing protocols is used, then myopia progression control is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The system uses ambient light as its own power source, eliminating the need for external power supplies, batteries, or complex control systems. The spectral filtering means is integrated into eyewear that automatically filters and delivers red light whenever ambient light is present, making the device simple, portable, and easy to use without requiring users to follow timing protocols.
Solution Approach 2:
The spectral filtering means can be integrated into various eyewear types (spectacles, contact lenses, intraocular lenses) and functions automatically with any ambient light source (sunlight, indoor lighting). This universal design eliminates the need for specific power-dependent devices and complex timing protocols while maintaining effective myopia progression control.
3Reliability
If red light therapy with specific timing protocols is used, then myopia progression control is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically activates whenever ambient light is present, requiring no user intervention, timing tracking, or protocol adherence. The spectral filtering means continuously delivers red light therapy as long as the wearer is exposed to ambient light, making it the easiest possible system to use while maintaining consistent therapeutic effect.
Solution Approach 2:
The system provides continuous red light therapy whenever ambient light is available, eliminating interruptions and timing gaps that occur with protocol-based systems. This continuous action simplifies operation for users while ensuring consistent myopia progression control through uninterrupted red light exposure.
