Solution Overview
Problem
Existing machine tool systems lack portability and versatility in machining workpieces, particularly in making precise and reliable cuts with a portable machine tool that can be easily transported and operated without a transport machine, while maintaining effective force and torque transmission.
Innovation Solution
A portable machine tool system with a machine tool housing, a coupling device, and a support unit that allows for relative movement between the support unit and the machine tool housing, featuring a drive unit, cutting strand, and guide unit forming a closed system, enabling precise and versatile machining with a lightweight, electrically operated plunge-cut saw or similar tool, capable of pivoting and adjusting to different angular positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the machine tool is made portable and lightweight, then portability and ease of transport are improved, but force and torque transmission capability deteriorates
Solution Approach 1:
The support unit is designed to be pivotable relative to the machine tool housing, allowing dynamic adjustment of the cutting angle and position. This pivotable connection enables the portable machine tool to adapt to different workpiece geometries and cutting requirements while maintaining lightweight construction, resolving the contradiction between portability and machining versatility
2Stability of the object's composition
If the support unit is fixed to the machine tool housing, then structural stability is improved, but adaptability to different cutting angles and positions deteriorates
Solution Approach 1:
The support unit is designed to be pivotable relative to the machine tool housing, allowing dynamic adjustment of the cutting angle and position. This pivotable connection enables the portable machine tool to adapt to different workpiece geometries and cutting requirements while maintaining structural stability during operation
Solution Approach 2:
The locking device allows the operator to fix the support unit at different angular positions relative to the machine tool housing. By changing the angular parameter of the support unit, the system can adapt to various cutting angles and positions while maintaining stability when locked, resolving the contradiction between structural stability and adaptability
3Manufacturing precision
If the cutting depth is not consistent, then machining precision deteriorates, but the complexity of maintaining constant cutting depth increases
Solution Approach 1:
The patent includes a depth marking on the machine tool housing that indicates the cutting depth. This visual indicator allows the operator to easily set and maintain consistent cutting depth without complex control mechanisms, resolving the contradiction between machining precision and device complexity by using a simple visual reference system
