Solution Overview

Problem

Elevator systems face inefficiencies and deteriorated passenger experience due to false inputs, such as fictitious calls and incorrect passenger information, leading to increased waiting times, crowding, and energy consumption.

Innovation Solution

An elevator system that monitors passengers within and outside the car, determines passenger parameters, and compares them with input data to identify and correct false inputs, optimizing operations and preventing adverse effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If destination dispatching with additional passenger information is implemented, then occupancy optimization and individual passenger demands are fulfilled, but the system becomes vulnerable to false inputs that reduce efficiency

Engineering Contradiction:

Improveoccupancy optimizationVSAvoidsystem efficiency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system continuously monitors passenger parameters (detected by sensors) and compares them with input parameters (from control panels). This feedback loop allows the system to detect discrepancies caused by false inputs and correct the control data accordingly, maintaining reliability while preserving adaptability features

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system automatically detects and corrects false inputs without requiring manual intervention. The correction mechanism operates autonomously by comparing sensor data with control input and adjusting the dispatching decisions, allowing the system to self-correct while maintaining optimized occupancy features

Inventive Principle:

Principle #25Self-service

2Ease of operation

If passengers are allowed to input additional information (cardinality, volume occupancy), then individual demands are fulfilled and occupancy is optimized, but false information leads to increased waiting times and crowding

Engineering Contradiction:

Improveindividual passenger demands fulfillmentVSAvoidpassenger waiting time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system uses sensor-based passenger parameter detection as feedback to verify control inputs. When false information is detected (e.g., incorrect cardinality or volume occupancy), the system automatically corrects the data, preventing unnecessary waiting times and crowding while maintaining ease of operation for legitimate passengers

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Manual passenger information input is supplemented and verified by automated sensor detection. The optical sensors and image processing systems replace manual verification, automatically detecting passenger presence and characteristics to validate control inputs, thereby reducing errors without complicating the user interface

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If control inputs are accepted without verification, then system operation is simple, but false inputs cause unnecessary stops and increased energy consumption

Engineering Contradiction:

Improvecontrol system simplicityVSAvoidelevator energy consumption

Core Design Contradiction:

Device complexityVSUse of energy by moving object

Solution Approach 1:

The system implements automatic verification by comparing sensor-detected passenger parameters with control input parameters. This feedback mechanism detects false inputs that would cause unnecessary stops and energy waste, correcting the data before dispatching decisions are made, thereby maintaining simple operation while reducing energy consumption

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The verification and correction process operates autonomously without requiring additional manual steps from passengers. The system self- verifies control inputs against sensor data and automatically corrects false information, preventing unnecessary elevator stops and energy consumption while keeping the control interface simple

Inventive Principle:

Principle #25Self-service

4Adaptability or versatility

If multiple calls are allowed to achieve empty elevator car or faster service, then passenger preferences are accommodated, but gaming behavior increases waiting times and reduces system capacity

Engineering Contradiction:

Improvepassenger service flexibilityVSAvoidelevator system capacity

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The system monitors passenger parameters and control inputs to detect gaming behavior patterns (multiple calls from same passenger). The feedback mechanism identifies such anomalies and corrects the control data to reflect actual passenger needs, maintaining service flexibility while preserving system capacity and productivity

Inventive Principle:

Principle #23Feedback
