Problem

The configuration process for modular safety switching devices is often complex and requires significant expertise, making it difficult to assemble the devices correctly and efficiently.

Innovation Solution

A software-based configuration tool with a graphical user interface simplifies the process by automatically selecting electronic modules, generating alphanumeric identifiers for each module, and producing a wiring diagram, allowing users to specify safety functions and logic requirements without specialized knowledge, and storing the configuration data in a database for easy retrieval during assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual configuration methods are used for modular safety switching devices, then configuration flexibility and customization are improved, but configuration complexity and time consumption increase significantly

Engineering Contradiction:
Improveconfiguration flexibilityVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces manual configuration processes with an automated software-based configuration tool that generates configuration data sets, module identifiers, and wiring diagrams automatically. This substitution of manual mechanical configuration with automated software processing resolves the contradiction by maintaining configuration flexibility through customizable safety functions while dramatically reducing configuration complexity and time consumption.

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

Solution Approach 2:

The configuration tool performs preliminary actions by automatically selecting electronic modules, generating unique alphanumeric identifiers for each module, determining optimal module arrangements, and creating wiring diagrams before the actual assembly process. This preliminary automated configuration reduces on-site complexity and ensures correctness, allowing users to focus only on physical assembly rather than complex configuration decisions.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automated module selection is implemented, then configuration time and expertise requirements are reduced, but the need for additional software tools and processing increases

Engineering Contradiction:
Improveconfiguration efficiencyVSAvoidsoftware tool complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The configuration tool is designed as a universal software solution that handles multiple configuration tasks including module selection, identifier generation, arrangement optimization, and wiring diagram creation. This multi-functional approach consolidates what could be multiple separate complex tools into a single integrated system, improving productivity while managing software complexity through consolidation rather than proliferation of separate tools.

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

Solution Approach 2:

The configuration tool operates autonomously to select appropriate electronic modules based on safety functions, generate unique identifiers, and create configuration data sets without requiring expert intervention. This self-service capability allows the system to perform complex configuration tasks automatically, improving productivity while the software manages its own complexity through automated decision-making algorithms.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If unique alphanumeric identifiers are generated for each module, then assembly precision and correctness are improved, but data processing and storage requirements increase

Engineering Contradiction:
Improveassembly precisionVSAvoiddata volume
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The configuration system segments the modular safety switching device into individually identifiable electronic modules, each assigned a unique alphanumeric identifier. This segmentation approach improves assembly precision by enabling precise tracking and placement of each module according to the generated wiring diagrams and configuration data, while the modular nature of the identifiers keeps data processing manageable through structured, hierarchical naming conventions.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If configuration data is stored in a database for retrieval, then assembly ease and correctness are improved, but system complexity and storage requirements increase

Engineering Contradiction:
Improveassembly easeVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The configuration tool performs preliminary configuration work by storing all necessary assembly information including module identifiers, arrangement sequences, and wiring diagrams in a database before the actual assembly process. This preliminary action makes the subsequent assembly operation straightforward and error-proof, as workers can retrieve pre-processed configuration data without needing to perform complex configuration decisions during assembly, thereby improving ease of operation while the system manages complexity through advance preparation.

Inventive Principle:
Principle #10Preliminary action
