Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing conveyor systems struggle to maintain consistent spacing of objects of varying sizes, especially irregular shapes like envelopes and bags, which complicates downstream processing such as sorting and diverting.

Innovation Solution

A conveyor system with expandable flights that can adjust spacing dynamically by using a linkage mechanism and a linear transport system, allowing each flight to expand or collapse independently to accommodate objects of different sizes and shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed spacing flights are used on a conveyor, then the structure is simple and reliable, but the spacing cannot be adjusted for objects of varying sizes and shapes

Engineering Contradiction:

Improveadaptability to objects of varying sizesVSAvoidcomplexity of flight structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flight is designed with movable panels connected by a linkage mechanism that allows the flight to dynamically adjust its spacing. The panels can move between different positions to create variable spacing intervals, enabling the same flight structure to accommodate objects of different sizes and shapes while maintaining a relatively simple overall design.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If variable spacing is implemented to accommodate different package sizes, then adaptability improves, but the complexity of the spacing mechanism increases

Engineering Contradiction:

Improvespacing adjustment capabilityVSAvoidcomplexity of linkage mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flight is divided into multiple discrete panels that can be independently positioned relative to each other. These segmented panels are connected through a linkage mechanism that allows each panel to be adjusted to create the desired spacing pattern, enabling variable spacing for different package sizes without requiring a completely complex redesign of the entire flight system.

Inventive Principle:

Principle #1Segmentation

3Manufacturing precision

If traditional flights are used, then the device complexity is low, but manufacturing precision and control of object spacing is insufficient

Engineering Contradiction:

Improveprecision of object spacingVSAvoidcomplexity of flight control system

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The flight system incorporates a control mechanism that monitors and adjusts the spacing between panels based on feedback signals. This feedback system enables precise control of object spacing by dynamically adjusting the panel positions through the linkage mechanism, ensuring consistent spacing even as the system adapts to different object sizes and shapes.

Inventive Principle:

Principle #23Feedback

AI summary

A conveying system employs expandable flights for controlling the spacing of objects conveyed by a conveyor. Each flight includes a body portion comprising a pair of panels separated by an expandable linkage system. The flight is pivotally mounted to a mover of a linear transport system via a mounting portion so that the flight can be moved independently of the conveyor.
