A pre-holding clip with a cylindrical tubular body, external spring elements, and internal protrusions that secure to a screw by screwing, allowing it to be held in a spacer and maintained in position until the screwing station, facilitating easy installation and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a staple is used to hold the screw in the spacer, then the screw can be pre-held in position, but the mounting and dismounting operations become complex
Solution Approach 1:
The spring element provides dynamic elasticity, allowing the clip to automatically adapt to the screw diameter and mounting conditions. The elastic deformation of the spring element enables simple insertion and removal operations while maintaining reliable screw holding during assembly line advancement.
2Adaptability or versatility
If the spring element is very elastic to accommodate diameter variations, then adaptability improves, but the clip may become detached during assembly line advancement
Solution Approach 1:
The spring element's elasticity parameter is optimized to provide sufficient adaptability for diameter variations while maintaining adequate retention force. The geometric parameters of the spring element (wire diameter, coil diameter, pitch) are specifically designed to balance flexibility and retention reliability.
3Reliability
If the spring element is made very rigid to prevent detachment, then retention reliability improves, but the clip cannot accommodate diameter variations and mounting becomes difficult
Solution Approach 1:
The spring element provides dynamic elasticity, allowing the clip to automatically adapt to the screw diameter and mounting conditions. The elastic deformation of the spring element enables simple insertion and removal operations while maintaining reliable screw holding during assembly line advancement.
4Ease of operation
If the spring element has high elasticity for easy mounting, then ease of operation improves, but excessive torque may cause automaton faults
Solution Approach 1:
The spring element's elasticity parameter is optimized to provide sufficient adaptability for diameter variations while maintaining adequate retention force. The geometric parameters of the spring element (wire diameter, coil diameter, pitch) are specifically designed to balance flexibility and retention reliability.

AI summary
A pre-holding clip which is in the form of a sleeve, including a substantially cylindrical tubular body having an opening along its axis. The clip includes at least one spring element over the external surface of the body, the spring element projecting out of the external surface of the body and being able to be deformed towards the axis of the body; and the clip further includes at least one protrusion over the internal surface of the body, the at least one protrusion could be threaded when a tapped rod with an external diameter of the tapping larger than the internal diameter of the opening is introduced by screwing into the opening.
