Shielding Apparel for Attenuating Electromagnetic Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparel and hunting blinds do not effectively attenuate or block electromagnetic fields emanating from human bodies, which can be detected by animals, leading to increased detection and reduced success in hunting or observing wildlife.
Innovation Solution
Incorporating electromagnetically shielding fabrics with a continuous system of conductive fibers into clothing and hunting blinds to attenuate electromagnetic fields, thereby reducing the likelihood of animal detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional apparel and hunting blinds are used, then visual and odor concealment are provided, but electromagnetic fields emanating from the handler are not attenuated, leading to increased animal detection
Solution Approach 1:
The patent applies composite materials by combining conductive fibers (such as metal fibers, carbon fibers, or other electrically conductive materials) with conventional textile fibers to create a fabric that provides both mechanical strength and electromagnetic field attenuation. This composite fabric integrates the beneficial properties of different materials to achieve electromagnetic shielding while maintaining the flexibility and comfort required for hunting apparel and blinds
2Object-affected harmful factors
If electromagnetic field attenuation is added to apparel, then animal detection is reduced, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the electromagnetic shielding function with the conventional apparel structure by incorporating conductive fibers directly into the fabric weave during manufacturing. This integration combines multiple functions (concealment, comfort, and electromagnetic attenuation) into a single unified material system, eliminating the need for separate shielding components and reducing overall device complexity
3Reliability
If conductive fibers are incorporated into fabric, then electromagnetic field shielding is achieved, but fabric cost and manufacturing complexity increase
Solution Approach 1:
The patent applies parameter changes by varying the concentration, type, and arrangement of conductive fibers within the fabric to achieve different levels of electromagnetic field attenuation. By adjusting these parameters, the fabric can be optimized for specific hunting conditions and animal species, allowing manufacturers to produce differentiated product lines with varying performance characteristics and price points

Function Achieved in This Case
The use of electromagnetically shielding fabrics in apparel and hunting blinds allows hunters and observers to approach animals more closely without detection, increasing the chances of a successful hunt or observation by reducing the animal's perception of the human's electromagnetic field.

AI summary
Attenuating, while handling an animal, one's own emanated electromagnetic field by wearing apparel that includes an electromagnetically shielding fabric. The shielding fabric comprises a substantially continuous system of conductive fibers combined with non-conductive fabric. Or attenuating, while a handler is handling an animal, the electromagnetic field emanated by the handler, by (i) providing to the handler apparel that includes the electromagnetically shielding fabric, and (ii) instructing the handler to wear it while handling an animal, respectively. The attenuation of the emanated electromagnetic field decreases the likelihood of the animal reacting to the emanated electromagnetic field.
