Smoking Article Packet Stamp Alignment and Tearing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for smoking articles limits the free positioning of stamps, leading to alignment issues and unpleasant effects during removal, as the stamp is typically fixed in conjunction with the tear tape, restricting its placement and making correct alignment difficult.
Innovation Solution
A packet design where the stamp is fixed to the container with a free portion and a tearing element arranged between the container and the stamp, ensuring the stamp tears when the wrapping is removed, while maintaining alignment and appearance, using a weakening line and tear tape to facilitate clean tearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stamp is fixed to the wrapping material and then the container is wrapped, then the stamp can be torn during removal, but the positioning of the stamp is limited and alignment is difficult
Solution Approach 1:
The stamp is divided into two functional parts: a fixed portion attached to the container and a free portion extending toward the wrapping material. This segmentation allows the stamp to remain properly aligned on the container while still being able to tear during wrapping removal, resolving the contradiction between reliability of tearing function and manufacturing precision of alignment.
Solution Approach 2:
The free portion of the stamp acts as an intermediary element between the container and the wrapping material. It extends from the container surface toward the wrapping material, enabling the stamp to be torn during removal without requiring the entire stamp to be fixed to the wrapping, thus maintaining both alignment precision and tearing reliability.
2Manufacturing precision
If the stamp is fixed to the container with limited positioning, then alignment is easier, but the stamp cannot be freely positioned and aesthetic appearance is compromised
Solution Approach 1:
By segmenting the stamp into a fixed portion and a free portion, the invention enables free positioning of the stamp on the container while maintaining aesthetic appearance. The fixed portion ensures proper alignment during manufacturing, while the free portion can extend to visually pleasing locations without compromising positioning precision.
3Ease of operation
If the tear tape is used to remove the wrapping, then the wrapping can be easily removed, but the stamp alignment is restricted to the tear tape position
Solution Approach 1:
The free portion of the stamp serves as an intermediary that extends beyond the tear tape position, allowing the stamp to be positioned freely on the container while still being torn during wrapping removal. This resolves the restriction imposed by tying stamp position to tear tape location, maintaining both ease of operation and positioning freedom.
