Metallized Fabric Pocket for Electromagnetic Radiation Shielding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current garments with pockets, such as brassieres, do not effectively protect wearers from electromagnetic radiation emitted by electronic devices stored within them, posing health risks, especially for children and young women.
Innovation Solution
The development of garments with pockets lined or made from metallized fabrics, such as silver-plated polyamide-elastomer blends, which provide electromagnetic shielding to prevent or reduce radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pockets are added to garments for storing electronic devices, then storage convenience is improved, but electromagnetic radiation exposure to the wearer increases
Solution Approach 1:
A metallized fabric liner is introduced as an intermediary layer between the electronic device (radiation source) and the wearer's body. This liner acts as a mediator that blocks electromagnetic radiation while allowing the pocket to maintain its storage function, thus resolving the contradiction between storage convenience and radiation protection.
Solution Approach 2:
The pocket is constructed using composite materials, specifically a metallized fabric liner combined with regular fabric. The metallized fabric provides electromagnetic shielding properties while the regular fabric maintains comfort and flexibility, creating a composite structure that simultaneously achieves storage convenience and radiation protection.
2Object-affected harmful factors
If metallized fabric liner is added to the pocket, then electromagnetic radiation shielding is improved, but device complexity increases
Solution Approach 1:
A thin metallized fabric liner is used instead of thick or rigid shielding materials. This thin film approach provides effective electromagnetic radiation shielding while maintaining flexibility and minimizing the addition of structural complexity to the pocket design.
Solution Approach 2:
The metallized fabric liner is constructed as a composite material that integrates shielding functionality into a single fabric layer, rather than requiring separate shielding components. This composite structure simplifies the overall pocket construction while maintaining effective radiation protection.

AI summary
A garment that shields a wearer from electromagnetic radiation may generally have a length of fabric forming the garment. The wearable garment may be virtually any garment such as a brassiere, camisole, shirt, pants, leggings, head wear, footwear, and the like. The garment is preferably made of at least a first fabric and a second fabric, where the first fabric is a non-metallized fabric and the second fabric being a metallized fabric. The metallized fabric, in some embodiments, is a metal plated fabric having one or more electrically conductive metals disposed thereon. The metallized fabric is used to form at least one pocket of the garment. Electronics and other devices can be placed and stored in the metallized pocket thereby shielding the wearer from electromagnetic radiation emitted by the electronic or similarly situated device.
