Solution Overview

Problem

Conveyor chain links with thrust bodies connected via swiveling connections face challenges in accumulating holding adapters, leading to issues in transporting objects like bags and clothing without causing wrinkles or mechanical friction.

Innovation Solution

The chain link features a vertically elastic connection between the pusher body and the base body using spring elements, allowing the pusher body to be easily lifted when adapters accumulate, reducing friction and preventing wrinkles, with spring elements designed as spring leaves at an angle between 5° and 30° for efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If thrust bodies are rigidly connected to chain links, then pushing force is strong, but holding adapters cannot be accumulated and items become wrinkled

Engineering Contradiction:
Improvetransportation reliabilityVSAvoidaccumulation capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The thrust body is connected to the chain link via a spring element instead of a rigid connection, making the system dynamic. The spring element allows the thrust body to move vertically relative to the chain link, enabling adaptation to accumulation conditions while maintaining pushing capability during transport.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring element changes the vertical position parameter of the thrust body based on operational conditions. During transport, the spring maintains the thrust body in a position that provides strong pushing force; during accumulation, the spring allows the thrust body to move upward, reducing friction and enabling smooth accumulation.

Inventive Principle:
Principle #35Parameter changes

2Force

If thrust bodies are rigidly connected to chain links, then pushing force is strong, but friction increases and items become wrinkled

Engineering Contradiction:
Improvepushing forceVSAvoidfriction and wrinkles
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The spring element creates a dynamic connection that adjusts the thrust body's position. During accumulation, the spring allows upward movement of the thrust body, reducing contact friction with the holding adapter and preventing wrinkles on transported items.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring element acts as a cushioning element that absorbs and reduces the impact and friction forces between the thrust body and the holding adapter during accumulation, preventing damage and wrinkles to the transported items.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Adaptability or versatility

If spring elements are used for elastic connection, then accumulation is enabled, but device complexity increases

Engineering Contradiction:
Improveaccumulation capabilityVSAvoidchain link structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The spring element is integrated directly into the chain link structure, merging the elastic connection function with the existing chain link design. This integration minimizes additional components and simplifies the overall structure while enabling accumulation capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spring element functions as a flexible component that provides the necessary elastic connection. By using a spring element that can be integrated into the chain link, the design achieves accumulation capability without significantly increasing device complexity.

Inventive Principle:
Principle #30Flexible shells and thin films

4Ease of operation

If spring elements connect thrust body to base body, then detachment is easier, but connection strength may be reduced

Engineering Contradiction:
Improvedetachment easeVSAvoidconnection strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The spring element provides a dynamic connection that is strong during transport (when the thrust body is pressed against the holding adapter) and allows easy detachment during accumulation (when the spring permits upward movement). The dynamic nature of the spring connection satisfies both requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring element is pre-configured to provide sufficient connection strength during transport while inherently allowing detachment when accumulation forces are applied. This preliminary design ensures both strong connection and easy detachment without requiring additional mechanisms.

Inventive Principle:
Principle #10Preliminary action
