Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for preparing a tympanic membrane regenerating agent using a gelatin sponge are inconvenient, requiring manual holding and soaking, which consumes time and effort, hindering practitioners from performing other tasks during the process.
Innovation Solution
A preparation jig and vessel system that includes a medicinal solution support with a holding portion to prevent movement, allowing for efficient soaking of the gelatin sponge from multiple sides, and a cover to prevent contamination and facilitate easy installation and removal of the medicinal solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual holding and soaking of gelatin sponge is used, then the medicinal solution can be absorbed, but the time and effort required increases significantly
Solution Approach 1:
The gelatin sponge is placed in a vessel where it automatically absorbs the medicinal solution through capillary action without requiring manual holding or turning. The vessel design allows the sponge to self-soak from multiple directions, eliminating the need for continuous practitioner intervention and significantly reducing preparation time.
Solution Approach 2:
The vessel is designed with multiple openings and channels that allow the medicinal solution to approach the gelatin sponge from multiple directions simultaneously (top, bottom, sides). This multi-dimensional soaking approach drastically reduces the time required compared to traditional single-direction absorption methods.
2Manufacturing precision
If the gelatin sponge is manually held and turned for uniform absorption, then uniform liquid distribution is achieved, but the operation becomes complex and time-consuming
Solution Approach 1:
The vessel is segmented into multiple zones with separate openings positioned at different locations (top opening, bottom opening, side openings). Each opening delivers medicinal solution to different regions of the gelatin sponge simultaneously, ensuring uniform absorption without requiring manual manipulation or turning of the sponge.
Solution Approach 2:
The gelatin sponge is pre-positioned in the vessel in a predetermined orientation that optimizes exposure to medicinal solution from all directions. The vessel structure itself performs the uniform distribution function that would otherwise require manual turning and adjustment, simplifying the operation while maintaining precision.
3Ease of operation
If the medicinal solution and gelatin sponge are placed in an open Petri dish, then access is easy, but contamination risk increases
Solution Approach 1:
The vessel is equipped with a flexible cover that can be partially opened or fully closed depending on the preparation stage. During soaking, the cover can be fully closed to prevent contamination while still allowing the medicinal solution to reach the sponge through the designed openings. The flexible nature of the cover maintains ease of access when needed.
Solution Approach 2:
The vessel acts as an intermediary container between the external environment and the gelatin sponge. It provides controlled access points (openings) that allow medicinal solution to enter while blocking contaminants. The cover serves as an additional intermediary layer that can seal the system when contamination prevention is prioritized.
