Portable Band Saw Battery Mounting for Balance
Solution Overview
Problem
The weight of batteries in portable band saws adversely affects the operability of the tool, as it can disrupt the balance and ease of use during cutting operations.
Innovation Solution
The battery is strategically positioned within the portable band saw's housing to align its gravity center with the assembly's other elements, ensuring balanced operation and improved handling by mounting it in a way that its weight is effectively utilized for cutting, with a configuration that includes a main and auxiliary handle for better grip and balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery is used as a power source to improve portability, then the portability of the band saw is improved, but the weight of the battery adversely affects the operability of the band saw
Solution Approach 1:
The patent addresses the weight issue by transitioning from a fixed internal battery to a detachable battery system, allowing the battery to be separated from the main body. This dimensional change in the battery's integration level enables users to remove the heavy battery component when portability is not required, thereby improving operability while maintaining portability benefits when the battery is attached.
2Power
If the battery is mounted to provide power, then the power supply function is achieved, but the weight distribution affects the balance and handling of the tool
Solution Approach 1:
The patent implements a detachable battery mounting system that allows the battery to be attached or removed based on operational requirements. This dynamic configuration enables the tool to transition between powered and unpowered states, and allows users to adjust weight distribution by removing the battery when precise balance and handling are prioritized over power supply needs.
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
This configuration enhances the operability of the portable band saw by maintaining balance and improving the effectiveness of the battery's weight in cutting operations, allowing for more efficient and balanced use during workpiece cutting.
Implementation Method 1
the battery has a gravity center that is substantially with a gravity center of an assembly of the other elements of the portable band saw
Data Source
AI summary
A portable band saw has a main housing and a saw band circulating within the main housing. A motor for driving the saw band is disposed within a motor housing that is mounted to the main housing. The main housing defines an opening across which the saw band moves in order to cut a workpiece. A battery for driving the motor is mounted to a motor receiving portion of the motor housing. The motor receiving portion has a width corresponding to the width of the opening and opposing to the opening in the forward and rearward directions.
