Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular combs for combing machines face complexity in exchanging and accurately positioning individual comb segments due to complex production processes and insufficient accuracy, leading to inefficient and costly maintenance.
Innovation Solution
The use of flat permanent magnets to non-positively fasten clothing elements with toothed segments to the base body, allowing for secure and precise attachment without screw connections, and incorporating a form-fitting mechanism to prevent displacement and peeling effects, along with a depression for easy release, enables quick and accurate replacement of comb segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual comb segments are attached to the base body by means of screws or tongue/groove system, then the comb segments can be securely fastened, but the exchange and positioning of comb segments becomes complex and time-consuming
Solution Approach 1:
The patent replaces the traditional mechanical fastening systems (screws, tongue/groove connections) with a magnetic field-based fastening system. Flat magnets are arranged on the base body to create magnetic attraction zones that securely hold the comb segments without requiring mechanical fasteners, thereby simplifying the exchange and positioning processes while maintaining secure attachment.
Solution Approach 2:
The patent changes the fundamental attachment parameter from mechanical interlocking to magnetic attraction. By utilizing magnetic field strength as the attachment mechanism, the system achieves both secure fastening and ease of exchange, as the magnetic force can be easily overcome by simple pulling motions without requiring tools or complex disassembly procedures.
2Ease of operation
If individual comb segments are non-positively connected to the base body, then the replacement of comb segments is simplified, but the positioning accuracy of comb segments on the base body is insufficient
Solution Approach 1:
The patent introduces magnetic fields as an intermediary force between the base body and comb segments. The flat magnets arranged on the base body create localized magnetic attraction zones that guide and hold the comb segments in precise positions during replacement, ensuring both ease of operation and high positioning accuracy without requiring positive mechanical connections.
3Device complexity
If a single rod magnet is used to attach the comb segment to the base body, then the structure is simple, but the holding force is insufficient and the attachment is only secure in one area
Solution Approach 1:
The patent divides the single rod magnet into multiple flat magnets arranged on the base body. Each flat magnet creates a localized magnetic field that contributes to the overall holding force. This segmentation of the magnetic attachment system distributes the holding force across multiple contact points, significantly increasing the total holding force while maintaining structural simplicity.
Solution Approach 2:
The patent transitions from a one-dimensional rod magnet to a two-dimensional arrangement of flat magnets on the base body surface. This dimensional change allows the magnetic field to be distributed across a larger area, creating multiple attachment points that collectively provide superior holding force and more stable attachment across the entire comb segment surface.
