Solution Overview

Problem

Cigarette pack opening tabs with adhesive-free grip tabs are difficult for consumers to grasp and operate effectively, as they often require manual manipulation and are not easily positioned for easy handling.

Innovation Solution

The grip tab is mechanically processed or treated with compressed air, radiation, or moisture to position it at an acute angle, making it easier to attach and use, and can be folded or deformed to create a stable functional position during the manufacturing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the grip tab is left flat and unprocessed on the opening tab, then the manufacturing process is simple, but the grip tab is difficult for consumers to grasp and operate effectively

Engineering Contradiction:
Improveease of grasping grip tabVSAvoidcomplexity of grip tab processing
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The grip tab is pre-positioned at an acute angle to the opening tab during the manufacturing process, before the pack reaches the consumer. This preliminary positioning action ensures that when the consumer receives the pack, the grip tab is already in an optimal grasping position, eliminating the need for additional manual manipulation while maintaining manufacturing simplicity through integrated processing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The grip tab undergoes parameter changes in its spatial orientation during manufacturing, transitioning from a flat position to an acute angle position relative to the opening tab. This parameter change in angular position is achieved through mechanical processing or treatment with compressed air, radiation, or moisture during the manufacturing process, making it easier to grasp without significantly increasing device complexity.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the grip tab is processed mechanically or with compressed air to position it at an acute angle, then it becomes easier to grasp, but the manufacturing process becomes more complex

Engineering Contradiction:
Improveease of grasping grip tabVSAvoidease of manufacturing process
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The system uses the existing manufacturing process infrastructure to automatically position the grip tab at an acute angle without requiring separate manual intervention. The grip tab positioning is integrated into the existing production line, where mechanical processing or compressed air treatment is applied as part of the normal manufacturing sequence, allowing the process to serve itself rather than requiring additional complex equipment or steps.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If the grip tab is folded into a 180° position and fixed by pressure elements, then it achieves a stable functional position, but the manufacturing process requires additional processing steps

Engineering Contradiction:
Improvestability of grip tab positionVSAvoidcomplexity of folding and fixing mechanism
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The grip tab is pre-folded into a 180° position and pre-fixed with pressure elements during the manufacturing process, before the pack is assembled and distributed. This preliminary folding and fixing action ensures that the grip tab maintains a stable functional position throughout the product lifecycle, while the complexity of the folding mechanism is integrated into the manufacturing equipment rather than requiring additional components in the final product.

Inventive Principle:
Principle #10Preliminary action

4Ease of operation

If the coating on the grip tab is exposed to heat or moisture to cause deformation, then the grip tab becomes curved and easier to grasp, but additional processing equipment is required

Engineering Contradiction:
Improveease of grasping curved grip tabVSAvoidcomplexity of heat or moisture treatment system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces mechanical folding or positioning systems with non-contact methods such as heat or moisture treatment to achieve grip tab deformation. Instead of using complex mechanical arms or pressing mechanisms to fold the grip tab, the system uses thermal or moisture fields to cause the coating to expand or contract, naturally curving the grip tab into an ergonomic shape. This substitution reduces mechanical complexity while achieving the desired functional form.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The invention relates to the production of (cigarette) packs with an inner casing or inner pack which has an opening aid with an openings tab (10) and a gripping tab (23). The gripping tab (23) is to be treated such that the gripping tab permanently remains in a user-friendly position when the pack has been produced, in particular in a lightly inclined position. For this purpose, the gripping tab (23) is lifted from the plane of a (film) web (25) by guide elements or deflectors (46), folded, in particular by up to 180°, stabilized in this position, and then folded back. The gripping tab (23) is gripped preferably in the region of a deflection (45) of the web (25).
