Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic lawn mower systems lack flexibility in boundary cutting, as they typically perform uniform cutting along the entire boundary, failing to accommodate user-defined preferences for specific cutting areas.
Innovation Solution
A method for a robotic lawn mower system that allows users to control boundary cutting through a user terminal, where boundary data is acquired and presented to the user, enabling them to define specific boundary parts for cutting, and the mower is programmed to perform boundary cutting only along those defined parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform boundary cutting is performed along the entire boundary, then the boundary cutting function is simple to implement, but the system lacks flexibility to accommodate user-defined preferences for specific cutting areas
Solution Approach 1:
The boundary is divided into multiple selectable segments or portions, allowing users to choose specific sections for boundary cutting. The system processes boundary cutting requests by identifying and executing cuts only on the selected boundary portions rather than the entire boundary, thereby providing flexibility while maintaining manageable system complexity through modular processing.
Solution Approach 2:
The boundary cutting configuration is made dynamic and adjustable through a user interface, allowing users to modify which boundary portions undergo cutting. The system adapts to user preferences by enabling real-time selection and modification of boundary cutting sections, transforming a static uniform cutting approach into a flexible, user-defined process.
2Productivity
If boundary cutting is performed along the entire boundary, then the cutting coverage is comprehensive, but the cutting time and energy consumption increase
Solution Approach 1:
The system extracts or selects only the necessary portions of the boundary that require cutting, separating them from the portions that do not. By identifying and isolating specific boundary sections for cutting based on user selection, the system performs cuts only where needed, reducing overall cutting time and energy consumption while maintaining comprehensive coverage of areas that actually require boundary cutting.
Solution Approach 2:
Instead of performing cutting along the entire boundary (excessive action), the system applies cutting only to the specifically selected portions (partial action). This partial action approach optimizes resource utilization by concentrating cutting efforts only where necessary, thereby improving productivity while minimizing time loss.
3Ease of operation
If users can define specific boundary parts for cutting, then the system becomes more flexible and user-friendly, but the control system complexity increases
Solution Approach 1:
A user interface acts as an intermediary between the user and the control system, providing a simplified means for users to select and define boundary portions for cutting. The interface translates user selections into control signals that the system can process, thereby enhancing ease of operation while shielding users from the underlying control system complexity through an intuitive interaction layer.
Solution Approach 2:
The system creates a digital representation or model of the boundary with selectable portions, allowing users to interact with this virtual copy rather than directly controlling the physical cutting process. Users can visualize and select boundary sections on a display interface, and the system maps these selections to actual cutting operations, simplifying user interaction while managing control complexity through the digital model.

This solution enables precise and flexible boundary cutting, allowing users to customize cutting areas within the operation boundary, improving the efficiency and effectiveness of robotic lawn mower operations.
Implementation Method 1
An electric control signal may be transmitted through the boundary wire thereby generating an (electro-) magnetic field emanating from the boundary wire. The robotic working tool is typically arranged with one or more sensors adapted to sense the control signal.

AI summary
The present disclosure relates to a robotic lawn mower that is adapted to operate within an operation area defined by a boundary and comprises a mower control unit adapted to control the operation of the robotic lawn mower. The mower control unit is adapted to receive data defining at least one boundary part, comprised in the boundary, where the mower control unit is adapted to control the robotic lawn mower to perform boundary cutting along said boundary part, and to perform normal cutting along the rest of the boundary. The boundary cutting is a procedure adapted to enable cutting over the boundary in a pre-defined manner.
