Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional displacement detection methods are used in high-precision systems, then measurement precision can be achieved, but device complexity increases and scalability is limited
Solution Approach 1:
The patent combines multiple laser sources with different emission wavelengths into a single integrated system that uses a common pump laser. This merging approach maintains the measurement precision benefits of multiple wavelengths while reducing overall system complexity by sharing the pump laser, control electronics, and detection infrastructure across all wavelength channels.
Solution Approach 2:
The system achieves multi-functionality by using a single pump laser to excite multiple organic laser sources that emit at different wavelengths. This universal platform can detect displacements across multiple spectral ranges simultaneously, eliminating the need for separate detection systems for each wavelength and thereby reducing device complexity while maintaining measurement precision.
2Measurement precision
If multiple laser sources with different wavelengths are used, then measurement precision and tunability improve, but device complexity and difficulty of manufacture increase
Solution Approach 1:
Multiple organic laser sources are integrated into a single device structure that shares common manufacturing processes, substrates, and packaging. This merging approach enables all wavelength sources to be fabricated simultaneously using the same organic semiconductor materials and deposition techniques, significantly easing manufacture while maintaining the measurement precision benefits of multi-wavelength operation.
3Ease of operation
If a single pump laser excites multiple laser sources, then ease of operation and scalability improve, but the requirement for precise wavelength tuning increases device complexity
Solution Approach 1:
The system exploits parameter changes in the organic semiconductor materials themselves to achieve wavelength tuning. By selecting different organic compounds with distinct emission wavelengths or by modifying molecular structures, the laser emission wavelength can be tuned without adding mechanical tuning mechanisms. This approach maintains ease of operation while avoiding the complexity of traditional wavelength tuning devices.
4Area of stationary object
If conventional detection systems are scaled for large physical spaces, then coverage area increases, but system complexity and cost increase significantly
Solution Approach 1:
The multi-wavelength laser system provides a universal measurement platform that can monitor multiple parameters (displacement, vibration, temperature) across large areas using a single integrated system. This universal approach scales efficiently to large physical spaces because the same multi-wavelength platform can be deployed across multiple locations, with all locations sharing the same operational protocols and data processing methods, thereby increasing coverage area without proportionally increasing system complexity.
