Rotation Device Inclined Surface Prevents Removing Unit Collision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rotation devices with recessed portions on their outer surfaces face issues where the removing units, when entering these recessed areas, can collide with the side surfaces and get damaged, leading to potential damage and failure in removing foreign substances effectively.
Innovation Solution
Incorporating an inclined surface at the removing unit or the upstream end that comes into contact with the removing unit to move it outward in the radial direction as the rotator rotates, preventing collision with the recessed portion's side surfaces and ensuring continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the removing unit enters the recessed portion due to the inward load, then the removing unit can effectively contact and remove foreign substances from the outer circumferential surface, but the removing unit may collide with the side surface of the recessed portion and get damaged
Solution Approach 1:
The inclined surface is provided in advance at the upstream end of the recessed portion to guide the removing unit before it enters the recessed portion. This preliminary guiding action prevents the removing unit from directly colliding with the side surface, thereby protecting the removing unit from damage while maintaining its effectiveness in removing foreign substances.
Solution Approach 2:
The inclined surface acts as an intermediary element between the removing unit and the recessed portion. Instead of the removing unit directly contacting the potentially damaging side surface, the inclined surface mediates the interaction by providing a gradual transition that guides the removing unit smoothly into the recessed portion, preventing direct collision and damage.
2Productivity
If the removing unit is applied with an inward load to enter the recessed portion, then foreign substance removal is improved, but the risk of collision and damage to the removing unit increases
Solution Approach 1:
The inclined surface is positioned at the upstream end to provide preliminary guidance before the removing unit fully enters the recessed portion. This preliminary action ensures that even when the removing unit is subjected to inward load for effective foreign substance removal, it is guided along a safe path that prevents collision, thereby maintaining operational continuity.
Solution Approach 2:
The inclined surface serves as a protective intermediary that allows the removing unit to withstand the inward load necessary for effective removal operations without directly colliding with the recessed portion's side surface. This intermediary structure maintains both removal efficiency and operational reliability.

AI summary
A rotation device includes a rotator that includes a recessed portion formed on an outer circumferential surface and that rotates in a predetermined rotation direction, a removing unit that comes into contact with a portion of the outer circumferential surface in a range from an upstream end to a downstream end of the recessed portion in the rotation direction due to rotation of the rotator and that removes a foreign substance that adheres to the outer circumferential surface, an application unit that applies an inward load to the removing unit inward in a radial direction of the rotator, and an inclined surface that is located at the removing unit or the upstream end and that comes into contact with the other of the removing unit or the upstream end to move the removing unit entering the recessed portion due to the inward load outward in the radial direction of the rotator along with rotation of the rotator.
