Solution Overview

Problem

Conventional bowfishing arrows compromise arrow strength when attaching a retrieval line stop, leading to potential loss of the stop during use.

Innovation Solution

A bowfishing nock adapter with an elongated adapter body that securely attaches to the arrow using a crimpable arrow retention system, featuring a stop supporting element for the line stop and a nock receiving cavity, allowing for secure attachment without weakening the arrow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a hole is drilled into the arrow shaft to attach the stop, then the stop can be securely attached, but the arrow shaft strength is weakened

Engineering Contradiction:
Improvestop attachment securityVSAvoidarrow shaft strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The patent introduces an adapter as an intermediary component that attaches to the arrow shaft without requiring holes through the shaft itself. The adapter serves as a mediator between the arrow shaft and the stop, allowing the stop to be securely attached while preserving the integrity of the arrow shaft. The adapter can be attached using methods such as crimping, adhesives, or interference fits that do not compromise the shaft's structural strength.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of repair

If the stop is made removable for ease of replacement, then maintenance is easier, but the risk of accidental removal increases

Engineering Contradiction:
Improvestop replacement easeVSAvoidaccidental removal prevention
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The patent implements a dynamic attachment system where the stop can be easily removed and reattached through threaded connections or bayonet-style mounts. These mechanisms provide controlled removability - easy enough for intentional replacement by the user, but sufficiently secure to prevent accidental removal during normal use. The adapter body incorporates features like threaded holes or engagement detents that balance ease of maintenance with operational reliability.

AI summary

A bowfishing nock adapter providing a robust stop supporting element configured to support a bowfishing line stop and to support a nock is disclosed. The bowfishing nock adapter may be formed from an elongated adapter body configured to be attached to a distal end of an arrow at a proximal end of the elongated adapter body. The elongated adapter body may include an arrow retention system that, once crimped, prevents the bowfishing nock adapter from being removed from an arrow. The bowfishing nock adapter includes a stop supporting element configured to support a bowfishing line stop such that the bowfishing line stop is removable.
