Solution Overview
Problem
Existing fastening element driving apparatuses require time to load multiple fastening elements, and there is a need for an efficient mechanism to drive multiple fastening elements into a substrate quickly and accurately.
Innovation Solution
The apparatus features a setting channel with an energy transmitting element and a magazine that transports multiple rows of fastening elements alternately into the channel, utilizing angled insertion bevels and a feed element with offset contact surfaces to align and position fastening elements for efficient driving, along with a contact pressure element to ensure proper alignment and force transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple fastening elements are loaded into the magazine at one time, then productivity is improved, but device complexity increases
Solution Approach 1:
The magazine is divided into multiple rows (first row, second row, etc.) with separate receptacles for different fastening elements. Each row can be independently fed into the setting channel, allowing parallel loading of multiple fastening elements without requiring a completely complex reloading mechanism.
Solution Approach 2:
The magazine transports not only multiple fastening elements along the transport direction but also multiple rows arranged in the transverse direction. This multi-dimensional arrangement allows simultaneous access to multiple fastening elements, improving loading speed while maintaining manageable structural complexity.
2Productivity
If fastening elements are transported from multiple rows alternately, then productivity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The magazine is designed with movable components that can dynamically switch between transporting fastening elements from the first row and the second row. This dynamic alternation allows the system to maintain high productivity while managing alignment precision through controlled movement rather than requiring all elements to be perfectly aligned simultaneously.
Solution Approach 2:
The setting channel acts as an intermediary that receives and positions fastening elements alternately from different rows. This intermediary structure provides a controlled environment for precise positioning, allowing the magazine to transport elements from multiple rows without requiring the entire system to maintain high precision simultaneously.
3Manufacturing precision
If insertion bevels are used to guide fastening elements, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
Insertion bevels with angled surfaces are provided in the setting channel to guide fastening elements into proper alignment. These beveled surfaces provide a smooth, curved transition that automatically aligns fastening elements from different rows as they enter the setting channel, improving alignment precision without requiring complex mechanical alignment mechanisms.

AI summary
A device for driving fastening elements into a substrate comprises a setting channel; an energy transmission element, which can be moved in a fastening direction in the setting channel, for transmitting energy to one of the fastening elements at a time; and a magazine for transporting the fastening elements to the setting channel in a transport direction. The magazine is suitable for transporting multiple rows of fastening elements at once. Additionally, a fastening element strip comprises a plurality of rows of receptacles for fastening elements aligned in a transport direction and fastening elements which are housed in the receptacles and define a fastening direction, wherein the rows of receptacles are arranged one behind the other in a transverse direction oriented perpendicular to the transport direction and perpendicular to the fastening direction.
