Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging systems for multi-component materials, particularly in dental and medical applications, face issues with cross-contamination, complex handling, evaporation of volatile components, and inaccurate dosing, leading to suboptimal adhesive quality and increased risk of contamination.
Innovation Solution
A one-way packaging system with a rigid housing separated by media-tight foils into at least two areas for storing and mixing multi-component materials, allowing precise dosing and intensive mixing without risk of contamination, using a disposable system that maintains purity and prevents evaporation until use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If multi-component materials are stored in separate bottles for later mixing, then the materials can be stored for extended periods, but cross-contamination risk increases and handling becomes complex
Solution Approach 1:
The packaging system divides the multi-component material into separate compartments within a single container, each component being isolated until mixing is required. This segmentation allows long-term storage while simplifying handling, as the user only needs to activate one container rather than manage multiple separate bottles.
Solution Approach 2:
Multiple component containers are nested within a single outer packaging structure. The individual component bottles or chambers are housed inside the main container, which provides unified protection and simplifies storage. When needed, the entire nested structure is activated together, ensuring proper mixing ratios and reducing handling complexity.
2Productivity
If storage containers are opened multiple times for dosing, then materials can be accessed repeatedly, but evaporation of volatile components occurs and contamination risk increases
Solution Approach 1:
The correct dosage of each component is pre-measured and sealed in individual containers before use. The packaging system is designed to deliver the exact required amount in a single activation, eliminating the need for repeated opening and closing. This preliminary preparation prevents evaporation and contamination while ensuring accurate dosing.
Solution Approach 2:
The packaging system uses disposable single-use containers that are discarded after one use. Each container is sealed until activation, preventing evaporation and contamination during storage. After the material is dispensed, the entire container is discarded, eliminating any risk of cross-contamination or solvent evaporation from repeated access.
3Manufacturing precision
If precise dosing is required for each component, then adhesive quality is maintained, but the dosing process becomes time-consuming and complex
Solution Approach 1:
The correct dosage of each component is pre-measured during manufacturing and sealed in individual containers. The packaging system is designed so that activation automatically delivers the precise required amount of each component, eliminating the need for manual dosing measurements. This preliminary preparation maintains adhesive quality while significantly reducing the time required at the point of use.
4Reliability
If components are mixed in separate containers, then contamination is prevented, but intensive mixing is difficult to achieve
Solution Approach 1:
The mixing chamber is segmented into separate compartments for each component, with sealed barriers that prevent contamination. When activated, the barriers are broken and components are released into the mixing chamber where they can be intensively mixed. This segmentation maintains contamination prevention while enabling effective mixing in a controlled environment.
