Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bristle processing devices fail to mechanically sharpen bristles to a high quality with small cone angles, resulting in environmental concerns from chemical sharpening methods.
Innovation Solution
A bristle processing device with multiple intermediate magazines and a receiving unit, where bristle tufts are moved relative to a grinding device for simultaneous processing from multiple sides, creating a tapered end, and featuring a drive system for precise movement and handling of intermediate magazines and grinding units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If chemical sharpening method is used, then high quality tapered bristles with small cone angles can be produced, but environmental impact increases
Solution Approach 1:
The patent replaces the chemical sharpening system with a mechanical grinding system. A grinding device with a rotating grinding disc equipped with grinding grains mechanically abrades the bristle ends to create tapered shapes, eliminating the need for chemical agents and their associated environmental harm while achieving the desired bristle taper quality
Solution Approach 2:
The patent changes the physical state and parameters of the grinding disc, including its rotation speed, grinding grain distribution, and disc geometry, to optimize the mechanical grinding process. By adjusting these parameters, the system achieves high-quality tapered bristle ends with small cone angles through controlled mechanical action rather than chemical treatment
2Productivity
If multiple intermediate magazines are used for simultaneous processing, then productivity increases, but device complexity increases
Solution Approach 1:
The patent divides the bristle processing system into multiple independent intermediate magazines, each capable of holding and presenting bristle tufts to the grinding device. This segmentation allows simultaneous processing of multiple bristle batches, increasing productivity while maintaining manageable complexity through modular design
Solution Approach 2:
The intermediate magazines are designed as universal components that can be loaded, unloaded, and repositioned systematically. Each magazine serves multiple functions: storing bristle tufts, presenting them to the grinder, and receiving processed bristles. This multi-functionality reduces overall system complexity despite having multiple magazines
3Manufacturing precision
If bristles are ground from all sides simultaneously, then manufacturing precision of conical shape improves, but device complexity increases
Solution Approach 1:
The patent employs dynamic movement of the intermediate magazines relative to the stationary grinding disc. The magazines are positioned and moved to present bristle tufts at optimal angles to the grinding surface, enabling multi-sided grinding through systematic repositioning rather than complex multi-axis grinding mechanisms
Solution Approach 2:
The intermediate magazines act as intermediaries between the bristle supply and the grinding disc. They facilitate the presentation of bristles from multiple sides by rotating or repositioning the tufts before contact with the grinder, achieving conical shape precision without requiring the grinding device itself to have complex multi-directional capabilities

AI summary
The invention relates to a processing device for grinding the ends of bristles, comprising a bristle cartridge (12) in which bristles are arranged so as to stand next to one another and comprising multiple intermediate cartridges (16) equipped with recesses into which bristle bunches from the bristle cartridge (12) are inserted and thus individualized. The ends of the bristle bunches protrude axially relative to the respective paired intermediate cartridge (16). A receiving unit (14) to which multiple intermediate cartridges (16) are attached simultaneously is designed such that the intermediate cartridges (16) are moved during the grinding process. A grinding device then grinds the ends of the bristle bunches in the intermediate cartridges (16). At least one drive (52) is provided for the intermediate cartridges (16) and/or the receiving unit (14) so that the bristle bunches are moved by said drive (52) during the grinding process.
