Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate gardening machines are used to handle different gardening tasks, then each machine can perform its specific function well, but the overall device complexity and the number of tools required increases significantly
Solution Approach 1:
The patent implements a universal main machine body that can perform multiple gardening functions by accepting different interchangeable function heads. The main machine includes a power system, control system, and connection interface that work with various specialized heads (chain saw head, grass trimmer head, bush saw head, leaf blower head) to provide comprehensive gardening capabilities in a single tool platform.
Solution Approach 2:
The gardening tool is divided into modular components: a main machine body and separate function heads. Each function head is designed as an independent module with specific gardening functions, allowing users to attach only the needed head for each task. This segmentation reduces the need to own multiple complete machines while maintaining functional versatility.
2Power
If traditional electric gardening tools are used, then they can provide sufficient power for gardening tasks, but they require external power supplies or long power cords that limit mobility and outdoor usability
Solution Approach 1:
The power supply system is extracted from the traditional external power source configuration and integrated into a portable battery pack that is directly mounted on the main machine body. This extraction eliminates the need for external power cords or generators, allowing the tool to operate independently in outdoor locations without access to electrical infrastructure.
Solution Approach 2:
The power supply configuration transitions from a static external power source to a dynamic portable battery system. The battery pack can be repositioned, recharged, or replaced as needed, providing flexible power delivery that adapts to different working conditions and locations, thereby enhancing portability and outdoor usability.
3Power
If AC power supply input is used for electric gardening tools, then sufficient power can be provided, but the requirement to carry power supply equipment outdoors increases the inconvenience and reduces ease of use
Solution Approach 1:
The power supply requirement is extracted from the AC mains power infrastructure and replaced with a self-contained battery pack system. This extraction allows the tool to operate independently of external electrical infrastructure, eliminating the need to carry power cords or generators outdoors while maintaining sufficient power delivery for gardening tasks.
Solution Approach 2:
The battery pack provides self-service power supply capability, storing energy independently and delivering it directly to the motor and control systems. This self-service approach eliminates dependence on external AC power sources, allowing the tool to be used anywhere outdoors without requiring access to electrical infrastructure or carrying additional power supply equipment.

AI summary
The disclosure provides a multi-purpose portable gardening tool with multiple heads and combinations, belonging to the technical field of electric gardening tools. It solves the technical problems that the existing gardening tools have single function and are inconvenient to carry. The multi-purpose portable gardening tool with multiple heads and combinations includes a main machine, a function head, an extension tube, an extension intermediate head and a function intermediate head; the function head or the extension intermediate head is in spigot joint with a head end of the main machine, a head end of the extension intermediate head is connected to the extension tube having the function intermediate head at a head end thereof, and the function head is in spigot joint with a head end of the function intermediate head. The gardening tool in the disclosure at least includes three function heads, and may further extend more functions and methods of application by combining the function heads to the main machine and combining the main machine to the extension intermediate head, the function intermediate head and the extension tube, so that the gardening tool has more abundant functions to carry out multi-job operations only by one set of equipment, thereby improving convenience of use.
