Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Warp knitting machines face challenges in stabilizing knitting tools under high mechanical loads and production speeds, leading to potential deformation and increased machine weight due to the use of conventional knitting tool holders and fasteners.
Innovation Solution
A knitting tool with multiple interconnected elements and a connecting piece arranged above the lower sixth of each element, providing a wide footprint for secure insertion into grooves, which stabilizes the active elements and reduces material usage while allowing for quick assembly and minimizing weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If knitting tools are attached directly to the bar using conventional holders and fasteners, then the knitting tools can be secured in place, but the bar weight increases which negatively impacts machine dynamics
Solution Approach 1:
The patent combines multiple knitting tools into a single knitting tool unit with interconnected working elements. This merging eliminates the need for separate holders and fasteners for each tool, reducing the total number of components and overall bar weight while maintaining secure attachment through a unified connection system.
Solution Approach 2:
The connecting piece serves multiple functions: it connects adjacent working elements together, provides spacing between them, and enables the entire assembly to be secured to the bar as a single unit. This multi-functionality reduces the need for separate fastening components, lowering bar weight while ensuring reliable securing.
2Productivity
If knitting tools are subjected to high mechanical stress at high production speeds, then production output increases, but deformation of the working elements occurs
Solution Approach 1:
By combining multiple working elements into a single interconnected tool unit, the structure provides mutual support and stabilization. The interconnected design distributes mechanical stresses across multiple elements rather than concentrating them on individual tools, reducing deformation while maintaining high production speeds.
Solution Approach 2:
The patent employs a connecting piece that materially connects adjacent working elements, creating a composite structure. This composite construction enhances the overall rigidity and stress resistance of the knitting tool assembly, preventing deformation under high mechanical loads while enabling high-speed operation.
3Ease of repair
If knitting tools are replaced individually rather than in groups, then replacement flexibility increases, but the complexity of the attachment system increases
Solution Approach 1:
The patent merges multiple working elements into a single replaceable unit that can be attached to the bar as one assembly. This allows for individual tool replacement within the unit while maintaining a simplified attachment system, avoiding the need for complex separate fasteners for each tool.
4Productivity
If multiple working elements are interconnected in a single knitting tool, then fewer assembly steps are necessary and bar loading speed increases, but the width of the knitting tool increases requiring specially designed grooves
Solution Approach 1:
The patent arranges multiple working elements in a compact configuration within the groove, utilizing the vertical and depth dimensions rather than only horizontal spacing. This dimensional optimization allows multiple elements to be interconnected in a space-efficient manner, enabling faster bar loading while minimizing the required groove width.
