Landscaping Cart Spring-Loaded Barrow for Direct Debris Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current landscaping tools are inefficient and require excessive effort to accumulate and transport yard debris, as they necessitate raking debris into piles before collection and transportation, lacking mechanical advantage.
Innovation Solution
A landscaping cart with a barrow frame that can be raised and lowered using a spring mechanism, allowing debris to be collected directly into a wheeled cart, reducing physical effort and enabling efficient transportation without the need for initial pile formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional landscaping tools are used to collect yard debris, then debris can be transported, but excessive physical effort is required and the process is time-consuming
Solution Approach 1:
The patent combines the barrow (collection container) and cart (transport vehicle) into a single integrated unit. The barrow frame attaches to the cart frame, merging the collection and transport functions so that debris can be loaded directly onto the moving cart without requiring separate operations for pile formation and transport.
Solution Approach 2:
The barrow frame is designed to be movable between a raised position (for loading debris) and a lowered nested position (for transport). This dynamic positioning allows the barrow to adapt to different operational phases, eliminating the need for manual pile formation while maintaining ease of operation.
2Productivity
If debris is raked into piles before collection, then debris can be gathered, but additional physical effort and time are required
Solution Approach 1:
The cart is positioned with its barrow frame raised and ready before the raking action begins. The mouth end of the barrow frame is positioned to receive debris directly as it is raked, eliminating the need for preliminary pile formation and allowing collection to start immediately.
Solution Approach 2:
The barrow frame acts as an intermediary between the raking action and the final collection container. It receives debris directly from the rake and transfers it to the cart body, serving as a bridge that eliminates the need for intermediate pile formation.
3Ease of operation
If a barrow frame is raised above the cart frame for collection, then debris can be loaded directly, but the structure becomes more complex
Solution Approach 1:
The barrow frame is designed to nest within the cart frame when not in use, creating a compact storage configuration. When debris collection is needed, the barrow frame can be raised to the operational position. This nesting arrangement reduces structural complexity by eliminating the need for separate, permanent raised collection structures.
Solution Approach 2:
The barrow frame's ability to move between raised and lowered positions provides the necessary elevation for direct debris loading without requiring complex permanent structural additions. The dynamic nature of the frame allows it to function as a temporary elevated platform only when needed.

AI summary
A landscaping cart is provided. The landscaping cart has a barrow portion operatively associated with a cart frame having wheels. The cart frame provides an open configuration dimensioned and adapted to accommodate the barrow portion in a nested condition so that the barrow portion can slide and rotate therein. The barrow portion provides an external spring mechanism that enables the barrow portion to move from a supported position on top of the cart frame to the nested position for the process of urging lawn debris into the barrow portion. The supported position facilitates upright transportation of the lawn debris retained in the barrow portion. The cart frame may provide a support bar for supporting the barrow portion in the nested condition. A bucket portion for compacting the lawn debris connects to a distal end of the barrow portion.
