Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If optical elements are installed in the optical input portion, then the light receiving function is enhanced, but the optical axis deviation occurs leading to measurement inaccuracy
Solution Approach 1:
The optical input portion is segmented into a through hole for light reception and an assembly structure for optical element installation. This segmentation allows the light receiving function to be separated from the optical element mounting function, enabling accurate positioning through the dedicated assembly structure while maintaining open light reception capability.
Solution Approach 2:
The assembly structure acts as an intermediary component between the optical input portion and the optical element. It provides a precise mounting interface that mediates the connection, ensuring the optical axis of the optical element aligns with the optical path while allowing the optical element to be detachably assembled.
2Measurement precision
If optical elements are accurately installed to maintain optical axis alignment, then measurement precision is improved, but the device complexity increases
Solution Approach 1:
The assembly structure merges multiple functions into a single component: it provides mechanical support for the optical element, ensures optical axis alignment through integrated positioning features, and enables detachable assembly. This merging reduces the need for separate alignment mechanisms and simplifies the overall structure while maintaining measurement precision.
3Manufacturing precision
If a detachable assembly structure is implemented, then the optical element can be accurately positioned, but the device complexity increases
Solution Approach 1:
The assembly structure is designed with universal features that enable it to accommodate different optical elements while maintaining positioning accuracy. The standardized interface and positioning mechanism provide multi-functionality, allowing the same assembly structure to precisely position various types of optical elements without increasing complexity.

AI summary
A spectrometer (100) and an optical input portion (32) thereof are disclosed. The optical input portion (32) comprises an assembly structure (322), and the assembly structure (322) is formed at a hole wall (321) of a through hole (3211) of the optical input portion (32). A light (L1) is incident into a dispersing element (2) of the spectrometer (100) along an optical path (13) after passing through the through hole (3211), and is dispersed by the dispersing element (2). The assembly structure (322) is used to be detachably assembled with an optical element (200). When the optical element (200) is assembled with the assembly structure (322), an optical axis of the optical element (200) is linked to the optical path (13). As a result, the light (L1) passing through the optical element (200) is incident to the dispersing element (2) along the optical axis and the optical path (13).
