Solution Overview

Problem

Existing machine tool systems lack flexibility and adjustability in machining operations, particularly in terms of positioning and cutting depth, due to rigid configurations and heavy weights that make them difficult to transport and use in various machining tasks.

Innovation Solution

A machine tool system with a workpiece support unit and a power tool parting device that includes a cutting strand and guide unit, where the parting device is movably mounted relative to the support unit, allowing for adjustable positioning and pivoting, enabling precise cuts and flexible machining options. The system is designed to be lightweight, with a mass less than 60 kg, and features a drive unit for torque transmission, enabling efficient and versatile machining.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If machine tool systems use rigid configurations for stable machining, then manufacturing precision is improved, but adaptability deteriorates

Engineering Contradiction:
Improvecutting precisionVSAvoidmachining flexibility
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The machine tool system incorporates movable and pivotable components that allow dynamic adjustment of the parting device position and orientation while maintaining stability during operation. The guide unit with guide grooves enables controlled movement along specific paths, providing adaptability without sacrificing machining precision.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The machine tool system is divided into modular components including a separable parting device, guide unit, and workpiece support unit. This segmentation allows each component to be independently adjusted and positioned, enhancing overall system adaptability while maintaining precise relative positioning between components.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If machine tool systems are designed with heavy components for stability, then manufacturing precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvecutting precisionVSAvoidtransportability
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The machine tool system is divided into separable modular components that can be easily assembled and disassembled. This allows the system to be transported in smaller sections and reconfigured for different machining tasks, improving ease of operation and transportability while maintaining precision through precise mating features and guide mechanisms.

Inventive Principle:
Principle #1Segmentation

3Strength

If machine tool systems use fixed configurations for structural stability, then strength is improved, but adaptability deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidpositioning flexibility
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The system employs movable mounting mechanisms that allow the parting device to be positioned and pivoted to different angles while maintaining stable structural connections during machining operations. The guide grooves and bearing elements provide controlled movement paths that preserve structural integrity.

Inventive Principle:
