Portable Interdental Toothbrush Snap-Fit Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interdental toothbrushes inadequately clean between teeth, causing gum stimulation, bleeding, and bacterial growth, with manual injection of cleaning solution limiting mass production and causing the brush body to shake during use.
Innovation Solution
A portable interdental toothbrush design featuring a cleaning solution tube with an upper assembly protrusion for discharge and a lower injection hole, a brush body with a fixed assembly hole, and a snap-fit injection hole cover for easy solution injection and controlled discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual injection of cleaning solution is used through a small diameter assembly protrusion, then the cleaning solution can be injected, but mass production becomes impossible and the structure becomes complex
Solution Approach 1:
The device is divided into separate components: the cleaning solution tube and the brush body are independently manufactured and then assembled. The injection hole cover is a separate piece that snaps onto the tube, allowing for easy mass production of individual components before final assembly.
Solution Approach 2:
The injection mechanism is simplified by extracting the complex manual injection system and replacing it with a simple snap-fit cover that seals the injection hole. This allows cleaning solution to be injected through a simple opening rather than requiring a complex manual injection apparatus.
2Ease of operation
If the cleaning solution tube is rotated to discharge cleaning solution, then the cleaning solution can be delivered to the brush, but the brush body shakes and cannot brush teeth properly
Solution Approach 1:
The cleaning solution is pre-loaded into the tube during manufacturing. The tube is designed with an injection hole that allows the cleaning solution to be filled in advance before the product reaches the consumer, eliminating the need for complex real-time injection mechanisms during use.
3Device complexity
If the brush body is fixed to the cleaning solution tube during solution discharge, then the structure becomes simplified, but the fixing is incomplete and causes shaking
Solution Approach 1:
The brush body is inserted into and nested within the cleaning solution tube assembly. The tube fits into a receiving space on the brush body, creating a nested structure that provides stable fixation while maintaining simple assembly. The injection hole cover snaps onto the tube, further stabilizing the connection.
