Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional guiderail adjustment systems for conveyors, particularly around arcuate paths, suffer from cable slack buildup, which is problematic and inefficient.

Innovation Solution

A support system for guiderails that uses a pair of pivoting arms connected to shuttles moving along a support rail, allowing for flexible adjustment of the guiderail position without increasing the conveyor's overall width, using manual or automated mechanisms to extend or retract the guiderail.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If cable driven supports are used to adjust guiderail position, then the guiderail can be extended and retracted to accommodate different article sizes, but cable slack builds up particularly around arcuate paths reducing system reliability

Engineering Contradiction:

Improveguiderail position adjustmentVSAvoidcable slack buildup

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the cable from the support mechanism entirely, replacing it with a rigid support rail that extends along the arcuate portion of the conveying path. The support rail directly guides the support structure without using cables, thereby eliminating cable slack buildup while maintaining the ability to adjust guiderail position.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The support rail is specifically designed to follow the arcuate curvature of the conveying path. By matching the curvature of the rail to the arcuate section, the system maintains proper guiderail alignment throughout the curved portion without cable slack issues that plagues straight cable-driven systems on curved paths.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If conventional cable driven adjustment systems are used, then guiderail position can be changed, but the system complexity increases due to cable management requirements

Engineering Contradiction:

Improveguiderail adjustment capabilityVSAvoidcable driven mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable-driven mechanism is completely removed and replaced with a simpler rigid support rail structure. The support rail provides direct mechanical guidance for the support, eliminating all cable management complexity including tensioning, routing, and slack prevention that would otherwise be required.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The support rail is positioned specifically along the arcuate portion where adjustment is needed, rather than using a complex cable system throughout the entire conveyor. This localized rigid guidance provides the necessary adjustment capability only where required, simplifying the overall system.

Inventive Principle:

Principle #3Local quality
