Lawn Bag Foldable Flaps for Stability and Ease of Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lawn bags are often expensive, cumbersome, and complicated, making it difficult to maintain their shape and prevent movement while inserting debris, leading to frustrating clean-up activities during landscape maintenance.
Innovation Solution
A lawn bag design featuring foldable and bendable side flaps that can be easily extended to maintain an open position, allowing users to straddle the bag for efficient debris collection, and a removable accessory with footholds and clips for improved stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If prior art bags and attachments are used to maintain bag shape and prevent movement, then the bag stability is improved, but the device complexity and cost increase
Solution Approach 1:
The bag is divided into functional segments: a main bag body and separate stabilizing flaps that can be independently deployed. The flaps are attached at specific locations (front, rear, and sides) to provide distributed stability without requiring a complex overall structure. This segmentation allows the bag to achieve stability through simple, localized elements rather than a complicated integrated system.
Solution Approach 2:
The invention uses simple, inexpensive flap elements made from the same or similar material as the bag itself. These flaps are basic geometric shapes with grommets and ties, avoiding expensive materials or complex manufacturing. The design accepts that these are single-use items that will be discarded after one filling operation, eliminating the need for durable, complex attachments.
2Stability of the object's composition
If prior art attachments like hoops and handles are added to prevent bag movement, then the bag stability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The stabilizing flaps are made from the same material and are manufactured as integral parts of the bag itself, rather than being separate attachments. The flaps are formed during the same bag manufacturing process, eliminating the need for separate production of hoops, handles, or other attachments. This merging of components simplifies manufacturing while providing the needed stability function.
Solution Approach 2:
The flaps serve multiple functions: they act as stabilizing elements to prevent bag movement, provide attachment points for ties, and can be positioned to guide debris into the bag. This multi-functionality eliminates the need for separate specialized attachments for each function, simplifying both manufacturing and the overall device structure.
3Shape
If complex prior art attachments are used to keep bag opening open, then the bag shape maintenance is improved, but the ease of operation deteriorates
Solution Approach 1:
The flaps are designed to be dynamic rather than fixed - they can be folded out to the desired position to maintain the bag opening shape, then folded back against the bag body when not needed. This dynamic positioning allows the user to easily adjust the flaps during operation without dealing with complex fixed structures or multiple attachment points.
Solution Approach 2:
The flaps are made from flexible material that can be easily folded and positioned. The flexibility allows the flaps to conform to the bag shape and be easily manipulated by hand during the loading operation. The thin, flexible nature of the flaps makes them simple to deploy and retract without requiring complex mechanical mechanisms.

AI summary
The lawn bag generally comprises a bag bottom, bag sides, and left-side and right-side flaps, each foldingly connected to one of the bag sides. The left-side and right-side flaps are each moveable from stowed positions to extended positions. The flaps in the stowed position may be positioned flat against the respective sides to which they are attached. The left-side flap and the right-side flap, when in the extended position, extends to the left and right of the bag, respectively, and are generally coplanar with a bag front side.
