Solution Overview

Problem

Automated tax stamp application machines struggle to accurately position tax stamps on non-standard sized packs, particularly those used for electronic aerosol-generating devices, as they require machine adaptations that are difficult to implement remotely near the point of sale.

Innovation Solution

A method involving the simultaneous supply and vertical and horizontal spacing of pairs of packs using space bars in a transport device, with pack spacers and pair spacers in the package to maintain consistent positioning, allowing for efficient and automated filling of packages, reducing manual handling and misalignment risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional tax stamp application machines are used for non-standard sized packs, then the existing machine infrastructure can be utilized, but the machines cannot accurately position tax stamps on packs with different sizes without adaptation

Engineering Contradiction:

Improvepack size compatibilityVSAvoidtax stamp positioning accuracy

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The pack handling process is segmented into standardized units (pairs of packs) with fixed spacing requirements. By dividing the problem into standardized segments with defined geometric relationships, the system can handle various pack sizes through consistent spacing rather than size-specific adjustments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system changes the parameter being controlled from pack size to spacing distance. Instead of adapting to different pack dimensions, the invention maintains constant vertical and horizontal spacing between packs, allowing the same machine configuration to handle diverse pack sizes while preserving positioning accuracy.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If machine adaptations are implemented to handle non-standard pack sizes, then tax stamp positioning accuracy can be maintained, but the complexity and cost of machine adaptation increases

Engineering Contradiction:

Improvetax stamp positioning accuracyVSAvoidmachine adaptation complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The spacing between packs is predetermined and established during the pack assembly stage, before the tax stamp application process. Space bars and spacers are pre-positioned to create consistent geometric relationships, eliminating the need for complex real-time adjustments during tax stamp application.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Space bars and spacers serve as intermediary elements that mediate between packs of different sizes and the tax stamp application machine. These intermediaries enforce consistent spacing relationships, allowing the machine to operate with fixed geometry while handling variable pack sizes.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If manual handling of packs is used to accommodate different sizes, then flexibility in handling various pack formats is achieved, but misalignment and handling time increase

Engineering Contradiction:

Improvepack format flexibilityVSAvoidhandling time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The pack handling system is designed to be self-adjusting through the use of space bars and spacers that automatically maintain proper spacing and alignment. The geometry of the handling apparatus itself enforces correct positioning, eliminating the need for manual adjustment while maintaining flexibility for different pack sizes.

Inventive Principle:

Principle #25Self-service

4Manufacturing precision

If individual packs are handled and positioned separately, then precise positioning can be achieved, but the filling speed and efficiency decrease

Engineering Contradiction:

Improvepack positioning precisionVSAvoidpackage filling speed

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

Pairs of packs are handled and positioned together as a single unit with fixed vertical and horizontal spacing. By merging the handling of two packs into one operational unit, the system achieves both precision (through consistent spacing) and efficiency (through reduced handling operations).

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method for filling a package with a group of pairs of packs, comprising supplying a group of pairs of packs simultaneously from a transport device to a package, vertically spacing the two packs of each pair of packs of the group of pairs of packs from each other in the package, and horizontally spacing each pair of packs from each other in the package. The method further comprises maintaining a horizontal spacing between each pair of packs of the group of pairs of packs while supplying the group of pairs of packs to the package by guiding the pairs of packs of the group of pairs of packs along space bars provided in the transport device.
