Tobacco Pouch Tray Retaining Elements for Corner Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging solutions for bulk tobacco products, such as stand-up pouches and cans, face issues with environmental compatibility and stability, particularly with ziplock closures that can lead to bag corners popping open due to material-related restoring forces.
Innovation Solution
The design incorporates deactivatable retaining elements on the tray's side walls, which initially secure bag corners but can be separated to allow the corners to be folded out, and re-secured using fixing tabs for re-closure, enhancing stability and environmental compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If deactivatable retaining elements are used to secure bag corners, then stability is improved, but device complexity increases
Solution Approach 1:
The retaining elements are designed to be deactivatable, transitioning from a secured state (holding bag corners) to an activated state (releasing bag corners). This dynamic characteristic allows the packaging to adapt to different usage phases: initially providing stability during transport, then allowing easy access when needed.
Solution Approach 2:
The retaining mechanism is divided into multiple independent retaining elements distributed at different locations on the packaging. Each element can be individually deactivated, providing localized control over bag corner retention without requiring complex system-wide changes.
2Ease of operation
If bag corners are folded out for access, then ease of operation is improved, but stability deteriorates
Solution Approach 1:
The retaining elements are pre-positioned and activated during packaging assembly, automatically securing the bag corners in the folded position. This preliminary action eliminates the need for manual intervention to maintain stability during transport and storage.
Solution Approach 2:
The retaining elements act as intermediaries between the bag corners and the packaging structure. They provide a mechanical connection that maintains the folded position of bag corners, facilitating easy access when deactivated while preserving stability when activated.
3Reliability
If multiple retaining elements are used, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The retaining elements utilize material property changes, specifically the deformation and breaking characteristics of the tray material. By designing material weaknesses at specific locations, the retaining elements can be easily deactivated through simple force application, reducing manufacturing complexity while maintaining reliability.
4Ease of operation
If tear-off openings are added for access, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The tear-off openings are designed as sacrificial features that are intentionally created with material weaknesses. These openings are meant to be broken or torn during normal use, and their imprecise nature actually facilitates easy access. The design accepts controlled imperfection as a functional feature rather than a defect.
