Grooved Washer Structure for Stable Screw Carrier Tape Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a mutual fixing structure between washers and screw carrier tapes leads to screws falling off during carrying, causing inconvenience and difficulty in handling multiple screws.
Innovation Solution
A grooved washer with a ring body and metal gasket design that includes an annular groove and perforation, which limits the carrier tape, ensuring the washer remains stable on the tape even when upside down, and a metal gasket for secure fastening and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smooth washer is used on the screw, then the washer can be easily mounted on the screw, but the washer may slide out from the positioning aperture on the carrier tape causing screws to scatter
Solution Approach 1:
The washer surface is designed with different local qualities: the mounting surface remains smooth for easy screw attachment, while the positioning surface features a groove structure that provides localized engagement with the carrier tape. This local quality differentiation resolves the contradiction by maintaining ease of mounting while preventing sliding out.
Solution Approach 2:
The solution transitions from a two-dimensional smooth surface to a three-dimensional groove structure on the washer positioning surface. The groove creates vertical engagement features that interact with the carrier tape positioning aperture, adding a dimensional element that prevents lateral sliding while maintaining the smooth mounting surface.
2Device complexity
If the washer has no fixing structure with the carrier tape, then the mounting process is simple, but the screw may drop from the carrier tape causing inconvenience
Solution Approach 1:
The washer incorporates a groove structure at the specific location where it contacts the carrier tape positioning aperture. This localized structural modification provides the necessary fixing function without requiring complex overall redesign of the washer or mounting system, thus maintaining simplicity while preventing screw dropout.
Solution Approach 2:
The groove structure acts as an intermediary mechanism between the washer and the carrier tape positioning aperture. It creates a mechanical interlock that prevents the screw from dropping, serving as a mediating structure that connects the washer to the carrier tape without requiring complex fastening systems.

AI summary
A grooved washer is used on a screw carrier tape and has a ring body. The ring body has an outer side face, a groove, two groove walls, and a perforation. The groove is annularly formed in the outer side face. The two groove walls are oppositely defined in the groove. The perforation is formed through a center of the ring body and through the top surface of the ring body and the bottom surface of the ring body. Moreover, the grooved washer has a metal gasket which is attached to the top surface of the ring body. With the groove, the grooved washer limits the carrier tape to be stuck on the screw carrier tape so that screws are stably located in the positioning apertures without falling from the screw carrier tape and being scattered, so as to improve the convenience in use.
