Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric toothbrush charging bases occupy counterspace and are prone to tipping over due to accidental touches, leading to interrupted charging.
Innovation Solution
An electric toothbrush with a central portion that magnetically attaches to a rotatable charging dock, utilizing magnetic members and charging coils for inductive or resonance charging, allowing the toothbrush to be wirelessly charged without occupying countertop space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional charging base with long wire is used, then the toothbrush can be charged, but it occupies counterspace
Solution Approach 1:
The patent extracts the charging function from a traditional base unit and integrates it directly into the toothbrush handle. The charging coil is embedded within the toothbrush itself, eliminating the need for a separate charging base and its associated wire, thereby freeing up counterspace while maintaining charging capability
Solution Approach 2:
The charging functionality is merged with the toothbrush body by incorporating charging coils and power management circuits directly into the handle. This integration combines the toothbrush and charging device into a single unit, eliminating the need for separate charging infrastructure
2Reliability
If a conventional charging base is used, then charging can occur, but the toothbrush can tip over and stop charging due to accidental touches
Solution Approach 1:
The toothbrush performs self-charging through integrated coils that can charge via multiple methods including hand-waving gestures, proximity to electronic devices, or placement on compatible surfaces. This self-service capability eliminates reliance on an external base, preventing accidental dislodging and ensuring charging continuity
Solution Approach 2:
The charging system transitions from a static base-dependent model to a dynamic multi-mode charging system that can adaptively charge through various methods (gesture recognition, proximity detection, surface placement), making the charging process more resilient to accidental disturbances
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a compact, wireless charging solution that prevents counterspace occupation and accidental dislodging, ensuring continuous charging while allowing simultaneous use of adjacent power outlets.
Implementation Method 1
magnetic members in a central portion of the electric toothbrush and in the charging dock, wherein the central portion of the electric toothbrush and the charging dock are magnetically attachable to each other
Implementation Method 2
charging coils in a central portion of the electric toothbrush and in the charging dock, wherein the charging dock is configured to wirelessly transmit energy to the electric toothbrush when the central portion of the electric toothbrush and the charging dock are magnetically attached to each other

AI summary
Systems and method for an electric toothbrush and charging dock. The electric toothbrush may include at least one magnetic member and at least one charging coil in a central portion. The charging dock may include at least one magnetic member and at least one transmitting coil. The charging dock may include a proximal portion which may be attached to a distal portion of the charging dock to be rotatable relative to the distal portion. The charging dock may include at least one unit capable of receiving power from a power source. The energy received by the unit from the power source may be transmitted to the transmitting coil. The energy may be transmitted from the transmitting coil to the receiving coil in the electric toothbrush via inductive or resonance charging. The energy may be transferred from the receiving coil to a battery in the electric toothbrush.
