Solution Overview

Problem

Base stations of wireless LAN are often installed by multiple unspecified users, making it difficult to register their information in advance, and updates become cumbersome due to potential additions or changes in installation positions.

Innovation Solution

A communication apparatus and information management system that automatically reflect position information of base stations by storing and associating time-stamped position and base station identification information, allowing for automatic updates and accurate registration of base station information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If base station information is manually registered in advance, then initial accuracy is improved, but maintenance complexity increases due to frequent updates needed

Engineering Contradiction:
Improvebase station information accuracyVSAvoidinformation management complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system enables self-service by allowing base stations to automatically register their own position information with the information management apparatus. Each base station transmits its identification and position data autonomously when it detects a movement amount exceeding a threshold, eliminating the need for manual registration and reducing maintenance complexity while maintaining information accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms where the information management apparatus monitors base station position changes and automatically updates registered information when movements are detected. The movement detection unit continuously monitors position data and triggers automatic updates, creating a closed-loop system that maintains accuracy without manual intervention.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If manual updates are performed for each base station addition or change, then information accuracy is maintained, but time consumption increases

Engineering Contradiction:
Improvebase station information accuracyVSAvoidupdate time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary action by pre-setting position thresholds for each base station. When a base station moves beyond its predetermined threshold range, the system automatically detects and registers the position change. This pre-configured threshold mechanism enables rapid automatic updates without requiring manual verification or processing time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Base stations autonomously monitor their own position changes and automatically transmit updated information when movements exceed thresholds. This self-service capability eliminates the need for manual update operations, significantly reducing the time required to maintain accurate base station information while new base stations are added or existing ones move.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If all base stations are monitored continuously, then detection accuracy is improved, but system resource consumption increases

Engineering Contradiction:
Improveposition change detection accuracyVSAvoidsystem resource consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system applies local quality by setting individual position thresholds for each base station based on its specific characteristics and environment. Instead of uniform continuous monitoring, each base station has its own customized threshold that triggers monitoring and update operations only when necessary, optimizing resource consumption while maintaining detection accuracy for position changes that matter.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system performs partial monitoring by only actively tracking base stations that have moved beyond their predetermined thresholds rather than continuously monitoring all base stations at all times. This partial action approach reduces system resource consumption by focusing computational and communication resources only on base stations with significant position changes, while still maintaining accurate detection of relevant movements.

Inventive Principle:
Principle #16Partial or excessive action
