Solution Overview

Problem

Conventional mobile communication devices position antennas near the user's head, leading to potential tissue damage and health concerns due to radio frequency (RF) energy exposure, particularly affecting the brain and eyes.

Innovation Solution

The design incorporates a separable external antenna system that can be positioned at a spaced distance from the user's head, using a rotatable plate, strap, or retractable mechanism to reduce RF energy interaction with the brain and eyes, allowing the antenna to be placed away from the device when in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the antenna is positioned near the top of the mobile communication device, then the device can maintain compact form factor and ease of operation, but RF radiation enters the user's head including brain and eye tissues causing health concerns

Engineering Contradiction:

Improveease of operationVSAvoidRF radiation exposure to head tissues

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The antenna system is segmented into two parts: an internal antenna integrated into the mobile device and an external antenna that can be separated and positioned away from the user's head. This segmentation allows the device to maintain compact form while providing an option to reduce RF exposure by using the external antenna.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The harmful RF radiation source (external antenna) is extracted from the immediate vicinity of the user's head and positioned at a distance, connected via a cable. This extraction reduces the harmful effect of RF radiation on brain and eye tissues while maintaining communication functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

2Object-affected harmful factors

If the antenna is positioned at a spaced distance from the user's head, then RF energy interaction with brain and eyes is reduced, but the device complexity increases due to additional mechanisms required

Engineering Contradiction:

ImproveRF radiation exposure to head tissuesVSAvoiddevice complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The antenna system provides dynamic configurability, allowing users to switch between internal and external antenna modes based on their needs. The retractable cable mechanism enables dynamic adjustment of the external antenna's position and connection state, balancing RF exposure reduction with device complexity management.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The external antenna can be discarded (removed from the device) when not needed, and the retractable cable automatically recovers into the device housing. This approach reduces complexity by allowing the system to return to a compact state when the external antenna is not in use.

Inventive Principle:

Principle #34Discarding and recovering

3Object-affected harmful factors

If a separable external antenna system is implemented, then RF radiation exposure to user tissues is reduced, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:

ImproveRF radiation exposure to head tissuesVSAvoidease of manufacture

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The mobile device is designed with multi-functionality to accommodate both internal and external antenna configurations. The device can operate with either antenna type, providing universal compatibility and flexibility. This multi-functionality is achieved through standardized connectors and switching mechanisms that can handle both configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

A cable with connectors serves as an intermediary element between the mobile device and the external antenna. This intermediary component simplifies manufacturing by using standard connector technologies and allows the external antenna to be produced separately, reducing the complexity of integrating a permanently attached external antenna system.

Inventive Principle:

Principle #24Intermediary (Mediator)
