Solution Overview

Problem

Existing transportation systems face challenges in accurately recognizing the type of system control and activating the correct control functions, leading to potential errors and safety risks due to the complexity of components and dependencies between functions.

Innovation Solution

The method involves recognizing components through identification numbers, determining if they belong to an approved combination, and only activating corresponding control functions, ensuring that only the correct drivers are loaded and executed, thereby reducing errors and safety risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a common control program is used for different system control types, then development effort is reduced, but the risk of incorrect configuration and safety errors increases

Engineering Contradiction:
Improvedevelopment effortVSAvoidconfiguration accuracy
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The system performs preliminary recognition of the system control type before activating any control functions. The method checks the combination of components to identify the specific system control type (e.g., freight elevator, passenger elevator) and only then activates the appropriate control functions. This preliminary action prevents incorrect configurations by ensuring that control functions are activated in the correct sequence based on the recognized system type.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes parameters (control function activation status) based on the recognized system control type. Different system control types have different parameter configurations - for example, a passenger elevator system activates air conditioning control functions while a freight elevator system does not. The method dynamically adjusts which control functions are activated based on the identified system type, resolving the contradiction between using a common program and ensuring correct configuration.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If many control functions are included in the control program to handle complex systems, then adaptability is improved, but the number of rules and potential error sources increases

Engineering Contradiction:
Improvesystem functionalityVSAvoidcontrol program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control program is segmented into different system control types (freight elevator, passenger elevator, high-rise building elevator) with specific control functions activated for each type. Instead of having all possible functions active in a single complex program, the method divides the control program into modular segments that are selectively activated based on the recognized system type, reducing the effective complexity for each specific application.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control program is designed with universal multi-functionality to handle different system control types. The same base control program can control various elevator types (freight, passenger, high-rise) by selectively activating appropriate control functions based on the recognized system type. This universality allows one control program to serve multiple purposes without requiring separate dedicated programs for each system type.

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

3Ease of operation

If manual parameter entry is required to activate control functions, then flexibility is improved, but the risk of human error increases

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoiderror rate
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs self-service by automatically recognizing the system control type based on the combination of components and autonomously activating the appropriate control functions without requiring manual parameter entry. The method checks the installed components (e.g., air conditioning system, safety circuits, call control) and automatically determines which control functions should be activated, eliminating human error while maintaining configuration flexibility.

Inventive Principle:
Principle #25Self-service

AI summary

The method begins by activating the conveying installation, recognizing the ID numbers of the components, such as installation controls e.g. safety feed, brake control, air conditioning, of the conveying installation, and checking whether the ID numbers belong into permitted component combinations. The type of installation control is recognized, after which different control functions (12-18) in the control program (11) are activated depending on the recognized installation control type. The conveying installation is released for operation. An independent claim is also included for a conveying installation.
