Cigarette Pouch Compartment Sealing for Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bags for the cigarette industry with additional compartments risk accidental loss of contents when removing items from the main pocket, as the compartment opening is a mirror image of the main bag opening.
Innovation Solution
The compartment is continuously closed on one side edge with a sealing seam, and another side edge is partially closed with a side sealing seam, featuring an access opening on an unsealed side edge, and can be further secured with closure means like adhesive tape or Velcro, with an optional punching aid for easy opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the compartment opening is made the same as the main bag opening for ease of access, then the ease of operation is improved, but the reliability deteriorates as contents can accidentally enter the compartment
Solution Approach 1:
The bag structure is segmented into distinct access paths: the main bag opening for removing contents and a separate compartment access opening for adding items. This segmentation prevents accidental mixing while maintaining ease of access to both functions through dedicated openings.
Solution Approach 2:
A closure means (such as a flap or latch) acts as an intermediary element between the compartment opening and the interior. This intermediary prevents unintended entry of contents into the compartment while allowing intentional access when needed.
2Reliability
If the compartment is fully sealed to prevent accidental entry, then the reliability is improved, but the ease of operation deteriorates due to difficulty in accessing the compartment
Solution Approach 1:
The compartment has different opening characteristics at different locations: one opening faces the main bag opening (for controlled access) and another opening is positioned at the bottom (for easy item placement). This local differentiation allows reliable sealing while maintaining operational ease through strategically positioned access points.
3Ease of operation
If the compartment opening is positioned at the bottom for easy item placement, then the ease of operation is improved, but the reliability deteriorates as items can accidentally fall into the compartment
Solution Approach 1:
The compartment is designed with a bottom opening that allows easy item placement, but a closure means is preliminarily positioned to prevent accidental entry. The closure can be activated before items are placed or automatically engages to prevent unintended access, thus maintaining both ease of placement and reliability.
