Screw Magazine Collating Strip Feeding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in handling and driving screws individually during construction processes, such as decking, due to the cumbersome process of orienting and positioning each screw with a fastening tool, leads to a need for a system that can efficiently feed and align multiple screws for faster and more efficient driving.
Innovation Solution
A screw magazine system that includes a magazine body to hold a collated strip of screws, a pusher mechanism to advance screws towards a discharge end, and a bit opening for a drive bit, allowing for automated alignment and driving of screws, improving the speed and efficiency of screw placement and driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If screws are handled and driven individually, then precision in screw placement is maintained, but productivity and speed of construction are reduced
Solution Approach 1:
Screws are pre-oriented and pre-positioned in the magazine body before use. The magazine holds multiple screws in the correct orientation, so when a screw is dispensed, it is already ready to be driven without requiring the user to manually orient or position it, thus saving time while maintaining precision
Solution Approach 2:
The system separates the screw storage, orientation, and dispensing functions into a dedicated magazine device. This segmentation allows screws to be prepared in advance (pre-oriented in the magazine) while the user focuses on the driving action, improving overall productivity without sacrificing placement precision
2Productivity
If a magazine system is introduced to feed screws automatically, then productivity and speed are improved, but device complexity increases
Solution Approach 1:
The magazine body is designed to automatically dispense screws as they are driven. The pusher mechanism is spring-loaded and automatically advances the next screw into position after each drive cycle, eliminating the need for manual intervention or complex automated feeding systems, thus improving productivity while keeping the device relatively simple
Solution Approach 2:
The magazine body combines multiple functions: storing multiple screws, maintaining their orientation, and automatically feeding them to the drive bit. By merging these functions into a single integrated device, the system improves productivity without proportionally increasing complexity, as the same structure performs multiple tasks
3Ease of operation
If multiple screws are collated and stored together, then handling efficiency is improved, but the risk of injury from loose screws increases
Solution Approach 1:
Screws are pre-grouped and secured in the magazine body before use. By having screws pre-positioned and contained in the magazine rather than handled as loose items, the system improves handling efficiency while simultaneously reducing the risk of injury from loose screws
Solution Approach 2:
The magazine body acts as an intermediary between the bulk supply of screws and the individual screw being driven. It provides a safe, contained environment that holds multiple screws securely, allowing efficient access to individual screws while eliminating the hazards associated with handling loose screws directly

AI summary
A screw magazine having a loading end for receiving a collated strip of screws. The magazine includes a pusher that urges screws of a collated strip toward a discharge end of the magazine. A bit opening at a top and at the discharge end of the magazine is configured to receive a drive bit for driving the at least one screw through a discharge opening at a bottom of the magazine body. Also provided is a collated scrip of screws including a plurality of screws coupled to a rigid support configured to be held in a hand of a single user to allow driving of the screws with the other hand.
