Self-standing Bag Foldable Flange Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional self-standing bags are unstable when expanded due to tilted side walls and lack effective advertising space, leading to poor commercial presentation and user experience.
Innovation Solution
The design incorporates foldable flanges at the top of two side walls, allowing them to expand into a tubular shape for stability and increasing advertising space, with a nozzle that can be easily integrated and foldable for user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the conventional self-standing bag is expanded by objects, then the bottom area is increased, but the side wall becomes tilted and the bottom wall stretches into an arced shape, leading to instability
Solution Approach 1:
The bag structure is divided into multiple functional components: a bottom wall, side walls with foldable flanges, and a top wall. The foldable flanges are segmented extensions at the top of side walls that can be folded down to create a flat base, distributing the load and providing multiple support points that prevent tilting and maintain stability when the bag is expanded.
Solution Approach 2:
The foldable flanges extend the bag structure vertically by adding a dimensional element at the top of the side walls. When folded down, these flanges create a flat, stable base that expands the effective support area without increasing the bottom wall's arcing, thereby maintaining stability while accommodating expanded contents.
2Ease of manufacture
If the conventional self-standing bag is designed with limited ad space on side walls, then the structure remains simple, but the commercial effect and marketing visibility are reduced
Solution Approach 1:
The foldable flanges add a vertical dimensional element at the top of the side walls, creating additional surface area for advertising. When the bag is in its expanded state, the flanges can be folded down to form a flat extension that provides extra ad space without complicating the basic bag structure or manufacturing process.
Solution Approach 2:
The flanges are designed to be foldable, transitioning between an upright position during storage and a folded-down position during use. This dynamic structure allows the same component to serve dual purposes: maintaining structural integrity during storage and providing extended advertising space during use, without requiring separate designs for each function.
3Device complexity
If the top wall is connected continuously to side walls, then the structure is simple, but the nozzle integration is limited and the flange functionality is reduced
Solution Approach 1:
The top wall connection structure is segmented rather than continuous, with the foldable flanges creating distinct connection points between the top wall and side walls. This segmentation allows for flexible nozzle integration at different positions (central or lateral) on the top wall, as the folded flanges can accommodate various nozzle configurations without compromising structural integrity.

AI summary
A self-standing bag with foldable flanges includes a main body, available with two corresponding side walls and a top connected at the top of two side walls. A nozzle is set centrally or laterally onto the top wall, and covered by a cover in openable state. The foldable flanges are arranged at the top of two side walls of the main bag body, and openings are formed between two corresponding sides of the foldable flanges. The self-standing bag can be positioned more reliably for an improved advertising effect.
