Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carding wires face challenges in achieving a high carding effect with low wear and providing a large receiving space for fibers while maintaining stability.
Innovation Solution
A carding wire design with a foot section, leaf section, and blade section, featuring multiple tooth tips pointing in the same direction, optimized tooth spacing, and angled tooth faces to enhance fiber retention and carding performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple tooth tips are arranged on a common tooth body pointing in different directions, then the carding effect is improved, but the wear increases
Solution Approach 1:
The tooth body is segmented into multiple tooth tips (first tooth tip and second tooth tip) that are spatially separated and point in different directions. This segmentation allows each tip to perform carding functions independently, enhancing the overall carding effect while distributing wear across multiple contact points rather than concentrating it on a single tip.
Solution Approach 2:
The patent introduces a vertical dimension to the tooth arrangement by positioning the second tooth tip below the first tooth tip in the vertical direction. This three-dimensional configuration allows tooth tips to engage fibers from different depths and angles, improving carding effectiveness while reducing wear through varied contact geometries.
2Quantity of substance
If the tooth depth is increased to provide larger receiving space for fibers, then the fiber retention is improved, but the stability of the tooth body decreases
Solution Approach 1:
The tooth body is divided into multiple segments with different tooth tips at varying depths. The first tooth tip extends to a greater depth to provide large receiving space for fiber retention, while the second tooth tip is positioned lower to provide structural support and counterbalance, maintaining overall tooth body stability despite the deep first tooth tip.
Solution Approach 2:
The tooth body exhibits asymmetric geometry with the first tooth tip extending deeper than the second tooth tip. This asymmetric design optimizes fiber reception at the deeper first tip while the shorter second tip provides structural reinforcement, creating a balanced configuration that achieves both large receiving space and maintained stability.
3Ease of manufacture
If the tooth tips are arranged at uniform distance, then the manufacturing is simplified, but the carding effect is reduced
Solution Approach 1:
The tooth body is segmented into multiple tooth tips with different vertical positions (first tooth tip and second tooth tip at different heights). This segmentation allows the horizontal spacing to remain uniform for manufacturing simplicity, while the vertical separation creates varied engagement angles and depths, enhancing the carding effect through multi-level fiber interaction.

AI summary
A wire assembly (1) according to the invention has a base section (2) and a blade section (5). The blade height (6) is greater than the base height (4). The blade section has a plurality of identical tooth bodies (7). A tooth body extends longitudinally between two first recesses (8) of the blade section, which extend vertically as far as possible towards the base section. The tooth bodies are spaced apart longitudinally at a pitch (9). A first tooth tip (10) and at least one second tooth tip (11) are arranged on each tooth body. The first tooth tip adjoins a first recess (8) and points towards this first recess. The wire assembly is characterized in that the first tooth tip (10) and the second tooth tip (11), which is furthest away from the first tooth tip, are arranged on each tooth body at a tooth tip spacing (12) that is less than 50% of the pitch (9).
