Bristle-Free Tooth Cleaning Pad With Segmented Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard toothbrushes can harm teeth by removing enamel along with plaque, necessitating a device that effectively cleans teeth without bristles to prevent enamel damage.
Innovation Solution
A tooth cleaning device with a handle and a pad featuring different shaped protrusions, such as semi-spherical and conical, designed to gently remove plaque without damaging enamel, allowing for flexible material composition and a collapsible design for comfort and effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard bristles are used to remove plaque, then plaque removal effectiveness is improved, but enamel damage occurs
Solution Approach 1:
The invention extracts and removes the harmful bristle element from the tooth cleaning device, replacing it with a bristle-free pad structure that eliminates enamel damage while maintaining plaque removal capability through alternative mechanical action
Solution Approach 2:
The invention changes the physical parameters of the cleaning surface from rigid bristles to a flexible pad with varying protrusion heights, creating a gradient structure that provides effective plaque removal with reduced enamel damage through controlled mechanical action
2Object-affected harmful factors
If gentle cleaning action is used to protect enamel, then enamel preservation is improved, but plaque removal effectiveness decreases
Solution Approach 1:
The cleaning pad is segmented into multiple zones with protrusions of different heights and configurations, allowing different regions to perform specialized functions - some areas provide gentle cleaning for enamel protection while others provide more aggressive action for effective plaque removal
Solution Approach 2:
Different local regions of the pad have different properties - areas with taller protrusions provide more aggressive cleaning for stubborn plaque, while areas with shorter protrusions provide gentler cleaning for enamel-sensitive regions, optimizing both plaque removal and enamel preservation simultaneously

AI summary
A tooth cleaning device comprising a handle, and a pad coupled to the handle, wherein the pad has a front face, a back face and a plurality of side walls. There are a plurality of different areas disposed on the front face of the pad comprising a first area comprising a first set of protrusions, in a substantially semi-spherical shape, and a second area comprising a second set of protrusions in a substantially conical shape. There is also a third area of protrusions formed as a substantially conical shape, and a fourth area of protrusions formed as a substantially semi-spherical shape. The device can be formed as a pad which collapses voluntarily under pressure. The pad can be made from any suitable material such as any type of rubber or plastic.
