Grooved Toothbrush Head with Adhesive Cleaning Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional toothbrushes with nylon-thread bristle structures are not suitable for children or individuals with sensitive oral cavities, as they fail to provide comfort and softness, and struggle to effectively clean tooth enamel, limiting their practicality.
Innovation Solution
The toothbrush structure features a toothbrush head with a groove that houses a cleaning device such as a sponge, non-woven fiber, nylon fiber, plant fiber, functional fabric, or plastic device, secured with glue, offering a soft and comfortable cleaning experience suitable for children and sensitive oral cavities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If nylon-thread bristle structures are used in traditional toothbrushes, then the toothbrush can clean teeth, but it causes discomfort and damage to sensitive oral cavities and children's teeth
Solution Approach 1:
The patent changes the physical parameters of the cleaning element by using foam material with varying density and softness levels. The foam can be designed with different cell structures and material compositions to achieve optimal softness for sensitive oral cavities while maintaining cleaning effectiveness through controlled density and elasticity parameters.
Solution Approach 2:
The patent employs composite material strategies by combining foam base material with embedded functional particles or layers. This allows the cleaning surface to have both the softness of foam for comfort and additional cleaning properties from integrated particles, resolving the contradiction between softness and cleaning effectiveness.
2Ease of operation
If soft bristle structures are used to provide comfort, then user comfort is improved, but the ability to clean dirt on tooth enamel is reduced
Solution Approach 1:
The patent applies local quality by creating zones of different foam densities and softness within the same cleaning surface. Harder foam regions provide mechanical cleaning action for stubborn dirt, while softer regions provide comfort for sensitive areas, allowing both comfort and cleaning effectiveness to coexist in different locations.
Solution Approach 2:
The patent incorporates composite materials by embedding abrasive particles, enzymatic agents, or other functional components within the foam matrix. This enables the soft foam to maintain comfort while the embedded components provide enhanced cleaning capability for tooth enamel.
3Device complexity
If traditional nylon-thread bristles are used, then the toothbrush structure is simple, but the functional versatility and adaptability for different users is limited
Solution Approach 1:
The patent achieves universality by designing the foam cleaning surface to perform multiple functions simultaneously: mechanical cleaning, massaging through elasticity, and potential integration of therapeutic agents. The foam structure can adapt to different pressure levels and cleaning needs, making it suitable for various user groups including children and sensitive individuals.
Solution Approach 2:
The patent utilizes parameter changes by offering foam materials with adjustable density, softness, and elasticity parameters to create different versions suited for specific user needs. This allows the basic foam structure to be customized for infants, children, adults with sensitive gums, or those requiring therapeutic cleaning actions.
