Toothbrush Stimulation Element with Enlarged Head Cross-Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral hygiene devices, such as toothbrushes, lack improved functionality and manufacturing efficiency, particularly in terms of stimulation and massage elements.
Innovation Solution
The design incorporates a stimulation and/or massage element with a trunk and a stimulation head, where the cross-section of the stimulation head is enlarged compared to the trunk, and both are preferably made from a single piece of material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stimulation and massage element is added to the oral hygiene device, then the functionality and comfort are improved, but the device complexity increases
Solution Approach 1:
The stimulation head is integrated directly with the stem to form a single-piece structure, eliminating the need for separate components and complex assembly processes. This merging of parts adds the stimulation function while keeping the device simple and manufacturable using existing bristle fastening methods.
2Adaptability or versatility
If the stimulation head cross-section is enlarged compared to the stem, then the stimulation and massage function is enhanced, but the manufacturing difficulty increases
Solution Approach 1:
The cross-sectional dimensions of the stimulation head are increased relative to the stem to enhance the stimulation function. This parameter change is achieved through a one-piece construction that allows for varied cross-sections along the length of the element, enabling improved functionality while maintaining ease of manufacture through integration.
3Ease of manufacture
If multiple components are used for the stimulation element, then the manufacturing flexibility is improved, but the manufacturing time and complexity increase
Solution Approach 1:
The stem and stimulation head are formed as a single integrated component, allowing both to be manufactured in one process step using existing bristle fastening methods. This eliminates the need for separate manufacturing and assembly operations, thereby improving productivity while maintaining manufacturing flexibility.

AI summary
The invention relates to an oral hygiene product, in particular a toothbrush, comprising at least one application unit (12a-g) which has a base body (14a-f) and at least one stimulation and/or massage element (16a-f) connected to the base body (14a-f), and at least one handle unit (18a) which is connectable to, and in particular permanently connected to, the application unit (12a-g) and which has a handle body. It is proposed that the at least one stimulation and/or massage element (16a-f) comprises a stem (20a-f) and at least one stimulation head (22a-f), wherein the cross-section of the stimulation head (22a-f) is enlarged compared to the cross-section of the stem (20a-f).
