Solution Overview

Problem

Current systems for visitor access to non-tenant buildings require tenants to personally escort visitors or pre-register them, causing inconvenience while maintaining security and regulated access.

Innovation Solution

A method and system that uses a visitor's mobile device to generate and manage access invitations, allowing limited access to designated floors through a building management system, using digital credentials and mobile applications for secure and convenient access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tenants personally escort visitors to their floors, then security and regulated access are maintained, but tenant convenience and time are significantly reduced

Engineering Contradiction:
ImprovesecurityVSAvoidtenant convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The visitor management system enables self-service functionality where visitors independently complete the access request process through mobile devices. Visitors can request access codes, receive notifications, and gain entry without tenant intervention, while tenants retain oversight through the ability to approve or deny requests.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The building management system acts as an intermediary between tenants and visitors. It receives access requests from visitors, notifies tenants for approval, generates access codes, and manages the entire access workflow, eliminating the need for direct tenant-visitor interaction while maintaining security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If tenants pre-register visitors with building security, then access control is maintained, but the process becomes burdensome and time-consuming for tenants

Engineering Contradiction:
Improveaccess controlVSAvoidregistration time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically generating access codes and preparing visitor credentials in advance upon request approval. The building management system pre-configures access parameters, valid time periods, and floor restrictions before the visitor arrives, eliminating last-minute registration steps.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Visitors independently initiate the pre-registration process through mobile devices by requesting access codes. The system automatically handles credential generation and distribution without requiring tenant involvement in the registration process, reducing both tenant burden and processing time.

Inventive Principle:
Principle #25Self-service

3Reliability

If visitors show ID to front desk for access, then security verification is ensured, but the access process becomes lengthy and inconvenient

Engineering Contradiction:
Improvesecurity verificationVSAvoidaccess time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system replaces the mechanical process of physical ID presentation and manual verification at the front desk with electronic credential delivery via mobile devices. Access codes are digitally transmitted and automatically validated by elevator systems, eliminating the need for front desk interaction and manual ID checking.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables visitors to skip the traditional front desk verification step by delivering access codes directly to mobile devices. The electronic validation process occurs automatically in the background, allowing visitors to proceed directly to elevators without stopping at the front desk.

Inventive Principle:
Principle #21Skipping (Rushing through)

AI summary

A system and method of managing visitor access to an elevator using a mobile device of the visitor is provided. The method includes generating a visitor invitation based on a tenant input using an electronic device, receiving the visitor invitation at the mobile device of the visitor, and gaining limited access to designated floor based on limitation values contained in the visitor invitation.
