Innovation Solution
A lawn mower equipped with an image input unit, position detection unit, and control unit that processes lawn grass to form images by analyzing the input image and determining appropriate cutting or bending patterns based on position, allowing for automatic image formation without manual path determination and enabling operation at any time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual labor is used to form images on lawns, then the image can be created with simple equipment, but the time required is excessive and work is limited to daytime
Solution Approach 1:
The patent replaces manual mechanical cutting with an automated lawn mower system equipped with image input unit, position detection unit, and control unit. The system automatically determines cutting patterns based on detected images and controls the mowing unit to form images on the lawn, substituting human labor with an automated mechanical system that operates faster and more efficiently.
Solution Approach 2:
The lawn mower system performs self-guided operation by detecting images autonomously, determining optimal cutting paths independently, and executing the mowing pattern without continuous human intervention. The control unit processes detected image data and automatically controls the mowing unit, enabling the system to service itself through automated decision-making.
2Device complexity
If manual labor is used to form images on lawns, then equipment complexity is low, but the time required to complete image formation is excessive
Solution Approach 1:
The patent divides the image formation process into distinct functional segments: image input unit for capturing images, position detection unit for locating the mower and detecting image features, control unit for processing data and determining cutting patterns, and mowing unit for executing the cutting. This segmentation allows each component to specialize in a specific task, improving overall efficiency while managing complexity through modular design.
Solution Approach 2:
The system performs preliminary actions by detecting and analyzing images before the actual mowing process begins. The image input unit captures images and the control unit determines cutting patterns in advance, allowing the mowing unit to execute pre-planned paths efficiently. This preliminary planning reduces on-site decision time and accelerates the overall image formation process.
3Ease of operation
If manual path determination is required, then the system can operate with simple control, but the user must have expertise and cannot work at any time
Solution Approach 1:
The patent replaces manual path determination with automated image detection and processing. The position detection unit detects images and the control unit automatically determines optimal cutting paths based on detected features, substituting human expertise with automated computer vision and control algorithms. This enables operation at any time without requiring skilled operators to interpret images manually.
Solution Approach 2:
The system implements feedback by continuously detecting images during operation, comparing detected features with desired outcomes, and adjusting the mowing path in real-time. The position detection unit provides ongoing feedback about image location and characteristics, allowing the control unit to dynamically modify the cutting pattern to achieve the desired image formation while maintaining operational simplicity.
