Hoop-Config Leaf Collection Apparatus for Ergonomic Debris Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current debris collection methods are inefficient and painful, often requiring repetitive motions that can lead to injuries such as prepatellar bursitis, arthritis, and joint disorders, as they involve bending and kneeling, and existing solutions are either cumbersome, require multiple parts, or fail to hold bags effectively.
Innovation Solution
A lightweight, flat-pack apparatus with a scoop and hinged extensions that create a hoop configuration to hold a trash bag open, allowing debris to be deposited directly into the bag without bending, featuring a beveled leading edge and retention mechanisms for secure bag attachment, enabling efficient and ergonomic debris collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional debris collection methods are used, then debris can be collected, but repetitive bending and kneeling are required which can lead to injuries
Solution Approach 1:
The apparatus divides the debris collection process into two independent functions: aggregation (scoop) and containment (bag holder). This segmentation allows each component to be optimized for its specific function, enabling debris to be aggregated directly into the bag without intermediate transferring, thereby eliminating repetitive bending and kneeling motions
Solution Approach 2:
The apparatus introduces an intermediate structure (the bag-holding apparatus with hoop configuration) that mediates between the aggregation device and the receptacle. This intermediary structure supports the bag open and positioned optimally, allowing direct deposition of debris without requiring the user to bend or kneel to transfer debris manually
2Ease of operation
If existing bag holding apparatus are used, then bags can be held open, but they require many parts which are cumbersome and bulky
Solution Approach 1:
The apparatus merges multiple functions into a single integrated structure: the scoop for aggregation, the extensions that form the hoop configuration for bag support, and the retention mechanism for securing the bag. This consolidation eliminates the need for separate bag holders, clips, and support structures required by prior art
Solution Approach 2:
The flexible extension elements serve multiple functions: they provide structural support for the bag, form the hoop configuration to hold the bag open, and can be collapsed flat for compact storage. This multi-functionality reduces the overall number of parts needed compared to specialized single-function components in existing apparatus
3Ease of operation
If existing bag holding apparatus are used, then bags can be held, but they require large storage space when not in use
Solution Approach 1:
The apparatus employs flexible extensions that can dynamically change configuration: they extend outward to form the functional hoop configuration during use, then collapse inward to a flat profile for compact storage. This dynamic transformation allows the same structure to provide full bag support functionality while occupying minimal storage space
Solution Approach 2:
The extensions nest together in a compact configuration when not in use, with the scoop and extensions storing in a flat-pack arrangement. This nesting principle allows the entire apparatus to be stored in a small volume while maintaining full functionality when deployed

AI summary
An apparatus for the collection of debris such as leaves and other yard debris having a flat-pack configuration and a hoop-like configuration. In a hoop-like configuration, the apparatus allows the fixation of a bag such that the bag is held open and allows the user to dispose debris through the apparatus and into the bag.
