Solution Overview

Problem

Conveyor belt links currently cause unwanted stress and oscillation in conveyed products due to torque generated during interaction with driving means, leading to instability and potential damage, especially when handling small products.

Innovation Solution

A side chain link with a C-shaped lateral tab instead of a cantilevered flap, reducing torque and oscillation, and a V-shaped body design allowing for easier assembly and use with smaller guiding wheels, enabling smooth motion transmission and improved product integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cantilevered lateral tab is used in known links, then the link can be driven by toothed wheels, but torque is generated causing oscillation and stress on conveyed products

Engineering Contradiction:
Improveproduct stabilityVSAvoidoscillation and stress on products
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the traditional cantilevered tab design by using a C-shaped tab that extends through the link body. This inversion changes the mechanical interaction with the toothed wheel, allowing the tab to engage and disengage more smoothly without generating harmful torque oscillations that affect product stability

Inventive Principle:
Principle #13The other way round (Inversion)

2Object-affected harmful factors

If a C-shaped lateral tab is used instead of a cantilevered flap, then torque and oscillation are reduced, but the tab structure becomes more complex

Engineering Contradiction:
Improvetorque and oscillationVSAvoidtab structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The C-shaped tab is integrated directly into the link body as a unified structure rather than being a separate component. This merging of the tab with the link body achieves the desired reduction in torque and oscillation while avoiding the complexity of additional separate parts, assemblies, or fastening mechanisms

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If smaller guiding wheels are used, then transfer quality of small products is improved, but the driving mechanism becomes less stable

Engineering Contradiction:
Improvetransfer quality of small productsVSAvoiddriving mechanism stability
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent changes the geometric parameters of the C-shaped tab, specifically its height and thickness, to optimize the interaction with smaller guiding wheels. This parameter adjustment allows the use of smaller wheels that improve transfer quality for small products while maintaining driving mechanism stability through the optimized tab dimensions

Inventive Principle:
Principle #35Parameter changes

AI summary

A link (10) of a side chain for conveyor belts, particularly for food, of the type comprising a substantially V-shaped body (11), the rear portion (15) of which has, on each end part (13, 14), a hole (21, 22) for the insertion of an end portion (18a) of a rod-like element (19a); the outer rear end part (13) has a lateral tab (23) that is contoured to mesh with a wheel or belt provided with teeth (24) of associated driving means. The lateral tab (23) is formed so as to be crossed by the axis of the holes (25) for the rod-like element (19a).
