Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming gel compositions with high elasticity, such as those using sodium alginate and calcium chloride aqueous solutions, face challenges in stability and storage due to the need for precise control of mixing conditions and the instability of sodium alginate and calcium chloride over time.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If two aqueous solutions (sodium alginate and calcium chloride) are used to form gel composition, then the ion crosslinking reaction can occur to form gel, but the storage stability deteriorates due to difficulty in long-term stable storage of the components
Solution Approach 1:
The container is divided into multiple separate compartments, each holding different components (sodium alginate solution, calcium chloride solution, and crosslinking agent). This segmentation prevents premature contact between components, allowing long-term stable storage of each component in its own stable environment while enabling gel formation when needed.
Solution Approach 2:
The components are prepared and stored in advance in their respective stable forms within the container. The sodium alginate and calcium chloride are pre-dissolved and stored separately with the crosslinking agent, ready for immediate use without requiring preparation at the time of application, thus maintaining storage stability while ensuring reliable gel formation.
2Manufacturing precision
If two aqueous solutions are mixed to form gel composition, then the gel can be formed, but the manufacturing precision deteriorates due to difficulty in controlling mixing conditions and ratios
Solution Approach 1:
The container segments the gel-forming components into separate compartments with defined volumes. This ensures that when the components are discharged and mixed, they do so in precise, predetermined ratios without requiring manual measurement or control of mixing conditions, thus improving manufacturing precision while simplifying the ease of manufacture.
Solution Approach 2:
The container is designed to automatically discharge the components in the correct ratios through its internal structure and mechanism. The system self-regulates the mixing process without requiring external control of mixing conditions or manual intervention, ensuring consistent gel composition while making the manufacturing process easier.
3Reliability
If sodium alginate and calcium chloride are stored separately, then the components can be stored, but the reliability deteriorates due to inability to maintain stable physical properties over time
Solution Approach 1:
By segmenting the components into separate compartments and using an aerosol-based delivery system, each component can be stored independently in its optimal stability condition for extended periods. The aerosol mechanism ensures that mixing occurs only at the moment of use, maintaining reliable physical properties throughout long-term storage.
Solution Approach 2:
The invention changes the physical state and delivery mechanism from traditional liquid storage to aerosol form. This parameter change allows the components to be stored in a stable, concentrated state and only transformed into the reactive mixed state at the moment of application, ensuring reliable physical properties are maintained throughout long-term storage.
