Solution Overview

Problem

The handling of chain trees in chain activities is complex due to the integration of drive and storage functions, leading to increased setup times and costs, as well as maintenance challenges.

Innovation Solution

A separation of torque transfer and storage arrangements allows for a smaller, optimized design where the drive unit only serves the actual drive, enabling separate maintenance and automation of kett tree handling, with a movable fixation element and fixing mechanism for easy kett tree change and torque transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the drive unit and warehouse are integrated in a single block, then the storage function is combined with the drive function, but the complexity of changing the kett tree increases

Engineering Contradiction:
Improveintegration of drive and storage functionsVSAvoidcomplexity of changing the kett tree
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the previously integrated drive unit and warehouse into separate components. The drive unit remains on the cone while the warehouse is positioned separately, allowing independent access to each component. This segmentation enables the kett tree to be changed without requiring disassembly of the entire integrated block, thus reducing complexity while maintaining both drive and storage functions.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the kett tree is stored in a closed warehouse block, then the storage function is achieved, but the setup times increase

Engineering Contradiction:
Improvestorage functionVSAvoidsetup times
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The warehouse is designed with an openable door that can be dynamically adjusted between closed and open positions. During normal operation, the door remains closed to maintain storage function. During kett tree changes, the door can be quickly opened to allow rapid access and replacement of the kett tree, significantly reducing setup times while maintaining storage reliability during operation.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the drive unit serves both drive and storage functions, then the functionality is comprehensive, but the maintenance challenges increase

Engineering Contradiction:
Improvedrive and storage functionalityVSAvoidmaintenance challenges
Core Design Contradiction:
Adaptability or versatilityVSEase of repair

Solution Approach 1:

By separating the drive unit from the warehouse block, the patent enables independent maintenance of each component. The drive unit can be serviced without accessing the warehouse, and the warehouse can be maintained without disturbing the drive mechanism. This segmentation eliminates the need to disassemble an integrated block for routine maintenance, significantly improving ease of repair while preserving both drive and storage functionalities.

Inventive Principle:
Principle #1Segmentation

AI summary

A warp knitting machine has a warp beam (2) with a pivot (1), wherein the warp beam (2) is supported at the pivot (1) by a bearing arrangement located on the warp knitting machine, and the warp beam (2) is driven at the pivot (1) by a torque transmission arrangement. The aim is to handle the warp beam of a warp knitting machine economically. For this purpose, the torque transmission arrangement and the bearing arrangement are arranged separately from each other.
