External Wireless Transmitter for Visitor Identity Verification

Solution Overview

Problem

Existing visitor identification systems are complex and require installation within the residence, making them costly and difficult to implement, especially for vulnerable individuals such as seniors living alone, who need a simplified method to verify visitors before allowing them into their homes.

Innovation Solution

A wireless transmitter installed outside the residence broadcasts a near-field wireless signal upon manipulation, allowing a visitor application to extract a unique identifier and transmit it to a management server, which verifies the visitor's identity by checking resident information and providing communication resources for a video call, enabling the resident to verify the visitor without needing a complex system inside the home.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional visitor identification system is installed within the residence, then the resident can verify visitor identity, but the system becomes complex and costly

Engineering Contradiction:

Improvevisitor identity verificationVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the visitor identification function from the interior residence system and places it outside at the entrance. The wireless transmitter is installed externally and communicates with the resident's terminal via near-field wireless signal, eliminating the need for complex internal system installations while maintaining verification capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a wireless transmitter as an intermediary device between the visitor and the resident's identification system. This external transmitter communicates with the resident's terminal through near-field wireless signals, serving as a mediator that simplifies the overall system architecture by removing the need for internal installations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a conventional visitor identification system is installed within the residence, then the resident can verify visitor identity, but the installation cost increases

Engineering Contradiction:

Improvevisitor identity verificationVSAvoidinstallation cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent extracts the visitor identification function from the interior residence system and places it outside at the entrance. The wireless transmitter is installed externally and communicates with the resident's terminal via near-field wireless signal, eliminating the need for complex internal system installations while maintaining verification capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses inexpensive near-field wireless communication technology (such as Bluetooth or WiFi) instead of expensive wired infrastructure. The wireless transmitter and resident terminal communicate through standard wireless protocols, significantly reducing installation costs and making the system more accessible to ordinary residents

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If a conventional visitor identification system is installed within the residence, then the resident can verify visitor identity, but the system becomes difficult to implement

Engineering Contradiction:

Improvevisitor identity verificationVSAvoidsystem implementation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the visitor identification function from the interior residence system and places it outside at the entrance. The wireless transmitter is installed externally and communicates with the resident's terminal via near-field wireless signal, eliminating the need for complex internal system installations while maintaining verification capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent enables the system to serve itself by automatically detecting when a visitor approaches and triggering the identification process without requiring manual intervention. The wireless transmitter automatically communicates with the resident's terminal when a visitor is detected, and the system automatically manages the verification process through the management server

Inventive Principle:

Principle #25Self-service
