Leaf Vacuum Cart With Hopper for One-Step Yard Bagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for leaf and yard debris collection do not provide a seamless, one-step process for collecting and disposing of leaves and debris, lacking mobility and efficient bag attachment mechanisms.
Innovation Solution
A mobile cart system with a two-tiered design, accommodating leaf blower vacuums, featuring a hopper with a shock-corded standard 12″×16″×35″ paper yard waste bag, a fabric air regulator bag, and flexible hoses for connecting the blower vacuum to the hopper, enabling one-step collection and disposal with mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a standard leaf blower vacuum is used for debris collection, then the operation requires multiple steps (collection and disposal separately), but the invention integrates bag attachment and disposal into one step
Solution Approach 1:
The patent combines the collection function (hopper and vacuum) with the disposal function (attached bag) into a single integrated system. The bag is directly attached to the hopper, allowing debris to be collected and disposed of in one continuous operation without requiring separate collection and disposal steps.
Solution Approach 2:
The cart system serves multiple functions: it provides mobility for the leaf blower vacuum, holds the hopper for collection, and secures the disposal bag. This multi-functional design consolidates what would traditionally require separate devices into one universal platform.
2Ease of operation
If a mobile cart system is introduced to enable mobility, then the operation becomes mobile and flexible, but the system complexity increases
Solution Approach 1:
The cart is designed as a segmented modular system with distinct components: the cart frame, the hopper assembly, the bag attachment mechanism, and the vacuum support. This segmentation allows each component to be independently designed and assembled, reducing overall system complexity while maintaining mobility.
3Reliability
If a shock cord mechanism is used to secure the bag to the hopper, then the bag attachment is secure and reliable, but the attachment mechanism becomes more complex
Solution Approach 1:
The shock cord mechanism is a self-tensioning system that automatically secures the bag to the hopper. The elastic nature of the shock cord provides automatic tension and secure attachment without requiring additional fasteners, clips, or complex locking mechanisms, achieving reliable attachment through a simple elastic element.

AI summary
A leaf blower vacuum cart for mounting, transporting and utilizing an electric leaf vacuum blower and a standard 12″×16″×35″ paper yard waste bag or similar. The invention is a two tiered cart with casters, a bottom shelf and a top shelf. The top shelf has an opening to accommodate a hopper which goes into a standard 12″×16″×35″ paper yard waste bag or similar. The cart can be used with leaf blower vacuums of various makes. A hose is attached to the leaf blower vacuum allowing for extended reach of leaves. A second hose is connected to the exhaust of the leaf blower vacuum and to the hopper. The invention maximizes filling of standard 12″×16″×35″ paper yard waste bags or similar. Full bags are moved on the cart to the desired location.
