Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate light source apparatuses are used for normal light and specific light, then spectral control precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the normal light source apparatus and specific light source apparatus into a single integrated light source system, merging their control functions while maintaining separate light emission capabilities. This reduces device complexity by eliminating the need for two completely independent apparatuses while preserving spectral control precision through unified control of both light sources.
Solution Approach 2:
The integrated light source apparatus is designed to perform multiple functions: it can emit both normal light and specific light with different spectra, and can switch between different observation modes (white light, narrow band, fluorescence). This multi-functionality maintains spectral control precision while reducing the overall number of separate devices needed.
2Stability of the object's composition
If communication is enabled between light source apparatuses, then light amount balance is improved, but system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the control unit monitors the light amounts from both normal and specific light sources, and adjusts their emission intensities to maintain a predetermined light amount ratio. This feedback control ensures stable light amount balance for high-quality image acquisition while using standard communication protocols to minimize system complexity.
3Manufacturing precision
If light intensity control is enhanced, then image quality is improved, but control complexity increases
Solution Approach 1:
The patent controls light intensity by adjusting emission parameters of both normal and specific light sources to maintain a predetermined light amount ratio. The control unit modifies operational parameters (intensity, timing) of light-emitting components based on observation mode requirements, achieving high image quality while managing control complexity through parameter optimization rather than complex mechanical adjustments.

AI summary
A light source system includes a normal light source apparatus provided with a light source controller and a light source apparatus for specific light provided with a specific light controller. In a state where communication is enabled, the light source controller adjusts an emission intensity of the normal light, generates a light amount control signal that makes the normal light and the specific light have a predetermined light amount ratio, and sends the light amount control signal to the light source apparatus for specific light. The specific light controller adjusts an emission intensity of the specific light based on the received light amount control signal.
