Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circular combs for combing machines face challenges in achieving precise and uniform positioning of tooth tips relative to the nipper unit, often resulting in radial end position variations and complex mounting processes.
Innovation Solution
A segmented circular comb base body with tangentially connected base body segments, each carrying a comb bar, is designed to apply a tangential tensile force during mounting, ensuring precise radial positioning and easy assembly, while allowing for individual adjustment of combing radius and flexibility in comb bar replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a radially height-adjustable mounting of a circular comb body is used, then the radial distance of tooth tips can be adjusted, but the circular comb may undergo concave bending causing position changes of tooth tips
Solution Approach 1:
The circular comb base body is divided into multiple base body segments that are tangentially connected. Each segment can be independently adjusted radially without causing bending of the entire comb body, as the segmented structure allows localized adjustment while maintaining overall circular integrity.
2Manufacturing precision
If complex mounting mechanisms are used to achieve precise positioning of tooth tips, then positioning accuracy improves, but assembly complexity increases
Solution Approach 1:
The base body is segmented into multiple independent segments that can be assembled tangentially. This segmentation simplifies the mounting process by allowing each segment to be positioned and secured independently, reducing the complexity of the overall mounting mechanism while maintaining precise positioning capability.
Solution Approach 2:
The base body segments are designed with pre-formed tangential connection features that enable straightforward assembly. The segments can be pre-positioned and connected tangentially before final securing, simplifying the mounting process and reducing assembly complexity.
3Strength
If the circular comb base body is made as a single piece, then structural integrity is maintained, but manufacturing accuracy and assembly ease deteriorate
Solution Approach 1:
The base body is divided into multiple segments that are tangentially connected, allowing each segment to be manufactured with high precision independently. The tangential connection maintains structural integrity while enabling better manufacturing accuracy compared to a single large piece.
Solution Approach 2:
Multiple base body segments are combined through tangential connection to form the complete circular comb base body. This merging approach maintains structural integrity similar to a single-piece construction while benefiting from the manufacturing and assembly advantages of segmentation.
4Adaptability or versatility
If adjustable mounting is used to position tooth tips, then radial distance can be modified, but the mounting process becomes more complex
Solution Approach 1:
The segmented base body structure allows individual segments to be adjusted radially independently. This segmentation enables radial distance adjustment without requiring complex overall mounting mechanisms, as each segment can be positioned and secured separately.
