Solution Overview

Problem

Existing sorting systems lack flexibility in article discharge and sorting capacity, as they are limited to discharging articles only on one side of the output conveyor and have fixed discharge locations.

Innovation Solution

The sorting system incorporates output displacing members, such as cross-belts or trays with movable pushing elements, allowing articles to be discharged from both sides of the output conveyor and providing flexible discharge locations, enhancing sorting capacity and efficiency by synchronizing the movement of input and output displacing members to minimize friction and facilitate smooth article transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If articles are discharged only on one side of the output conveyor, then the discharge mechanism is simple, but the sorting capacity and flexibility are limited

Engineering Contradiction:
Improvesorting capacityVSAvoiddischarge mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The output conveyor is divided into multiple discharge locations on both sides, with each carrier capable of discharging articles at different sides. This segmentation allows the system to handle multiple destinations simultaneously, doubling the effective sorting capacity without requiring a completely separate conveyor for each destination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The output supporting surfaces are made tiltable and movable, allowing dynamic adjustment of discharge locations. Carriers can selectively tilt their supporting surfaces to discharge articles at different sides and locations, providing flexibility in routing articles to various destinations based on real-time sorting requirements.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the input supporting surface and output supporting surfaces form a common supporting surface at the transfer region, then article transfer is smooth with reduced friction, but the system lacks flexibility in locating discharge points

Engineering Contradiction:
Improvearticle transfer smoothnessVSAvoiddischarge location flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The output supporting surfaces are designed to be tiltable and movable relative to the input supporting surface. At the transfer region, they form a common supporting surface for smooth article transfer, but afterward, they can be selectively tilted to different positions to discharge articles at various locations, thus achieving both smooth transfer and flexible discharge.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The output supporting surfaces undergo periodic movement between the transfer position (forming common surface) and the discharge positions (tilted to different locations). This periodic action allows the system to alternate between ensuring smooth transfer and providing flexible discharge options at different destinations.

Inventive Principle:
Principle #19Periodic action

3Productivity

If cross-belts are used as output displacing members, then article transfer efficiency is improved with synchronized movement, but the system complexity increases

Engineering Contradiction:
Improvearticle transfer efficiencyVSAvoidconveyor system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cross-belts are integrated with the carriers to form a combined output conveyor system. The cross-belts and carriers work together as a unified mechanism, with cross-belts providing the displacing action and carriers providing the supporting and tilting function, thereby improving transfer efficiency without requiring entirely separate systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cross-belts serve multiple functions: they act as output displacing members to transfer articles, work in synchronization with input displacing members to minimize friction, and are integrated with the tiltable carrier system to enable flexible discharge. This multi-functionality improves efficiency while avoiding the need for additional dedicated components.

Inventive Principle:
Principle #6Universality (Multi-functionality)
