Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing draining mechanisms for wire electrodes require a suction device to remove liquid, which is not always feasible or efficient.
Innovation Solution
A draining mechanism that includes a block with a through hole intersecting the gravity direction, a first guide portion, a second guide portion, a gas channel to supply compressed gas, and a discharge hole, allowing dielectric working fluid to flow out under its own weight and be blown off by compressed gas, eliminating the need for a suction device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a suction device is used to remove liquid from the wire electrode, then the liquid removal function is achieved, but the device complexity increases
Solution Approach 1:
The patent extracts the liquid removal function from the complex suction device and implements it through a simplified gravity-based drainage structure. The guide pipe with drainage hole and gas channel allows liquid to drain naturally under gravity, eliminating the need for active suction mechanisms while maintaining effective liquid removal capability.
Solution Approach 2:
The drainage system utilizes the liquid's own weight (gravity) to achieve drainage without external power sources or active pumping. The gas channel introduces compressed gas to assist in blowing liquid off the wire electrode, creating a self-service system that uses the materials already present in the machining environment rather than requiring additional complex equipment.
2Productivity
If a suction device is installed for liquid removal, then the dielectric working fluid can be removed, but the equipment structure becomes more complex
Solution Approach 1:
The patent segments the liquid removal function into two independent components: the guide pipe structure with drainage hole for gravity-based drainage, and the gas channel for compressed gas assistance. This segmentation allows each component to perform its specific function simply, avoiding the need for a complex integrated suction device while maintaining effective fluid removal.
3Ease of operation
If compressed gas is introduced through the gas channel, then liquid adhering to the wire electrode is blown off, but gas consumption increases
Solution Approach 1:
The patent applies partial action by introducing compressed gas only at the specific location where liquid adhesion occurs (through the gas channel in the guide pipe), rather than using excessive gas flow throughout the entire system. This targeted approach achieves effective liquid blow-off while minimizing unnecessary gas consumption.

Function Achieved in This Case
Effectively removes dielectric working fluid from the wire electrode without a suction device, ensuring efficient fluid removal and reducing equipment complexity.
Implementation Method 1
the dielectric working fluid flowing out of the first guide portion is discharged under its own weight through the discharge hole
Implementation Method 2
the dielectric working fluid sticking to the wire electrode is blown off by the compressed gas introduced into the through hole between the first guide portion and the second guide portion
