Oral Cleaning Head Motion Control With Random Cleaning Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral cleaning tools, such as electric toothbrushes, lack flexibility in adapting to the diverse conditions of different users' oral cavities, failing to provide personalized cleaning and often causing discomfort due to fixed vibration frequencies and sweeping patterns.
Innovation Solution
An oral cleaning device with a grip portion, driving unit, and cleaning head that utilizes a random cleaning angle generated by a control unit, allowing for variable vibrations and sweeps based on a random angle generation algorithm, enabling the device to adapt to individual oral cavity conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an oral cleaning tool performs high-frequency reciprocating vibrations according to a preset frequency, then the cleaning action is simple and reliable, but the device cannot flexibly adapt to different oral cavity conditions and cannot meet personalized oral care demands
Solution Approach 1:
The patent applies dynamics by transforming the static, fixed-frequency vibration into a dynamic, variable-frequency vibration system. The driving unit adjusts vibration frequency and cleaning angle in real-time based on random cleaning angle signals, enabling the cleaning head to adapt to different oral cavity conditions while maintaining system reliability through controlled randomness.
Solution Approach 2:
The patent implements parameter changes by modifying key operational parameters including vibration frequency and cleaning angle. The control unit generates random cleaning angle signals that cause the driving unit to vary these parameters dynamically, allowing the device to adapt to personalized oral care needs without requiring complex user input or sensing systems.
2Adaptability or versatility
If an oral cleaning tool uses a single cleaning mode with preset frequency, then the device structure is simple, but it neglects different conditions of to-be-nursed oral cavities and cannot provide personalized cleaning
Solution Approach 1:
The patent applies self-service by enabling the device to automatically adjust its cleaning parameters without external intervention. The control unit autonomously generates random cleaning angle signals and adjusts vibration frequency based on pre-set ranges, allowing the device to provide personalized cleaning adaptation on its own without requiring complex user feedback loops or additional sensors.
3Ease of operation
If an oral cleaning tool performs fixed sweeping patterns, then the cleaning path is predictable and easy to control, but it causes discomfort and cannot adapt to individual oral cavity conditions
Solution Approach 1:
The patent applies dynamics by transforming fixed, predictable sweeping patterns into dynamic, variable cleaning paths. The random cleaning angle signals cause the cleaning head to follow unpredictable yet controlled trajectories, enhancing user comfort by avoiding repetitive mechanical sensations while maintaining ease of operation through automated control.
