Two-Panel Bag with Tie Handle for Safe Institutional Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bags used in institutional facilities pose safety concerns due to potential weaponization of closing components, and there is a need for cost-effective designs that securely contain objects without using drawstrings, clasps, or connectors.
Innovation Solution
A bag design featuring two identical panels with laterally-inverted shapes connected along edges to form an enclosed interior space, where the top edge is tied to secure the opening, minimizing material waste and allowing for secure object containment without hazardous closure mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional closing structures like drawstrings, clasps, or connectors are used, then the bag can be securely closed, but safety concerns arise as these components can be used as weapons in institutional facilities
Solution Approach 1:
The patent removes traditional closing components (drawstrings, clasps, connectors) that pose safety risks and replaces them with a simple tied closure using only the bag's own fabric. This extracts the harmful elements while maintaining the essential closure function through a safer alternative.
Solution Approach 2:
The invention uses simple, inexpensive fabric ties integrated into the bag structure rather than durable metal or plastic fasteners. These fabric ties can be easily tied and untied, providing secure closure without the weaponization risk of rigid components, and can be replaced if worn.
2Reliability
If traditional closing structures are used, then secure closure is achieved, but the cost increases making the bag impractical for institutional facilities with limited budgets
Solution Approach 1:
The closing function is merged into the bag's fabric structure itself through integrated tie sections, eliminating the need for separate, expensive fastening components. The closure mechanism is created from the same material as the bag body, reducing part count and manufacturing complexity.
Solution Approach 2:
The invention employs simple fabric ties instead of expensive metal or plastic hardware. These fabric components are inexpensive to manufacture from standard bag materials and can be easily produced in large quantities, making the bag cost-effective for institutional purchasing.
3Reliability
If complex closing mechanisms are used, then secure closure is achieved, but the device complexity and manufacturing complexity increase
Solution Approach 1:
The patent extracts and removes complex closing mechanisms (drawstrings, clasps, connectors) from the bag design, retaining only the essential closure function implemented through simple tied fabric sections. This dramatically reduces the number of components and assembly steps required.
Solution Approach 2:
Instead of adding complex fastening mechanisms to secure the bag, the invention inverts the approach by using simple fabric ties that are integrated into the bag structure itself. The closure is achieved through the basic act of tying, which is simpler than any mechanical fastening system.

AI summary
A two-panel bag constructed from first and second panels that each has the same shape and size. The panels are connected together and a top edge is open for accessing the interior space. The top edge of the panels form handles that can be tied together to close the interior space. The two panels have a laterally inverted shape relative to a centerline. The top edge of each panel further includes two identical sections that each has a vertically-and-rotationally inverted shape. The shape of the panels facilitates manufacturing as the panels can be cut from a flat sheet with limited or no wasted material.
