Solution Overview
Problem
Existing communication systems for working vehicles face challenges in preventing unauthorized output of electromagnetic waves, particularly when the vehicle is used in areas where the reader is not authorized, leading to potential regulatory compliance issues.
Innovation Solution
A communication system that includes an information receiving unit, a first area information storage, a comparing unit, and a communication control unit to prohibit the output of electromagnetic waves when the vehicle is used in an unauthorized area, ensuring compliance with local regulations by only allowing wave output in permitted areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reader is installed in a working vehicle to read identification information from wireless tags, then the ability to identify replacement parts is improved, but the risk of unauthorized electromagnetic wave output in areas where the reader is not authorized increases
Solution Approach 1:
The system performs preliminary area verification by comparing the current location (obtained via GPS or other positioning means) against authorized operating areas before allowing the reader to output electromagnetic waves. This preventive check ensures the reader only operates in permitted geographical zones, eliminating the harmful effect of unauthorized electromagnetic wave transmission while preserving the part identification function.
Solution Approach 2:
An area verification mechanism acts as an intermediary between the positioning system and the reader. This intermediary layer checks whether the current location falls within authorized areas and only permits electromagnetic wave output when verification succeeds. This mediator structure resolves the contradiction by enabling reliable part identification only when and where authorized.
2Ease of operation
If the reader is authorized for use in a specific area, then electromagnetic wave output is permitted in that area, but the vehicle cannot be used in other areas without causing unauthorized output
Solution Approach 1:
The system dynamically adjusts the reader's operational state based on real-time location data. Rather than using a static authorization model that restricts vehicle mobility, the system continuously monitors the vehicle's position and enables electromagnetic wave output only when the vehicle is within authorized areas. This dynamic approach maintains ease of operation within permitted zones while adapting to the vehicle's movement, resolving the contradiction between operational simplicity and geographical flexibility.
3Reliability
If area verification is implemented to prevent unauthorized electromagnetic wave output, then regulatory compliance is improved, but system complexity increases
Solution Approach 1:
The system integrates area verification functionality into the existing reader control architecture, allowing the same control unit to perform both part identification operations and location-based authorization checks. By making the control system multi-functional, the patent achieves regulatory compliance without adding separate dedicated hardware for area verification, thus minimizing the increase in system complexity while maintaining high reliability.

AI summary
A communication system provided to a working vehicle includes: an information receiving unit that communicates with identification devices and receives identification information; a first area information storage that stores first area information indicating an area where use of the information receiving unit is permitted; a comparing unit that compares the first area information with second area information indicating an area where the working vehicle is used; and a communication control unit that prohibits the information receiving unit from outputting electric waves when the second area information is not included in the first area information.
