Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual programming of unique addresses is used for landing fixtures, then the configuration process allows human control and verification, but the process becomes time-consuming and error-prone

Engineering Contradiction:

Improveaccuracy of address programmingVSAvoidconfiguration time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the manual mechanical process of programming addresses (physically opening housings, setting switches on electronic boards) with an automated wireless communication system. The wireless communication device automatically transmits unique identification codes to landing fixtures, eliminating the need for manual intervention and thereby reducing both configuration time and human error while maintaining reliability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The landing fixtures are equipped with the capability to automatically receive and store unique identification codes via wireless communication. This self-service mechanism allows the fixtures to configure themselves without requiring manual programming, thereby reducing configuration time and eliminating human error in the address assignment process.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If manual configuration methods are used, then flexibility in programming is maintained, but the complexity of the configuration process increases

Engineering Contradiction:

Improvesimplicity of configuration processVSAvoidcomplexity of configuration procedure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces complex manual configuration procedures with a simple wireless communication system. The wireless communication device automatically manages the transmission and assignment of unique identification codes, transforming a complex multi-step manual process into a simple automated operation that enhances ease of operation while reducing procedural complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The wireless communication device serves as an intermediary between the control system and the landing fixtures, automatically handling the complex task of address assignment. This intermediary device simplifies the configuration process by absorbing the complexity of coordinate system management and unique ID generation, leaving the user with a simple point-and-click interface.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If automatic wireless configuration is implemented, then configuration time is reduced and errors are minimized, but the system requires additional wireless communication components

Engineering Contradiction:

Improveconfiguration speedVSAvoidsystem component requirements

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The wireless communication device serves multiple functions: it transmits unique identification codes, manages coordinate system transformations, and communicates with multiple landing fixtures. By consolidating these functions into a single multi-functional device, the patent achieves high configuration productivity without proportionally increasing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The wireless communication device acts as an intermediary that bridges the control system and multiple landing fixtures, handling all complex communication and coordinate management tasks. This single intermediary component enables rapid automatic configuration of multiple fixtures without requiring each fixture to have complex built-in configuration capabilities, thereby improving productivity while keeping individual fixture complexity low.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method of configuring an elevator system (1), includes 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).
