Cutting Cover Guide Structure for Coolant Drip Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cutting apparatuses with coolant systems face contamination issues when the cover is opened after cutting, as coolant adhering to the cover drips out and contaminates adjacent areas.
Innovation Solution
A cutting apparatus design where the guide serves as a liquid passage to return coolant to the machining space when the cover is closed, ensuring that any coolant on the cover drips back into the machining space when opened, preventing external contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coolant system is used during cutting, then friction is reduced and cooling effect is achieved, but coolant adhering to the cover drips out and contaminates adjacent areas
Solution Approach 1:
The patent converts the harmful dripping coolant into a beneficial feature by designing the guide structure to redirect coolant droplets back into the machining space. The guide extends from the cover toward the machining space, creating a liquid passage that captures dripping coolant and returns it to the workspace, transforming the contamination problem into a coolant recovery solution.
Solution Approach 2:
The guide acts as an intermediary element between the cover and the machining space. It serves as a mediating structure that intercepts coolant droplets attempting to escape from the cover and redirects them back into the machining space, preventing direct contamination of the adjacent area while maintaining the coolant system's effectiveness.
2Ease of operation
If the cover is opened after cutting, then workpiece access is enabled, but coolant adhering to the cover drips out and contaminates the surrounding area
Solution Approach 1:
The guide structure is pre-configured on the cover before opening occurs. This preliminary arrangement ensures that when the cover is opened after cutting, the guide is already in position to intercept and redirect any coolant droplets that may be adhering to the cover, preventing contamination before it can occur.
Solution Approach 2:
The guide transforms the potentially harmful dripping coolant into a beneficial feature by redirecting it back into the machining space. When the cover is opened, any coolant on the cover is channeled through the guide structure back into the workspace, converting a contamination risk into a coolant recovery mechanism that maintains cleanliness in the surrounding area.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively keeps the surrounding area clean by ensuring coolant droplets fall into the machining space when the cover is opened, reducing the need for cleaning and enhancing user convenience.
Implementation Method 1
With the cover in the closed state, the guide of the cutting apparatus serves as a liquid passage along which the coolant is returned to the machining space

AI summary
A cutting apparatus 10 includes a case body 12 provided with an opening 180 and internally including a machining space 19, and a cover 20 attached to the case body 12. The cover 20 changes between an open state where the cover 20 uncovers the opening 180 and a closed state where the cover 20 covers the opening 180. The cover 20 includes a cover body 20A and a guide 74 extending toward or into the machining space 19 from the cover body 20A. With the cover 20 in the closed state, an extremity 74E of the guide 74 is located below a lower end 18E of the opening 180. During a transition from the closed state to the open state, the extremity 74E is located within the machining space 19 or overlaps with the opening 180 when viewed in the front-rear direction of the machining space 19.
