Solution Overview

Problem

Existing authentication systems for spaces, such as buildings or vehicles, face inefficiencies when authenticating multiple locations or remote sites, particularly in the absence of real-time inspector visits, and lack robustness against tampering and calibration fraud.

Innovation Solution

A networked system of sensors and an authentication server that autonomously collect and analyze environmental data, perform calibration, detect tampering, and issue electronic certificates, while allowing for remote authentication and fraud detection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual inspection methods are used for space authentication, then authentication reliability is high, but authentication time and labor cost increase significantly

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The sensor performs self-calibration and self-monitoring functions, automatically detecting its own operational status and environmental conditions without requiring manual inspection. The authentication server autonomously verifies sensor data and issues certificates, eliminating the need for inspector visits while maintaining authentication reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical inspection with automated electronic sensing and digital authentication. Sensors electronically measure environmental parameters, transmit data via communication networks, and receive automated verification through electronic certificates, substituting the manual inspection process with an automated information-based system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If sensors are deployed in remote locations without inspector visits, then authentication efficiency improves, but risk of tampering and fraud increases

Engineering Contradiction:

Improveauthentication efficiencyVSAvoiddata integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The authentication server continuously receives sensor data, verifies calibration status, monitors for tampering indicators, and provides feedback through electronic certificates. This closed-loop feedback system enables remote authentication while maintaining data integrity through ongoing verification and authentication of sensor outputs.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Sensors perform preliminary self-calibration and self-diagnosis before data collection, establishing a known accurate baseline. The authentication server performs preliminary verification of sensor credentials and calibration certificates before accepting measurements, preventing fraud before it occurs rather than detecting it after compromise.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If multiple sensors are networked for comprehensive monitoring, then measurement precision improves, but system complexity increases

Engineering Contradiction:

Improveenvironmental measurement precisionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The authentication server performs multiple functions including data collection, calibration verification, tampering detection, statistical analysis, and certificate issuance through a single integrated system. Sensors are designed as universal units capable of measuring multiple environmental parameters and communicating with the central server, reducing overall system complexity while maintaining comprehensive monitoring capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges sensor calibration functions, authentication functions, and data processing functions into an integrated authentication server system. Rather than requiring separate calibration devices, authentication systems, and data processing units, the system combines these functions into a unified platform that manages multiple sensors centrally.

Inventive Principle:

Principle #5Merging (Combining)
