Solution Overview

Problem

Current dental care unit device holder systems face limitations in identifying and activating devices, especially in closed holders, due to issues with hose geometry and material properties, leading to incorrect activation signals and restricted device order flexibility.

Innovation Solution

The implementation of optical sensors capable of color separation, which utilize color identifiers on device hoses to identify device types and activation states, allowing for flexible device order rearrangement and accurate activation signaling without the need for separate activation identifiers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If microswitch identification is used to detect device placement, then activation function is enabled, but it cannot be used in closed holders where hoses roll through

Engineering Contradiction:
Improveactivation functionVSAvoidholder type compatibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent replaces mechanical identification methods (microswitches) with optical identification methods. Optical sensors detect color identifiers on devices regardless of holder type, enabling both open and closed holders to achieve reliable device detection and activation without the limitations of mechanical contact-based systems.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces color identifiers as an intermediary element between the device and the identification system. These visual markers serve as a universal interface that optical sensors can detect in both open and closed holder configurations, mediating the identification process across different holder types.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If inductive or capacitive identification is used, then it functions in open and closed holders, but it requires devices to be specially designed with electrically conductive properties

Engineering Contradiction:
Improveholder type compatibilityVSAvoiddevice design requirements
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent employs color identifiers on devices that can be detected by optical sensors. This approach requires no special electrical properties or complex manufacturing modifications to the devices themselves, making it easier to manufacture while maintaining compatibility with both open and closed holder types.

Inventive Principle:
Principle #32Color changes

3Measurement precision

If prior art optical methods are used, then identification is achieved in open holders, but they cannot reliably detect devices in closed holders

Engineering Contradiction:
Improvedevice detection accuracyVSAvoidholder type compatibility
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent places color identifiers at specific locations on devices (such as on the hose portion that remains visible in closed holders or on the device body in open holders). This localized placement ensures that optical sensors can detect the identifier regardless of whether the holder is open or closed type, achieving both precise detection and universal compatibility.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility

If device order in console is changed, then flexibility is improved, but identification signals may become incorrect without reprogramming

Engineering Contradiction:
Improvedevice order flexibilityVSAvoidactivation signal accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements a system where optical sensors continuously detect color identifiers on devices in the console, and the control unit receives feedback about device positions and types. This feedback mechanism allows the system to automatically update identification signals when device order changes, maintaining reliability without requiring manual reprogramming.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent pre-programs the control unit with information about different device types and their corresponding activation signals. When a device is placed in the console, the system preliminarily identifies it via color detection and automatically selects the correct activation signal, preparing the appropriate response before the device is actually activated.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a dental care unit and its device holder unit. In the device holder unit, there are device- places and the device-places are arranged such that the device holder unit can be fitted with different and/or different types of devices. Preferably, in a device hose, or in a device connected to a hose, there is a colour identifier, and the device-places of the device holder unit are provided with optical sensors capable of colour separation, which sensors are arranged to identify the colour identifier in question. The invention enables implementing the device order of the console such that places of the devices in the console are freely changeable.
