Innovation Solution
A dual-purpose electric toothbrush head with a toothbrush handle and head featuring a nozzle and water trough for rinsing, integrated with a main engine for water pumping, allowing for simultaneous tooth surface cleaning and oral cavity rinsing, featuring a stable and convenient design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a transmission assembly is used to drive the toothbrush head to vibrate through rapid rotation of the motor, then the cleaning effect is improved, but the internal structure becomes unstable and prone to damage
Solution Approach 1:
The patent removes the transmission assembly from the electric toothbrush structure. Instead of using a transmission assembly to convert motor rotation to vibration, the toothbrush head is directly coupled to the motor shaft, eliminating the intermediate transmission components that caused structural instability and damage.
Solution Approach 2:
The patent divides the toothbrush into functional modules: the motor assembly with direct drive, the toothbrush head with bristles, and the handle with water delivery system. This segmentation allows each component to perform its specific function independently, improving overall reliability while maintaining cleaning effectiveness.
2Productivity
If traditional electric toothbrush structure is used, then tooth surface cleaning is achieved, but diastema and oral cavity cannot be rinsed
Solution Approach 1:
The patent integrates multiple functions into the electric toothbrush: the bristle assembly performs tooth surface cleaning, while the water delivery system with nozzle and water trough enables rinsing of diastema and oral cavity. This multi-functionality allows a single device to address various oral hygiene needs.
Solution Approach 2:
The patent introduces water as an intermediary substance to enable rinsing functionality. The water delivery system uses water flow as a mediator to clean areas that bristles alone cannot reach, such as diastema and oral cavity surfaces, complementing the mechanical cleaning action of the bristles.
3Manufacturing precision
If multiple assembly parts are used in electric toothbrush, then manufacturing precision can be maintained, but production cost and processing complexity increase
Solution Approach 1:
The patent merges multiple components into integrated assemblies: the motor and toothbrush head are directly coupled without intermediate transmission parts; the water delivery system integrates the nozzle, water trough, and water inlet chamber into a unified structure. This merging reduces the total number of assembly parts while maintaining manufacturing precision.
Solution Approach 2:
The handle integrates multiple functions into a single component: it contains the water inlet chamber, houses the water delivery system, and provides the ergonomic grip. This multi-functional design reduces the number of separate parts needed, simplifying assembly while maintaining precision.
