Integrated Weaving Machine Drive With Detachable Converter Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weaving machine drives require complex and costly assembly processes due to the need for long electrical connections between converters and electric motors, which increases material requirements and poses safety risks, especially when the electric motor is movably mounted.
Innovation Solution
A drive system featuring a brushless electric motor with a detachable converter housed in a metal enclosure, connected via a ground cable for safety and electromagnetic compatibility, allowing for a pre-assembled structural unit that simplifies installation and reduces manufacturing costs by eliminating the need for extensive cable adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the converter and electric motor are connected using long electrical cables in a common control cabinet, then installation and monitoring are simplified, but material requirements increase and safety hazards arise
Solution Approach 1:
The patent merges the converter and electric motor into a single integrated drive unit, eliminating the need for long electrical cables by directly connecting the converter to the motor. This integration reduces material requirements and safety hazards while maintaining ease of installation and monitoring through the unified structure.
Solution Approach 2:
The drive system is segmented into modular components (converter housing, motor housing, common support) that can be independently manufactured and then assembled together, allowing for simplified installation while reducing cable length through direct coupling of modules.
2Adaptability or versatility
If the electric motor is mounted on a movable support, then thread guidance flexibility is improved, but cable tolerance requirements increase
Solution Approach 1:
By integrating the converter and motor into a single movable unit, the patent eliminates cable flexibility issues entirely. The combined drive unit can move as one rigid structure, providing thread guidance flexibility without requiring complex cable tolerance designs.
3Ease of manufacture
If the converter and electric motor are integrated into a single drive unit, then assembly is simplified and manufacturing costs are reduced, but the converter housing must be detachably connected to the motor housing
Solution Approach 1:
The converter and motor are segmented into separate housings with standardized detachable connection interfaces, allowing for simplified manufacturing and assembly while enabling easy maintenance and replacement of individual components without affecting the entire drive unit.
