Segmented Elastic Wrap Design for Stable Cold-Weather Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor protective clothing is ineffective in cold weather, cumbersome for transport, and lacks comprehensive protection from elements like rain and snow, with ponchos offering limited coverage and wraps falling off during movement.
Innovation Solution
A portable, insulative protective device with elastic members that forms a sealed tubular structure around the body, using a combination of breathable and waterproof materials to minimize convective heat loss, with adjustable fasteners for secure fit and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wrap is used for cold weather protection, then warmth is provided, but it falls off when the wearer is standing up or moving
Solution Approach 1:
The wrap is divided into multiple sections with independent fastening mechanisms at different locations (waist, knees, ankles). This segmentation allows the wrap to maintain stability through multiple attachment points while still permitting localized movement at each segment, resolving the contradiction between overall stability and movement freedom.
Solution Approach 2:
The wrap incorporates adjustable fasteners that can be dynamically configured to provide different levels of security and movement freedom. The elastic members provide dynamic adaptation to body movements, maintaining stability during movement while allowing the wearer to adjust the degree of constraint as needed.
2Reliability
If a poncho is used for protection, then it stays in place, but it offers limited protection and is relatively ineffective
Solution Approach 1:
The protective device is segmented into multiple coverage zones (torso, legs, arms) with independent fastening at each zone. This allows comprehensive protection across all body surfaces while maintaining stability through distributed attachment points, overcoming the limited protection of single-piece ponchos.
Solution Approach 2:
The device combines insulative pliable sheet material with elastic members and fastening structures to create a composite system that provides both thermal protection and mechanical stability, enhancing overall protection effectiveness beyond simple poncho designs.
3Reliability
If wraps are tightened around the body to prevent falling off, then stability is improved, but freedom of movement is reduced
Solution Approach 1:
By dividing the wrap into segments with independent fasteners, the system allows selective tightening at different body locations. This enables stability where needed while preserving movement freedom in other areas, resolving the trade-off between overall stability and movement adaptability.
Solution Approach 2:
The elastic members provide dynamic tension that adapts to body movements, maintaining stability during activity without requiring constant tight constriction. The fasteners can be dynamically adjusted to match the wearer's movement needs, preserving adaptability while ensuring reliability.

AI summary
A protective device for maintaining body temperature in a living being is provided. The inventive protective device comprises a first sheet member having a left portion and a right portion. The first sheet member has a left edge and a right edge. A first channel member defines structure defining a first channel. The first channel member defines structure which is secured to and overlies a first portion of the left portion of the first sheet member and overlies a first portion of the right portion of the first sheet member. A second channel defining structure defines a second channel, the second channel defining structure secured to and overlying a second portion of the left portion of the first sheet member and overlying a second portion of the right portion of the first sheet member. Each of the channels have a first side and an opposite side opposite the first side. A variable length member is disposed on and extends along the length of each of the channels. There is a connection structure positioned proximate the left edge; and a mating connection structure positioned proximate the right edge.
