Solution Overview

Problem

Conventional electrode cutting apparatuses face challenges in maintaining consistent electrode cutting quality due to wear and tear of cutters, generation of burrs, and difficulty in adjusting clearance and parallelism between the upper and lower cutters, leading to increased defects and complex assembly processes.

Innovation Solution

A cartridge-type electrode cutting apparatus with detachable upper and lower units and a guide portion for setting and fixing clearance and parallelism before assembly, allowing for easy adjustment and mounting to a main body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the upper cutter and lower cutter are directly fastened to the main frame step by step, then the assembly is complete, but the clearance and parallelism between cutters cannot be easily adjusted and the assembly process is complicated

Engineering Contradiction:
Improveease of assemblyVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The electrode cutting apparatus is divided into an upper unit (including upper cutter and upper holder) and a lower unit (including lower cutter and lower holder) that can be assembled separately and then mounted to the main frame as a complete cartridge assembly. This segmentation allows clearance and parallelism to be adjusted during the unit assembly stage before final installation, simplifying the overall assembly process while ensuring cutting precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guide portion is designed to enable preliminary adjustment of clearance and parallelism between the upper and lower cutters during the assembly of the upper and lower units, before the complete cartridge is mounted to the main frame. This preliminary action ensures that cutting precision is established in advance, avoiding the need for complex adjustments after installation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the upper cutter is inclined due to side pressure and difference in distance, then the cutting can proceed, but the upper frame must be minutely adjusted using headless bolts which is complicated and time-consuming

Engineering Contradiction:
Improvecutting operationVSAvoidadjustment time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The guide portion acts as an intermediary mechanism between the upper and lower units, providing a structured way to adjust and maintain the positional relationship between the upper cutter and lower cutter. Instead of directly adjusting the upper frame with headless bolts, the guide portion mediates the alignment process, enabling easier and faster adjustment of cutter inclination and clearance.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Duration of action of stationary object

If the clearance between upper cutter and lower cutter is gradually increased due to cutter wear, then the cutters can be used repeatedly, but the cutting quality deteriorates and defects increase

Engineering Contradiction:
Improvecutter usage durationVSAvoidcutting quality
Core Design Contradiction:
Duration of action of stationary objectVSManufacturing precision

Solution Approach 1:

The cartridge-type electrode cutting apparatus is designed to be detachable and replaceable as a complete unit. When the cutters wear out and clearance increases, the entire cartridge assembly can be quickly removed and replaced with a fresh one, rather than attempting to adjust or repair the worn cutters in place. This dynamic replacement approach maintains cutting quality while extending the overall system usage duration.

Inventive Principle:
Principle #15Dynamics
