Solution Overview

Problem

Conveyor systems require significant configuration and parameterization effort due to non-adapted programmable logic controllers for switch and linear segments, leading to high costs and limited communication options, making them economically inefficient.

Innovation Solution

Implementing a uniform concept for logic modules across all segments, with identical sensor inputs and control outputs, allowing for standardized wiring and reduced configuration effort, and using identical hardware for all linear-type logic modules and two types of switch-type logic modules for merge and divert functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If different types of logic modules (programmable for switch segments, hard-wired for linear segments) are used, then the control functionality is achieved, but the configuration and parameterization effort increases significantly

Engineering Contradiction:
Improvecontrol functionalityVSAvoidconfiguration effort
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies universality by making all logic modules (both switch-type and linear-type) based on the same hardware platform with identical sensor inputs and control outputs. This allows a single module design to perform multiple functions depending on configuration, eliminating the need for different hardware types and significantly reducing configuration effort.

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

Solution Approach 2:

The patent uses parameter changes by allowing the same logic module hardware to be configured for different functions (switch or linear segment control) through software or configuration parameters rather than hardware differences. This enables functional adaptability without increasing physical complexity.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If programmable logic controllers are used for switch segments, then the control flexibility is improved, but the production cost increases

Engineering Contradiction:
Improvecontrol flexibilityVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent reduces production cost by using a universal logic module design for both switch and linear segments. Instead of manufacturing expensive programmable controllers for switch segments and simpler modules for linear segments, a single module type is produced, achieving economies of scale while maintaining control flexibility through configuration.

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

Solution Approach 2:

The patent uses copying by replicating the same logic module hardware design across all segments. Rather than creating different hardware architectures, the same proven design is copied and configured differently, reducing development and manufacturing costs while maintaining functionality.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If non-adapted logic modules are used for switch and linear segments, then the specific control requirements are met, but the communication options between modules are limited

Engineering Contradiction:
Improvecontrol specificityVSAvoidcommunication options
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enhances communication options by making all logic modules based on the same hardware platform with identical interfaces and capabilities. This universality allows any module to communicate with any other module in a standardized way, expanding communication possibilities compared to specialized modules with limited compatibility.

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

AI summary

The system has conveying segments e.g. linear segments (1'-5') and switch segment (13') i.e. diverting switch segment, where linear type logic modules (1-5) and switch type logic module (13) are assigned to respective segments. Each module has a sensor input and a control output for a drive component (A) of the respective segments. The module (13) has an additional control output for another drive component to control a merging or diverting function. The modules control the respective segments. The inputs and/or the outputs for the drive components are identically formed with all modules.
