Solution Overview

Problem

Existing chain conveyors are ergonomically challenging for users of different heights and lack the ability to adjust height during operation, leading to muscle strain and inefficiencies in handling workpieces of varying sizes, and they cannot interrupt the circulation of workpieces without risking damage.

Innovation Solution

A height-adjustable chain conveyor system with C-shaped guide rail elements and sub-segments that can rotate and longitudinally displace, allowing dynamic height adjustment and ensuring the conveyor chain remains securely guided, enabling ergonomic loading and unloading and accommodating different user heights.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the chain conveyor operates at a fixed height, then the structure is simple and stable, but it causes muscle strain for users of different heights and prevents ergonomic loading/unloading

Engineering Contradiction:
Improveergonomic loading and unloadingVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The guide rail is designed with height-adjustable sections that can be dynamically repositioned during operation. The guide rail comprises multiple guide rail elements that can be individually adjusted to different heights, allowing the conveyor chain to operate at variable heights without requiring complete system shutdown or complex reconstruction of the entire conveyor structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide rail is divided into multiple independent guide rail elements that can be individually adjusted. Each guide rail element can be positioned at different heights relative to the floor area, allowing selective height adjustment of specific sections while maintaining the overall structural integrity and simplicity of the conveyor system.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the chain conveyor height is adjusted during operation, then ergonomic handling is improved, but the guide chain may become unguided or damaged

Engineering Contradiction:
Improveheight adjustment capabilityVSAvoidchain guidance stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The guide rail elements are designed to be dynamically adjustable during conveyor operation. The height adjustment mechanism allows guide rail elements to be repositioned while the conveyor chain continues to circulate, ensuring that the chain remains properly guided throughout the adjustment process without risk of damage or misalignment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system enables continuous operation with variable height parameters. The guide rail elements can be adjusted to different vertical positions while maintaining proper chain guidance, allowing the conveyor to adapt to different workpiece sizes and user heights without compromising chain stability or requiring interruption of circulation.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the conveyor chain is interrupted for height adjustment, then ergonomic positioning is achieved, but productivity and continuous processing are reduced

Engineering Contradiction:
Improveergonomic positioningVSAvoidcontinuous circulation
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The height adjustment mechanism is designed to operate during continuous conveyor circulation. Guide rail elements can be repositioned vertically while the conveyor chain continues to move and transport workpieces, eliminating the need to interrupt production or halt the drying/processing operations in progress.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system maintains continuous useful action by allowing height adjustments without interrupting the conveyor chain circulation. Workpieces continue to be transported through processing stations, and the guide rail adjustments occur in a manner that does not disrupt the ongoing productive operations.

Inventive Principle:
Principle #20Continuity of useful action

4Adaptability or versatility

If a U-shaped section is used for length compensation during height adjustment, then height variability is achieved, but the device occupies large area and loses compactness

Engineering Contradiction:
Improveheight variabilityVSAvoidoccupancy area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The guide rail is segmented into multiple adjustable elements that can be independently positioned at different heights. This segmentation allows vertical height adjustment without requiring horizontal space for U-shaped compensation sections, maintaining compact footprint while achieving the desired height variability for different workpiece sizes and user ergonomics.

Inventive Principle:
Principle #1Segmentation
