Solution Overview

Problem

Existing authentication systems for spaces, such as buildings or vehicles, face inefficiencies when authenticating multiple locations or remote areas, particularly when manual inspection by inspectors is not feasible, and there is a need for a system that can efficiently perform authentication while minimizing sensor processing burden.

Innovation Solution

A networked system of sensors and an authentication server that collects and processes environmental data wirelessly, performs calibration and fraud detection, and issues electronic authorization certificates, allowing remote authentication and efficient management of sensor installation and calibration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual inspection by inspectors is used for space authentication, then authentication accuracy can be ensured, but authentication efficiency and productivity deteriorate when multiple locations or remote areas need to be authenticated

Engineering Contradiction:

Improveauthentication accuracyVSAvoidauthentication efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The sensor performs self-calibration using pre-stored reference data and self-diagnosis to detect fraud, eliminating the need for manual inspector intervention. The authentication system automatically processes sensor data and issues certificates without human inspection, resolving the contradiction between accuracy and efficiency.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical inspection with an automated electronic authentication system. Sensors wirelessly transmit data to an authentication server that automatically validates environmental criteria and issues electronic certificates, substituting human inspectors with automated computational processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If sensors perform frequent calibration and data transmission to ensure authentication reliability, then measurement precision improves, but energy consumption and device complexity increase

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidsensor energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The sensor performs calibration and data transmission at predetermined intervals rather than continuously. The authentication server requests data at specific intervals, and the sensor transmits only when prompted or when environmental thresholds are exceeded, reducing energy consumption while maintaining authentication reliability.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The sensor autonomously determines when calibration is needed based on pre-stored reference data and environmental conditions. The sensor self-manages its calibration schedule and data transmission timing without requiring constant external control, optimizing energy usage while ensuring authentication reliability.

Inventive Principle:

Principle #25Self-service

3Reliability

If comprehensive environmental monitoring and fraud detection are implemented, then authentication reliability improves, but device complexity and processing burden increase

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidsensor processing burden

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system divides functionality between the sensor and authentication server. The sensor handles basic environmental monitoring and data transmission, while the authentication server performs complex fraud detection, data validation, and certificate issuance. This segmentation reduces sensor processing burden while maintaining comprehensive authentication reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The authentication server acts as an intermediary between the sensor and the authentication process. It receives raw data from sensors, performs fraud detection using pre-stored reference data, validates environmental criteria, and issues certificates. This intermediary approach simplifies sensor complexity while ensuring comprehensive authentication reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)
