VSEngineering Contradiction Analysis

1Productivity

If a traditional spectrometer uses a single signal receiver for wavelength detection, then the device structure is simple, but wavelength switching requires multiple optical fiber plugging and unplugging operations which complicates the operation process and reduces measurement efficiency

Engineering Contradiction:

Solution Approach 1:

The patent divides the signal reception function into multiple parallel signal receivers, each dedicated to receiving spectral signals at specific wavelengths. This segmentation eliminates the need for manual switching and plugging/unplugging of optical fibers, as each receiver continuously monitors its assigned wavelength range, thereby improving measurement efficiency while maintaining operational simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a multi-functional detection system where multiple signal receivers simultaneously perform wavelength detection across different spectral ranges. This multi-functionality allows the system to handle multiple wavelengths concurrently without requiring operational changes, resolving the contradiction between improved productivity and device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
