Cutting Machine Battery Placement for Dust Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting machines generate dust during operation, which can negatively affect components like motors and batteries, leading to reduced performance and reliability.
Innovation Solution
A cutting machine design where the battery is positioned on the opposite side of the motor in the width direction, with a power control unit arranged above the motor, and a holder system for easy attachment and detachment, reducing dust exposure and improving weight balance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the motor and battery are arranged close to the blade for compact design, then the machine structure is simplified, but the electrical components are exposed to dust generated during cutting work
Solution Approach 1:
The patent applies dimensional separation by arranging the motor and battery in different spatial dimensions relative to the blade. Specifically, the motor is positioned above the blade while the battery is positioned below the blade, creating a vertical separation that distances electrical components from the dust generation zone at the cutting interface. This spatial reconfiguration in the vertical dimension effectively reduces dust exposure while maintaining compact overall machine structure.
2Object-affected harmful factors
If the battery is positioned away from the motor, then dust influence on electrical components is reduced, but the machine's weight balance and stability may be affected
Solution Approach 1:
The patent employs asymmetric positioning of electrical components relative to the blade, with the motor placed above and the battery placed below. This asymmetric arrangement creates a balanced weight distribution that compensates for the separation distance between components. The strategic asymmetric placement ensures that the center of gravity remains stable while effectively distancing the battery from dust exposure zones, thus maintaining machine stability despite component separation.
