Interdental Cleaning Element With Twisted Wire Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interdental cleaning elements with bristle filaments and dental floss threads arranged on opposite sides of a rod-shaped base cannot act simultaneously, limiting their cleaning effectiveness in interdental spaces.
Innovation Solution
An interdental cleaning element with a rod-shaped base featuring twisted wire elements that house both bristle filaments and dental floss threads at the same height, allowing them to be used together in a single position, with the dental floss thread material providing multiple contact surfaces for enhanced cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bristle filaments and dental floss threads are arranged on opposite sides of a rod-shaped base, then the structure is simple and manufacturing is easy, but the two cleaning elements cannot act simultaneously at the intended point
Solution Approach 1:
The patent combines bristle filaments and dental floss threads at the same position on the rod-shaped base, allowing both cleaning elements to act simultaneously at the intended point. This is achieved by attaching both types of cleaning elements to the same location rather than opposite sides, enabling their combined cleaning action during a single insertion.
Solution Approach 2:
The invention transitions from a one-dimensional arrangement (opposite sides along the length of the base) to a three-dimensional configuration where multiple cleaning elements are stacked or arranged in space at the same position, allowing simultaneous action without increasing the overall length of the device.
2Productivity
If multiple cleaning elements are attached at the same position on the rod-shaped base, then cleaning effectiveness is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent attaches multiple cleaning elements to the rod-shaped base during the manufacturing process before final assembly, allowing simultaneous cleaning action to be achieved without requiring complex post-manufacturing assembly steps. The cleaning elements are pre-positioned and secured to the base in a controlled manufacturing environment.
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
This configuration enables simultaneous action of both cleaning elements, improving cleaning efficiency in interdental spaces by providing multiple contact surfaces with the dental floss thread material while maintaining the effectiveness of bristle filaments.
Implementation Method 1
the dental floss thread material used in the interdental cleaning element according to the invention is attached to the rod-shaped base as a thread, with each of the threads being composed of a large number of individual very fine threads which are twisted or woven together, for example. Such a dental floss thread composed of very fine threads fans out during use, so that the individual very fine threads of the dental floss thread material offer multiple contact surfaces when using the interdental cleaning element in the interdental space
Implementation Method 2
the rod-shaped base has wire elements which are twisted against one another and clamp the first and second cleaning elements between them
