Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor survival gear lacks versatility and durability, failing to provide multiple functional uses in various outdoor and survival situations, such as natural disasters or homeless conditions.
Innovation Solution
A survival sack made from a woven high polymer, waterproof material, specifically a non-laminated radiant foil with a 4 mil thickness, designed to be used as a bivy, survival stretcher, or backpack, with features like an attachable hood, collapsible heating sleeve, and customizable cut lines for creating additional survival tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional mylar-based survival products are used, then the product is lightweight and compact, but the tensile strength and durability are insufficient for reuse and cannibalization
Solution Approach 1:
The patent changes the material parameter from thin mylar to 4 mil thick radiant foil, fundamentally altering the strength characteristics to enable reuse and cannibalization while maintaining survival functionality
Solution Approach 2:
The survival sack is designed to serve multiple functions including sleeping bag, stretcher, and backpack, with the durable material allowing parts to be cut and reused for additional survival tools, achieving versatility through a single robust structure
2Adaptability or versatility
If a multi-functional survival sack is designed, then the versatility increases for various outdoor uses, but the device complexity increases
Solution Approach 1:
The survival sack integrates multiple survival functions into a single structure: sleeping bag with hood, stretcher with pole sleeves, and backpack with shoulder straps, allowing one device to replace multiple separate survival tools
Solution Approach 2:
The sack incorporates distinct functional zones including a hood section, body section, and pole sleeves that can be independently utilized, allowing the structure to be segmented for different survival scenarios without requiring separate devices
3Duration of action of stationary object
If the survival sack is designed for reuse and cannibalization, then the durability increases, but the manufacturing cost increases
Solution Approach 1:
The patent specifies using 4 mil thick radiant foil instead of thinner materials, changing the material parameter to achieve durability and reusability while accepting the associated manufacturing cost increase as necessary for survival applications
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 survival sack provides enhanced durability, versatility, and reuse capabilities, serving as a proactive defense against hypothermia in extreme conditions, while also allowing users to create additional survival materials and tools.
Implementation Method 1
The material is a non-laminated radiant foil having preferably a 4 mil thickness, in particular a vapored aluminum adhered to a polyethylene substrate. The material is configured to preserve and trap heat.

AI summary
A survival sack that is made of a non-laminated, radiant sheeting. In particular the survival sack is made from an aluminum clad polyethylene sheeting. The survival sack preferably has a removable hood that attaches by slits and strips of the sheeting. The survival sack can have cut lines printed or formed in the sack for attaching additional survival devices, such as a tube for providing an air conduit from a vehicle heater vent to the inner part of the sack, or for cutting out of shoe liners, or forming a vest from the sack. The sack preferably has pole sleeves that extend on opposing sides of the sack to allow the sack to be utilized as a stretcher.
