Communication Device Dual Range Priority Segmentation

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional communication devices often fail to establish communication between an intended communication device and terminal due to prioritization issues, where a terminal with a lower priority level may not connect unless within a specific range, leading to delayed or unsuccessful communication.

Innovation Solution

Implementing a communication device with two distinct communication ranges - a short range and a long range - where terminals in the short range can communicate regardless of priority, and those in the long range can connect only if their priority is higher than a predetermined level, allowing for prioritization-based connection attempts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If communication is permitted to low priority terminals within communication range, then communication coverage is expanded, but communication reliability with intended terminals deteriorates

Engineering Contradiction:

Improvecommunication rangeVSAvoidcommunication reliability

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The communication range is segmented into two distinct zones: a short communication range and a long communication range. The short range ensures high reliability for intended terminals, while the long range expands coverage for low priority terminals, resolving the contradiction between communication reliability and coverage area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different communication policies are applied to different spatial zones. Within the short communication range, communication is permitted to all terminals regardless of priority level, ensuring reliable communication with intended terminals. Outside this range but within the long communication range, communication is restricted to high priority terminals only, managing coverage expansion without compromising reliability.

Inventive Principle:

Principle #3Local quality

2Productivity

If priority-based communication is implemented, then communication efficiency is improved, but communication time for low priority terminals increases

Engineering Contradiction:

Improvecommunication efficiencyVSAvoidcommunication establishment time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

Terminals are segmented into two groups based on their spatial position: those within the short communication range (priority-agnostic group) and those outside this range (priority-filtered group). This segmentation allows low priority terminals to establish communication quickly when within the short range, while maintaining efficiency for distant terminals through priority-based selection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system pre-establishes the short communication range as a high-priority zone where any terminal can connect immediately. This preliminary action ensures that low priority terminals can quickly establish communication by simply entering the short range, reducing their communication establishment time without compromising overall system efficiency.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple terminals are served simultaneously, then service coverage is expanded, but communication stability deteriorates

Engineering Contradiction:

Improveservice coverageVSAvoidcommunication stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The service coverage is segmented into two distinct zones with different operational characteristics. The short communication range provides stable, priority-agnostic service for intended terminals, while the long communication range provides extended coverage with priority-based service restrictions, maintaining communication stability while expanding overall service coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different service qualities are provided in different spatial locations. Within the short communication range, the system provides stable communication to any terminal regardless of priority level. Outside this range but within the long communication range, the system restricts service to high priority terminals only, ensuring communication stability in the critical short-range zone while maintaining expanded service coverage.

Inventive Principle:

Principle #3Local quality

AI summary

A communication device including a communicator and a communication controller is provided. The communicator has at least two communication ranges including a short communication range and a long communication range longer than the short communication range. The communication controller permits the communicator to perform communication with a terminal present in the short communication range regardless of a priority level of the terminal. The communication controller permits the communicator to perform communication with a terminal present in the long communication range and out of the short communication range when a priority level of the terminal is higher than a predetermined priority level.
