Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If extrusion process is used to produce U-shape channels on metal core, then the channels can be formed efficiently, but the tooling costs are extremely expensive and limited in size
Solution Approach 1:
The brush is divided into separate modular components: a core element and interchangeable brush element strips. The U-shape channels are formed as integral parts of the core element through injection molding, eliminating the need for separate extrusion tooling. This segmentation allows different brush configurations to be produced using the same core tooling by simply changing the brush element strips.
Solution Approach 2:
The core element with its U-shape channels is designed as a universal component that can work with multiple types of brush element strips. The standardized channel geometry allows different brush configurations (different numbers, types, and arrangements of brush elements) to be produced using the same core, reducing tooling requirements and enabling multi-functionality.
2Adaptability or versatility
If welding process is used to attach U-shape channels to core, then flexibility in channel placement is improved, but skilled labor and expensive equipment are required
Solution Approach 1:
The U-shape channels and the core are merged into a single integral component through injection molding. This eliminates the need for separate welding operations to attach channels to the core. The channels are formed directly as part of the core structure, reducing manufacturing steps, eliminating the need for skilled welders and expensive welding equipment, while maintaining design flexibility.
3Strength
If metal core with metal or plastic bristles is used, then brush strength is improved, but recyclability is reduced due to mixed materials
Solution Approach 1:
The core element and brush element strips are both formed from thermoplastic materials through injection molding. This homogeneous material composition throughout the brush structure enables efficient recycling. The uniform thermoplastic construction allows the entire brush to be melted and reformed, eliminating the complexity of separating and recycling mixed metal and plastic materials.
4Productivity
If extrusion process is used to produce brush cores, then production speed is improved, but the process is restricted to specific shapes and sizes for particular industries
Solution Approach 1:
The brush is segmented into a standardized core element with U-shape channels and interchangeable brush element strips. The core can be produced efficiently through injection molding in various configurations, while the brush element strips can be independently manufactured and then attached to create different brush types. This segmentation enables high productivity through standardized core production while maintaining versatility through interchangeable elements.
Solution Approach 2:
The standardized core element with its U-shape channel geometry serves as a universal platform that can accommodate multiple types of brush element strips. This universal core design allows a single core production process to support various brush configurations for different industries and applications, eliminating the need for separate extrusion processes for each brush type and thereby maintaining high productivity across all variations.

AI summary
A system and method that utilizes modular components to form a customizable brush for different applications with ease and at a low cost. The system and method utilizes three main components: a base, a plurality of rails, and a plurality of strip brush elements. The plurality of rails is fastened to the base and the plurality of rails holds the strip brush elements to the base to form a brush. All three components may be made of a thermoplastic or thermoset, non-metallic material which can be either rigid or flexible to allow the resulting brush to be easily recyclable.
