Solution Overview

Problem

High-speed packaging machines pose a risk of damaging delicate food products like biscuits due to the high dynamics and rapid movements of grouping elements, which can cause stress on both the actuators and the products.

Innovation Solution

An apparatus with a grouping device featuring two independently movable grouping elements that cyclically reverse their positions to form groups of products in contact with each other, reducing high-speed impacts and allowing for controlled speed adjustments to prevent product damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single grouping element moves cyclically downstream and upstream of each group of products to slow down and accelerate the products, then the products can be grouped together, but the high speeds and accelerations cause stress on the actuators and risk of damaging the products

Engineering Contradiction:
Improvegrouping speedVSAvoidproduct damage risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The single grouping element is divided into two separate grouping elements (first grouping element and second grouping element) that move independently. Each element handles one end of the product group, allowing synchronized movement without requiring high speeds or accelerations. This segmentation reduces the harmful dynamic forces while maintaining grouping functionality.

Inventive Principle:
Principle #1Segmentation

2Productivity

If a single grouping element moves cyclically downstream and upstream of each group of products to slow down and accelerate the products, then the products can be grouped together, but the high speeds and accelerations cause stress on the actuators

Engineering Contradiction:
Improvegrouping speedVSAvoidactuator stress
Core Design Contradiction:
ProductivityVSStress or pressure

Solution Approach 1:

The single grouping element is divided into two separate grouping elements (first grouping element and second grouping element) that move independently. Each element handles one end of the product group, allowing synchronized movement without requiring high speeds or accelerations. This segmentation reduces the harmful dynamic forces while maintaining grouping functionality.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the grouping element moves cyclically downstream and upstream of each group of products, then the products can be grouped together, but the high-speed impact may damage delicate food products

Engineering Contradiction:
Improvepackaging speedVSAvoidproduct integrity
Core Design Contradiction:
ProductivityVSStrength

Solution Approach 1:

The single grouping element is divided into two separate grouping elements (first grouping element and second grouping element) that move independently. Each element handles one end of the product group, allowing synchronized movement without requiring high speeds or accelerations. This segmentation reduces the harmful dynamic forces while maintaining grouping functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The two grouping elements move in a coordinated manner that prevents high-speed impacts before they can occur. By distributing the grouping function across two elements moving independently, the system cushioning effect is achieved through reduced dynamic forces, protecting delicate products like biscuits from damage while maintaining packaging speed.

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