Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the SERS element is exposed without protection, then ease of operation is improved, but the optical function part deteriorates due to physical interference and adhesion of foreign matters
Solution Approach 1:
The device is divided into a container body and a separate cover component. The cover can be removed or opened to provide access to the optical function part when needed, while remaining detached to prevent interference and foreign matter adhesion during storage and transport. This segmentation allows the system to switch between protected and accessible states.
Solution Approach 2:
The cover is extracted as a separate removable component rather than being permanently attached. This extraction enables the cover to serve its protective function during storage while allowing complete access to the optical function part when the cover is removed, resolving the contradiction between protection and accessibility.
2Device complexity
If multiple members are bonded with adhesive to form container space, then device complexity is reduced, but foreign matters such as adhesive components and chipping debris adhere to the optical function part
Solution Approach 1:
The container body and cover are merged into a single integral component through molding, eliminating the need for adhesive bonding between multiple parts. This merging prevents adhesive components and bonding-related chipping debris from contaminating the optical function part, while maintaining structural simplicity.
Solution Approach 2:
The container is formed as an integral structure using molding techniques, creating a composite-like unified body without requiring adhesive materials. This approach eliminates foreign matter contamination from adhesives while maintaining the structural integrity and simplicity of the container space.
3Ease of operation
If the minute metal structure is exposed, then ease of operation is improved, but the optical function part deteriorates due to physical interference
Solution Approach 1:
The container is segmented into a body and a separate cover that can be independently positioned. The cover provides physical protection when closed, while its removability ensures full accessibility for Raman spectroscopy operations, resolving the contradiction between protection and operational access.
Solution Approach 2:
The protective cover is extracted as a removable element, allowing it to provide protection during storage and transport while being completely removable to enable unrestricted access to the minute metal structure for spectroscopic analysis, eliminating physical interference only when protection is not needed.
