Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging equipment for automatic robot lawn mowers often causes damage to lawns and hinders the operation efficiency due to their installation requirements and size, and they are not effectively integrated with the boundary wire system.
Innovation Solution
A charging equipment system for moving robots that includes a bottom unit with holes to minimize lawn damage, a supporting unit with adjustable rods and IR sensors for precise alignment, and a terminal unit that can change its coupling angle to maintain contact with the robot, all while being installed outside the boundary wire, reducing the shared region with the operation area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If charging equipment is installed within the operation region, then power supply to the robot is ensured, but lawn damage occurs and operation efficiency is hindered
Solution Approach 1:
The charging equipment is extracted from the operation region and installed outside the boundary wire, separating the charging function from the mowing area to eliminate lawn damage while ensuring power supply reliability
Solution Approach 2:
The boundary wire serves as an intermediary element that defines the operation region boundary and provides a mounting reference for the charging equipment, enabling installation outside the operation region while maintaining functional integration
2Reliability
If charging equipment is installed inside the boundary wire, then power supply is achieved, but the shared region between installation region and operation region increases
Solution Approach 1:
The charging equipment is relocated from inside the boundary wire to outside the boundary wire, extracting it from the operation region to minimize the shared region area while maintaining power supply functionality
Solution Approach 2:
The installation location is shifted from a two-dimensional plane within the boundary to a position outside the boundary, utilizing the spatial dimension outside the operation region to reduce overlap
3Reliability
If traditional charging equipment is used, then power supply function is provided, but device size and installation region are large
Solution Approach 1:
The charging equipment is segmented into three functional units (bottom unit for stability, supporting unit for adjustment, terminal unit for contact) that can be independently optimized and assembled, reducing overall device volume while maintaining power supply function
Solution Approach 2:
The supporting unit incorporates adjustable rods that can extend or retract, allowing the charging equipment to adapt its size and position dynamically, minimizing the installation footprint while ensuring reliable power supply
