Solution Overview

Problem

Climbing sorters often experience issues with objects slipping and becoming trapped between load-carrying devices, leading to damage and blockages, especially during transitions between different rail sections.

Innovation Solution

A flexible intermediate cover is arranged between load-carrying devices, forming a stair structure in rising and falling sections, which sags in flat sections and stretches in inclined sections to prevent objects from becoming trapped by pushing them onto downstream load-carrying devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If objects are transported on load-handling devices through ascending sections, then transportation efficiency is improved, but objects can slip and become trapped between devices causing damage and blockages

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidobject safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

A flexible intermediate cover is introduced as a mediator element between adjacent load-handling devices. This cover prevents objects from slipping into gaps between devices during ascending transport, eliminating the harmful effect while maintaining transportation functionality. The cover is attached to both devices and forms a protective barrier that guides objects safely.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The intermediate cover is made of flexible material that can adapt to the movement and positioning of load-handling devices. This flexibility allows the cover to maintain its protective function while accommodating the dynamic nature of the sorting system, preventing objects from becoming trapped without interfering with normal operations.

Inventive Principle:
Principle #30Flexible shells and thin films

2Quantity of substance

If load-handling devices are positioned close together to increase capacity, then transportation capacity is improved, but objects can become trapped in the gaps between devices

Engineering Contradiction:
Improvetransportation capacityVSAvoidobject trapping
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The flexible intermediate cover serves as a mediator that fills the gap between closely positioned load-handling devices. It allows the devices to be positioned close together for increased capacity while preventing objects from entering the gaps, thus eliminating the harmful trapping effect.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the guide rail has ascending and sloping sections for vertical transport, then sorting versatility is improved, but objects can slip and be crushed during slope transitions

Engineering Contradiction:
Improvesorting versatilityVSAvoidobject crushing
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The flexible intermediate cover acts as a protective mediator during slope transitions. It prevents objects from slipping off load-handling devices and being crushed by subsequent devices, while allowing the guide rail to maintain its ascending and sloping sections for versatile sorting operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution ensures safe transportation of objects by preventing them from slipping between load-carrying devices and getting crushed, maintaining the flow of objects through the sorter even during changes in rail slope.
