Compact Chainsaw Layout With Detachable Battery and Stable Standing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chainsaws face challenges in improving working performance and user experience, particularly in terms of compact design, efficient power utilization, and ergonomic handling.
Innovation Solution
The chainsaw design incorporates a compact structure with a brushless direct current motor, a transmission assembly, and a power supply device that allows for a detachable connection, along with ergonomic handles and a support mechanism for stable standing, optimizing the chainsaw's size, power efficiency, and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the chainsaw uses a compact structure with integrated motor and power supply, then the size and portability are improved, but the power output and working performance may be limited
Solution Approach 1:
The chainsaw is divided into modular components: a compact housing containing the motor and transmission, a separate guide plate assembly, and a detachable power supply device. This segmentation allows each component to be optimized independently while maintaining overall compactness and adequate power delivery.
Solution Approach 2:
The power supply device is positioned in a dimensionally optimized arrangement, extending from the housing in a direction that balances center of gravity and allows the chainsaw to stand stably. This spatial arrangement maximizes power capacity within the compact form factor.
2Device complexity
If the motor portion and side handle are disposed on the same side, then the structural complexity is reduced, but the ergonomics and user comfort may be affected
Solution Approach 1:
The handle assembly is designed with differentiated local characteristics: the side handle provides lateral support and control, while the top handle (positioned on the opposite side) provides vertical control and positioning. This asymmetric arrangement optimizes user comfort and control despite the motor and side handle being on the same side.
3Ease of operation
If the chainsaw is designed with a support mechanism for stable standing, then the user experience is improved, but the device complexity increases
Solution Approach 1:
The power supply device serves multiple functions: it provides electrical power to the motor, acts as a counterweight to balance the chainsaw, and functions as a support base that enables the chainsaw to stand stably on its own. This multi-functionality reduces the need for separate support structures.
Solution Approach 2:
The support mechanism is designed to create a stable equilibrium position where the chainsaw naturally stands upright. The center of gravity is positioned such that the chainsaw achieves stable equilibrium when resting on the power supply device, eliminating the need for active stabilization mechanisms.
4Adaptability or versatility
If the chainsaw uses a detachable power supply connection, then the adaptability and ease of maintenance are improved, but the reliability of power connection may be reduced
Solution Approach 1:
The power supply connection is designed with pre-positioned alignment features and guide structures that ensure proper engagement before electrical contact is made. This preliminary mechanical alignment prevents misconnection and ensures reliable electrical contact when the power supply is attached.

AI summary
A chainsaw includes a housing with a body portion and a motor portion disposed on a left or right side of the body portion, a guide plate, a chain, a drive assembly including an electric motor, a power supply device, a top handle, a side handle and a circuit board assembly. The top handle is disposed on and connected to an upper side of the body portion, and the rear portion is located below a handle rear end of the top handle. The side handle is disposed on a same side of the body portion together with the motor portion. The circuit board assembly is disposed in the rear portion of the body portion, and located between the power supply device and the drive assembly in a front and rear direction. An overall length of the chainsaw is smaller than or equal to 230 mm.
