Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile machine tools housed in modules experience significant heat generation due to friction, leading to longitudinal expansion of the bar, increased dynamic loads, and bending loads, which are detrimental to machine operation, especially at higher working speeds.
Innovation Solution
A tool module with a module body featuring a contact surface and alignment structures for positioning, including additional openings that reduce weight, heat transfer, and enhance cooling through increased convection, thereby minimizing heat input into the bar and maintaining positioning accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the module body has a large contact surface with the bar, then positioning stability is improved, but heat transfer from the module to the bar increases, causing bar elongation
Solution Approach 1:
The contact surface is segmented into multiple discrete contact points or small areas rather than a large continuous surface. This segmentation maintains positioning stability through distributed contact while significantly reducing the total heat transfer area from the module body to the bar, preventing bar elongation.
2Temperature
If additional openings are made in the module body, then heat dissipation and weight reduction are improved, but structural strength is reduced
Solution Approach 1:
The module body exhibits local quality variations with different densities and structures in different regions. Areas requiring strength (near mounting openings and tool mounting zones) maintain solid construction, while areas requiring heat dissipation feature additional openings or porous structures. This localized differentiation optimizes both structural strength and thermal management.
3Productivity
If the working speed of the textile machine is increased, then productivity is improved, but dynamic loads and bending stresses on the bar increase
Solution Approach 1:
The module body incorporates counterbalancing features such as strategically placed openings, recesses, or mass distribution patterns that reduce the effective dynamic load on the bar during high-speed operation. These features create counteracting forces or reduce the moment of inertia, allowing the system to operate at higher speeds with reduced bending stresses on the bar.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for increased working speed of textile machines by reducing heat transfer and dynamic loads, improving positioning accuracy, and enhancing heat dissipation, thus preventing bar elongation and maintaining machine efficiency.
Implementation Method 1
The at least one opening can promote cooling of the module during machine operation. The heat generated by friction of the tools against a backing or other textile or thread is absorbed by the module body and released to the environment and, in a reduced manner, to the machine bar. Ideally, the heat is dissipated into the surrounding air. The oscillating operation of a bar with the tools attached to it forces convection. The at least one opening separate from the mounting opening creates additional turbulence in the air in contact with the module during machine operation, leading to increased convection and thus increased heat dissipation.
Implementation Method 2
A large portion of the drive power applied to the tools of a textile machine is converted into heat through friction, generating a relatively large amount of heat within the tools themselves. The heat generated by friction of the tools against a backing or other textile or thread is absorbed by the module body and released to the environment and, in a reduced manner, to the machine bar.
Implementation Method 3
The heat generated by friction of the tools against a backing or other textile or thread is absorbed by the module body and released to the environment and, in a reduced manner, to the machine bar.

AI summary
The invention relates to a tool module (10) having a module body (11), which has a contact surface (21) and an orienting structure (22). A fastening opening (29) and additionally at least one, preferably a plurality of additional openings (33, 34) extend through the contact surface (21). The area of one additional opening (33) or (34) is larger than, preferably considerably larger than, for example at least twice or three times as large as the cross-sectional area of the fastening opening (29). Thus, a module body (11) is provided, by means of which an increased operating speed of the textile machine can be achieved.
