Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spectrometer designs face issues with electrical junction damage and positional instability between the light detection element and the dispersive part due to external forces, leading to compromised connections and alignment.
Innovation Solution
The spectrometer incorporates a lead pin penetrating through a stem with a projection from the support, ensuring secure electrical connections and stabilizing the positional relationship between the dispersive and light detection elements by routing wiring through projections and securing the support onto the stem.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flexible printed board is used to connect the light detection element to external wiring, then electrical connection is achieved, but external forces can damage the electrical junctions or cause package warping that disrupts the positional relationship between the dispersive part and the light detection element
Solution Approach 1:
The support is divided into a body portion and a projection portion. The projection serves as a dedicated mounting structure that interfaces with the stem, separating the electrical connection function (handled by the lead pin and terminal) from the positional stabilization function (handled by the projection-stem interface). This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The projection acts as a rigid, fixed structural element that replaces the flexible printed board in critical positioning and electrical connection roles. By using a simple protruding structure integrated into the support rather than a flexible board, the design eliminates the vulnerability to external forces while maintaining electrical connectivity through the lead pin and terminal arrangement.
2Stability of the object's composition
If the support is rigidly fixed to stabilize the positional relationship, then alignment between dispersive part and light detection element is maintained, but electrical connection between light detection element and external wiring becomes vulnerable to external forces
Solution Approach 1:
The support is divided into a body portion and a projection portion. The projection serves as a dedicated mounting structure that interfaces with the stem, separating the electrical connection function (handled by the lead pin and terminal) from the positional stabilization function (handled by the projection-stem interface). This segmentation allows each component to optimize its specific function without compromising the other.
Solution Approach 2:
The lead pin acts as an intermediary element that bridges the electrical connection between the terminal (connected to light detection element) and external wiring. By routing the lead pin through the stem and making it contact the terminal in the projection, the design protects the electrical junction from external forces while maintaining stable electrical connectivity.
3Ease of operation
If the lead pin is connected to the wiring outside the package, then electrical connection is achieved, but external forces can damage the electrical junction between the lead pin and the wiring
Solution Approach 1:
The lead pin is pre-positioned to extend through the stem and make contact with the terminal within the projection before final assembly is complete. This preliminary positioning ensures that the electrical connection is established in a protected environment within the package, shielding the junction from external forces that could cause damage during or after assembly.
Solution Approach 2:
The lead pin acts as an intermediary element that bridges the electrical connection between the terminal (connected to light detection element) and external wiring. By routing the lead pin through the stem and making it contact the terminal in the projection, the design protects the electrical junction from external forces while maintaining stable electrical connectivity.

AI summary
A spectrometer comprises a package having a stem and a cap, an optical unit arranged on the stem, and a lead pin penetrating through the stem. The optical unit has a dispersive part for dispersing and reflecting light entering from a light entrance part of the cap, a light detection element for detecting the light dispersed and reflected by the dispersive part, a support for supporting the light detection element such as to form a space between the dispersive part and the light detection element, a projection projecting from the support, and a wiring electrically connected to the light detection element. The projection is arranged at such a position as to be in contact with the stem. The lead pin is electrically connected to a second terminal part of the wiring arranged in the projection.
