Self-Moving Mower With Auxiliary Trimming Around Obstacles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-moving devices, such as robotic mowers, face challenges in safely and efficiently cutting grass around obstacles and boundaries, often leaving uncut areas due to the distance between the cutting blade and the device's perimeter.
Innovation Solution
A self-moving device equipped with an auxiliary working module, a control module, and a wireless communication module, allowing for an auxiliary working mode where the device can perform tasks like trimming and pruning under user control, ensuring safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the protective cover is disposed on the periphery of the cutting system to prevent injury, then user safety is improved, but the distance between the cutting blade and the device perimeter increases, creating uncuttable areas
Solution Approach 1:
The cutting system is divided into two independent parts: a main cutting blade for bulk cutting and an auxiliary cutting module for edge trimming. This segmentation allows each component to perform its specialized function without compromising safety or coverage.
Solution Approach 2:
The auxiliary cutting module acts as an intermediary between the main cutting blade and the boundary obstacles. It extends the cutting capability to areas that the main blade cannot reach due to safety distance requirements, thereby eliminating uncuttable areas while maintaining the protective cover in place.
2Object-affected harmful factors
If the distance between the cutting blade and device perimeter is increased to prevent user contact, then user safety is improved, but uncuttable areas are created around obstacles and boundaries
Solution Approach 1:
The auxiliary cutting module extends the cutting capability in a radial direction outward from the device perimeter, effectively adding another dimension to the cutting reach. This allows the system to cover areas beyond the safety distance of the main blade without compromising user safety.
Solution Approach 2:
The auxiliary cutting module is a simplified version of the main cutting system, designed specifically for edge trimming tasks. It copies the essential cutting function while being optimized for working in confined spaces near boundaries and obstacles.
3Extent of automation
If the device operates autonomously without manual intervention, then automation level is improved, but the ability to perform precise auxiliary tasks like trimming and pruning is reduced
Solution Approach 1:
The system dynamically switches between autonomous and manual control modes based on the task requirements. The auxiliary cutting module can be activated in manual mode for precise trimming and pruning tasks, while the main system operates autonomously for general cutting tasks, providing optimal adaptability.
Solution Approach 2:
The self-moving device is designed with multi-functionality, incorporating both autonomous cutting capability and manual auxiliary cutting capability. This universal design allows the device to handle various cutting tasks independently or with user assistance, enhancing both automation and adaptability.
