Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush manufacturing devices require complex and costly mechanisms to align bristle carriers in multiple directions for processing, involving decoupling of chain links and additional guides, which increases effort and complexity.
Innovation Solution
A method and device utilizing a revolving endless chain with pivotably attached chain links and a positioning device that aligns the entire chain link section in both intersecting directions within the processing station, eliminating the need for decoupling and additional guides, allowing the chain to pivot laterally and be folded for precise alignment and reduced effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the chain links are decoupled from each other to allow independent alignment movements, then the alignment precision of bristle carriers is improved, but the device complexity and inertial mass increase
Solution Approach 1:
The chain is divided into individual chain links that can pivot relative to each other at cardan joints, allowing each link to be aligned independently while remaining part of the continuous chain structure
Solution Approach 2:
The chain links are designed with variable geometry through cardan joints, enabling dynamic change in the spatial parameters (angles and positions) of each link to achieve precise alignment without decoupling from the chain
2Adaptability or versatility
If additional guides and alignment mechanisms are added to the holders, then the alignment capability in multiple directions is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
Instead of making the holder complex with multiple guides to achieve alignment, the patent inverts the approach by making the chain links themselves alignable through cardan joints, simplifying the holder to a basic support structure
Solution Approach 2:
The cardan joint structure serves multiple functions: it connects chain links in series, allows pivotal movement in multiple directions, and enables alignment of the bristle carrier, replacing what would otherwise require separate alignment mechanisms
3Stability of the object's composition
If the chain is made rigid to maintain structural stability, then the structural stability is improved, but the mobility and alignment capability of chain links deteriorate
Solution Approach 1:
The chain structure transitions from a rigid configuration to a dynamic one, where chain links can pivot relative to each other through cardan joints, allowing the chain to adapt its shape and position while maintaining structural integrity
Applied Scientific Principles

Function Achieved in This Case
This approach simplifies the construction and operation of the device, reducing alignment effort and maintaining precise alignment of bristle carriers for processing, enabling efficient and cost-effective production of brushes with reduced inertial mass and increased mobility of chain links.
Implementation Method 1
A chain consisting of several chain elements is guided in the guide track, on which holders for brush bodies are attached. The individual chain links are connected to each other via a cardan joint in order to enable the relative movement of the chain links in many spatial directions.
