Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanized washing brushes for vehicles and aircrafts face challenges such as complex and time-consuming fixation of flexible elements, high storage and transport costs, inability to easily replace worn-out components, and uniform cleaning action that cannot be intensified in specific areas.
Innovation Solution
A brush device with flexible support and fringed bands that can be quickly and safely fixed using elongated body means with protruding arms, allowing for single-layer or multi-layer bands to be easily added or replaced, assembled with minimal tools, and enabling enhanced cleaning action in specific areas without disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional fixing methods are used for flexible elements, then the brush can be assembled, but the assembly process is very complex and time-consuming requiring skilled workers
Solution Approach 1:
The brush device is divided into separable components: a support structure, flexible elements (fringed bands), and fixing means. This segmentation allows each component to be manufactured independently and assembled in a simplified manner, reducing both assembly complexity and the skill level required while maintaining secure attachment of flexible elements to the support.
2Productivity
If traditional fixing methods are used, then the brush can be assembled, but it requires a lot of time by skilled workers resulting in high costs
Solution Approach 1:
The fixing means are designed to enable preliminary preparation of components before final assembly. The support structure and flexible elements can be prepared separately with attachment features already in place, allowing for rapid final assembly without time-consuming on-site fixing operations, thereby increasing productivity and reducing assembly time.
3Adaptability or versatility
If traditional brush designs are used, then the brush provides homogeneous cleaning action, but it cannot intensify cleaning in specific areas
Solution Approach 1:
The brush device incorporates flexible elements with varying characteristics in different zones. Certain areas have denser or more robust fringed bands to provide intensified cleaning action for heavily soiled regions, while other areas have lighter configurations for gentle cleaning. This local differentiation allows the brush to adapt to varying cleaning requirements across different surfaces without compromising overall ease of operation.
4Quantity of substance
If brushes are assembled with fixed flexible elements, then the brush is ready for use, but storage and transport costs are high due to bulky pre-assembled brushes
Solution Approach 1:
By segmenting the brush into support structure, flexible elements, and fixing means, the components can be stored in a compact, disassembled state requiring minimal storage space. Assembly is simplified through the designed attachment features that enable quick connection without complex procedures, thus reducing storage and transport costs while maintaining ease of manufacture.
5Ease of repair
If traditional brush designs are used, then the brush is complete, but the user cannot easily replace worn or damaged bristles
Solution Approach 1:
The fixing means are designed to provide a dynamic, reversible connection between flexible elements and the support structure. This allows flexible elements to be easily removed and replaced when worn or damaged, while maintaining secure attachment during normal operation. The system transitions from a static, permanent fixation to a dynamic, replaceable connection, enhancing both ease of repair and long-term reliability.
