Solution Overview

Problem

Existing technologies for securing data on portable control devices fail to reliably delete data when the device is outside a designated area, leading to security concerns and communication limitations due to radio wave strength thresholds that are difficult to set and manage.

Innovation Solution

A portable control device system that determines data deletion based on the device's position using a satellite positioning system, allowing for precise location tracking and secure data management within designated areas, enabling the storage and display of control data within permitted zones and its deletion outside those zones.

VSEngineering Contradiction Analysis

1Reliability

If radio wave strength threshold is set for data deletion, then security is improved, but device complexity increases due to difficult layout-dependent settings

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically obtains positional information from GPS satellites and performs autonomous comparison with stored boundary data. The device independently determines whether it is within the safe area and executes data deletion accordingly, eliminating the need for manual threshold adjustments by users or administrators

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent transforms the configuration approach from setting radio wave strength thresholds (which requires layout analysis and minute adjustments) to defining geographical boundaries using coordinate data. This parameter change simplifies the setup process, as boundary definitions can be directly input without considering signal propagation characteristics
