Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a spectral optical element is fixed to a housing using conventional methods, then the apparatus can be assembled, but the alignment accuracy and miniaturization are compromised
Solution Approach 1:
The housing is divided into a body portion and a cover portion that can be separated. The spectral optical element is fixed to the body portion with high precision during assembly, and the cover portion is then attached to complete the housing. This segmentation allows for precise alignment of the optical element without requiring the entire housing to be complex or difficult to assemble.
2Reliability
If the spectral optical element is pressed against the housing wall, then fixation is achieved, but external forces may affect dispersion capability
Solution Approach 1:
The pressing portion is designed to apply pressure only to specific localized areas of the spectral optical element's mounting surface, not across the entire optical surface. This localized pressing achieves stable fixation while leaving the dispersion surface free from external forces, thereby maintaining the element's dispersion capability and optical performance.
3Volume of moving object
If the apparatus is miniaturized, then compactness is achieved, but the fixation method becomes more difficult to implement
Solution Approach 1:
The pressing portion is integrated directly into the housing structure itself, merging the fixation function with the housing design. This eliminates the need for separate fixation components or complex assembly procedures, making the miniaturized apparatus both compact and easy to manufacture. The housing body and cover are simply assembled together, with the pressing function built-in.

AI summary
A spectral colorimetric apparatus comprises a light source, a spectral element, a light receiving element, a substrate on which the light receiving element is mounted, a housing and a pressing portion. The housing has a first side wall on which the substrate is fixed and a second side wall on which the spectral element is fixed. The pressing portion pinches the spectral element together with the second side wall and presses the spectral element to the second side wall.
