Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual programming of unique addresses for landing fixtures is used, then the configuration process can be completed, but it is time-consuming and prone to human error

Engineering Contradiction:
Improveaccuracy of address programmingVSAvoidconfiguration time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical manual programming process with an automated wireless communication system. The wireless device transmits unique identification codes to landing fixtures automatically, eliminating the need for mechanics to manually set switches on electronic boards. This substitution of mechanical operation with wireless automated communication resolves the contradiction by simultaneously improving accuracy (eliminating human error) and reducing configuration time.

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

Solution Approach 2:

The landing fixtures are equipped with the capability to receive and store unique identification codes autonomously through wireless communication. Instead of requiring external manual programming, the fixtures self-configure by automatically receiving their unique addresses from the wireless device, thereby eliminating the time-consuming and error-prone manual process while ensuring accurate configuration.

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If manual programming of landing fixtures is performed, then configuration can be achieved, but the complexity of the configuration process increases

Engineering Contradiction:
Improveease of configurationVSAvoidconfiguration process complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent extracts the complex programming logic from the manual configuration process and consolidates it into a centralized wireless communication device. Instead of requiring mechanics to understand and manually configure each landing fixture's electronic board, the unique identification codes are generated and transmitted centrally, simplifying the configuration process and reducing its complexity while improving ease of manufacture.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If unique addresses are manually assigned to each landing fixture, then individual communication is enabled, but the risk of errors increases

Engineering Contradiction:
Improveaccuracy of address assignmentVSAvoidsimplicity of configuration
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the manual mechanical process of setting switches and assigning addresses with an automated wireless transmission system. The wireless device automatically assigns unique identification codes to landing fixtures through wireless communication, eliminating human error in address assignment while maintaining the simplicity of the configuration process. This resolves the contradiction by improving reliability without sacrificing ease of operation.

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

AI summary

A method of configuring an elevator system (1), comprises positioning a wireless communication device (4, 4') on or within an elevator car (2). When the elevator car (2) is in the vicinity of a landing floor (8a) of the elevator system (1), the wireless communication device (4, 4') transmits data comprising a unique identification code, or part thereof (26, 44) to a landing fixture (10a, 12a, 14a, 16a, 18a) on the landing floor (8a). The landing fixture (10a, 12a, 14a, 16a, 18a) receives the data. The method further includes, based on the received data, the landing fixture (10a, 12a, 14a, 16a, 18a) storing the unique identification code (44).
