Combination Bag and Tarp with Drain Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backpack and shelter combinations do not efficiently utilize space, fail to compact fabric minimally for transport, and prioritize rigidity over comfort.
Innovation Solution
A system comprising a durable, UV-resistant, fire-resistant textile that can be used as a tarp or hammock, which can be folded and rolled into a bag mode, featuring a drain fitting, handles, insulated pockets, and adjustable straps, allowing for compact storage and easy conversion between usage and storage positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional backpack and shelter combinations use a rigid frame structure, then structural stability is improved, but space utilization and compactness for transport deteriorate
Solution Approach 1:
The patent replaces rigid frame structures with flexible textile materials that can be folded and rolled into compact configurations. The textile body serves both as shelter and backpack, eliminating the need for rigid supporting frames while maintaining structural integrity through the flexibility and foldability of the textile material itself.
2Strength
If conventional combinations prioritize rigid frame structures, then structural support is improved, but comfort and minimal compaction for transport deteriorate
Solution Approach 1:
The patent changes the structural parameters from rigid to flexible by using textile materials that can be configured in different states. The textile can be spread out for shelter use providing adequate support, then folded and rolled for comfortable transport. The material properties and configuration parameters are optimized to provide both structural support when needed and comfort during transport.
3Ease of manufacture
If conventional combinations do not maximize fabric space utilization, then manufacturing simplicity is improved, but transport efficiency deteriorates
Solution Approach 1:
The patent makes the textile body serve multiple functions: it acts as both the shelter structure and the backpack container. The same textile material that provides shelter when spread out becomes the backpack when folded and rolled, maximizing the utilization of fabric space without requiring separate components for each function.
4Ease of operation
If conventional combinations do not compact fabric minimally, then ease of conversion between modes is improved, but storage volume increases
Solution Approach 1:
The patent divides the textile body into predetermined sections with fold lines and roll lines that guide the folding and rolling process. This segmentation allows the textile to be systematically folded and rolled into a compact cylindrical backpack shape, minimizing storage volume while maintaining ease of conversion through intuitive foldable structures.

AI summary
A bag and tarp combination that can be moved from a usage position to a storage position by folding the fabric along a first axis, folding the fabric along a second axis, rolling portions the fabric in a first direction along a third axis, and rolling portions of the fabric in a second direction along the third axis.
