Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spectroscopy modules face reliability issues due to potential deviations in the relative positional relationship between the incident slit portion and the diode, affecting the module's performance.
Innovation Solution
The spectroscopy module incorporates a light-transmitting body with a spectroscopic portion for dispersing light and a light detecting element featuring a light passing opening, along with an optical element guiding the light, which prevents positional deviations and ensures secure light guidance by projecting the light-incident edge plane and using a recessed portion with a through hole, and optionally an optical fiber for increased light quantity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the incident slit portion and the diode are attached to the supporting body, then the spectroscopy module can be assembled, but the relative positional relationship between the incident slit portion and the diode may deviate, reducing reliability
Solution Approach 1:
The patent merges the incident slit portion and the light detecting element into a single integrated light detecting element structure. The incident slit portion is formed as an opening in the substrate of the light detecting element itself, eliminating the need for separate attachment and ensuring precise relative positioning between the slit and the detecting portion.
Solution Approach 2:
The patent implements a nested structure where the incident slit portion is embedded within the substrate of the light detecting element. The slit is formed as a through-hole or recessed opening in the substrate, with the light detecting portion positioned directly beneath it, creating a nested configuration that ensures precise alignment.
2Reliability
If the light incident marginal part of the light passing opening blocks light, then the structure is simple, but light guidance is not secure
Solution Approach 1:
The patent extends the light guiding function into a new dimension by adding an optical element that protrudes from the light detecting element toward the incident light source. This optical element creates a light-guiding passage that extends in the direction of light propagation, allowing light to bypass the blocking marginal parts and reach the light detecting portion securely.
Solution Approach 2:
The patent introduces an optical element as an intermediary between the incident light and the light detecting portion. This optical element acts as a mediator that guides and directs light around obstacles (the blocking marginal parts) to ensure secure light transmission to the detecting element.

AI summary
In the spectroscopy module 1, a light detecting element 4 is provided with a light passing opening 4b through which light made incident into a body portion 2 passes. Therefore, it is possible to prevent deviation of the relative positional relationship between the light passing opening 4b and a light detection portion 4a of the light detecting element 4. Further, an optical element 7, which guides light made incident into the body portion 2, is arranged at the light passing opening 4b. Therefore, light, which is to be made incident into the body portion 2, is not partially blocked at a light incident edge portion of the light passing opening 4b, but light, which is to be made incident into the body portion 2, can be guided securely. Therefore, according to the spectroscopy module 1, it is possible to improve the reliability.
