Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface-enhanced Raman scattering units face damage and optical function part deterioration during transportation due to components in gel packs or tapes, and risk of chipping when mounted on IC chip trays.
Innovation Solution
A surface-enhanced Raman scattering unit with a transportation board and detachable holding part that mechanically secures the SERS element without adhesives, preventing deterioration and damage by pinching the element between the board and holding part, and featuring a depression to restrain the element during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the SERS element is secured using gel packs or tapes during transportation, then the element is protected from damage, but the optical function part deteriorates due to components in the gel pack or tape ingredients
Solution Approach 1:
The patent introduces a transportation board as an intermediary carrier between the SERS element and the external environment. This board provides a clean, inert surface that mechanically supports the element during transport without introducing harmful chemical components, thus protecting both the physical integrity and optical performance of the SERS element.
Solution Approach 2:
The patent replaces chemical bonding methods (adhesives, gel packs) with a mechanical holding system consisting of a holding part with pinching parts. This mechanical system secures the SERS element through physical constraint rather than chemical adhesion, eliminating the deterioration caused by tape or gel components while maintaining protection from damage.
2Strength
If the SERS element is mounted on an IC chip tray with cover, then the element is protected from physical damage, but the element may be chipped due to vibrations during transportation
Solution Approach 1:
The patent implements a depression in the transportation board that is shaped to receive and cradle the SERS element. This pre-formed recessive structure provides cushioning and positional restraint before transportation begins, preventing the element from shifting or contacting hard surfaces during vibration, thus avoiding chipping while maintaining protection.
Solution Approach 2:
The holding part with pinching parts acts as an intermediary mechanical constraint system between the SERS element and the transportation board. This system secures the element in a fixed position within the depression, preventing vibration-induced movement that could cause chipping, while the depression itself provides the primary cushioning interface.
3Ease of operation
If adhesives or tackifiers are used to secure the SERS element, then the element is held in place during transportation, but the optical function part deteriorates due to chemical components
Solution Approach 1:
The patent completely replaces chemical adhesion systems (adhesives, tackifiers, gel packs) with a mechanical holding system. The holding part with pinching parts applies physical constraint forces to secure the SERS element, while the depression provides positional restraint. This mechanical approach achieves secure holding without any chemical contact that could deteriorate the optical function part.
Solution Approach 2:
The transportation board with its depression and the holding part serve as intermediary mechanical structures that provide secure holding functionality without introducing harmful chemical components. These intermediaries transfer and distribute mechanical restraint forces while maintaining a clean interface with the SERS element's optical function part.
