Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dental tools, such as sonic and ultrasonic scalers, are limited in effectively removing stains from teeth, particularly in hard-to-reach areas between teeth, due to their design and operation.
Innovation Solution
A powered tooth stain removal device with a chisel tip and electric motor-driven reciprocating motion, featuring a pointed end for interdental stain removal and a broad cleaning surface for main tooth surfaces, secured by a retaining clip mechanism within a portable base unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sonic or ultrasonic scalers with rapidly vibrating pointed tips are used, then calculus and hard deposits can be removed from tooth surfaces, but the device cannot effectively remove stains from hard-to-reach areas between teeth
Solution Approach 1:
The cleaning device is segmented into multiple functional tips (scaler tip and chisel tip) that can be interchangeably attached to the handpiece. The chisel tip specifically addresses interdental stain removal with its specialized geometry, while the scaler tip handles calculus removal. This segmentation allows the device to effectively address multiple cleaning needs including hard-to-reach interdental areas.
Solution Approach 2:
The chisel tip introduces a new dimensional approach to cleaning by extending functionality into interdental spaces. The curved configuration of the chisel tip at approximately 90 degrees from the longitudinal axis enables it to access and clean surfaces between teeth that traditional linear scaler tips cannot reach, effectively adding a spatial dimension to the cleaning capability.
2Adaptability or versatility
If a powered device with chisel tip and reciprocating motion is used, then stains from both interdental and main tooth surfaces can be removed, but the device structure becomes more complex
Solution Approach 1:
The handpiece assembly serves as a universal platform that can accommodate multiple types of tips (scaler tips and chisel tips) through a standardized mounting interface. The electric motor-driven reciprocating motion mechanism provides a universal driving force for all tip types. This multi-functionality allows a single device to perform both main tooth surface cleaning and interdental stain removal without requiring separate specialized devices.
Solution Approach 2:
The chisel tip is configured with dynamic geometric features including a curved configuration at approximately 90 degrees from the longitudinal axis and a broad cleaning surface. The tip is designed to allow finite linear motions decoupled from the housing, enabling adaptive movement and orientation during operation to effectively clean various tooth surfaces including interdental areas.
3Stability of the object's composition
If the chisel tip is secured to the housing with retaining clips, then the tip remains stable during operation, but the tip cannot accommodate finite linear motions
Solution Approach 1:
The mounting structure incorporates localized flexible features at the interface between the chisel tip and housing. The retaining clips are positioned and configured to provide stable retention while allowing finite linear motions of the chisel tip in the longitudinal axis. This local quality differentiation ensures stability where needed (tip retention) while permitting flexibility where required (longitudinal motion for effective cleaning action).
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 device efficiently removes stains from both interdental and main tooth surfaces with precise control and ease of use, enhancing dental hygiene by effectively addressing the limitations of existing tools.
Implementation Method 1
an electric motor housed within the base unit for driving the chisel tip
Implementation Method 2
The chisel tip operates in a reciprocating motion driven by the electric motor. The reciprocating motion repeatedly moves the chisel tip in a back and forth direction by a finite displacement along the chisel tip's longitudinal axis.

AI summary
An apparatus for tooth stain removal is presented. The invention comprises a powered device with a chisel tip at its distal end, a body at its proximal end and an electric motor housed within the body for driving the chisel tip. The chisel tip has a proximal end removably coupled to the body and an exposed distal end along a generally longitudinal axis. The chisel tip comprises a pointed end on a first side for cleaning area between teeth and a broad cleaning surface on a second side for cleaning the main surface of each tooth. The chisel tip operates in a reciprocating motion driven by the electric motor. The reciprocating motion repeatedly moves the chisel tip in a back and forth direction by a finite displacement along the chisel tip's longitudinal axis.
