Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If several detectors are used to measure light from individual emitters, then measurement capability is improved, but detector variations cause falsification of measurement results
Solution Approach 1:
The patent combines light from multiple emitters into a single detector by using a light guide with specifically adapted optical elements (apertures or reflectors). This merging approach allows one detector to receive equivalent signals from multiple emitters, eliminating the reliability issues caused by detector variations while maintaining measurement capability.
Solution Approach 2:
The light guide acts as an intermediary component between multiple emitters and the detector. It collects light from individual emitters and guides it to the detector through its core, with optical elements that ensure equivalent signal delivery from each emitter, thereby resolving the contradiction between measurement capability and reliability.
2Reliability
If light from multiple emitters is coupled into one detector, then measurement reliability is improved, but the technical complexity increases
Solution Approach 1:
The light guide serves multiple functions simultaneously: it collects light from multiple emitters, guides the light to the detector, and provides optical coupling through its core. This multi-functionality reduces the need for separate complex optical components while achieving reliable measurement from multiple emitters.
Solution Approach 2:
The patent uses specially adapted optical elements such as apertures or reflectors that create equivalent optical paths from each emitter to the detector. These optical elements act as copies or replicas that ensure each emitter delivers an equivalent signal, simplifying the overall coupling architecture while maintaining reliability.
3Reliability
If specially adapted optical elements are used to couple light from multiple emitters, then measurement reliability is improved, but the adaptability to different numbers of emitters is limited
Solution Approach 1:
The light guide is designed with a segmented or modular optical structure that can accommodate different numbers of emitters. The optical elements within the light guide can be configured to handle varying numbers of light sources, allowing the same basic structure to adapt to different emitter arrangements while maintaining reliable measurement.
Solution Approach 2:
The optical coupling system is designed to be dynamic and adjustable, allowing the light guide to adapt to different numbers of emitters. The optical elements can be reconfigured or the light guide can be positioned to accommodate varying emitter configurations, providing versatility while maintaining measurement reliability.
