Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Pre-filled piping bags with a male part of a piping nozzle inserted during filling often result in the nozzle being placed incorrectly or in an undesired orientation, leading to time-consuming adjustments and a risk of the bag tearing.

Innovation Solution

A method and device using a piping nozzle applicator to position the nozzle at a substantial distance from the desired location within the bag, then moving it securely into place using friction or expandable parts to ensure correct orientation and positioning before filling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a male part of a piping nozzle is inserted into the piping bag during filling, then the piping bag can be pre-filled and sealed, but the nozzle may end up in the wrong place or wrong orientation

Engineering Contradiction:

Improvepre-filled piping bag productionVSAvoidnozzle position and orientation

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The piping nozzle is inserted into the piping bag before the filling process begins. The male part of the nozzle is placed in the bag, and then the bag is filled with pipeable substance through a separate filling opening. This preliminary positioning ensures the nozzle remains in the correct location and orientation throughout the filling and sealing process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A guide structure or positioning mechanism acts as an intermediary between the nozzle insertion process and the final positioned state. This intermediary structure ensures the nozzle is correctly oriented and positioned during insertion, preventing misalignment while allowing pre-filled bag production.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the piping nozzle is inserted through a small hole at the tip of the piping bag, then the nozzle is locked in place, but the bag must be empty for smooth insertion

Engineering Contradiction:

Improvenozzle locking in placeVSAvoidbag filling status

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The piping bag is divided into two separate openings: a filling opening for inserting the pipeable substance and a tip opening for inserting and locking the piping nozzle. This segmentation allows the bag to be filled with substance while the nozzle is inserted through the tip, enabling both functions to occur independently without interference.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The piping nozzle is inserted into the piping bag before the filling process begins. The male part of the nozzle is placed in the bag through the tip opening, and then the bag is filled with pipeable substance through the filling opening. This preliminary positioning ensures the nozzle remains in the correct location and orientation throughout the filling and sealing process.

Inventive Principle:

Principle #10Preliminary action

3Ease of manufacture

If the piping nozzle is inserted during filling, then pre-filled piping bags can be produced, but user manipulation may cause the bag to tear or split

Engineering Contradiction:

Improvepre-filled piping bag productionVSAvoidbag tearing or splitting

Core Design Contradiction:

Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A positioning feedback mechanism ensures the piping nozzle is correctly positioned and oriented before the filling process begins. This feedback system verifies proper nozzle placement, preventing misalignment that could lead to bag tearing or splitting during subsequent handling and use.

Inventive Principle:

Principle #23Feedback

AI summary

A method for fitting a piping nozzle (1) or a part of a piping nozzle (1) in a piping bag (2) comprises placing the piping nozzle (1) in an initial position (3), which initial position (3) is situated at a substantial distance from a piping position (5) located in the piping bag (2), using a piping nozzle applicator (4), which is movable between the initial position (3) and the piping position (5), to releasably engage with the piping nozzle (1) at the initial position (3), using the piping nozzle applicator (4) to bring the piping nozzle (1) from the initial position (3) substantially to the piping position (5) in the piping bag (2), releasing the piping nozzle (1) from the piping nozzle applicator (4) at the piping position (5), and pulling the piping nozzle applicator (4) back from the piping position (5).
