Solution Overview

Problem

Existing wireless communication systems require users to know the SSID of the access point device on a work machine, making it difficult to establish communication when multiple machines are present, as the SSID does not specify the machine.

Innovation Solution

A wireless communication device that uses a work vehicle identification character string as the network name, allowing easy identification and connection by incorporating the vehicle's unique identification into the network name.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a character string that identifies the access point device itself is set in the SSID, then the access point device can be identified, but the SSID cannot specify the work machine provided with the access point device

Engineering Contradiction:
Improveinformation about work machine identityVSAvoidwireless communication setup complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary mechanism where the wireless communication device acquires work machine identification information from the work machine's identification unit and incorporates it into the network name. This intermediary process bridges the gap between the access point's identity and the work machine's identity, allowing users to connect to the correct work machine without directly configuring complex identification systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the SSID is used for wireless communication setup, then wireless communication can be established, but it is difficult for the user to know which SSID should be selected when there are multiple work machines

Engineering Contradiction:
Improveease of wireless communication setupVSAvoidwork machine identification information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent changes the parameter used in the network name from a generic access point identifier to a work machine-specific identification string. By dynamically generating network names that include work machine identification information (such as machine IDs or model numbers), the system enables users to easily distinguish and select the correct work machine for wireless communication setup.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If a generic access point identification system is used, then the system can be simple, but the user cannot easily identify and connect to the target work machine among multiple machines

Engineering Contradiction:
Improvewireless communication system complexityVSAvoidease of work machine identification
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent implements preliminary action by having the wireless communication device automatically acquire work machine identification information before establishing wireless communication. The device proactively retrieves identification data from the work machine and incorporates it into the network name, so that when users view available networks, they can immediately identify the target work machine without needing to understand complex identification systems or perform additional configuration steps.

Inventive Principle:
Principle #10Preliminary action
