Lawnmower Allocation Server for Mixed-Area Mowing Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lawn-mowing systems face challenges in determining the optimal combination of small and large lawnmowers for efficient and safe lawn-mowing work, as users struggle to decide the number of each type needed for different areas and conditions.
Innovation Solution
A server device that sets distinct areas for small and large lawnmowers, calculates the time required for each, and notifies a terminal device of the necessary number of machines and times to complete the work efficiently and safely, considering factors like size, speed, and complexity of the area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lawn-mowing work is conducted by multiple lawnmowers with different sizes and speeds, then work efficiency is improved, but it becomes difficult for users to decide the optimal number and combination of lawnmowers
Solution Approach 1:
The server acts as an intermediary between the user and the complex decision-making process. It receives work area information from the user, automatically calculates the optimal number and combination of lawnmowers based on predefined criteria, and provides this information to the user through the terminal device, thereby eliminating the difficulty of manual decision-making
Solution Approach 2:
The system enables self-service by automatically performing the calculation and optimization tasks that would otherwise require user expertise. The server autonomously analyzes the work area, determines the appropriate lawnmower configuration, and presents the results to the user without requiring manual intervention or specialized knowledge
2Productivity
If lawnmowers with larger size and higher speed are used, then work efficiency is improved, but they are unsuitable for detailed work in complex areas
Solution Approach 1:
The work area is segmented into multiple regions with different characteristics (e.g., open areas, areas with obstacles, detailed work zones). Each region is assigned appropriate lawnmower types based on its specific requirements, allowing the system to simultaneously achieve high productivity in open areas and adaptability in complex zones
Solution Approach 2:
Different lawnmower configurations are assigned to different regions of the work area based on local characteristics. Large, high-speed lawnmowers are deployed in open areas for efficient bulk work, while smaller, more maneuverable lawnmowers are assigned to areas with obstacles or requiring detailed work, ensuring optimal performance in each local zone

AI summary
A server device includes an area setting unit that sets a first area in which a first lawnmower executes first lawn-mowing work in a work area and a second area in which a second lawnmower executes second lawn-mowing work in the work area, a time calculation unit that obtains a first time necessary for the first lawnmower to execute the first lawn-mowing work in the first area and a second time necessary for the second lawnmower to execute the second lawn-mowing work in the second area, a machine number calculation unit that obtains the number of first lawnmowers and the number of second lawnmowers based on the first time and the second time, and a notification unit that notifies the number of first lawnmowers and the number of second lawnmowers to a smartphone. Consequently, a user can check the number of first lawnmowers and the number of second lawnmowers.
