Y-Shaped Air Dam for Leaf Blower Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The process of collecting lawn debris using a leaf blower is laborious due to the difficulty in directing air flow into a collection container, often requiring repetitive manual effort to gather and place debris, especially in windy conditions.
Innovation Solution
An air dam and lawn/debris collection container connector system with two panels oriented at an obtuse angle to focus air blown from a leaf blower into a central container, minimizing manual effort and ensuring efficient debris collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a leaf blower is used to blow debris into a collection container, then debris collection speed is improved, but the ability to precisely direct air flow into the container deteriorates due to natural crosswinds and chaotic air flow
Solution Approach 1:
The patent introduces air dams as intermediary structures positioned between the leaf blower and the collection container. These air dams serve as mediators that channel and direct the chaotic air flow generated by the leaf blower, focusing it into a controlled stream that precisely enters the container opening, thereby resolving the contradiction between high-speed debris collection and precise air flow direction control
Solution Approach 2:
The patent modifies the physical parameters of the air flow path by introducing structural elements (air dams) that change the flow characteristics. The air dams alter the velocity distribution, direction, and concentration of the air flow, transforming it from a scattered pattern to a focused stream that reliably enters the container, thus improving direction control while maintaining collection speed
2Manufacturing precision
If manual collection methods are used to gather and place debris into the container, then precision in debris placement is improved, but labor effort and time required increase significantly
Solution Approach 1:
The patent replaces the manual mechanical action of bending, gathering, and placing debris with an automated pneumatic system. The leaf blower generates air flow that carries debris directly into the container, eliminating the need for repetitive manual operations while maintaining precise debris placement through the controlled air stream
Solution Approach 2:
The system enables debris to be collected and placed into the container through its own movement and the air flow generated by the leaf blower. The debris is carried by the air current itself rather than requiring manual handling, making the collection process self-executing and eliminating repetitive manual labor
3Productivity
If air flow is blown into a large pile atop a tarp for collection, then debris gathering is improved, but the subsequent process of siphoning and pickup becomes awkward and laborious
Solution Approach 1:
The patent merges the debris collection function with the container itself by directing air flow directly into the container opening. This eliminates the need for intermediate collection surfaces like tarps and consolidates the entire collection process into a single straightforward operation, removing the awkward siphoning step entirely

AI summary
A Y-shaped air dam with a central frame configured to facilitate the focusing of air from a lawn and leaf blower for the collection of leaves and similar lawn debris into collection containers, exhibiting two panels connected to a central frame. The central frame is equipped with retaining clips configured to facilitate attachment of a collection container such as a paper bag to the central frame securely without tools. The two panels pivot about hinges and may be removed from the central frame for storage or folded up when not in use. Stakes may be used to anchor the panels to the ground during use. A companion device may be included which is configured to perforate collection containers such as bags to provide for the passage of air through the containers during use.
