Solution Overview
Problem
Conventional spectroscopic measurement devices require complex configurations and larger sizes due to the need for different relative positions of light sources and spectrometers for measuring transmitted and reflected light, and they often require additional light shielding, which complicates the setup and increases size.
Innovation Solution
A spectroscopic measurement device with a modular design featuring interlocking housings for the light source and spectrometer, allowing for adjustable positioning and light shielding without additional components, enabling the light source and spectrometer to be placed at desired relative positions while minimizing the device's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light source and spectrometer are disposed at different relative positions for measuring transmitted and reflected light, then the measurement functionality is improved, but the device complexity increases due to multiple rotating members
Solution Approach 1:
The device is divided into separate functional modules: a light source housing, a spectrometer housing, and a sample holder. Each module can be independently positioned and adjusted, allowing the light source and spectrometer to be disposed at different relative positions for transmitted and reflected light measurements without requiring complex rotating members. The modular design simplifies the overall structure while maintaining measurement versatility.
2Object-affected harmful factors
If the whole device is disposed in a housing with light shielding property, then external light interference is reduced, but the device size increases
Solution Approach 1:
Instead of providing light shielding for the entire device housing, the patent applies light shielding properties locally at specific positions where external light interference is most likely to affect measurements. The light source housing and spectrometer housing are designed with light shielding structures that block external light from entering the optical paths, while maintaining a compact overall device size. This localized approach to light shielding reduces the need for a large fully-enclosed housing.

AI summary
A spectroscopic measurement device emits light to a measurement target and measures the measurement light output from the measurement target in accordance with the light emission. A spectroscopic measurement device includes: a first housing having a light shielding property and configured to house a light source that emits light and having a first opening through which the light emitted from the light source passes; a second housing having a light shielding property and having a second opening through which the measurement light passes and configured to house a spectrometer that receives the measurement light that has passed through the second opening; and a junction configured to join the first housing and the second housing such that relative positions of the first housing and the second housing can be changed.
