Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If PBM radiation is emitted to induce a PBM response, then the therapeutic effect is achieved, but a considerable amount of energy is required and significant time is needed to achieve the desired dose level
Solution Approach 1:
The patent applies local quality by directing radiation beams to specific predetermined areas (such as the face) rather than uniformly irradiating the entire body. The radiation control unit adjusts beam direction and pattern to concentrate energy on target areas, making the energy delivery more efficient and localized to where the PBM effect is needed.
Solution Approach 2:
The patent implements dynamics by adaptively adjusting the radiation pattern and beam direction in real-time based on detection unit input. The system dynamically modifies which radiation elements are active and their directional characteristics to optimize energy delivery to the predetermined area, reducing wasted energy.
2Reliability
If PBM radiation is emitted to induce a PBM response, then the therapeutic effect is achieved, but significant time is needed to achieve the desired dose level
Solution Approach 1:
By concentrating radiation energy on specific predetermined areas rather than distributing it uniformly, the patent achieves higher energy density in target zones, which accelerates the accumulation of therapeutic dose levels in those areas.
Solution Approach 2:
The dynamic adjustment of radiation patterns ensures that energy is continuously optimized for delivery to the predetermined area, maintaining maximum effective dose rate and reducing the total time required to achieve therapeutic effects.
3Loss of energy
If the radiation beam is directed towards a predetermined area, then energy efficiency is improved, but the device complexity increases due to beam control mechanisms
Solution Approach 1:
The patent segments the radiation source into multiple independent radiation elements that can be individually controlled. This allows selective activation of only those elements needed to illuminate the predetermined area, reducing overall energy consumption and simplifying the control logic compared to a single complex steering mechanism.
Solution Approach 2:
The system uses dynamic control of individual radiation elements' activation states and directional characteristics to achieve efficient energy delivery. This adaptive approach allows the system to respond to changing conditions while maintaining relatively simple per-element control mechanisms.
