Color-Coded LED Dental Device Status Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental material treatment devices face challenges in effectively communicating the operating state of multiple devices, especially in large dental laboratories, due to reliance on digital displays that are expensive, difficult to read in varying light conditions, and prone to mistakes when multiple devices are operated simultaneously, and acoustic signals that can be confusing.
Innovation Solution
The implementation of a display system using multiple light diodes with color signals (red, yellow, green, or blue) on a black glass disk, allowing for clear visualization of operating states across multiple devices, with the ability to modulate light parameters and change colors to indicate different states, ensuring visibility regardless of ambient light and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If digital displays are used to signal operating states, then information can be provided, but the displays are expensive and difficult to read in varying light conditions
Solution Approach 1:
The patent uses color-coded light signals (red, yellow, green, blue) to indicate different operating states of dental devices. Each color corresponds to a specific state, allowing operators to quickly understand device status without complex digital displays. This simple color-coding system is cost-effective and maintains high visibility under varying ambient light conditions.
Solution Approach 2:
The patent replaces complex digital display systems with simple optical signaling using light-emitting diodes (LEDs). This substitution eliminates the need for expensive digital screens while providing clear, distance-visible signals that work reliably in different lighting environments.
2Loss of information
If digital displays are used to signal operating states, then information can be provided, but the displays are difficult to read from a distance and protected information is hard to detect
Solution Approach 1:
The patent employs brightly colored light signals that can be detected from a distance. The use of distinct colors (red, yellow, green, blue) creates high visual contrast that remains visible across the dental laboratory space, allowing operators to monitor multiple devices remotely without straining to read small digital displays.
3Loss of information
If acoustic signals are used to indicate operating states, then information can be transmitted, but the signals are easily mistaken for alarms and the alarm function is limited
Solution Approach 1:
The patent uses distinct color codes to represent different operating states, creating an unambiguous visual language that eliminates confusion between information signals and alarm signals. Operators can immediately distinguish between normal operational colors and alarm conditions, maintaining reliable communication without the misinterpretation issues associated with acoustic signals.
4Loss of information
If tele-indication displays are used, then operating temperature and time can be signaled, but visibility depends greatly on ambient illumination
Solution Approach 1:
The patent replaces passive digital displays that rely on ambient light with active light-emitting diodes that generate their own illumination. These self-luminous signals maintain consistent visibility regardless of whether the environment is brightly lit or dimly lit, eliminating the dependency on ambient illumination conditions.

Data Source
AI summary
A display associated with a treatment device for dental material, with which at least one operating state of the device can be displayed. The display is a function of the operating state of the device. The display shows different operating states of the treatment device exclusively with the aid of color signals, whereby each color is associated with an operating state of the device.
