Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toothbrushes lack the ability to detect specific conditions or agents in the oral cavity and provide responsive outputs to address them effectively, such as bacteria, caries, or malodor, limiting their effectiveness in providing personalized oral care.
Innovation Solution
A sensor-responsive toothbrush equipped with sensors and output components that detect conditions or agents and provide mechanical, light-based, or chemical outputs to treat or remedy detected issues, such as changing bristle motion, emitting light, or dispensing substances, based on sensor inputs and user-selectable parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional toothbrushes are used, then the device is simple and easy to manufacture, but the ability to detect and respond to oral conditions is lacking
Solution Approach 1:
The toothbrush integrates multiple functions including mechanical brushing, sensing capabilities for detecting oral conditions, and various output mechanisms (light, sound, vibration, chemical dispensing) into a single device. This multi-functionality enables the toothbrush to detect and respond to different oral conditions such as bacteria, caries, and malodor, providing personalized oral care while maintaining a unified device structure.
Solution Approach 2:
The toothbrush incorporates sensors that detect oral conditions and trigger responsive outputs based on the detected conditions. The system continuously monitors the oral environment and adjusts its behavior accordingly, such as emitting light to kill bacteria when bacterial presence is detected or dispensing antimicrobial agents when malodor is sensed. This feedback mechanism enhances the reliability of personalized oral care.
2Adaptability or versatility
If sensors and output components are added to the toothbrush, then the ability to detect and treat oral conditions is improved, but the device complexity increases
Solution Approach 1:
The toothbrush employs movable bristle holders that can change position and orientation in response to sensor inputs. The bristle holders are capable of moving between different configurations to adapt to various oral conditions and treatment requirements. This dynamic capability allows the toothbrush to provide targeted treatments while maintaining a relatively compact device structure through controlled movement rather than fixed complex mechanisms.
Solution Approach 2:
The toothbrush uses various intermediary mechanisms to translate sensor detections into appropriate treatments. For example, light-emitting elements serve as intermediaries to convert electrical signals into light energy for killing bacteria, while chemical dispensing mechanisms act as intermediaries to deliver antimicrobial agents. These intermediaries enable versatile treatments without requiring direct complex interactions between sensors and treatment delivery systems.
3Reliability
If the toothbrush provides multiple output types (mechanical, light-based, chemical), then the effectiveness of treating different oral conditions is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The toothbrush is divided into distinct functional modules including sensing modules, light-emitting modules, chemical dispensing modules, and mechanical brushing modules. Each module can be independently manufactured and tested before assembly. This segmentation allows different specialists to manufacture different components using their respective expertise, reducing overall manufacturing complexity while enabling multiple treatment types.
Solution Approach 2:
The patent combines multiple treatment mechanisms into a single integrated toothbrush device. The light-emitting elements, chemical dispensing systems, and mechanical bristle mechanisms are merged into one device that can deliver multiple types of treatments sequentially or simultaneously. This merging reduces the need for multiple separate devices and allows for coordinated operation of different treatment modalities through a single control system.
Data Source
AI summary
A sensor-responsive toothbrush that can adjust its output or operation depending upon information received by one or more sensors incorporated in the toothbrush or as selected by a user. The information typically relates to certain conditions or the presence of particular substances or agents within or outside of the oral cavity. The sensor-responsive toothbrush also includes one or more responsive output components that provide a responsive output in response to the sensed information. A method of providing an oral care benefit, comprising steps of: activating a toothbrush comprising a sensor; detecting a sensor input with the sensor; and initiating a responsive output from the toothbrush in response to the sensor input.
