Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chip evacuation devices lack synchronization with other devices and do not have a cleaning mechanism, leading to inefficient operation and accumulation of chips.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an induction motor is used to drive the chip evacuation device, then the device can operate continuously, but the operation cannot be synchronized with other devices and position control is impossible
Solution Approach 1:
The patent changes the motor type from induction motor to synchronous motor, which fundamentally alters the control parameters. Synchronous motors enable precise position control and synchronization capability while maintaining continuous operation, directly resolving the contradiction between productivity and adaptability
Solution Approach 2:
The patent replaces the traditional induction motor control system with a synchronous motor control system that integrates position sensing and synchronized operation control, enabling the chip evacuation device to coordinate with other machining devices
2Device complexity
If no cleaning device is provided, then the device structure remains simple, but chips accumulate on the device itself reducing efficiency
Solution Approach 1:
The patent implements a self-cleaning function where the chip evacuation device cleans itself by reversing the rotation direction of the screw conveyor to discharge accumulated chips from the hopper and conveyor surfaces, eliminating the need for separate cleaning devices while maintaining structural simplicity
Solution Approach 2:
The patent employs periodic cleaning cycles where the screw conveyor alternates between forward rotation (chip evacuation) and reverse rotation (self-cleaning), creating a rhythmic operation pattern that prevents chip accumulation and maintains efficiency
