Bag Closing Device With Protrusions And Drawstring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for closing bags, such as tying knots, are often insufficient, prone to failure, and may not be permissible for individuals observing certain religious observances like Shabbat.
Innovation Solution
A bag closing device with upper and lower surfaces and a peripheral surface featuring multiple openings and sets of protrusions that retain a portion of the bag, allowing it to be closed and carried without tying a knot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a knot is tied to close the bag, then the bag can be closed, but the knot may come undone or the bag edges may rip
Solution Approach 1:
The patent introduces a drawstring as an intermediary element between the user's action and the bag closure. The drawstring passes through the bag opening and, when pulled, cinches the bag closed through a drawing action rather than requiring a knot. This intermediary mechanism transforms the closing action from knot-tying to pulling, eliminating the reliability issues of knots while maintaining ease of operation.
2Reliability
If a permanent knot is tied to securely close the bag, then the bag closure is reliable, but it is not permissible during Shabbat observance
Solution Approach 1:
The patent changes the fundamental parameter of the closing mechanism from permanent (knot) to temporary/reversible (drawstring). The drawstring allows the bag to be closed securely without forming a permanent knot, making it compatible with Shabbat observance while maintaining closure reliability. The closing action is achieved through the drawing motion of the string rather than knot-tying, satisfying both reliability and religious observance requirements.
3Adaptability or versatility
If a loose temporary knot is used to close the bag during Shabbat, then religious observance is maintained, but leakage or odors may occur
Solution Approach 1:
The drawstring acts as an intermediary that enables effective sealing without requiring a knot. By pulling the drawstring, the bag opening is cinched closed through the drawing action, creating a secure seal that prevents leakage and odors. This maintains Shabbat compliance while achieving reliable bag closure, as the sealing effectiveness comes from the drawing mechanism rather than a loose temporary knot.

AI summary
A bag closing device may include an upper surface, a lower surface opposite the upper surface, and a peripheral surface between the upper surface and the lower surface. The peripheral surface may define a first opening and a second opening. The bag closing device may include a first set of protrusions extending into the first opening and a second set of protrusions extending into the second opening.
