Modular Camping Sleep System with Integrated Padding and Quilt Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable camping sleep systems, such as foam pads and sleeping bags, are bulky and difficult to carry, and even self-inflating pads do not provide sufficient comfort and can be slippery with certain types of sleeping bags.
Innovation Solution
A portable camping sleep system that includes a self-inflating layer, a topper layer made of memory foam, and a sleeping quilt, all interconnected via zippers, allowing for modular connection and disconnection of components for enhanced comfort and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If foam pads and sleeping bags are used together, then comfort is improved, but bulk and weight increase significantly
Solution Approach 1:
The patent combines the sleeping pad and sleeping bag into a single integrated unit, where the insulation layers of the sleeping bag are attached to the sleeping pad. This merging eliminates the need to carry separate bulky items while maintaining both comfort and insulation properties.
Solution Approach 2:
The integrated sleeping system uses composite construction combining different materials - the air-filled chambers of the pad with the insulation layers of the sleeping bag - to achieve both comfort and weight reduction in a single unified structure.
2Volume of moving object
If air-based sleeping pads are used to reduce bulk, then portability is improved, but manual or electric pumps are required which add bulk and weight
Solution Approach 1:
The sleeping pad is designed to be self-inflating using the user's body weight and heat to expand the air chambers. This self-service mechanism eliminates the need for external pumps, reducing both bulk and device complexity while maintaining portability.
3Volume of moving object
If self-inflating pads are used to reduce bulk, then portability is improved, but comfort is insufficient and surfaces are slippery
Solution Approach 1:
The sleeping bag is integrated with the self-inflating pad, adding an extra comfort layer that addresses the insufficiency of the pad alone. The combination provides both the bulk reduction of self-inflating pads and the enhanced comfort of multiple layers.
Solution Approach 2:
The integrated system combines the air-based support structure of self-inflating pads with the textile comfort layers of sleeping bags, creating a composite structure that reduces bulk while maintaining or improving comfort.
4Adaptability or versatility
If multiple separate components are used for sleeping systems, then adaptability is improved, but device complexity increases
Solution Approach 1:
The integrated sleeping system is designed to perform multiple functions - providing both pad and sleeping bag functionality in a single unit. This multi-functionality maintains adaptability while reducing the complexity of managing separate components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides improved comfort and insulation by combining different padding materials and allowing for easy connection and disconnection of components, reducing bulk and weight while maintaining stability on uneven terrain.
Implementation Method 1
self-inflating pads have been developed, which are made from open cell foam. Self-inflating pads include a valve which allows air into the self-inflating pad which occupies the open cells in the foam
Implementation Method 2
a topper layer made of memory foam
