Solution Overview

Problem

Dental units with touch screens face challenges in providing ergonomic working environments for dental care professionals due to difficulties in viewing content and entering information, which often require unergonomic movements and positions, and cleaning is cumbersome and risks accidental input activation.

Innovation Solution

A dental unit with a rotatable display unit connected to a support, allowing the display unit to switch between orientations for easy viewing and inputting, stabilized in the second orientation for ergonomic comfort, and featuring a lockable touch screen for cleaning without accidental activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the touch screen is positioned for viewing content during patient treatment, then content visibility is improved, but entering information becomes difficult and requires unergonomic movements

Engineering Contradiction:
Improvecontent visibilityVSAvoidease of entering information
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The display unit is made rotatable about a rotation axis, allowing it to dynamically change orientation between a first position optimized for viewing content during patient treatment and a second position optimized for entering information. This dynamic adjustment resolves the contradiction by enabling the system to adapt its configuration based on the current operational task.

Inventive Principle:
Principle #15Dynamics

2Illumination intensity

If the display unit is positioned for easy viewing, then content display is improved, but cleaning the touch screen becomes difficult and requires unergonomic movements

Engineering Contradiction:
Improvecontent display visibilityVSAvoidease of cleaning
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The rotatable display unit can be repositioned from its viewing-optimized first position to a cleaning-optimized second position, where the touch screen orientation facilitates easier access for cleaning personnel. This dynamic reconfiguration resolves the contradiction between optimal display positioning and optimal cleaning accessibility.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the touch screen is accessible for input operations, then information entry is improved, but accidental inputs during cleaning may occur interfering with settings

Engineering Contradiction:
Improveease of information entryVSAvoidrisk of accidental input activation
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system uses different spatial positions of the display unit to indicate different operational states. When in the first position, the touch screen is active for input operations. When rotated to the second position, the system indicates that input operations should not be performed, reducing the risk of accidental activations during cleaning while maintaining ease of access when properly positioned for use.

Inventive Principle:
Principle #15Dynamics
