Detachable Stationary Base Assembly for Robotic Mower Docking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous working systems, such as robotic lawn mowers, face challenges with stationary devices that are cumbersome to install and disassemble, exposed to harsh weather, and prone to theft, with inadequate mechanical and electrical designs that hinder size reduction and maintenance convenience.
Innovation Solution
A detachable connection mechanism for stationary devices using a first and second base with rotating shafts, buckles, and elastic elements allows for easy assembly and disassembly, enhancing stability and weather resistance while reducing packaging size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stationary device is nailed to the lawn using ground nails, then the device is securely fixed on the working surface, but the installation and disassembly become cumbersome and the device is exposed to harsh weather all year round
Solution Approach 1:
The stationary device is divided into two separable parts: a first base that remains fixed on the lawn and a second base that can be detached. The first base includes ground nails for secure installation, while the second base contains the control assembly and can be easily removed for storage or maintenance, thus resolving the contradiction between stable fixation and ease of operation.
2Stability of the object's composition
If the stationary device is nailed to the lawn, then the device remains fixed in position, but it increases the risk of being stolen and requires improved weather resistance
Solution Approach 1:
By separating the stationary device into a fixed first base and a removable second base, the valuable components (control assembly, electrical components) are contained in the second base that can be taken indoors for storage during off-seasons, thereby reducing theft risk. The first base remains fixed to maintain position stability, while the removable second base can be protected from harsh weather when not in use.
3Stability of the object's composition
If the mechanical structure is designed for secure fixation, then the device is stable, but the packaging size and device complexity increase
Solution Approach 1:
The segmentation of the stationary device into two bases with a simple connecting portion reduces overall structural complexity. The first base contains only the essential fixing structures (ground nails, first base connecting portion), while the second base houses the control assembly. This modular design simplifies each component's structure while maintaining overall stability.
Solution Approach 2:
The control assembly and electrical components are extracted into a separate second base that can be independently handled. This extraction allows the first base to have a simpler, more compact structure focused only on fixation and connection functions, reducing packaging size and structural complexity.
