Solution Overview

Problem

Existing debris blowers are inefficient and labor-intensive due to their vertical orientation, limiting airflow directionality and requiring manual operation, which is impractical for large areas and varied landscapes.

Innovation Solution

A horizontally mounted debris blower design that allows simultaneous airflow discharge in multiple directions, controlled by internal deflectors and actuators, with optional remote operation, powered by the towing vehicle or an alternator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a vertical blower orientation is used, then the blower structure is simple and easy to manufacture, but the airflow directionality is limited and requires manual operation

Engineering Contradiction:

Improveairflow directionalityVSAvoidblower orientation structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent inverts the conventional vertical blower orientation by mounting the blower horizontally. This inversion enables the blower to discharge air in multiple directions (front, back, and sides) simultaneously, eliminating the need for manual deflection and improving operational ease without significantly increasing structural complexity.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transitions from a single-direction vertical airflow to a multi-directional horizontal airflow by changing the spatial dimension of blower mounting. This dimensional change allows air to be discharged in three dimensions (front, back, left, right), providing superior airflow directionality and coverage area.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If a cart-style frame with vertical blower is used, then the blower can be towed or pushed, but it is labor-intensive and awkward to handle in large areas

Engineering Contradiction:

Improvecoverage area efficiencyVSAvoidhandling difficulty

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

By inverting the blower orientation from vertical to horizontal, the patent enables simultaneous multi-directional airflow discharge. This allows the blower to cover larger areas more efficiently without requiring the user to manually redirect airflow or push the cart, thereby improving productivity and ease of operation.

Inventive Principle:

Principle #13The other way round (Inversion)

3Adaptability or versatility

If a vertical blower is used, then the structure is straightforward, but it can only discharge air in one direction without deflection

Engineering Contradiction:

Improveair discharge directionsVSAvoidblower mounting configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies inversion by mounting the blower horizontally instead of vertically. This structural change enables the blower to naturally discharge air in multiple directions (front, back, left, right) without requiring additional deflection mechanisms, thereby increasing adaptability while maintaining reasonable structural simplicity.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent utilizes dimensional change by transitioning from vertical (single-direction) to horizontal (multi-directional) mounting. This spatial reconfiguration allows the blower to discharge air in three dimensions simultaneously, providing versatility for various operational scenarios without significantly complicating the overall device structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Ease of operation

If manual pushing of cart-style blower is required, then the blower can be simple in design, but it increases labor intensity

Engineering Contradiction:

Improveoperational flexibilityVSAvoidlabor intensity

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The patent inverts the conventional design by using a horizontal blower mounting that provides self-directional airflow capability. This eliminates the need for manual pushing or directing of the cart, as the horizontal configuration naturally directs airflow in multiple directions, thereby reducing labor intensity while maintaining operational flexibility.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

The invention is a debris blower horizontally mounted on a cart that can be fabricated to be towed or self-powered by a rider. The blower is mounted on the cart horizontally, with an air discharge chute on either side. The blower can also have a front and/or back discharge chute. The air travels from the blower in a circular pattern around the blower channel and escapes unimpeded through the discharge chutes. The air traveling in a circular pattern will also escape from the front and/or back discharge chute unimpeded. Deflectors control the amount of air that flows through the discharge chutes. The deflectors are operated by actuators that the user controls through controls on the unit or by remote control. The controls can be wireless.
