Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional photobiomodulation devices are used, then therapeutic light exposure can be provided, but the devices are cumbersome and require active user participation for extended periods
Solution Approach 1:
The patent merges the photobiomodulation light source with everyday objects such as laptops, monitors, and eyeglasses. This integration allows the therapeutic device to become a seamless part of common items already present in users' lives, eliminating the need for separate cumbersome equipment and reducing active user participation requirements.
Solution Approach 2:
The patent creates multi-functional devices that serve both everyday purposes (computing, viewing, vision correction) and photobiomodulation therapy simultaneously. The OLED displays and light sources are designed to provide therapeutic near-infrared light while maintaining their primary functions, allowing users to receive therapy during normal daily activities without additional effort.
2Reliability
If photobiomodulation therapy is delivered using traditional devices, then therapeutic effects can be achieved, but consistent light exposure requires extended active user usage
Solution Approach 1:
The patent enables continuous photobiomodulation therapy delivery by integrating light sources into devices users interact with throughout their daily routines. The therapy is delivered continuously during normal device usage (computing, viewing displays, wearing eyeglasses) rather than requiring dedicated therapy sessions, ensuring consistent light exposure without extending active therapy duration.
Solution Approach 2:
The integrated devices automatically provide photobiomodulation therapy without requiring active user participation or awareness. The light sources operate autonomously during normal device functionality, delivering therapeutic effects passively while users engage in their regular activities, thus ensuring reliable consistent exposure without manual intervention.
3Ease of operation
If OLEDs are integrated into everyday objects for photobiomodulation, then passive exposure during normal use is enabled, but control over wavelength, power density, and timing must be maintained
Solution Approach 1:
The patent incorporates dynamically controllable OLED light sources that can adjust their output characteristics (wavelength, power density, timing) in real-time. The devices include control systems that regulate the photobiomodulation light emission to match therapeutic requirements while maintaining ease of passive user exposure during normal device operation.
Solution Approach 2:
The patent utilizes the ability to change key parameters of the OLED light output including wavelength selection, power density modulation, and timing control. These parameter adjustments are managed through integrated control systems that optimize therapeutic effectiveness while allowing passive user exposure during everyday device usage without requiring user intervention.
