Solution Overview

Problem

Conventional elevator systems require active user interaction for service requests, which can lead to inefficiencies and may not effectively manage passenger flow, resulting in increased waiting times.

Innovation Solution

A method and apparatus that allow users to passively request elevator service through mobile devices connected to networks, using profiles and location validation to efficiently allocate resources and minimize nuisance calls, enabling service requests to be fulfilled without the need for direct interaction with public devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If conventional buttons, keypads, or touchscreen devices are used for elevator service requests, then users can request elevator service, but user waiting times increase and passenger flow management becomes inefficient

Engineering Contradiction:
Improveuser waiting timeVSAvoidpassenger flow management efficiency
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

The system performs preliminary detection of passengers in the detection area before they actually request service. The processor detects passengers using sensors (camera, RFID, or biometric sensors) and pre-processes their service requests, validating their locations and preparing service allocation in advance, thereby reducing actual waiting time when they reach the elevator.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces mechanical button-pressing or touchscreen interaction with automated detection systems. Instead of users manually activating buttons or keypads, the system uses image recognition cameras, RFID readers, or biometric sensors to automatically detect and identify users, substituting manual mechanical input with automated optical, electromagnetic, or biological detection methods.

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

2Productivity

If automated detection systems are implemented to reduce waiting times, then passenger flow management improves, but device complexity increases

Engineering Contradiction:
Improvepassenger flow management efficiencyVSAvoiddetection and validation system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system employs multi-functional sensors that can perform multiple detection tasks. For example, a camera system can simultaneously detect user presence, recognize faces for identification, and validate location within the detection area. This consolidation of multiple functions into single sensors or processing routines reduces overall system complexity despite the advanced capabilities required.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a gateway as an intermediary component between the sensors and the elevator control system. The gateway handles data processing, validation, and communication protocols, acting as a buffer that simplifies the architecture by centralizing complex processing tasks rather than distributing them across multiple components.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If passive service requests through mobile devices are allowed, then hygiene is improved by minimizing contact with public devices, but reliability of service requests may be compromised

Engineering Contradiction:
Improvehygiene risk from device contactVSAvoidservice request validation
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

Instead of using physical mobile devices as the primary interface, the system creates digital copies or representations of user identity through biometric data (face recognition, fingerprint, iris scan). These biometric copies serve as reliable identifiers that can be validated remotely without requiring physical contact with shared devices, maintaining both hygiene and reliability.

Inventive Principle:
Principle #26Copying

AI summary

Embodiments are directed to receiving, by a computing device comprising a processor, a request for at least one service associated with an elevator system from a mobile device over a cellular network, validating the request based on a determined location of the mobile device, and causing at least one resource associated with the at least one service to be scheduled based on the validating indicating that the request is approved.
