Solution Overview

Problem

In very tall buildings, efficiently identifying a preferred elevator car route for passengers with different destination floors at similar times is challenging due to multiple possible routes and varying passenger capacities, especially considering transfer floors and anticipated delays.

Innovation Solution

A method and system for determining and presenting estimated travel times for different elevator car routes, incorporating transfer times and passenger capacity, allowing users to select routes based on expected delays and capacity, and updating travel plans and arrival times on interactive displays and mobile devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple elevator car routes are provided to serve different destination floors, then passenger service coverage is improved, but route selection complexity increases

Engineering Contradiction:
Improvepassenger service coverageVSAvoidroute selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system continuously monitors elevator car positions, travel times, and passenger requests to dynamically calculate and update route options. This feedback mechanism enables the system to adapt to changing conditions and provide optimal route selections, resolving the contradiction by making the complex system responsive and intelligent rather than static and confusing

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The route selection system transitions from a static fixed-route approach to a dynamic adaptive system that recalculates routes based on real-time elevator positions, travel times, and passenger destinations. This dynamic behavior allows the system to handle multiple destinations efficiently while maintaining simple user interaction through automated recommendations

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If transfer floors are used to connect different elevator groups, then building coverage is improved, but travel time increases

Engineering Contradiction:
Improvebuilding coverageVSAvoidtravel time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system proactively identifies when transfer floor routes are necessary and calculates optimal transfer timing in advance. By predicting passenger destinations and elevator availability, the system can prepare transfer instructions beforehand and coordinate elevator arrivals to minimize waiting time at transfer floors, thus reducing the time penalty of transfers

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control system acts as an intermediary that coordinates between different elevator groups and transfer floors. It synchronizes elevator arrivals, manages passenger flow between transfers, and optimizes transfer timing to minimize delays, effectively mediating the trade-off between building coverage and travel time

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If real-time travel time calculation is implemented, then route accuracy is improved, but system complexity increases

Engineering Contradiction:
Improveroute accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical timing and coordination mechanisms with electronic sensors, processors, and communication systems. Real-time travel time calculation is achieved through electronic monitoring of elevator positions and speeds, combined with computational algorithms that quickly determine optimal routes, substituting physical complexity with intelligent processing

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

Solution Approach 2:

The control system automatically monitors its own state (elevator positions, speeds, and availability) and uses this self-collected data to calculate real-time travel times and optimize routes. This self-service capability eliminates the need for external timing devices or manual coordination, achieving high route accuracy through autonomous system intelligence

Inventive Principle:
Principle #25Self-service

AI summary

A method includes receiving a passenger request to reserve an elevator car of an elevator system to travel to a targeted destination. At least two different travel options (404A, 404B) to the targeted destination are determined based on a plurality of elevator car travel plans comprising at least two elevator cars having different travel ranges. The at least two different travel options (404A, 404B) are output to an interactive display (204). At least one of the at least two elevator cars is reserved responsive to a user selection of one of the at least two different travel options (404A, 404B).
