Removable Copper RF Shielding Plate for Mobile Phones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for reducing electromagnetic RF radiation exposure from mobile phones are either non-adjustable, permanently attached, or not compatible with various phone designs and decorative cases, limiting user choice and effectiveness in deflecting radiation.
Innovation Solution
A removable and non-permanently attached metallic plate, typically made of copper, positioned between the mobile phone and its cover, with a powder coating and clear coat to prevent corrosion, allowing for adjustable placement over the phone's rear surface to deflect RF radiation, and featuring a slip-resistant material for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RF shielding is permanently built into protective cases, then radiation protection is provided, but user choice and adjustability are limited
Solution Approach 1:
The RF shielding function is separated from the protective case into a distinct metallic plate component. This allows the shielding function to be independently applied to various cases without requiring each case to be permanently designed with shielding integrated into it, thus enabling user choice while maintaining protection.
Solution Approach 2:
The metallic plate serves as an intermediary component between the mobile phone and the protective case. It can be placed on different cases to provide RF shielding, acting as a universal mediator that enables protection across various case types without limiting user choice.
2Reliability
If RF shielding is permanently attached to the phone, then radiation deflection is ensured, but ease of operation and adjustability are reduced
Solution Approach 1:
The metallic plate is designed with removable and repositionable attachment mechanisms (such as magnetic or snap-fit connections) that allow users to easily adjust its position on the phone back surface. This dynamic attachment system maintains reliable RF shielding while enabling ease of operation and adjustability for different phone models and user preferences.
3Adaptability or versatility
If decorative cases are used without RF shielding, then user expression and style are enhanced, but radiation protection is compromised
Solution Approach 1:
The RF shielding function is segmented from the decorative case into a separate metallic plate that can be independently applied. This allows users to purchase decorative cases for style expression while the metallic plate provides the necessary radiation protection, combining both aesthetic and protective functions without compromising either.
4Adaptability or versatility
If a universal shielding solution is provided, then compatibility with various phones is improved, but effectiveness for specific antenna locations is reduced
Solution Approach 1:
The metallic plate is designed with a universal base shape that can be applied to various phone models, but users can adjust the plate's position and shape to specifically target the antenna locations on each phone model. This local quality adjustment ensures maximum shielding effectiveness for each specific phone design while maintaining overall compatibility across different models.
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
Enables users to choose any decorative or protective case while effectively reducing RF radiation exposure, as the copper plate effectively attenuates electromagnetic radiation and is transferable between different cases, accommodating various phone designs and user preferences.
