Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lawn care methods, including manual removal and chemical substances, are inefficient and environmentally harmful, and existing robotic systems are costly, heavy, and unsuitable for garden use.
Innovation Solution
A robot lawn care apparatus equipped with a digital camera, control device, and motorized tool that performs object recognition to automatically remove weeds and collect debris like cones, needles, and leaves without chemicals or noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual procedures are used to remove weeds and collect debris, then the workload is high, but the solution is simple and requires no special equipment
Solution Approach 1:
The system performs lawn care tasks autonomously without human intervention. The control device automatically processes camera images, recognizes objects using algorithms, and controls the tool to perform work steps, enabling the system to serve itself and eliminate manual labor.
Solution Approach 2:
Manual mechanical operations are replaced by an automated system combining digital camera, control device with object recognition algorithm, and motorized tool. The system substitutes human physical labor with an integrated electromechanical automation system.
2Productivity
If chemical substances are used to destroy weeds, then the weed removal is effective, but the soil and environment are contaminated
Solution Approach 1:
Chemical weed destruction is replaced by mechanical removal using a motorized tool. The system physically removes weeds through mechanical action rather than chemical treatment, eliminating soil and environmental contamination while maintaining effective weed removal.
3Productivity
If leaf blowers are used to remove leaves, then the leaf removal is efficient, but noise and fine dust pollution are generated
Solution Approach 1:
Air-based leaf blowing is replaced by mechanical collection using a motorized tool. The system physically collects leaves through contact-based mechanical action rather than air flow, eliminating noise and fine dust pollution while maintaining efficient leaf removal.
4Extent of automation
If known robots for weeding agricultural land are used, then the automation is achieved, but the cost, weight, and size are too high for garden use
Solution Approach 1:
The system is divided into separate functional modules: a digital camera for detection, a control device with object recognition algorithm for decision-making, and a motorized tool for execution. This segmentation allows the system to be compact and adaptable for garden use while maintaining full automation.
Solution Approach 2:
The motorized tool can perform multiple functions including weed removal and collection of various debris such as cones, needles, and leaves. This multi-functionality reduces the need for multiple specialized devices, decreasing overall system weight and size while maintaining high automation level.

AI summary
A lawn care apparatus which can be mounted on a mobile unit and includes a digital camera, which can be oriented towards the lawn, and a control device and at least one tool which can be controlled by the control device and can be lowered to the lawn by a motor. The images from the digital camera are supplied to an algorithm implemented in the control device to perform object recognition so that upon recognition of an object, the control device lowers the tool in order for a work step to be performed on the object.
