Cradle Contact Member Segmentation for Yarn Winding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cradle designs for yarn winding machines require the entire bobbin holding section to be replaced when the contact member wears out, leading to high replacement costs and operational workload.
Innovation Solution
A cradle design where the base member and contact member are detachable, allowing only the contact member to be replaced by elastic deformation, reducing the workload and cost of maintenance, with a rotation preventing section using a protrusion and receiving section to prevent relative rotation between the contact and base members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base member and contact member are securely attached so as not to be detachable, then the structural integrity and reliability are improved, but the cost and work load in replacing the contact member increase
Solution Approach 1:
The bobbin holding section is segmented into a base member and a contact member that can be detached from each other. The contact member is designed as a separate replaceable component that can be detached by elastic deformation, allowing only the worn contact member to be replaced rather than the entire assembly, thus reducing replacement cost and workload while maintaining structural integrity during operation.
2Reliability
If the contact member is made from a material having a high friction coefficient to prevent slipping, then the reliability of yarn winding is improved, but the abrasion of the contact member increases
Solution Approach 1:
The contact member is designed as a consumable component that can be easily replaced through elastic deformation. When the contact member becomes worn from friction with the yarn, it can be quickly detached and replaced without replacing the entire bobbin holding section. This approach accepts the abrasion of the contact member in exchange for reduced overall replacement costs and maintained reliability.
3Ease of repair
If the contact member is made detachable by elastic deformation, then the ease of repair is improved, but the device complexity increases
Solution Approach 1:
The contact member utilizes its own elastic properties to enable self-detachment and self-mounting. The elastic deformation capability of the contact member itself serves as the detachment mechanism, eliminating the need for additional fasteners, clips, or complex release mechanisms. This self-service approach simplifies the overall structure while enabling easy replacement.

Function Achieved in This Case
This design reduces the workload and cost of replacing the contact member, ensuring accurate yarn winding by preventing slip and maintaining abrasion resistance, thereby improving the efficiency and quality of the yarn winding process.
Implementation Method 1
The contact member is detachably mounted to the base member by at least a portion of the contact member being elastically deformed

AI summary
A cradle includes a cradle main body, a larger-diameter side bobbin holding section, and a rotation preventing section. The larger-diameter side bobbin holding section is rotatably mounted on the cradle main body and adapted to hold a winding bobbin around which a yarn is wound. The larger-diameter side bobbin holding section includes a base member (70) and a contact member. The base member (70) is rotatably mounted on the cradle main body. The contact member is detachably mounted to the base member (70) by at least a portion of the contact member being elastically deformed, and adapted to hold the winding bobbin by making contact with the winding bobbin. The rotation preventing section is adapted to present relative rotation of the contact member with respect to the base member (70).
