Solution Overview

Problem

Existing methods for cleaning up leaves and debris in outdoor areas, especially in corners near homes and garages, are labor-intensive and ineffective, leading to mold and moss accumulation and attracting rodents.

Innovation Solution

A portable, biodegradable leaf catcher device with a mesh screen supported by tent poles that collects leaves and debris, allowing them to be easily disposed of without manual effort, and prevents mold and moss accumulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional raking and brooming methods are used to clean leaves, then leaves can be removed from accessible areas, but extensive time and manual effort are required, and corners remain difficult to reach

Engineering Contradiction:
Improveleaf cleanup efficiencyVSAvoidtime required for leaf removal
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The device allows leaves to collect themselves in corners through wind accumulation, eliminating the need for active raking or brooming. The corner geometry naturally guides leaves into the collection chamber, making the cleaning process passive and automated.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention transitions from ground-level raking to a three-dimensional collection chamber that extends vertically and diagonally into the corner space, utilizing previously inaccessible volumetric space for leaf collection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If leaves are left in corners for extended periods, then collection frequency can be reduced, but mold and moss accumulate and rodent infestations occur

Engineering Contradiction:
Improvecollection frequencyVSAvoidmold and rodent accumulation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The device proactively captures leaves at the source (corners) before they can decompose and create harmful conditions. By providing immediate collection capacity, it prevents the timeline for mold and rodent development.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The collection chamber is designed as a disposable or easily replaceable component that can be quickly emptied or replaced, enabling frequent collection cycles without investing in complex permanent infrastructure.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Productivity

If a permanent fixed structure is installed to collect leaves in corners, then collection effectiveness is maximized, but portability and ease of installation are reduced

Engineering Contradiction:
Improveleaf collection effectivenessVSAvoidinstallation and portability
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The device transitions from static permanent structures to dynamic portable units that can be assembled, deployed, and disassembled as needed. This allows flexible placement in multiple corners without permanent construction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The collection system is divided into modular components (collection chamber, support structure, discharge mechanism) that can be independently assembled and configured for different corner geometries and sizes.

Inventive Principle:
Principle #1Segmentation

4Duration of action of stationary object

If conventional non-biodegradable materials are used for the device structure, then durability and reusability are improved, but environmental impact increases

Engineering Contradiction:
Improvedevice lifespanVSAvoidenvironmental pollution
Core Design Contradiction:
Duration of action of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The material selection shifts from conventional durable plastics or metals to biodegradable alternatives, changing the degradation parameter from indefinite to controlled natural decomposition after useful life.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The device is designed for controlled end-of-life disposal through biodegradation, returning materials to the environment naturally rather than requiring complex recycling infrastructure or permanent retention.

Inventive Principle:
Principle #34Discarding and recovering

AI summary

The present invention relates to a novel leaf and debris catcher device for catching leaves and other debris blown into and around corners of a home, fence, garage, and more, due to strong winds and other weather and seasonal conditions. The device has a mesh screen around the side surfaces and the bottom surface and has an open top surface from where the leaves and other debris are blown into the device. The device is portable, biodegradable, and can be folded when not in use. The device has a plurality of poles that enable freestanding of the catcher device which can be placed indoors or outdoors. The leaves and debris collected inside the device can be easily collected for disposal via a reusable mesh trash bag.
