Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing connecting devices are used for warp yarn positioning elements, then connection can be achieved, but the devices are prone to damage and have shorter service life
Solution Approach 1:
The head is designed to change its radial dimension through elastic deformation, transitioning between a first radial dimension for passage through the female coupling part and a second radial dimension for detaining. This parameter change enables the connection mechanism to achieve reliable coupling while reducing susceptibility to damage during operation.
2Reliability
If complex connecting means are used for harness cords, then connection can be achieved, but the process becomes labor-intensive and reduces productivity
Solution Approach 1:
The elastic deformability of the head allows for simple axial movement during coupling and uncoupling operations. The head deforms radially to pass through the female coupling part's passage, then returns to its original shape to be detained, enabling quick and reliable connections without complex procedures or significant labor input.
3Reliability
If resilient clamping fingers are used to detain the head, then coupling can be achieved, but the clamping fingers are susceptible to damage and have greater impact on adjacent elements
Solution Approach 1:
Instead of using resilient clamping fingers that actively clamp onto the head, the invention inverts the approach by having the head itself deform and expand to be detained by the female coupling part's passage. The head's elastic deformation creates the coupling force, eliminating the need for separate clamping elements that could damage adjacent components.
4Adaptability or versatility
If harness replacement is performed using traditional methods, then harness cords can be replaced, but the task is labor-intensive and requires long down time
Solution Approach 1:
The elastically deformable head with its ability to change radial dimension enables rapid coupling and uncoupling of harness cords. The simple axial movement required for operation, combined with the elastic recovery of the head, allows for quick harness replacements with minimal loom downtime, making the process both adaptable and time-efficient.

AI summary
A coupling device for positioning elements for warp yarns, comprising a male coupling part (1) with a head (8) which, when elastically deformed, can be introduced into a female coupling part (11) via a passage (13) and assumes a larger transverse dimension beyond said passage, so that the head is detained there and the coupling parts (1), (11) are coupled. Beyond this passage (13), the female coupling part (11) comprises an axially displaceable uncoupling body (16) with an opening (17), so that the head can be introduced into this opening (17) and be deformed in the process to such an extent that it can be introduced into the passage (13) in order to uncouple the coupling parts.
