Modular Padded Arrow Head with Elastic Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for non-lethal arrow heads in recreational archery that are easy to manufacture, durable, and modular, allowing for individual component replacement to address wear and tear issues.
Innovation Solution
A padded head assembly comprising a foam tip, elastic attachment mechanism, and base, where the foam tip is secured to the base using elastic fingers, and the base is attached to the arrow shaft with a threaded fastener, allowing for modular replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a non-lethal arrow head is designed to be durable and easy to manufacture, then manufacturing cost and simplicity improve, but the ability to replace individual worn components is reduced
Solution Approach 1:
The arrow head is divided into three main segments: a base portion, a foam tip, and an elastic attachment mechanism. These segments are designed to be separable, allowing the foam tip to be replaced independently when worn, while the base and elastic mechanism can be reused. This segmentation enables easy repair without replacing the entire arrow head, resolving the contradiction between manufacturing simplicity and component replaceability.
2Duration of action of stationary object
If the arrow head design is made modular with replaceable components, then component lifespan is extended through replacement, but device complexity increases
Solution Approach 1:
The arrow head is segmented into a base, elastic attachment mechanism, and foam tip that can be assembled and disassembled. The elastic fingers provide a simple yet effective connection method that allows modular replacement of the foam tip while maintaining overall structural simplicity.
Solution Approach 2:
The foam tip is designed as a replaceable, relatively inexpensive component that can be replaced when worn, while the more durable base and elastic mechanism are retained. This approach extends the overall lifespan of the arrow head system by allowing replacement of only the worn component rather than the entire assembly.
3Ease of operation
If elastic fingers are used to attach the foam tip, then ease of assembly and disassembly improves, but attachment strength may be reduced compared to permanent bonding
Solution Approach 1:
The elastic fingers provide a dynamic attachment mechanism that allows for easy assembly and disassembly while maintaining sufficient holding strength during use. The elastic material provides both flexibility for easy manipulation during assembly and adequate strength to secure the foam tip during arrow flight and impact.

Function Achieved in This Case
The solution provides a durable, easy-to-manufacture, and modular non-lethal arrow head design that can be easily assembled and disassembled, extending the lifespan of the arrow head by allowing individual component replacement and improving the arrow's balance and safety features.
Implementation Method 1
The length of the finger or fingers may be elastically extended and wrapped around at least a portion of the foam tip, holding the foam tip against the flat support plate of the base
