Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for producing and packaging bags, such as plastic bags, result in inconvenient separation, inefficient use of storage and presentation space, and time-consuming information provision, especially when bags are rolled and require manual tearing or welding.
Innovation Solution
A method involving tubular or semi-tubular material formation with weld seams, formatting folds, and angular geometry to create stacks that can be easily stored and presented, allowing for individual bag removal with minimal effort, and incorporating a safety device for secure transport and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bags are wound up on a roll for storage and distribution, then the bags can be easily transported and stored, but the user has to manually separate the bags by tearing or welding, which is inconvenient and time-consuming
Solution Approach 1:
The continuous roll of bags is segmented into individual bags through pre-cut separations and formatting folds. Each bag is divided into a usable portion and a remaining portion that stays connected to the roll, enabling easy separation without manual tearing or welding.
Solution Approach 2:
The bags are pre-formatted with folds and pre-cut separations during manufacturing, so that when a user pulls a bag from the roll, it separates cleanly without requiring additional manual separation actions. The formatting fold and perforation are prepared in advance to facilitate easy separation.
2Ease of manufacture
If bags are wound on a roll, then storage and transport are simplified, but the packaging space cannot be optimally utilized and information provision becomes time-consuming
Solution Approach 1:
The roll is divided into multiple individual bags with defined separations, allowing the packaged product to be compactly arranged in an angular container that optimizes storage space utilization while maintaining easy access to individual bags.
Solution Approach 2:
The invention transitions from a two-dimensional roll format to a three-dimensional angular stack configuration. The bags are folded and stacked in an angular geometry that maximizes space utilization in the container while allowing efficient storage and presentation.
3Productivity
If bags are connected via perforation or welding on a roll, then continuous production is achieved, but the bags can be damaged or destroyed during separation by the user
Solution Approach 1:
The continuous roll is segmented into individual bags with pre-defined separation points using formatting folds and perforations. This segmentation allows clean separation without damaging the bag structure, as each bag is pre-formed with its own defined boundaries.
Solution Approach 2:
The bags are pre-formatted with folds and perforations during manufacturing, so that separation occurs along predetermined safe lines that do not compromise bag integrity. The formatting fold creates a natural separation point that prevents damage during user separation.
4Ease of operation
If a roll format is used for bag distribution, then handling is simplified, but large areas are unavailable for consumer information and product details
Solution Approach 1:
The invention transitions from a two-dimensional roll surface to a three-dimensional angular container with multiple visible faces. This angular geometry provides large surface areas on multiple sides of the container that can be used for displaying consumer information and product details while maintaining easy handling.
