Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing warp yarn positioning systems on weaving looms face inefficiencies in connecting Jacquard lifting cords with harness cords, leading to time-consuming operations and productivity losses, particularly when different sets of coupling parts are incompatible, requiring costly and time-consuming replacements.
Innovation Solution
A set of coupling parts with first and second connection means that are not interconnectable, along with an adaptor featuring third and fourth connection means, allowing for a detachable and reliable connection using an elastically deformable coupling portion and receiving portion, enabling quick and easy installation and disconnection without tools, and accommodating different sets of coupling parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different sets of coupling parts are used to connect Jacquard lifting cords with harness cords, then connection reliability is improved, but compatibility is worsened requiring costly and time-consuming replacements
Solution Approach 1:
The adaptor is designed with dual functionality: it can connect to both first coupling parts (via third connection means) and second coupling parts (via fourth connection means), serving as a universal interface that eliminates the need for multiple specialized coupling parts and enables compatibility between previously incompatible systems
Solution Approach 2:
The adaptor acts as an intermediary component between incompatible coupling systems. By introducing this intermediate element with different connection interfaces on each end, it mediates the connection between first and second coupling parts that would otherwise be incompatible, allowing them to work together without replacement
2Reliability
If traditional connecting means are used for coupling cords, then connection reliability is maintained, but operation time is increased leading to productivity losses
Solution Approach 1:
The connection means are designed with self-aligning and self-latching features that enable automatic engagement when coupling parts are brought together. The elastically deformable coupling portion automatically deforms to pass through the receiving portion and locks into place, eliminating the need for manual alignment or additional fastening operations
Solution Approach 2:
The elastically deformable coupling portion utilizes elastic deformation as a key parameter change during connection. By temporarily deforming the coupling portion to a smaller size during insertion and then allowing it to return to its original larger size, the system achieves automatic locking without requiring time-consuming manual operations
3Ease of operation
If coupling parts are designed for easy detachment, then operation ease is improved, but connection strength may be compromised
Solution Approach 1:
The connection system transitions from a static locked state to a dynamic release state through rotational movement. The coupling portion can rotate within the receiving portion to engage or disengage locking features, providing both strong connection during operation and easy detachment when needed, with the strength dynamically adjusted through the rotation action
