Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a non-lethal arrow suitable for recreational activities similar to paintball, which can safely engage participants without causing injury.
Innovation Solution
A non-lethal arrow design featuring a shaft with a nock, fletching, and a tip connector with a foam tip that includes securing ribs and fins, providing a durable yet soft impact surface to prevent injuries, and allowing for easy replacement of the foam tip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional arrow with a hard tip is used, then the arrow can penetrate targets effectively, but it causes injury to participants in recreational activities
Solution Approach 1:
The tip of the arrow is changed from a hard, sharp material to a soft, compressible foam material. This parameter change in material hardness and compressibility allows the arrow to maintain its structural integrity and flight performance while significantly reducing the harmful impact force upon contact with participants, thereby preventing injuries in recreational activities
Solution Approach 2:
The foam tip is designed to compress and deform upon impact, converting the kinetic energy of the moving arrow into deformation energy rather than concentrated impact force. This transforms the potentially harmful sharp penetration into a safe, distributed cushioned impact that still provides sufficient tactile feedback for the game
2Object-affected harmful factors
If a foam tip is added to the arrow, then the arrow becomes non-lethal and safe for recreation, but the complexity of the arrow structure increases
Solution Approach 1:
The arrow is divided into distinct functional segments: the shaft, the fletching, the nock, and the removable foam tip. This segmentation allows each component to be optimized independently and enables the foam tip to be easily attached or removed as needed, adding safety functionality without permanently complicating the overall arrow structure
Solution Approach 2:
The foam tip is designed as a removable component that can be dynamically attached or detached from the shaft based on the intended use. This dynamic configuration allows the arrow to transition between lethal and non-lethal modes, providing safety when needed while maintaining simplicity for traditional use
3Object-affected harmful factors
If a foam tip is made soft and compressible, then it prevents injuries upon impact, but it may reduce the effectiveness of the arrow in reaching the target
Solution Approach 1:
Only the tip portion of the arrow is made soft and compressible using foam material, while the shaft and other flight-critical components maintain their traditional hard, aerodynamic design. This localized application of soft material ensures injury prevention at the point of contact without compromising the overall flight performance, speed, and stability of the arrow

AI summary
A non-lethal arrow is disclosed that includes a shaft extending along a longitudinal axis. A nock is located on a first end of the shaft and a flight is positioned at approximately the first end of the shaft. A tip connector is included that has a foam tip connection end and a shaft connection end. The shaft connection end is connected with a second end of the shaft. The foam tip connection end includes a plurality of securing ribs extending circumferentially about the foam tip connection end. The securing ribs taper upwardly toward a back surface thereby allowing the securing ribs to grip a foam tip connected with the foam tip connection end. The shaft connection end includes an elongate cylindrical portion defining a hollow tube that is sized and configured to receive the second end of the shaft.
