Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mobile devices emit electromagnetic waves that are absorbed by human tissues at higher rates than water, leading to potential health risks such as DNA damage and increased cancer risk, particularly when held in direct contact with the head, causing uneven exposure and 'hot spots' due to skull shape and size variations.

Innovation Solution

Integration of a dielectric layer in the keypad keys of mobile devices with wave reflective characteristics to reduce exposure to radio waves, using materials like ferrite beads or transparent dielectric materials that reflect or diffuse incoming radio waves, thereby shielding the user from non-ionizing radiation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mobile devices are held in direct contact with the head for communication, then communication functionality is improved, but radiation exposure to human tissues increases significantly

Engineering Contradiction:

Improvecommunication functionalityVSAvoidradiation exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A dielectric layer is introduced as an intermediary material between the mobile device antenna and the user's head. This layer acts as a mediator that allows electromagnetic wave transmission for communication while simultaneously reducing the absorption of radio waves by human tissues, thereby resolving the contradiction between maintaining communication functionality and reducing radiation exposure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs composite material structures combining dielectric materials with specific properties (such as ferrite beads or transparent dielectric materials) to create a multi-functional layer that provides both radiation shielding and maintains device functionality. This composite approach enables the device to communicate effectively while protecting the user from excessive radiation exposure.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If opaque shielding materials are used to block radiation, then radiation protection is improved, but device visibility and aesthetics deteriorate

Engineering Contradiction:

Improveradiation protectionVSAvoiddevice visibility

Core Design Contradiction:

Object-affected harmful factorsVSIllumination intensity

Solution Approach 1:

The patent utilizes transparent or translucent dielectric materials that can be applied as coatings or layers on the mobile device. These materials provide radiation shielding functionality while maintaining optical transparency, allowing the device screen and display to remain visible and aesthetically pleasing. This resolves the contradiction between radiation protection and device visibility by changing the optical properties of the shielding material from opaque to transparent.

Inventive Principle:

Principle #32Color changes

3Object-affected harmful factors

If dielectric layers are integrated into keypad keys, then radiation exposure is reduced, but device complexity increases

Engineering Contradiction:

Improveradiation exposureVSAvoiddevice structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The dielectric radiation-shielding layer is merged with the existing keypad structure of the mobile device. Instead of adding a separate, complex shielding system, the patent integrates the dielectric material directly into the keypad keys or as a faceplate layer, combining the radiation protection function with the existing structural components. This reduces overall device complexity while achieving the desired radiation exposure reduction.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method and system for protecting a user from exposure from radio waves emitted from a wireless transmitter include at least a layer of dielectric material to operate on the radio wave through reflection, refraction, diffraction, absorption, polarization and/or scattering of the wave. The characteristics and arrangement of multiple layers of shielding on portions of or all of a face plate may significantly reduce exposure to electromagnetic waves and the deleterious effects associated with over exposure. The shielding can be applied subsequent to manufacture, during manufacture or incorporated into structures which may form the transmitting device.
