Variable Speed Dental Polisher With Dual Heads And Splatter Guard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dental polishers are unstable, uncomfortable, lack variable speed options, and fail to protect users from infectious fluids and adequately clean between teeth and gums, often neglecting gum health.
Innovation Solution
A variable speed tooth polishing system with dual polishing heads, a splatter guard for protection, and interchangeable prophy angles, providing therapeutic gum massage and adjustable speed for different cleaning needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single polishing head is used, then the device structure is simple, but the polisher becomes unstable during vibrating rotation
Solution Approach 1:
The patent combines two polishing heads into a single prophy angle assembly, allowing them to operate simultaneously during dental cleaning. This dual-head configuration provides stability during vibration while maintaining operational simplicity through shared mounting and control mechanisms.
2Stability of the object's composition
If the polisher head is made bulky for stability, then the polisher is more stable, but it becomes uncomfortable for insertion into the mouth
Solution Approach 1:
The patent divides the polishing function into two separate but coordinated heads within the prophy angle assembly. Each head can be optimized for its specific function while the overall assembly maintains a compact profile suitable for oral insertion, balancing stability with comfort.
3Ease of manufacture
If a fixed speed power switch is used, then the device is simple to manufacture, but it cannot accommodate varying cleaning needs of different users
Solution Approach 1:
The patent replaces the fixed-speed power switch with a variable speed control mechanism that allows continuous adjustment of rotational speed. This dynamic control system enables adaptation to different user needs (children, adults, severe cases) while maintaining reasonable manufacturing complexity through standard motor control implementations.
4Device complexity
If no protective barrier is used, then the device structure is simple, but users are exposed to infectious fluids during cleaning
Solution Approach 1:
The patent introduces a splatter guard as an intermediary protective barrier between the polishing operation and the user. This transparent or translucent shield deflects flying droplets and aerosols while maintaining visibility and access, protecting against infectious fluids without significantly complicating the overall device structure.
5Device complexity
If a single polishing head is used, then the device is simple, but it cannot effectively clean between teeth and gums
Solution Approach 1:
The patent merges two polishing heads with different brush configurations into one prophy angle assembly. One head is optimized for tooth surfaces while the other is designed for gum line and interdental areas, enabling comprehensive cleaning of all oral surfaces simultaneously during a single operation.
