Solution Overview

Problem

Current gardening tools require multiple devices for mowing and trimming, which are time-consuming, tedious, especially for the elderly, and pose safety risks due to power supply limitations and equipment handling challenges.

Innovation Solution

A single gardening apparatus combining a mower and trimmer with a hover mechanism, powered by a single source, featuring adjustable blades and strimmers for efficient cutting and collection, with safety features like a spring-loaded lever and removable components for easy maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple tools (mower, trimmer, rack) are used for lawn maintenance, then cutting functionality is comprehensive, but the process becomes time-consuming and tedious

Engineering Contradiction:
Improvecutting functionalityVSAvoidprocess time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent combines a mower, trimmer, and clipping collection rack into a single integrated apparatus. The mower blades and trimmer blades are mounted on the same housing, allowing both cutting functions to be performed simultaneously or sequentially without switching tools. The rack is integrated into the housing to collect clippings from both cutting operations, eliminating the need for separate collection equipment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single apparatus performs multiple functions: the mower blades cut large areas, the trimmer blades cut edges and small areas, and the rack collects clippings from both operations. This multi-functional design allows one device to replace traditionally separate tools, reducing the number of equipment pieces the user must transport and operate.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If multiple power-powered devices are used, then cutting capability is enhanced, but safety risks increase due to power cable hazards

Engineering Contradiction:
Improvecutting capabilityVSAvoidpower cable risk
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent integrates both the mower and trimmer into a single apparatus powered by one power source. This eliminates the need for multiple power cables that could become entangled or damaged. The unified power connection reduces the risk of exposed wires and cable-related hazards while maintaining the cutting capability of both blade systems.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If traditional wheeled mowers are used, then stability is provided, but the wheels damage the mowed surfaces by pulling up mud and dirt

Engineering Contradiction:
Improvemower stabilityVSAvoidsurface damage
Core Design Contradiction:
Stability of the object's compositionVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the traditional wheeled support system with a hover mechanism. The apparatus is supported by a cushion of air generated by the rotating mower blades, which lifts the housing off the ground. This eliminates mechanical contact between wheels and the mowed surface, preventing wheel-induced damage to grass, mud, and dirt while maintaining stability through aerodynamic lift.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

4Adaptability or versatility

If the apparatus is designed with multiple components, then functionality is comprehensive, but device complexity increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidapparatus structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent integrates the trimmer blades and rack within the housing structure of the mower. The trimmer blades are mounted on the housing in a manner that nests them within the overall apparatus footprint. The rack is also integrated into the housing, allowing clippings from both mower and trimmer to be collected in a unified system. This nesting approach reduces the overall complexity compared to having separate standalone devices.

Inventive Principle:
Principle #7Nested doll (Nesting)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The apparatus simplifies lawn maintenance by eliminating the need for multiple tools, enhances safety through reduced power cord risks, and facilitates easy maneuverability and clipping collection, making the process more efficient and accessible.

Implementation Method 1

the movements of the mower blades form an air cushion/bed under the housing. This air bed can thereby raise the apparatus a small distance, such as 5 to 10 millimetres. Once risen, the gardening apparatus can glide over the surface of the lawn, riding the air bed under the housing

Methodology Applied
Scientific EffectAir cushion: Air Lubrication
