Rotating Jaw Positioning Assembly for Fastener Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-driven fastener systems lack the accuracy required for precise placement of fasteners in workpieces, often relying on user alignment which can be inconsistent.
Innovation Solution
A positioning assembly with a driver guide tube and elongated driver shaft, featuring a first jaw fixed to the guide tube and a second jaw that rotates to form a guide channel with an arcuate cross-section, along with a locking member to ensure accurate fastener alignment and retention, enhancing the precision of fastener placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a positioning assembly with rotating jaw and guide channel is added, then manufacturing precision of fastener placement is improved, but device complexity increases
Solution Approach 1:
The positioning assembly is segmented into separate functional components: a guide tube for longitudinal positioning, a rotatable jaw assembly for lateral positioning, and a locking mechanism. This segmentation allows each component to perform its specific function independently while maintaining overall system precision without excessive complexity.
Solution Approach 2:
The jaw assembly is designed to be rotatable rather than fixed, allowing dynamic adjustment of the guide channel orientation. This dynamic feature enables precise fastener placement by aligning the guide channel with the drive shaft axis, while the rotation capability is controlled through a locking mechanism that maintains stability during operation.
2Reliability
If a locking member is added to retain the rotated jaw position, then reliability of fastener alignment is improved, but device complexity increases
Solution Approach 1:
The locking member is designed to automatically engage with the rotatable jaw assembly when the jaw is rotated to the correct position. The locking mechanism utilizes the jaw's own rotational movement to trigger the locking action, reducing the need for separate control systems and minimizing overall device complexity while maintaining reliability.
3Ease of operation
If the second jaw is made rotatable to form guide channel, then ease of operation for alignment is improved, but stability of the object's composition worsens
Solution Approach 1:
The second jaw is designed with rotational capability to allow easy alignment adjustment during setup or repositioning. However, once the desired alignment is achieved, the locking member engages to lock the jaw in its rotated position, providing stability during the fastener driving operation. This combination of dynamic adjustability and static locking resolves the contradiction between ease of operation and positional stability.

AI summary
A positioning assembly for a driving system, the assembly having a first jaw and a second jaw, the first jaw fixed to a driver guide tube, the second jaw fixed to the first jaw to allow one end of the first jaw to rotate away from the second jaw about a connection point, each jaw having an interior channel. The interior channel of the first jaw has an arcuate cross-section. The interior channel of the second jaw is formed from a plurality of walls including an arcuate upper wall and a sub-channel having cross-section formed by a base surface and two side walls, each side wall angled with respect to the base surface. The apparatus also includes a locking member configured to engage the second jaw when the second jaw is rotated away from the first jaw and retain the second jaw in a rotated position.
