Bristle Bundle Production Device with Nested Filament Arrangement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing bristle bundles for brushes and brooms lack the flexibility to create complex and individualized designs, limiting the customization and uniqueness of bristle arrays, and do not provide adequate protection against imitation.
Innovation Solution
A method and device that combine at least one inner partial bundle of a first filament type with one or two outer partial bundles of a second filament type to form a bristle bundle, where the outer filaments surround the inner filaments in a defined relative arrangement, creating distinct zones within the bundle, and a device with discharge openings that ensure a high degree of enclosure to achieve a sharp separation of filament types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional methods combine bristle bundles without structured arrangement, then production is simpler, but design flexibility and individualization are limited
Solution Approach 1:
The bristle bundle is segmented into multiple partial bundles (first, second, third partial bundles) with different filament types arranged in specific spatial relationships. This segmentation enables complex design patterns while maintaining organized production through defined assembly structures.
Solution Approach 2:
Different regions of the bristle bundle have different filament types and properties - the first partial bundle has a different filament type than the second and third partial bundles. This local differentiation enables customized design patterns in different areas of the brush.
2Adaptability or versatility
If bristle bundles use mixed filament types without clear separation, then production is easier, but design complexity and protection against imitation are reduced
Solution Approach 1:
The bundle is divided into distinct partial bundles with clear spatial separation. The first partial bundle is positioned differently relative to the second and third partial bundles, creating visually distinguishable zones with different filament types that are precisely separated.
Solution Approach 2:
The arrangement of partial bundles within the main bundle is asymmetric - the first partial bundle has a different spatial relationship with the second and third partial bundles compared to their relationship with each other. This asymmetric arrangement creates unique design patterns that are difficult to replicate.
3Manufacturing precision
If outer partial bundles completely surround inner partial bundles, then filament separation is sharper, but device complexity increases
Solution Approach 1:
The partial bundles are arranged in a nested configuration where the first partial bundle is positioned within the spatial envelope formed by the second and third partial bundles. This nesting achieves sharp filament separation with a relatively simple feed element structure.
Solution Approach 2:
The partial bundles are arranged in three-dimensional space rather than simple linear or planar configurations. The first partial bundle is positioned at a different spatial level or angle relative to the second and third partial bundles, achieving sharp separation through spatial dimensionality.

AI summary
The invention relates to improvements in the technical field of brush manufacturing. Among other things, the device (1) for producing bristle bundles (2) is proposed. This device includes at least one feed element (3) which has at least one outer discharge opening (4) for dispensing at least one outer sub-bundle (5) and at least one inner discharge opening (6) for dispensing an inner sub-bundle (7) of a bristle bundle (2) to be produced. To achieve a sharp separation of the different bristle filaments introduced into the bristle bundle (2) by means of the at least two different sub-bundles (5, 7) in the finished bristle bundle (2), the at least one outer discharge opening (4) surrounds the at least one inner discharge opening (6) of the feed element (3) with a total circumferential coverage of at least 66 percent (see Fig. 1).
