Toothbrush Bridge Arch Pivot Point Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toothbrush designs face issues with high voltage peaks and undefined pivoting movements due to their connecting sections, leading to potential damage and inconsistent use.
Innovation Solution
A toothbrush with a single bridge-like arch connecting the head and handle sections, featuring a soft, elastic plastic coating and stiffening webs, which defines a pivot point and adjusts deformation properties for precise pivoting and user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single bridge-like arch is used as the connecting section, then the structure is simple and manufacturing is easy, but high voltage peaks occur causing damage risk and breakage
Solution Approach 1:
The connecting section combines a bridge-like arch structure with integrated stiffening webs to create a composite design that maintains simplicity while enhancing structural integrity and eliminating high voltage peaks
Solution Approach 2:
The connecting section is segmented into a bridge-like arch with integrated stiffening webs, dividing the structure into functional zones that distribute stress and prevent concentration of forces
2Adaptability or versatility
If a meandering band section is used as the connecting section, then the toothbrush can deform during use, but there is no clearly defined joint or pivot point resulting in inconsistent pivoting movement
Solution Approach 1:
The connecting section has non-uniform geometry with varying thickness along its length, creating a specific region with concentrated flexibility that serves as a defined pivot point while allowing overall deformation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures a reproducible and safe pivoting movement of the head section relative to the handle section, enhancing user experience and durability by minimizing the risk of damage from high voltage peaks and providing a clear pivot point.
Implementation Method 1
The arch (16) is provided with a coating of a soft-elastic plastic in an area facing the head section
Implementation Method 2
the brush holder is provided with at least one stiffening web beneath the coating
Implementation Method 3
the bridge-like arch, which runs in a known manner in the axial longitudinal direction of the toothbrush with a defined curvature, forms a defined pivot point

AI summary
The invention relates to a toothbrush having a bar-shaped brush carrier of plastic, which has a head section having a set of bristles in the front end region of the brush carrier and a handle section in the rear end region of the brush carrier. The handle section and the head section are connected to each other by means of a connecting section, which, at least in parts, is designed as a strip having an undulating configuration. According to the invention, the undulating configuration comprises only one single bridge-like arc, the vertex of which preferably points toward the top side of the toothbrush bearing the set of bristles.
