Solution Overview

Problem

In wireless communication systems, particularly in scenarios where a single user operates multiple devices, existing technologies face challenges in managing identifiers and preventing the spread of infectious diseases through device contact, especially when different identifiers are assigned to mobile and portable devices, leading to incongruity in communication and potential contagion risks.

Innovation Solution

A wireless communication system that manages a touch parameter to switch between identifiers for mobile and portable devices, allowing the portable device to maintain a common identifier when the user returns to the vehicle, thereby preventing the use of the potentially contaminated mobile device and reducing contagion risks by enabling communication through the portable device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single identifier is used for both mobile and portable devices, then communication convenience is improved, but the risk of infectious disease transmission increases when another user touches the mobile device

Engineering Contradiction:

Improvecommunication convenienceVSAvoidinfectious disease transmission risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system changes the identifier parameter dynamically based on the touch status. When the mobile device is touched by another user, the identifier is switched from a common shared identifier to a dedicated unique identifier, thereby preventing other devices from connecting to the potentially contaminated mobile device while maintaining communication functionality through the portable device with the common identifier

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The identifier management is segmented into two types: common identifier for normal communication and dedicated identifier for contamination prevention. This segmentation allows the system to switch between different identifier modes depending on the situation, resolving the contradiction between communication convenience and infection risk

Inventive Principle:

Principle #1Segmentation

2Object-affected harmful factors

If different identifiers are assigned to mobile and portable devices, then infectious disease transmission is prevented, but communication incongruity occurs between the two devices

Engineering Contradiction:

Improveinfectious disease transmission preventionVSAvoidcommunication consistency

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The identifier assignment is made dynamic rather than static. The mobile device can switch between common and dedicated identifiers based on touch status, while the portable device maintains the common identifier. This dynamic adjustment ensures communication consistency when needed and prevents transmission when necessary

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The common identifier serves multiple functions: it enables communication between mobile and portable devices during normal operation, and it allows the portable device to continue communication when the mobile device uses a dedicated identifier. This multi-functionality resolves the communication incongruity while maintaining transmission prevention

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If the mobile device is used for communication, then communication functionality is maintained, but the portable device cannot be used as a backup when the user returns to the vehicle

Engineering Contradiction:

Improvecommunication functionalityVSAvoiddevice switching flexibility

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary identification of touch status when the portable device approaches the mobile device. Based on this preliminary detection, the mobile device proactively switches to a dedicated identifier before the user needs to use the portable device, ensuring seamless transition and maintaining both communication functionality and device switching flexibility

Inventive Principle:

Principle #10Preliminary action

AI summary

When a mobile wireless terminal device and a portable wireless terminal device perform wireless communication according to a second wireless communication scheme, the portable wireless terminal device receives a touch parameter from the mobile wireless terminal device. When the touch parameter does not indicate “touched”, the mobile wireless terminal device activates wireless communication according to a first wireless communication scheme, and the portable wireless terminal device suspends wireless communication according to the first wireless communication scheme. When the touch parameter indicates “touched”, the mobile wireless terminal device activates wireless communication according to the first wireless communication scheme, and the portable wireless terminal device activates wireless communication according to the first wireless communication scheme.
