Solution Overview

Problem

Conveyor means with chain link belts experience polygon effects, radial forces, and friction forces on curved path sections, leading to uneven and forceful movement, making it difficult to detect and replace defective rolls and maintain smooth operation.

Innovation Solution

An endless conveyor belt with a curved path section featuring an inner guiding and rolls interacting with each chain link, along with adjustable roll positions and curvature-matched chain link faces, reduces polygon effects and friction, allowing for easy roll replacement and maintenance, and supports for articles to ensure reliable transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rolls are positioned in between the slats and the support at the moving endless conveyor belt, then smooth and constant movement of the conveyor means is ensured, but defective rolls cannot be detected easily nor can single rolls be removed easily and quickly and attached and/or replaced respectively

Engineering Contradiction:
Improvesmooth and constant movementVSAvoidroll detection and replacement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The conveyor belt is divided into modular chain links with individual guide rolls that can be independently accessed and replaced. Each chain link contains its own guide roll mounted on a mounting element, allowing segmented maintenance without stopping the entire conveyor system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of mounting rolls on the moving conveyor belt components, the guide rolls are mounted on the stationary support structure. This inversion allows rolls to be easily accessed and replaced while the conveyor belt moves continuously, resolving the contradiction between maintaining smooth movement and enabling easy repair.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If an endless conveyor belt with curved path section is used, then articles can be transported along curved paths, but polygon effects and radial forces impact on the chain links, jeopardizing smooth movement

Engineering Contradiction:
Improvecurved path transport capabilityVSAvoidsmooth movement
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The chain links are designed with curved interaction faces that match the curvature of the guide rolls. This curvature matching reduces polygon effects and radial forces by ensuring continuous contact between the chain links and guide rolls throughout the curved path section, maintaining smooth movement while enabling curved path transport.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The interaction faces of the chain links are given specific curvature parameters that correspond to the guide roll curvature. This parameter optimization minimizes harmful radial forces and polygon effects, allowing the conveyor to handle curved paths reliably.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If friction reduction measures are implemented on curved path sections, then movement efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvemovement efficiencyVSAvoidcurved path mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

By curving the interaction faces of the chain links to match the guide rolls, the design reduces friction and polygon effects through geometric optimization rather than adding complex mechanical components. This maintains movement efficiency while avoiding increased device complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The curvature parameters of the chain link faces are optimized to minimize friction and radial forces on curved paths. This parameter-based solution improves productivity through efficient geometry rather than through additional complex mechanisms.

Inventive Principle:
Principle #35Parameter changes
