Solution Overview
Problem
Current packaging technologies lack effective methods for maintaining temperature-sensitive products at predetermined temperatures during shipping, requiring improved thermal insulation solutions.
Innovation Solution
The development of an insulated container system using a laminated structure with metal layers and a foam material, where the metal layers are bonded to form a heat-sealed structure, and a vacuum release port is used to create a reduced pressure environment, allowing the container to be collapsible for shipping and re-expandable for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional insulated packaging product is used, then thermal insulation is provided, but the packaging cannot be collapsed for shipping, resulting in high shipping volume and cost
Solution Approach 1:
The packaging product employs a dynamic foam material that can transition between expanded and collapsed states. The foam material is contained within a flexible packaging structure that allows compression for shipping and expansion for use, enabling the same product to serve both shipping efficiency and thermal insulation functions
Solution Approach 2:
The foam material's physical parameters (volume, density) are changed through compression and expansion cycles. During shipping, the foam is compressed to reduce volume; during use, it is expanded to provide thermal insulation. This parameter transformation allows the packaging to adapt between shipping and usage states
2Adaptability or versatility
If a rigid insulated container is used, then thermal insulation is maintained, but the container cannot be collapsed or re-configured, reducing flexibility
Solution Approach 1:
The packaging uses a flexible outer shell and thin film structure that encloses the foam material. This flexible containment allows the packaging to be collapsed and re-configured while still maintaining the foam's thermal insulation properties when expanded, combining adaptability with temperature control
3Reliability
If metal layers are bonded together to form a laminated structure, then heat sealing and insulation are improved, but the fabrication process becomes more complex
Solution Approach 1:
The packaging employs a laminated structure combining metal layers with foam material and flexible films. The metal layers provide heat sealing capability and thermal insulation, while the composite structure integrates multiple materials to achieve both reliable sealing and collapsibility without requiring overly complex fabrication processes
