Solution Overview

Problem

Modern elevator systems face inefficiencies in initiating elevator service and selecting a destination floor, as passengers often have to wait and face obstructed access to buttons, necessitating a more convenient and faster method for requesting and dispatching elevator service.

Innovation Solution

The elevator system incorporates a fixture communication device with a transceiver, allowing passengers to use mobile devices to wirelessly communicate with elevator fixtures, enabling the initiation of hall and car calls by transmitting travel signals indicative of direction and destination, thereby automating the process of activating call buttons.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional manual button pressing is used, then the system is simple and reliable, but the operation is inconvenient and time-consuming

Engineering Contradiction:
Improveease of initiating elevator serviceVSAvoidcomplexity of communication system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical button-pressing system with a wireless communication system using mobile devices. The mobile device communicates with the elevator control system via wireless signals (Bluetooth, Wi-Fi, or cellular), eliminating the need for physical contact with buttons and providing more convenient operation while maintaining system reliability through established communication protocols.

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

Solution Approach 2:

The mobile device acts as an intermediary between the passenger and the elevator control system. It transmits travel requests and receives elevator status information, serving as a mediator that simplifies the user interface while the elevator control system processes the requests and manages the actual elevator operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If wireless communication is implemented, then the operation becomes convenient and fast, but the device complexity increases

Engineering Contradiction:
Improvespeed of initiating elevator serviceVSAvoidcomplexity of fixture communication device
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The fixture communication device is designed with multi-functionality, serving as both a receiver for travel requests from mobile devices and a transmitter for providing elevator status information. It integrates wireless communication capabilities, signal processing, and control functions into a single device, reducing overall system complexity despite enhanced functionality.

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

Solution Approach 2:

The system uses digital signals and data representations to copy and transmit information between the mobile device and elevator control system. Travel requests, floor selections, and status updates are transmitted as digital data rather than requiring complex mechanical or electrical signal processing, simplifying the communication architecture.

Inventive Principle:
Principle #26Copying

3Loss of time

If manual button pressing is required, then the system remains simple, but the wait time increases due to manual operation

Engineering Contradiction:
Improvewait time for elevator serviceVSAvoidconvenience of service initiation
Core Design Contradiction:
Loss of timeVSEase of operation

Solution Approach 1:

The mobile device can pre-establish communication with the elevator system and send travel requests in advance. The system can prepare elevator dispatching before the passenger actually reaches the elevator, reducing wait time by performing preliminary actions such as elevator positioning and group management calculations ahead of time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system provides real-time feedback to the mobile device regarding elevator status, estimated arrival times, and service confirmation. This feedback loop allows the system to optimize elevator dispatching based on actual conditions and provides passengers with timely information, reducing perceived wait time and improving overall service efficiency.

Inventive Principle:
Principle #23Feedback
