Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for precision electronic components, such as those with matrix or uni-spiral arrangements, fail to effectively contact irregular surfaces and often result in non-directional particle removal and potential damage, as well as inefficient water distribution and high particle trapping.
Innovation Solution
A bi-spiral cleaning brush with unequally-spaced cleaning beans on a cylindrical carrier, forming bi-spiral paths that push dirt from the center to outward ends in multiple directions, enhancing water distribution and contact surface area for improved cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cleaning units are arranged in a matrix formation with flat top surfaces, then manufacturing is simplified, but contact effectiveness with irregular surfaces deteriorates
Solution Approach 1:
The cleaning units are designed with cambered (curved) top 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.
2Stability of the object's composition
If cleaning units are arranged in a matrix formation, then structural regularity is achieved, but directional cleaning capability deteriorates
Solution Approach 1:
The patent transitions from a symmetric matrix arrangement to an asymmetric spiral arrangement of cleaning units. This asymmetric spiral configuration enables directional pushing of particles from the center outward, providing effective transverse cleaning capability while maintaining structural coherence.
3Productivity
If a uni-spiral cleaning arrangement is used, then cleaning directionality is improved, but water distribution uniformity deteriorates
Solution Approach 1:
The cleaning brush is divided into multiple independent cleaning units arranged in a bi-spiral pattern rather than a single uni-spiral arrangement. This segmentation creates multiple flow fields that distribute water more uniformly across the cleaning surface while maintaining directional cleaning capability.
Solution Approach 2:
The patent evolves from a uni-spiral (single-dimensional spiral) to a bi-spiral (two-dimensional spiral) arrangement. This dimensional change allows water to be distributed across multiple spiral paths, improving water distribution uniformity while preserving cleaning directionality.
4Reliability
If cleaning units have large contact area, then cleaning effectiveness is improved, but particle trapping increases
Solution Approach 1:
The spiral arrangement of cleaning units creates a predetermined directional flow path from the center outward. This preliminary directional arrangement ensures that particles are systematically pushed away before they can be trapped between cleaning units and components, reducing harmful particle trapping while maintaining effective cleaning contact.
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 bi-spiral arrangement allows for directional dirt removal and enhanced water distribution, reducing particle trapping and achieving high decontamination ratios with a large contact surface, surpassing traditional matrix and uni-spiral devices.
Implementation Method 1
two annular spiral curve paths are formed with the cleaning beans to coil the carrier and extend on the center toward the two outward ends circumferentially; on carrying the carrier by the actuating device to clean an electronic device with the cleaning beans, a solution or cleaning agent attached to the carrier is discharged along the annular spiral curve paths in a plurality of spiral tangential directions

AI summary
A cleaning brush is provided. A cleaning unit comprises cleaning beans fixed on a surface of the carrier in a bi-spiral arrangement. The cleaning beans are arranged in an unequally-spaced manner on center of the carrier along a baseline; and, thus, bi-spirals are formed on the center and coiled in two different outward directions. Two annular spiral curve paths are formed with the cleaning beans as coiling the carrier and extending along the two directions. When the carrier cleans an electronic device, a solution or cleaning agent is discharged along the curve paths in spiral tangential directions. Hence, the bi-spiral cleaning unit obtains positive and negative directions on rotating to create a plurality of flow fields. Dirt is discharged easily with water distribution enhanced as compared to unidirectional spiral cleaning devices while a large contact surface, a good cleaning efficiency, and a high decontamination ratio are achieved.
