Fastener Insertion Jaws for Single-Handed Delivery Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods of installing fasteners require manual handling, leading to potential dropping and increased risk of foreign object damage, and necessitate the use of both hands, limiting simultaneous performance of other tasks.
Innovation Solution
A fastener delivery system comprising a delivery device with an escapement mechanism and an insertion device featuring jaws and a track system, allowing single-handed operation and controlled fastener insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of fasteners is used, then the technician can easily grasp and insert fasteners, but the likelihood of dropping fasteners increases and both hands are occupied
Solution Approach 1:
The patent introduces a delivery device as an intermediary between the technician and the fasteners. The device includes a magazine that holds multiple fasteners and a delivery mechanism that presents one fastener at a time to the insertion point, eliminating the need for the technician to manually hold and transfer fasteners.
Solution Approach 2:
The delivery device is designed to automatically present fasteners for insertion without requiring manual handling. The mechanism includes features such as a spring-loaded ejector or gravity-fed system that automatically positions and presents fasteners, allowing the technician to simply guide the fastener into the workpiece.
2Reliability
If both hands are used for fastener insertion, then the technician can maintain control of fasteners, but the ability to perform simultaneous tasks is reduced
Solution Approach 1:
The delivery device serves as an intermediary that assumes the function of holding and presenting fasteners, freeing both of the technician's hands for other tasks such as positioning, alignment, or simultaneous fastener installation on multiple locations.
Solution Approach 2:
The system separates the fastener storage and presentation functions from the insertion function. The magazine and delivery mechanism handle fastener management, while the technician focuses solely on the insertion action, dividing the overall task into independent segments.
3Adaptability or versatility
If manual fastener handling is used, then the technician can adapt to different insertion positions, but the risk of foreign object damage increases
Solution Approach 1:
The delivery device acts as a controlled intermediary that manages fastener transfer in a controlled manner, reducing the chance of fasteners becoming loose or dropped compared to manual handling, while still allowing positioning flexibility.

AI summary
A system to deliver a fastener to a workpiece. The system includes a delivery device configured to hold the fastener. An insertion device receives the fastener from the delivery device. The insertion device includes jaws that are pivotally connected together and an insertion member engaged with the jaws with the insertion member movable relative to the jaws between a retracted position and an extended position. In the retracted position the insertion member positions the jaws at a closed position to prevent the fastener from being released from the jaws. In the extended position the insertion member positions the jaws in an open position to release the fastener from the jaws.
