Insulated bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Packaging perishable or temperature-sensitive items poses challenges due to spoilage, destabilization, freezing, melting, or evaporation when temperature is not maintained, and existing insulated packages are often bulky, difficult to store, and not recyclable, leading to environmental issues.
Innovation Solution
An insulated bag assembly comprising a pair of opposing main panels defined in an insulated blank with an insulation batt encapsulated between two sheets, a border extending around the perimeter to form a sealed cavity, and an insulated panel that can be folded and assembled to create a sealed bag, allowing for temperature control and recyclable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional insulated packages are used to maintain temperature, then temperature control is achieved, but the packages become bulky and difficult to store
Solution Approach 1:
The insulated package is divided into separate components: an insulated bag with insulation batt and sheets, and a separate insulated panel. These segments can be stored independently in a compact state and assembled when needed, reducing storage volume while maintaining temperature control functionality.
Solution Approach 2:
The insulated panel is designed to be movable and reconfigurable, allowing it to be stored in a compact form and dynamically assembled into the bag cavity to provide insulation. This dynamic configuration enables the package to transition between compact storage and functional states.
2Temperature
If traditional insulated packages are used for temperature maintenance, then temperature control is achieved, but the packages cannot be recycled and are disposed of in landfills
Solution Approach 1:
The insulated package components, particularly the insulated panel and bag, are designed to be reusable and recyclable. After use, the components can be recovered, disassembled, and reused for subsequent shipments, eliminating the need for disposable insulated packaging and reducing landfill waste.
3Temperature
If insulated panels are positioned within the bag cavity to form a seal, then temperature control and protection are improved, but the device complexity increases
Solution Approach 1:
The insulated panel is pre-formed with the correct shape and size to fit the bag cavity. The insulation batt is pre-encapsulated between sheets with borders that extend around the perimeter. These preliminary preparations simplify the assembly process, as the components are ready to be inserted and sealed without requiring complex on-site fabrication or adjustment.
