Collated Fastener Positioner With Universal Screw Gun Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw driving systems are limited to specific screw sizes and require manual switching of receivers, making them incompatible across different screw guns and inefficient for driving multiple screw sizes.
Innovation Solution
A device comprising a positioner and coupler that can hold and advance a variety of fastener sizes, compatible with any screw gun, using a rocker and roller mechanism to sequentially position fasteners in front of the driver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a screw gun system uses a receiver configured to hold and advance a belt of screws of a specific size, then the system can efficiently drive screws of that specific size, but the system cannot accommodate different sized screws without removing and replacing the receiver
Solution Approach 1:
The receiver is designed with a universal interface that can accommodate multiple screw sizes through a single standardized configuration. The belt guide and advancement mechanism are configured to work with various screw diameters and lengths, allowing the same receiver to handle different screw types without modification or replacement.
Solution Approach 2:
The receiver incorporates adjustable components that can dynamically adapt to different screw sizes. The belt positioning and guide structures allow for flexible adjustment to accommodate varying screw dimensions, enabling the system to maintain efficient operation across different screw types through dynamic reconfiguration rather than static fixed-size design.
2Productivity
If a screw gun system is designed to work exclusively with specific screw sizes, then the system can be optimized for that specific application, but the system requires manual removal and attachment of different receivers when different sized screws are needed
Solution Approach 1:
The receiver design provides universal compatibility across screw sizes, eliminating the need for manual receiver switching. The standardized interface and adaptable internal mechanisms allow the same receiver to efficiently drive various screw types, maintaining high productivity while simplifying operation by removing the complexity of receiver replacement.
3Productivity
If a belt of screws is fed through a screw gun with manual or automatic advancement, then the system can position screws sequentially, but the system lacks compatibility across different screw gun models and requires system-specific belts
Solution Approach 1:
The screw feeding system is segmented into standardized, modular components including the belt structure, screw spacing, and interface mechanisms. This segmentation allows different screw guns to use compatible standardized belts while maintaining sequential positioning capability, enabling cross-system compatibility without sacrificing productivity.
Solution Approach 2:
The belt design incorporates universal features that enable compatibility across different screw gun models. The standardized screw spacing, belt dimensions, and interface configurations allow the same belt to work with multiple screw gun systems, maintaining efficient sequential positioning while achieving cross-system versatility.

AI summary
A device that positions a series of fasteners in front of a driver, includes a positioner and a coupler. The positioner is operable to locate a fastener in front of the driver, and includes a receiver, a rocker, and a roller. The receiver holds and guides a clip that holds a plurality of fasteners adjacent each other. The rocker moves the clip through the receiver such that each of the plurality of fasteners is sequentially positioned in front of a bit of the driver, ready to be driven into a material. The coupler is operable to couple the positioner with the driver, and includes a mount and a body. The mount is operable to releasably fasten the coupler with the driver. The body holds the positioner while the positioner moves relative to the body, and has a groove in which the roller travels as the positioner moves relative to the body.
