Solution Overview
Problem
Existing shedding machines for weaving looms face issues with lubrication systems, including leaks, complex assembly, and maintenance difficulties due to the use of flexible hoses and limited adaptability, which affect the machine's reliability, compactness, and ease of maintenance.
Innovation Solution
A shedding machine with a lubrication system that integrates a pump directly connected to the frame, eliminating the need for flexible pipes, and featuring a trochoid-type pump with inversion means and a distribution system within the common shaft, along with a detection probe and filtering system, to ensure efficient lubricant circulation and distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flexible hoses are used to conduct lubricant to the shaft, then the lubrication system can be assembled, but the machine becomes complex and prone to leaks
Solution Approach 1:
The patent merges the lubrication system components by integrating the pump directly into the frame structure and combining rigid conduits with the frame, eliminating the need for separate flexible hoses. The pump body is mounted directly to the frame, and rigid conduits are integrated into the frame structure, creating a unified, leak-free lubrication system that reduces complexity while improving reliability.
2Ease of repair
If flexible hoses are used for lubricant distribution, then the system can be assembled, but maintenance operations become difficult
Solution Approach 1:
The patent combines the lubrication system with the frame structure using rigid conduits integrated into the frame, eliminating flexible hoses that complicate maintenance. The pump is directly mounted to the frame, and all lubrication components are positioned for easy access, making maintenance operations straightforward while reducing overall system complexity.
3Volume of moving object
If a pump with rigid conduits is used, then the machine becomes more compact, but adaptability to different loom configurations is reduced
Solution Approach 1:
The patent incorporates an inversion mechanism that allows the pump and associated components to be repositioned or reconfigured based on different loom requirements. The rigid conduits are designed to accommodate positional adjustments, and the pump mounting system allows for reconfiguration, maintaining compactness while providing adaptability to various loom configurations through controlled dynamic adjustment rather than fixed rigid installation.
4Reliability
If the pump is connected to the frame with rigid conduits, then leaks are reduced, but assembly complexity increases
Solution Approach 1:
The patent merges the pump mounting system with the frame structure, integrating the rigid conduits directly into the frame design. This combination eliminates the need for separate connection components and simplifies the assembly process, while the rigid conduit integration ensures leak-free operation. The unified design reduces the number of assembly steps and improves both manufacturability and reliability.
