Foldable Frame with Integrated Clamps for Leaf Blower Bagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for collecting garden and lawn debris, such as leaves and grass trimmings, are not self-contained, require assembly, and lack a secure clamping system to hold bags in place, especially when using a powered leaf blower.
Innovation Solution
A foldable, self-contained frame with integrated bag clamps that securely attach and detach disposable or reusable bags, allowing for easy collection of debris blown by a leaf blower or raked into the bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a frame-bag combination device is provided for raking leaves, then the bag can be supported with the mouth open, but the device is not stable for blowing and lacks a clamping system to secure the bag
Solution Approach 1:
The device is divided into separate functional components: a stable frame structure for support, integrated clamps for securing the bag, and a handle for operation. This segmentation allows each component to be optimized independently - the frame provides stability for blowing while the clamps secure the bag, resolving the contradiction between bag support and blowing stability.
Solution Approach 2:
The clamps are integrated directly into the frame structure, merging the bag-securing function with the support structure. This integration ensures that the bag is firmly clamped to the frame during blowing operations, providing both stability and reliability simultaneously.
2Ease of operation
If a frame is provided for supporting the bag, then the bag mouth can be kept open, but the frame requires assembly by the user and is not self-contained
Solution Approach 1:
The frame is pre-assembled and ready for use, with clamps already integrated into the structure. This preliminary preparation eliminates the need for user assembly while maintaining the bag-support function, reducing device complexity and making the device self-contained.
3Reliability
If a clamping system is added to secure the bag, then the bag can be firmly held, but the device complexity increases
Solution Approach 1:
The clamps are merged with the frame structure itself, forming an integrated component rather than a separate attachment. This merging provides firm bag security while minimizing additional complexity, as the clamps become part of the frame's inherent design rather than an add-on system.

AI summary
Large, pliable/flexible bags are widely used for collecting and discarding garden and lawn debris. Unfortunately, these bags alone make it very difficult for a single worker to both hold open the bag and deposit debris into the bag at the same time. Attempts have been made to provide frames for supporting an open bag to help a single user rake leaves and debris into a bag by him/herself; none have ever been created to blow leaves and other debris directly into a bag with a powered leaf blower—the device in this patent application is designed to do just that. Very significantly, the present invention is a foldable/collapsible self-contained fully assembled frame (hereinafter “the frame”) for the attachment of a perforated bag thereby requiring no additional add-on or separate frame parts to both fully function and to fold up for convenient storage, packaging, and transportability.
