Solution Overview
Problem
The existing intelligent lawn mowers face issues with the upper housing aging and fracturing due to sun exposure and impact, and the conductive wires complicating the replacement of the upper housing.
Innovation Solution
The autonomous operation device features a chassis with snap-fitted cover bodies, where electronic devices are arranged in a chassis sealing cavity, and electrical connections are maintained through connectors that separate with the cover bodies, allowing easy replacement of components without affecting disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the upper housing is made of plastic material and connected through conductive wire to components on the lower housing, then the housing provides structural enclosure and electrical connection, but the housing becomes prone to aging and fracture due to sun exposure and impact, and replacement is complicated
Solution Approach 1:
The housing is divided into an upper housing and a lower housing that can be separated. The upper housing can be replaced independently without removing the lower housing, allowing selective replacement of the damaged portion while retaining the intact lower housing and its components.
Solution Approach 2:
The conductive wire connecting the upper and lower housings is extracted and replaced with a magnetic connection system. The magnetic connection allows electrical connection without physical wire attachment, enabling the upper housing to be detached and replaced without dealing with wire disconnection.
2Ease of operation
If conductive wires are used to connect electronic components between upper and lower housings, then electrical conduction is achieved, but the disassembly and replacement of the upper housing becomes complex and time-consuming
Solution Approach 1:
The mechanical wire connection system is replaced with a magnetic connection system. The magnetic connection provides electrical conduction through magnetic attraction and contact, eliminating the need for physical wire attachment and detachment, thereby simplifying the disassembly and assembly process.
3Ease of repair
If the upper housing is designed to be replaceable, then maintenance and repair become easier, but the electrical connection between housings becomes more complex
Solution Approach 1:
The conductive wire is extracted from the connection system and replaced with a magnetic connection mechanism. This allows the upper housing to be replaced without dealing with wire disconnection, as the magnetic connection automatically establishes electrical contact when the housings are brought together.
Solution Approach 2:
The magnetic field acts as an intermediary between the upper and lower housings, providing both mechanical attraction for connection and electrical conduction. This intermediary mechanism simplifies the connection process by combining mechanical and electrical functions in a single interaction.
