Backpack collapsible coolers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable coolers are difficult to transport and travel with due to their size and design limitations.
Innovation Solution
A collapsible backpack cooler with a base, collapsible portion, straps for securing to the back, and features like an anti-microbial lining and spigot, allowing transition between expanded and collapsed configurations for reduced volume and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional portable cooler is designed to maintain adequate insulation and structural integrity, then cooling performance is improved, but portability and ease of transport deteriorate due to rigid structure and fixed size
Solution Approach 1:
The cooler body is designed to be collapsible, allowing it to transition between an expanded configuration for optimal cooling performance and a collapsed configuration for compact storage and transport. This dynamic structure resolves the contradiction by enabling the cooler to adapt its form factor based on usage requirements.
Solution Approach 2:
The cooler employs a flexible, collapsible body structure that can be compressed to a fraction of its original volume when not in use. This flexible design maintains adequate insulation properties when expanded while dramatically improving portability when collapsed, directly addressing the contradiction between cooling performance and ease of transport.
2Temperature
If a cooler is designed with sufficient insulation and structural rigidity to maintain temperature, then temperature control is improved, but volume and storage space requirements increase
Solution Approach 1:
The collapsible cooler body allows the volume to be dynamically adjusted between a large expanded state for temperature maintenance and a small collapsed state for storage, resolving the contradiction between temperature control requirements and storage volume constraints.
Solution Approach 2:
The cooler can be collapsed into a compact form that nests within itself or other containers, significantly reducing the storage volume required while maintaining full insulation capability when deployed, thus resolving the volume contradiction.
3Strength
If a cooler is designed as a fixed rigid structure to ensure durability and insulation, then structural integrity is improved, but adaptability to different transport conditions deteriorates
Solution Approach 1:
The cooler's collapsible design provides adaptability to various transport conditions by allowing the user to collapse the cooler to a compact size for easy storage in vehicles, backpacks, or luggage, while maintaining structural integrity when expanded for use.
Solution Approach 2:
The cooler changes its physical parameters (volume, shape, density) by transitioning between expanded and collapsed states, enabling adaptation to different transport conditions while maintaining structural integrity through controlled material deformation rather than rigid constraints.

AI summary
A collapsible backpack cooler includes a base, a collapsible portion, a back portion, and one or more straps configured for use by a user in securing the collapsible backpack cooler to their back. The collapsible backpack cooler is configured to allow the collapsible backpack cooler to transition between an expanded configuration, and a collapsed configuration having a reduced volume as compared to the expanded configuration.
