Bag Knot Structure With Pre-Configured Wire Loops
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag knot structures require multiple steps to close the inlet, lacking a convenient one-touch method for sealing.
Innovation Solution
A bag knot structure featuring a two-layer bag body with strategically placed holes and a knotting wire that forms loops and a grip to securely close the inlet with a single touch by passing the wire through specific holes, creating a knotting mechanism that allows for easy closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional bag inlet closure method is used, then the inlet can be closed, but multiple steps are required and it is not convenient to close
Solution Approach 1:
The knotting wire is pre-configured with loops and gripping portions at specific positions before use. The wire is arranged to pass through designated holes in the bag body, with loops formed at strategic locations and a gripping portion created at the end. This preliminary arrangement enables one-touch closure without requiring complex manual knot-tying steps during the actual closing operation.
2Reliability
If a simple closure method is used, then the operation is quick, but the closure may not be secure
Solution Approach 1:
The closure mechanism is divided into multiple functional segments: a knotting wire with distinct loops and gripping portions, multiple holes positioned at different locations on the bag body, and specific routing paths for the wire. Each segment serves a particular function - loops provide anchoring points, the gripping portion provides manual engagement, and the hole positions ensure proper wire routing. This segmentation allows the system to achieve secure closure through a simple one-touch operation.

AI summary
Provided is a bag knot structure including: a bag body part (10) formed in two layers, and configured to have closed three sides and have an open inlet; a first hole (21) located on one side of the top of the bag body part (10) and in proximity to the inlet, and formed through the bag body part (10); a second hole (22) located in proximity to the first hole (21), and formed through the bag body part (10); a third hole (23) spaced apart from the second hole (22), located on the other side of the top, and formed through the bag body part (10); and a knotting wire (30) disposed on the back surface of the bag body part (10); wherein parts of the knotting wire (30) are caused to form a first loop (31), a second loop (32), and a grip (34).
