Portable Interdental Toothbrush with Integrated Cleaning Solution Tube
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interdental toothbrushes often stimulate gums, lead to frequent bleeding, and have inadequate plaque removal, with issues of bacterial growth and inconvenient handling of cleaning solutions, and existing solutions are either complex or costly, limiting their practicality and continuous use.
Innovation Solution
A portable interdental toothbrush design where the brush body's fixing portion is press-fitted into a cleaning solution tube, maintaining a pressure difference to prevent solution discharge, allowing for easy manufacturing, low cost, and convenient use with controlled solution delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a lid containing cleaning solution is coupled inside the toothbrush, then the toothbrush can be soaked with cleaning solution, but the cleaning solution can be discharged outside if the lid is open and it is troublesome to repeatedly put in and pull out the toothbrush in the lid
Solution Approach 1:
The cleaning solution tube is directly integrated with the brush body, merging the storage function into the brush structure itself. The tube is formed as an integral part of the brush handle, eliminating the need for a separate lid or container that needs to be opened and closed.
Solution Approach 2:
The brush body automatically receives cleaning solution through its own structure. When the user applies pressure to the brush, the cleaning solution is dispensed directly to the brush bristles without requiring manual intervention to open lids or transfer solution.
2Reliability
If a storage tank with discharge hole, spring, coupling socket, nozzle, and nozzle cap is used, then the cleaning solution can be controlled to discharge, but the structure is complicated and the manufacturing cost is high
Solution Approach 1:
The invention extracts and eliminates unnecessary components from the cleaning solution discharge system. Instead of using springs, coupling sockets, nozzles, and caps, the patent uses a simple tube structure with a discharge hole that opens directly, removing complex mechanisms while maintaining discharge control through direct user pressure on the brush.
3Reliability
If the cleaning solution is stored in a complex structure with multiple parts, then the discharge can be controlled, but the manufacturing cost is high and mass production is difficult
Solution Approach 1:
The brush is divided into functional segments: the brush body with integrated cleaning solution tube, the discharge hole positioned at the tip, and the reservoir space within the handle. This segmentation allows each part to be manufactured independently and assembled simply, facilitating mass production while maintaining controlled discharge functionality.
4Ease of manufacture
If a simple brush structure is used, then the manufacturing cost is low, but the gums become stimulated and bleeding occurs frequently
Solution Approach 1:
The brush applies cleaning solution locally and directly to the interdental spaces where it is needed. The discharge hole is positioned to deliver solution precisely to the brush bristles contacting the teeth and gums, providing targeted cleaning that reduces the need for aggressive brushing motions that cause gum stimulation.
