Bag Support Frame for One-Handed Lawn Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag holders fail to effectively hold open a bag while collecting debris, such as leaves and grass clippings, leading to inefficiencies in the collection process.
Innovation Solution
A bag holder with a bag support frame and handle that allows the open end of the bag to be folded over, creating a secure and taut connection without the need for additional securing mechanisms, and a footing that establishes a wide flat edge for ground contact, facilitating one-handed manipulation and debris collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bag mouth is held open manually during debris collection, then the bag can be filled efficiently, but the user requires two hands (one for holding the bag open, one for raking/sweeping)
Solution Approach 1:
The bag holder device enables the bag to hold itself open through its own structural support frame, eliminating the need for manual intervention to keep the bag mouth open. The frame's geometry and the bag's elastic material work together to automatically maintain the open state during debris collection.
2Stability of the object's composition
If the bag is secured tightly to the bag holder, then the bag remains stable during use, but the bag mouth becomes difficult to keep open for debris insertion
Solution Approach 1:
The bag holder applies different functional qualities to different parts of the bag: the lower portion is secured tightly to the frame for stability, while the upper mouth portion remains loosely held open by the frame's geometry, allowing easy debris insertion. This localized differentiation of constraint levels resolves the contradiction between stability and accessibility.
3Reliability
If a complex securing mechanism is added to the bag holder, then the bag can be more securely attached, but the device complexity increases
Solution Approach 1:
The bag's own elastic material serves as the securing mechanism. When the bag is stretched over the frame, its inherent elasticity provides the necessary holding force to keep the bag securely attached without requiring additional clips, straps, or complex fastening systems.
Solution Approach 2:
The invention utilizes the disposable nature of the bag itself as a securing mechanism. The bag's material properties and single-use design are leveraged to provide secure attachment, eliminating the need for durable, complex, and expensive securing hardware.
4Productivity
If the bag mouth is held open with one hand during debris collection, then debris can be raked in efficiently, but the user cannot simultaneously secure or adjust the bag
Solution Approach 1:
The bag holder device autonomously maintains the bag mouth in an open state through its structural frame design, eliminating the need for continuous manual intervention. This allows the bag to self-adjust and self-maintain its operational state throughout the debris collection process.

AI summary
A bag holder is configured for holding a bag to be filled with lawn debris. The bag holder comprises a bag support frame and a handle attached to the bag support frame. The bag support frame is configured to mount and support the bag. The bag support frame forms a bag opening sized and shaped to receive an open end portion of a bag. The bag holder may be configured in a closed configuration wherein the bag holder is configured to be inserted into a mouth of the bag, and an open configuration wherein the bag holder is configured to permit an open end portion of the bag to be folded over the bag support frame, handle, and back on itself to mount or couple the bag to the bag holder. The handle is sized and shaped so a user may grasp the handle and a portion of the bag.
