Solution Overview

Problem

The existing methods for setting floor assignments of operating units in elevator installations are time-consuming and labor-intensive, requiring manual configuration of switches on each floor, which is costly and prone to errors.

Innovation Solution

A method that involves moving the elevator car to each floor, activating the operating unit, transmitting position data from a sensor unit to the operating unit or central control unit, and storing this data in a memory unit, allowing for automated configuration without manual switch setting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual switch configuration is used on each floor for setting floor assignments, then the setting process can be performed with simple equipment, but the process becomes time-consuming and labor-intensive

Engineering Contradiction:
Improvesimplicity of equipmentVSAvoidsetting speed
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The patent replaces the manual mechanical switch configuration system with an automated data transmission system. The control unit automatically transmits floor assignment data to operating units via a communication bus, eliminating the need for manual switch setting while dramatically increasing setting speed and productivity

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

Solution Approach 2:

The operating units automatically receive and store floor assignment data from the control unit without requiring manual intervention. The system performs self-configuration through automated data transmission and storage, reducing labor requirements while maintaining equipment simplicity

Inventive Principle:
Principle #25Self-service

2Device complexity

If manual switch configuration is used on each floor, then equipment costs are reduced, but the process requires more personnel and time

Engineering Contradiction:
Improveequipment simplicityVSAvoidsetting time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent substitutes manual mechanical switch configuration with an automated electronic data transmission system. The control unit transmits floor assignment data automatically to operating units through a communication bus, eliminating time-consuming manual operations while keeping the overall system relatively simple

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

3Device complexity

If manual switch setting is performed by fitters on each floor, then no additional automated equipment is needed, but the process is prone to human errors

Engineering Contradiction:
Improveautomation levelVSAvoidsetting accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent replaces manual switch configuration with automated electronic data transmission. The control unit automatically sends floor assignment data to operating units, eliminating human error in the configuration process while maintaining appropriate automation levels

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

Solution Approach 2:

The system incorporates acknowledgment signals where operating units confirm receipt of floor assignment data to the control unit. This feedback mechanism ensures accurate data transmission and storage, significantly improving setting reliability by verifying each configuration step

Inventive Principle:
Principle #23Feedback

4Productivity

If automated data transmission is implemented for floor assignment, then setting speed and accuracy improve, but the device complexity increases

Engineering Contradiction:
Improveconfiguration speedVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent utilizes an existing communication bus system that serves multiple functions in the elevator control system. By repurposing this existing infrastructure for floor assignment data transmission, the patent achieves automated configuration without adding significant system complexity

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

Solution Approach 2:

The patent combines the floor assignment configuration function with the existing communication bus infrastructure. Instead of creating a separate dedicated transmission system, the configuration data is merged into the existing communication protocol, reducing overall system complexity while maintaining high configuration speed

Inventive Principle:
Principle #5Merging (Combining)
