Packaged Drug Container Dual Oxygen Scavenger System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medicine-filled containers do not effectively remove oxygen quickly and continuously, which can lead to medicine degradation, as they rely on passive oxygen scavenging methods that are not sufficient for maintaining a low-oxygen environment over time.
Innovation Solution
A packaged medicine-filled container with a resin-made container and a sealed, hardly oxygen-permeable packaging body that incorporates both moisture-dependent and self-reacting type oxygen scavengers to rapidly remove oxygen initially and maintain a low-oxygen atmosphere through continuous scavenging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single type of oxygen scavenger is used in the packaging body, then the structure is simple, but oxygen cannot be removed quickly and continuously
Solution Approach 1:
The patent combines two different types of oxygen scavengers (moisture-dependent type and self-reacting type) into a single packaging system. The moisture-dependent type oxygen scavenger quickly removes oxygen in the early period by reacting with moisture and oxygen, while the self-reacting type oxygen scavenger continuously removes oxygen over time. This merging of different scavenging mechanisms resolves the contradiction by achieving both quick initial oxygen removal and continuous long-term oxygen removal without requiring complex separate systems.
Solution Approach 2:
The moisture-dependent type oxygen scavenger performs preliminary action by quickly removing oxygen in the early period of storage. This initial rapid oxygen removal creates a low-oxygen environment quickly, which is then maintained by the self-reacting type oxygen scavenger. This preliminary action principle allows the system to achieve fast oxygen removal initially while maintaining simplicity through the coordinated action of both scavenger types.
2Speed
If passive oxygen scavenging is used, then the packaging structure is simple, but oxygen removal speed is insufficient for medicine stabilization
Solution Approach 1:
The patent merges two oxygen scavenging mechanisms with different operational characteristics: the moisture-dependent type provides fast initial oxygen removal speed, while the self-reacting type ensures reliable continuous oxygen removal. This combination resolves the contradiction between speed and reliability by leveraging the strengths of both scavenger types - the moisture-dependent type achieves rapid oxygen removal to stabilize medicine quickly, while the self-reacting type maintains reliable low-oxygen conditions over the storage period.
3Stability of the object's composition
If oxygen is not removed quickly in the early period, then the packaging system is simple, but medicine degradation occurs
Solution Approach 1:
The moisture-dependent type oxygen scavenger performs preliminary action by rapidly removing oxygen in the early period of storage. This quick oxygen removal establishes a low-oxygen environment quickly, preventing medicine degradation during the critical initial period. The self-reacting type oxygen scavenger then maintains this stable low-oxygen condition over time. This preliminary action principle resolves the contradiction by achieving both fast time to low-oxygen state and long-term medicine stability.
