Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single wavelength laser device is used for photobiomodulation therapy, then the device can be simple and cost-effective, but it becomes inadequate for treating a broad range of conditions as diseased tissues adapt to single-target treatment
Solution Approach 1:
The patent combines multiple laser diodes with different wavelengths (e.g., 808nm, 904nm, 980nm, 1064nm, 1319nm, 1550nm) into a single integrated device. This merging approach allows the device to target multiple molecular pathways simultaneously, addressing the adaptability problem while consolidating what would otherwise require multiple separate devices
Solution Approach 2:
The device is designed as a universal photobiomodulation system capable of treating diverse conditions including cancer, neurological disorders, cardiovascular diseases, and metabolic conditions. The controller enables selective activation of different wavelength combinations to address various disease types and stages, making the device adaptable to multiple treatment scenarios
2Reliability
If multiple separate devices are used to treat different conditions, then each device can be optimized for its specific condition, but the treatment regimen becomes costly and cumbersome
Solution Approach 1:
The device provides condition-specific treatment optimization through pre-programmed protocols for different disease types (cancer, neurological, cardiovascular, metabolic). The controller automatically selects appropriate wavelength combinations and power settings, maintaining treatment reliability while eliminating the need for operators to manage multiple separate devices
Solution Approach 2:
The device incorporates dynamic adaptability through the controller, which can adjust wavelength selection, power levels, and pulse parameters based on the specific treatment protocol and tissue response. This dynamic control allows optimization for different conditions while maintaining a single unified device interface
3Adaptability or versatility
If laser devices operate at continuous power levels, then the treatment process is simple, but the coupling of signal and receptor characteristics cannot be optimized for varying biological conditions
Solution Approach 1:
The device employs pulsed laser operation with variable pulse widths (microsecond to second range) and frequencies (Hz to kHz) rather than continuous operation. This periodic action allows optimization of signal-receptor coupling by delivering energy in controlled bursts that match biological response times, while the controller manages the complexity of timing parameters
4Ease of manufacture
If a device is designed for a specific wavelength range, then the device construction is straightforward, but it becomes limited to treating only a subset of conditions
Solution Approach 1:
The device merges multiple laser diode modules with different wavelength capabilities into a single integrated system. Each wavelength module can be independently manufactured and tested, simplifying the construction process while the combined system provides broad spectral coverage for treating diverse conditions including photoreceptor-targeted visible wavelengths and deeper-penetrating infrared wavelengths
