Battery-Mount Cutting Tool Layout for Easier Swapping and Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing handheld electric cutters face difficulties in battery handling and operation due to the integrated battery design, which complicates battery swapping and affects the tool's ease of use, and the design of the base extending in the same direction as the grip creates spaces between the cutting disk and opposing blade, making it hard to cut workpieces in a desired direction.
Innovation Solution
A cutting tool with a motor, a rotary blade driven by the motor, a fixed blade, and a battery mount part with a guide groove for easy battery installation and removal, along with a base design that overlaps the fixed blade to stabilize the cutting operation, ensuring easier handling and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the rechargeable battery is built into the housing, then the structure is integrated and compact, but battery swapping becomes complicated
Solution Approach 1:
The battery system is segmented into a removable battery pack and a battery mount part. The battery pack can be independently removed from the housing without disassembling the entire tool, while the battery mount part remains integrated with the housing. This segmentation allows easy battery swapping while maintaining overall structural integration.
2Device complexity
If the base extends in the same direction as the grip, then the design is compact, but spaces are created between the cutting disk and opposing blade making cutting operations difficult
Solution Approach 1:
The base is designed with an asymmetric configuration where the base main body part overlaps the fixed blade in the left-right direction. This asymmetric positioning eliminates gaps between the cutting disk and opposing blade, ensuring proper alignment and effective cutting operation while maintaining a compact overall design.

AI summary
A cutting tool includes a rotary blade driven by a motor, a fixed blade disposed opposing the rotary blade, a housing holding the motor, and a battery mount part on a rear portion of the housing. The battery mount part has a guide groove that slidably receives a rail of a power tool battery pack. A blade cover is disposed partially around the rotary blade, and a portion or all of the blade cover has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade. A base holds the fixed blade, and a portion or all of the base has a shape in which the farther forward it goes the more it goes toward the side that has the fixed blade, viewed from the rotary blade.
