Pet Toothbrush Electrode Head for Faster Plaque Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pets resist toothbrushing, making it difficult to effectively remove dental plaque from their teeth due to their limited patience and resistance, leading to inadequate brushing and potential oral health issues.
Innovation Solution
An electric toothbrush for pets that generates an electric field using a driving signal mixed from an AC and DC signal, featuring electrodes on the toothbrush head and a signal supply module in the handle to create an electric field that weakens dental plaque, allowing for effective biofilm removal and enhanced oral care.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional mechanical brushing is used on pets, then the brushing process can be performed, but pets resist due to limited patience and resistance, resulting in inadequate plaque removal
Solution Approach 1:
The patent replaces the traditional mechanical brushing system with an electromagnetic field-based system. The electric toothbrush uses electrodes that generate electromagnetic waves to disrupt and remove dental plaque without requiring extensive mechanical friction, thereby reducing pet resistance while maintaining effective plaque removal.
Solution Approach 2:
The patent changes the operating parameters by using electromagnetic field frequency and intensity instead of mechanical brushing force and duration. The signal supply module generates specific frequency electromagnetic signals that resonate with plaque structures, causing them to break apart more easily without requiring prolonged brushing sessions that pets find tedious.
2Productivity
If electromagnetic field is applied to weaken dental plaque, then biofilm removal effectiveness is enhanced, but device complexity increases due to signal supply module and electrodes
Solution Approach 1:
The patent integrates multiple functions into the electric toothbrush device. The handle part not only houses the battery but also contains the signal supply module that generates electromagnetic signals. The head part contains both bristles for mechanical cleaning and electrodes for electromagnetic plaque disruption, allowing the device to perform both mechanical and electromagnetic cleaning functions simultaneously.
Solution Approach 2:
The patent employs a nested structure where the electrodes are embedded within the toothbrush head, and the signal supply module is integrated into the handle. The connection lines run through the head body to connect the electrodes to the signal supply module, creating a compact nested arrangement that reduces overall device complexity despite the advanced functionality.
3Productivity
If AC and DC signals are mixed to generate driving signal, then oral care effect is amplified, but energy consumption increases
Solution Approach 1:
The patent uses periodic AC signals combined with DC signals to create a pulsating electromagnetic field that effectively disrupts plaque. The AC component provides periodic energy delivery that resonates with plaque structures, while the DC component maintains a baseline field strength. This periodic action achieves superior plaque removal compared to continuous signals while managing energy consumption through controlled pulse timing.
