Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing spectroscopic module design, where bandpass filters are attached to a baffle assembly with beam splitters, results in decreased production efficiency due to the complexity and difficulty in replacing damaged filters without removing the beam splitters, leading to inefficiencies in production.
Innovation Solution
A spectroscopic module design where beam splitters are arranged along one direction and bandpass filters are disposed on the opposite side, supported by a structure with an open support surface, allowing for independent replacement and alignment of bandpass filters without affecting the beam splitters, enhancing production efficiency and positional accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If bandpass filters are attached to a baffle assembly with beam splitters, then the structural integration is improved, but the ease of repair deteriorates because damaged filters require removal of beam splitters for replacement
Solution Approach 1:
The patent divides the support structure into separate components: a baffle assembly that holds beam splitters and a separate support body with an open support surface for bandpass filters. This segmentation allows the filter support function to be独立 from the beam splitter mounting structure, enabling easy filter replacement without touching the beam splitters.
Solution Approach 2:
The patent extracts the filter mounting function from the beam splitter assembly by providing a separate support body with an open support surface. This extraction allows bandpass filters to be mounted and replaced independently, separating the repair operation from the beam splitter component.
2Stability of the object's composition
If bandpass filters are attached to a baffle assembly with beam splitters, then the structural integration is improved, but the productivity deteriorates due to complex replacement procedures
Solution Approach 1:
By segmenting the support structure into a baffle assembly and a separate support body with open support surface, the patent enables independent access to bandpass filters during production and maintenance, eliminating time-consuming procedures of removing beam splitters for filter replacement.
Solution Approach 2:
The open support surface design allows for easy removal and replacement of bandpass filters without damaging or moving other components. Damaged filters can be quickly discarded and replaced without affecting the beam splitters or requiring complex disassembly procedures.
3Stability of the object's composition
If bandpass filters are attached to a baffle assembly, then the structural integration is improved, but the manufacturing precision deteriorates due to difficulty in alignment
Solution Approach 1:
The patent segments the mounting structure to provide a dedicated open support surface on the support body for bandpass filters. This separate mounting interface simplifies alignment procedures and improves manufacturing precision by isolating the filter mounting from the beam splitter assembly.
