Solution Overview

Problem

Conventional cutting systems face challenges in achieving clean cuts and preventing overheating during the cutting of hard materials, while also dealing with the inhalation of harmful particles and electrical safety issues due to inadequate cooling and particle containment.

Innovation Solution

A cooled cutting system featuring a rotating cutting disc with a cooling device that forms a cavity filled with coolant, allowing the cutting disc to be submerged and retaining particles within the cavity to prevent inhalation and splashing, while maintaining tool dryness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional cooling systems spray water onto the cutting disc, then the cutting area is cooled, but the cutting tool overheats and particles can be inhaled

Engineering Contradiction:

Improvecutting disc temperatureVSAvoidparticle inhalation and tool overheating

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The cavity acts as an intermediary chamber that contains the coolant and cutting particles. Instead of spraying coolant directly into the environment, the cavity mediates the cooling process by containing both the coolant and generated particles, allowing cooling to occur while preventing particle dispersion and tool overheating through enclosed circulation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system converts the harmful hot particles generated during cutting into a beneficial circulation pattern. The particles that would normally be inhaled are instead contained within the cavity, where they are circulated with the coolant and eventually collected, transforming a harmful byproduct into part of the cooling and particle collection mechanism.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Manufacturing precision

If water is used to cool the cutting disc, then cutting quality improves, but the cutting tool becomes wet and electrical safety is compromised

Engineering Contradiction:

Improvecutting qualityVSAvoidelectrical safety

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

The cavity serves as an intermediary containment chamber that isolates the water-cooling process from the cutting tool's electrical components. By confining the coolant and cutting zone within the cavity structure, the system enables effective water cooling for improved cut quality while preventing water from contacting electrical parts, thus maintaining electrical safety.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If the cutting disc rotates at high speed, then cutting efficiency increases, but the cutting area overheats

Engineering Contradiction:

Improvecutting efficiencyVSAvoidcutting area temperature

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

The system establishes continuous circulation of coolant through the cavity, ensuring uninterrupted cooling of the high-speed cutting disc. The rotational movement of the disc continuously brings fresh portions into contact with the coolant stream, while the cavity maintains continuous coolant flow and particle circulation, preventing overheating even at high cutting speeds that improve productivity.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A cutting system including a rotating cutting disc coupled to a cutting tool of a cutting device, and a cooling assembly for cooling the cutting disc when it is in use. The cooling assembly includes an upper covering that covers at least part of the cutting disc, and a lower base having a main slot to allow the passage of a segment of the cutting disc. A part of the lower base is configured to be supported on a workpiece. The lower base cooperates with the upper covering to form a cavity housing the cutting disc. The cooling assembly also includes cooling means that enables at least part of the cavity to be filled with a coolant, such that at least part of the cutting disc is submerged in the coolant during the cutting process, the coolant being discharged from the cavity through the main slot of the lower base.
