Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an affordable, consumer-level toothbrush that provides meaningful feedback without requiring a connection to a smartphone and includes ergonomic functionality, addressing the complexity and cost issues of existing high-tech electric toothbrushes.
Innovation Solution
An oral care system with integrated features such as a trend tracker, timer, pressure indicator, and mode selection mechanism, utilizing a control circuit with a power source, trend tracking unit, and user perceptible stimuli to provide feedback during and after oral care sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If high-tech features (motion sensors, cameras, smartphone integration) are incorporated into electric toothbrushes, then feedback quality and oral care improvement are improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates the smartphone integration component from the toothbrush system. The toothbrush provides feedback through its own integrated display and wireless communication to a standalone processor, removing the need for smartphone connectivity while maintaining feedback functionality. This reduces device complexity and cost while preserving essential feedback capabilities.
Solution Approach 2:
The toothbrush handle is designed to perform multiple functions: it contains the motor for brush movement, integrated sensors for detecting brushing parameters, a display for user feedback, wireless communication capabilities, and a rechargeable battery. This multi-functionality consolidates what would otherwise require separate devices, reducing overall system complexity.
2Loss of information
If high-tech features (motion sensors, cameras, smartphone integration) are incorporated into electric toothbrushes, then feedback quality and oral care improvement are improved, but cost increases
Solution Approach 1:
The patent removes the expensive smartphone integration component, significantly reducing manufacturing costs. The toothbrush uses a standalone processor and integrated display instead of requiring smartphone connectivity, eliminating the need for complex wireless communication modules and smartphone partnerships, thereby reducing cost while maintaining feedback quality.
Solution Approach 2:
The patent employs cost-effective components such as a rechargeable battery that can be replaced when depleted, and uses standard wireless communication protocols that are inexpensive to implement. The focus is on providing essential feedback functionality through affordable integrated components rather than expensive high-tech features.
3Adaptability or versatility
If smartphone connectivity is required for feedback, then advanced features are available, but ease of operation and accessibility are reduced
Solution Approach 1:
The patent extracts the dependency on smartphone connectivity from the toothbrush operation. The toothbrush provides all necessary feedback through its own integrated display and wireless communication to a standalone processor, eliminating the need for users to have smartphones or complex apps installed. This significantly improves ease of operation and accessibility for all users.
Solution Approach 2:
The toothbrush system is designed to be self-sufficient, providing feedback and control functions without requiring external smartphone devices. The integrated display and wireless communication enable the toothbrush to operate independently, serving the user's oral care needs without needing additional technology infrastructure.

AI summary
An oral care device having a head with cleaning elements and a handle coupled to the head. The handle may include a selectively rotatable ring arranged between the head and a distal end of the handle that is configured to allow a user to select a desired mode of operation of the oral care device. The handle may include a selectively illuminated light that is configured to display at least one color that visually indicates that certain behaviors, patterns, and/or consistent habits have been performed successfully. The handle may include a processor configured to track a duration of a user's brushing session, a light ring on a bottom surface of the handle, and a pressure sensor. Respective portions of the light ring may be selectively illuminated by the processor to visualize progress toward achieving a predetermined brushing routine time and/or to visualize an over-pressure condition sensed by the pressure sensor.
