Solution Overview

Problem

Conventional dispensing devices for flexible packages are inefficient in removing products completely, often leaving residues, and lack control over opening placement, leading to inaccurate deposition and messy handling, especially with multi-textured foods.

Innovation Solution

A dispensing device with opposing surfaces that compress and move across the package to create an opening, using rollers and a blade to cut and direct the product into a serving receptacle, while maintaining compressive contact to minimize residue and ensure accurate placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If conventional dispensing devices rely on induced package failure to create an opening, then the device structure is simplified, but the opening placement becomes inaccurate and product deposition is imprecise

Engineering Contradiction:
Improvedevice structureVSAvoidopening placement accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The package is pre-formed with a specific weakened area or seam that is designed to fail in a predictable manner. This preliminary preparation allows the package to open at a precise, predetermined location when force is applied, eliminating the need for complex opening mechanisms while maintaining accurate opening placement and product deposition.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If conventional dispensing devices do not include an opening means, then the device structure is simplified, but the device becomes reliant on consistent package manufacture and may not function consistently

Engineering Contradiction:
Improvedevice structureVSAvoidopening consistency
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The package is pre-formed with a specific weakened area or seam that is designed to fail in a predictable manner. This preliminary preparation ensures that the package will open consistently and reliably when force is applied, without requiring complex opening mechanisms or depending entirely on manufacturing consistency.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If conventional dispensing devices lack control over opening placement, then the device structure is simplified, but product placement accuracy deteriorates and debris is deposited within the dispenser

Engineering Contradiction:
Improvedevice structureVSAvoidproduct placement accuracy
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The package is pre-formed with a specific weakened area or seam at a predetermined location. This preliminary preparation ensures that when the package opens, the opening occurs at the exact desired location, allowing accurate product placement into the serving receptacle and preventing debris from being deposited within the dispenser.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If conventional dispensing devices cannot efficiently remove all product from the package, then the device structure is simplified, but product residue increases and waste occurs

Engineering Contradiction:
Improvedevice structureVSAvoidproduct residue
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The dispensing device includes a serving receptacle that extracts and receives the product as it is dispensed from the package. This extraction mechanism ensures that product is efficiently removed from the package and transferred to the receptacle, minimizing residue left in the package and reducing waste.

Inventive Principle:
Principle #2Taking out (Extraction)
