Solution Overview

Problem

Existing systems lack efficient methods for enhancing location-based information provision to electronic devices, particularly in scenarios where devices need to autonomously perform physical actions based on their capabilities and environment.

Innovation Solution

An apparatus comprising a processor and memory configured to request location-based information, transmit capability information, receive dynamically created physical challenges, and control the device to autonomously perform actions based on these challenges, including movements, sounds, haptic outputs, and display outputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If location-based information is provided to electronic devices without verification, then information provision efficiency is improved, but security is worsened

Engineering Contradiction:
Improveinformation provision efficiencyVSAvoidsecurity
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary verification by transmitting capability information and receiving dynamically created physical challenges before providing location-based information. This preliminary action ensures that only verified devices with appropriate capabilities receive the information, resolving the contradiction between efficiency and security.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If physical challenges are implemented for device verification, then security is improved, but device complexity is worsened

Engineering Contradiction:
ImprovesecurityVSAvoidverification process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system changes parameters by transmitting capability information that describes device features and receiving dynamically created physical challenges tailored to those capabilities. This parameter-based approach allows verification without requiring fixed complex procedures, resolving the contradiction between security and complexity.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If capability information is transmitted for each verification request, then verification accuracy is improved, but communication overhead is worsened

Engineering Contradiction:
Improveverification accuracyVSAvoidcommunication overhead
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system transmits only the necessary capability information required for verification rather than complete device specifications. This partial action approach provides sufficient verification accuracy while minimizing communication overhead, resolving the contradiction between precision and information loss.

Inventive Principle:
Principle #16Partial or excessive action
