Spiral Cleaning Brush for Precision Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for precision electronic components, such as those with matrix arrangements of protrusions or cambered surfaces, fail to effectively contact irregular surfaces and often result in non-directional particle removal and potential damage due to particles being trapped or sprayed uncontrollably.
Innovation Solution
A cleaning brush with a carrier and cleaning unit featuring a spiral arrangement of cleaning beans that form a spiral coiling path, allowing for both vertical and horizontal flow fields to facilitate directional dirt removal and reduce particle trapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cleaning units are arranged in a matrix arrangement with flat surfaces, then the device structure is simple and easy to manufacture, but the cleaning units cannot effectively contact irregular surfaces of precision electronic components
Solution Approach 1:
The cleaning units are designed with cambered (curved) surfaces instead of flat surfaces. This curvature allows the cleaning units to adapt to and effectively contact irregular surfaces of precision electronic components, resolving the contradiction between manufacturing simplicity and contact effectiveness.
2Device complexity
If cleaning units are arranged in a matrix arrangement, then the device structure is simple, but particles are removed non-directionally and may be trapped between cleaning units and components
Solution Approach 1:
The cleaning units are arranged in a spiral pattern instead of a symmetric matrix arrangement. This asymmetric spiral configuration creates directional particle removal flow, preventing particles from being trapped between cleaning units and components while maintaining relatively simple device structure.
3Ease of manufacture
If protrusions are formed into flat planes, then the manufacturing process is simple, but the cleaning effectiveness on irregular surfaces is poor
Solution Approach 1:
The protrusions are formed with cambered (curved) surfaces rather than flat planes. This curvature enables better contact with irregular surfaces of precision electronic components, significantly improving cleaning efficiency while keeping the manufacturing process relatively simple.
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
The spiral arrangement enables efficient directional dirt removal and reduces particle trapping, providing a larger contact surface for effective cleaning of precision electronic components with irregular surfaces while minimizing damage.
Implementation Method 1
the cleaning unit having a spiral form set on a carrier generates a flow field which not only comprises a vertical flow for an object to be cleaned but also a horizontal flow forming a parallel stream

AI summary
A cleaning brush comprising a carrier and a cleaning unit is provided. The cleaning unit comprises a plurality of cleaning beans set on a surface of the carrier in a spiral arrangement. A spiral coiling around the carrier from an end of the carrier to the other end is formed. A spiral curve path is formed to coil the carrier circumferentially by extendedly arranging the cleaning beans. Hence, the present invention uses the cleaning beans of the cleaning unit to be set on surface of the carrier. On rotating in a fixed direction, the spiral cleaning unit generates a flow field which not only comprises a vertical flow for an object to be cleaned but also a horizontal flow forming a parallel stream. Thus, dirt can be removed more easily than by using a traditional matrix cleaning device.
