Solution Overview

Problem

In high-rise buildings, users often face inefficiencies when trying to travel between elevator groups, requiring multiple destination calls if the source and destination floors are not in the same elevator group, leading to increased travel time and inconvenience.

Innovation Solution

A controller-based system that manages elevator transportation by determining the user's location, instructing the appropriate elevators to meet at a common floor, and optimizing travel paths to minimize delays and wait times, allowing for seamless handoff between elevators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple destination calls are required to travel between elevator groups, then elevator group segmentation is maintained for traffic management, but travel time and user convenience deteriorate

Engineering Contradiction:
Improveelevator traffic management efficiencyVSAvoidtravel time between floors
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple elevator groups into a coordinated system where elevators from different groups can be sequentially dispatched to serve a single continuous journey. The controller merges the transportation tasks across elevator groups, allowing the first elevator to take the passenger to an intermediate floor and the second elevator to complete the journey to the destination floor, thereby reducing total travel time while maintaining group segmentation benefits

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If multiple destination calls are required to travel between elevator groups, then elevator group segmentation is maintained, but ease of operation deteriorates

Engineering Contradiction:
Improveelevator traffic management efficiencyVSAvoiduser convenience
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system provides self-service by automatically coordinating between elevator groups without requiring user intervention. The controller autonomously determines the sequence of elevators to dispatch, calculates optimal timing, and manages the handoff between elevators, freeing the user from the burden of making multiple manual destination calls while maintaining efficient traffic management

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The controller acts as an intermediary that coordinates between different elevator groups and the user. It receives the single destination request, processes the routing logic, and manages the interaction between the first and second elevators, thereby simplifying the user interface while maintaining systematic control over multi-elevator coordination

Inventive Principle:
Principle #24Intermediary (Mediator)
