Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If photobiomodulation is applied with fixed dosage and timing in Exosome and stem cell therapies, then the treatment protocol is simple to implement, but the therapeutic effectiveness is limited due to lack of optimization

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidsystem complexity
Core Design Contradiction:

Solution Approach 1:

The patent implements a feedback control mechanism where detectors monitor tissue activity in real-time and the controller adjusts photobiomodulation parameters (dosage, timing, location) based on the detected signals. This closed-loop system optimizes therapeutic effectiveness by adapting treatment to actual tissue response, resolving the contradiction between simple implementation and therapeutic effectiveness.

Inventive Principle:
Principle #23Feedback

2Reliability

If real-time detection and feedback control are implemented to optimize tissue stimulation, then therapeutic effectiveness is enhanced, but the device complexity and cost increase

Engineering Contradiction:

Solution Approach 1:

The patent employs a multi-functional integrated system where a single controller manages multiple light sources and coordinates multiple detectors, performing both stimulation and monitoring functions. This universal approach reduces overall system complexity compared to separate dedicated systems for each function, while still achieving enhanced therapeutic effectiveness through real-time optimization.

Inventive Principle:

Solution Approach 1:

The patent combines multiple detectors and controllers into an integrated system where components work cooperatively under unified control. The controller coordinates multiple light sources and processes signals from multiple detectors, merging functions to achieve high measurement precision while managing system complexity through integrated architecture rather than separate independent systems.
