Rotatable Dental Touch Screen Support for Cleaning-Safe Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental units with touch screens often require dental care professionals to make unergonomic movements to view or input information, and the cleaning process is cumbersome and prone to accidental activation, compromising hygiene and ergonomics.
Innovation Solution
A dental unit with a rotatable display unit that can be adjusted between a vertical orientation for viewing content and a horizontal or angled orientation for easy input, supported by a mechanism that stabilizes the display in the input position, and an optional locking mechanism to prevent accidental activation during cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the touch screen is accessible for cleaning, then hygiene maintenance improves, but accidental activation during cleaning may occur
Solution Approach 1:
The rotatable display unit can be positioned in orientations that facilitate cleaning access. The rotational capability allows the screen to be moved to positions where cleaning personnel can easily reach and clean the surface without causing accidental touches that would activate the touchscreen.
2Ease of operation
If the display unit is made rotatable to improve ergonomics, then ease of operation improves, but device complexity increases
Solution Approach 1:
A support mechanism with rotational capability is provided to enable the display unit to rotate between orientations. The support is designed to maintain stability in each orientation while enabling smooth transition between them, balancing the added complexity with significant ergonomic benefits.

AI summary
A dental unit includes a support and a display unit with a touch screen. The display unit is connected to the support in such a manner that the display unit is rotatable between a first and a second orientation. The first orientation is suitable for enabling a dental care professional to view content displayed on the touch screen during work on a patient situated in a chair of the dental unit, and thus for displaying content on the touch screen. The second orientation is suitable for enabling a dental care professional to input information by touching the touch screen, and thus for receiving input by means of the touch screen. The support is adapted to support the display unit in the second orientation.
