Solution Overview

Problem

Continuous conveyor systems require significant space, limiting their compactness and increasing maintenance and safety challenges due to the need for accessible paths and escape routes, while existing solutions struggle to balance space efficiency with maintenance and safety considerations.

Innovation Solution

A continuous conveyor system with a height-adjustable middle conveyor segment that allows for the creation of a free passage below the conveyor device, enabling space optimization and maintaining accessibility for maintenance, repairs, and emergency routes through mechanical height adjustment, ensuring sufficient clearance for personnel to pass underneath without compromising object conveyance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the conveyor system is made more compact to reduce space requirements, then space efficiency is improved, but accessibility for maintenance and safety becomes more difficult

Engineering Contradiction:
Improvespace requirementVSAvoidaccessibility for maintenance
Core Design Contradiction:
Area of stationary objectVSEase of repair

Solution Approach 1:

The middle conveying segment is designed with height adjustability, allowing it to dynamically change position between a lowered state (for maintenance access) and a raised state (for compact operation). This dynamic adjustment resolves the contradiction by enabling the system to adapt its configuration based on operational needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The conveyor system is divided into separate conveying segments, with the middle segment being independently height-adjustable. This segmentation allows the middle segment to be raised or lowered independently, providing maintenance access without affecting the overall compactness of the integrated system.

Inventive Principle:
Principle #1Segmentation

2Productivity

If pedestrian walkway space is reduced to optimize conveyor compactness, then productivity is improved, but escape routes and maintenance access are compromised

Engineering Contradiction:
Improveconveyor compactnessVSAvoidescape route availability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The middle conveying segment's height can be dynamically adjusted to create clearance for escape routes when needed. During normal operation, the segment remains in the raised position for compactness, but can be lowered to provide safe passage, thus maintaining both productivity and safety requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The vertical position parameter of the middle conveying segment is changed to create different operational modes: raised position for compact operation and lowered position for creating escape routes. This parameter change allows the system to meet both compactness and safety requirements at different times.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the conveying system is raised to create passage space, then accessibility is improved, but object conveyance may be interrupted

Engineering Contradiction:
Improvepassage accessibilityVSAvoidobject conveyance continuity
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The conveyor is segmented into front, middle, and rear sections. When the middle segment is raised to create passage space, the front and rear segments can continue conveying objects independently, maintaining productivity while providing accessibility. The segmentation allows partial operation during maintenance access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The middle conveying segment periodically adjusts its height between raised and lowered positions based on operational requirements. During normal operation, it remains raised for compactness; when passage is needed, it temporarily lowers, creating periodic cycles that balance accessibility and continuous conveyance.

Inventive Principle:
Principle #19Periodic action
