Arrow Outsert with Axial Slots for Easy Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing arrow outserts with central sections of decreased diameter complicate the removal of arrows from penetrated objects, posing a challenge for easy extraction.
Innovation Solution
An arrow outsert with an elongated body featuring a tapered outer surface, axial slots, and a female thread to securely engage the arrow point and shaft, allowing for easy removal by reducing the central diameter and facilitating disengagement from penetrated objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an arrow outsert includes a central section with decreased diameter, then the structural integrity and engagement with arrow components is improved, but the ease of removal from penetrated objects deteriorates
Solution Approach 1:
The outsert is divided into multiple longitudinal segments that can separate from each other during removal. The axial slots extend partially through the outsert body, creating segmented sections that can flex and separate, allowing the outsert to be easily pulled from penetrated objects without requiring deformation or breaking of a central section.
Solution Approach 2:
The outsert features localized gripping elements (such as knurled surfaces, ridges, or textured areas) at specific positions to provide enhanced grip for removal tools. This allows the removal function to be concentrated at specific locations rather than requiring the entire central section to have special properties, maintaining structural integrity while facilitating easy removal.
2Reliability
If an arrow outsert includes a central section with decreased diameter, then the engagement with arrow shaft and point is improved, but the device complexity increases
Solution Approach 1:
The outsert design integrates multiple functions into a single component: it provides structural support, engages with both the arrow shaft and point, and facilitates easy removal through its segmented structure. The axial slots serve dual purposes of reducing material while maintaining strength and enabling the segmentation mechanism for easy removal, eliminating the need for separate removal tools or mechanisms.
Solution Approach 2:
Instead of using a decreased diameter central section to achieve engagement, the invention inverts the approach by using a uniform or increased diameter structure with axial slots that create effective engagement surfaces. The slots themselves create the necessary grip points and structural characteristics without requiring a reduced diameter section, simplifying the overall geometry while maintaining engagement reliability.

AI summary
An arrow outsert preferably includes a first end and a second end. An arrow point bore is formed in the first end of the arrow outsert to receive a cylindrical portion of an arrow point. An arrow shaft bore is formed in the second end of the arrow outsert to receive an arrow shaft. An outer surface of the arrow outsert is preferably tapered starting at the second end. A female thread is formed through a middle of the arrow outsert to threadably engage a threaded stud of the arrow point. A plurality of axial slots are formed in an outer perimeter of the arrow outsert. The arrow outsert is secured to an end of an arrow shaft by applying glue, adhesive or the like, before insertion into the arrow shaft bore. The threaded stud of the arrow point is threaded into the female thread to complete assembly.
