Twisted Arrowhead Attachment for Expanded Cutting Diameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional arrowheads are costly and inefficient in bringing down large game animals, with a low recovery rate due to their limited effective cutting diameter and high cost of multiple-element devices.
Innovation Solution
A unitary arrowhead attachment made from a planar sheet of material, which can be twisted from a shipping configuration to an operable configuration, featuring an annular body and radial arms with piercing tips, expanding the cutting diameter for increased penetration and bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If conventional broad head arrows are used, then the arrow can penetrate the game animal, but the effective cutting diameter is limited and recovery rate is low
Solution Approach 1:
The arrowhead is divided into multiple radial arms (typically 3-6 arms) extending from a central annular body, with each arm equipped with piercing tips. This segmentation creates multiple cutting edges that expand the effective cutting diameter while maintaining structural integrity during flight, directly addressing the limited cutting diameter and low recovery rate problems of conventional single-blade arrowheads.
2Area of moving object
If multiple element devices are used to increase effectiveness, then the cutting diameter increases, but the cost increases significantly
Solution Approach 1:
The invention merges multiple functional elements (annular body, radial arms, piercing tips) into a single integrated arrowhead structure that can be manufactured as one piece using stamping or forming processes. This eliminates the need for assembling multiple separate components, significantly reducing manufacturing complexity and cost while maintaining the expanded cutting diameter achieved through the radial arm configuration.
Solution Approach 2:
The arrowhead utilizes a planar sheet material that is transformed through forming processes into a three-dimensional configuration with radial arms. This parameter change from two-dimensional sheet to three-dimensional formed structure enables the expanded cutting diameter without requiring multiple assembled parts, thereby reducing manufacturing cost while achieving the desired functional improvement.
3Ease of manufacture
If a unitary construction is used, then the manufacturing cost decreases, but the effective cutting diameter remains limited
Solution Approach 1:
The invention takes a planar two-dimensional sheet material and transforms it into a three-dimensional structure with radial arms extending outward from the annular body. This dimensional transformation allows the unitary construction to achieve a large effective cutting diameter that would be impossible with a simple flat blade, while still being manufactured as a single piece through forming processes.

AI summary
An arrowhead attachment is provided. The arrowhead attachment may be formed from a unitary sheet of attachment material so as to be bent and/or twisted from a shipping configuration to an operable configuration. The arrowhead attachment may include an annular body and a plurality of radial arms extending from a periphery of the annular body. In the shipping configuration, at least one piercing tip is disposed alone each radial arm so as to be co-planar with the plurality of radial arms and the annular body. A user may use a common tool to twist the arrowhead attachment from the shipping configuration to the operable configuration. Then the user may place the arrow shaft through a shaft opening formed by the annular body so as to couple the arrowhead attachment behind an arrowhead.
