Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a liquid container is included in the spectroscopic system, then spectral measurement capability is achieved, but device size increases and versatility decreases
Solution Approach 1:
The system is divided into a main body (containing light source, imaging device, and spectroscopy section) and a detachable attachment member (containing the optical path changer). This segmentation allows the measurement functionality to be separated from the fixed structure, enabling the system to be used without the attachment member for non-measurement purposes, thereby improving versatility while maintaining measurement capability when needed.
Solution Approach 2:
The optical path changer is extracted as a separate attachment member that can be attached to or removed from the main body. This extraction eliminates the need for a permanent liquid container structure, allowing the system to function as a compact imaging device when measurement is not required, thus resolving the contradiction between measurement capability and versatility.
2Measurement precision
If a liquid container is included in the spectroscopic system, then spectral measurement capability is achieved, but device size increases
Solution Approach 1:
By segmenting the system into a compact main body and a detachable attachment member, the overall device size is reduced. The main body contains only the essential components (light source, imaging device, spectroscopy section) arranged in a compact configuration, while the attachment member is only added when measurement functionality is required, thus minimizing device volume while maintaining measurement capability.
3Measurement precision
If the system is designed for specific measurement applications, then measurement accuracy is improved, but adaptability to other functions decreases
Solution Approach 1:
The main body is designed with universal components (light source, imaging device, spectroscopy section) that can function both for spectral measurement when the attachment member is attached, and for general imaging purposes when the attachment member is removed. This multi-functionality resolves the contradiction by allowing the system to adapt to different uses without sacrificing measurement accuracy when needed.

AI summary
A spectroscopic system includes a main body including a light source that radiates light to a light transmissive measurement target, an imaging device that captures an image based on transmitted light having passed through the measurement target, and a spectroscopy section that is provided in an optical path between the light source and the imaging device and selectively transmits light that belongs to a specific wavelength region, and an attachment that includes an optical path changer that changes the direction of the optical path of the light outputted from the light source and is so attached to the main body as to form a placement space which is located between the optical path changer and the main body and in which the measurement target is placed.
