Multi-Battery Power Cutter Layout for Stable High-Output Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power cutters often have insufficient output power and operating time due to the use of a single battery pack, and the addition of multiple battery packs increases weight, compromising user maneuverability.
Innovation Solution
A power cutter design featuring multiple detachably attached battery packs that supply electric power to an electric motor, with a grip and main switch configuration that stabilizes the device by positioning the center of gravity close to the grip, allowing for increased output and operating time while maintaining maneuverability through balanced weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple battery packs are attached to increase output power and operating time, then the weight of the power cutter increases, but user maneuverability is degraded
Solution Approach 1:
The power supply system is segmented into multiple detachable battery packs that can be attached to the body. This allows the output power to be increased by adding more battery packs while maintaining the ability to detach them, thus balancing power requirements with maneuverability needs.
Solution Approach 2:
The battery pack configuration is made dynamic and adjustable. Users can attach or detach battery packs based on operational requirements, allowing the power cutter to adapt between high-power modes (with multiple packs) and maneuverability modes (with fewer or no packs), resolving the contradiction between power and ease of operation.
2Duration of action of moving object
If multiple battery packs are attached to extend operating time, then the weight of the power cutter increases, but user maneuverability is degraded
Solution Approach 1:
The power supply is divided into multiple detachable battery packs, allowing users to extend operating time by attaching additional packs when needed, while maintaining the option to use fewer packs for lighter tasks, thus preserving maneuverability when extended operating time is not required.
Solution Approach 2:
The battery configuration allows dynamic adjustment of operating time based on task requirements. Users can attach multiple battery packs for extended operation or detach them for improved maneuverability, making the system adaptable to different working conditions.
3Power
If multiple battery packs are attached to increase output power, then the weight of the power cutter increases, but device stability is affected
Solution Approach 1:
The battery packs are positioned in specific locations on the body with consideration for weight distribution. The design ensures that even when multiple battery packs are attached, their placement maintains a balanced center of gravity, preserving device stability while enabling increased output power.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The power cutter achieves enhanced output power and extended operating time by using multiple battery packs connected in series or parallel, with a stable posture due to optimized weight distribution, ensuring improved user handling.
