Modular Broadhead Interchangeable Base Tip Weight

Solution Overview

Problem

Archers face challenges in easily switching between different types of broadheads and adjusting the weight of arrow tips for various hunting and target shooting applications, as existing solutions do not provide a convenient method for changing tip types or weights without altering the entire arrow setup.

Innovation Solution

The development of modular broadheads with interchangeable bases and tip portions that can be mixed and matched to adjust the weight and type of broadheads, allowing archers to conveniently switch between field points, fixed blade broadheads, and mechanical broadheads by threadably mounting different bases and tip portions to an arrow shaft.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If archers use traditional fixed broadheads or field points, then the arrow configuration is simple and stable, but the archer cannot easily switch between different broadhead types or adjust weights

Engineering Contradiction:

Improveability to switch broadhead typesVSAvoidcomplexity of arrow setup

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The broadhead system is divided into separate modular components: a base portion that attaches to the arrow shaft and interchangeable tip portions that can be screwed onto the base. This segmentation allows archers to swap between different tip types (field points, fixed blade broadheads, mechanical broadheads) without replacing the entire broadhead assembly, thereby improving adaptability while maintaining relatively simple device complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base portion is designed as a universal mounting platform that can accommodate multiple types of tip portions through standardized threading. This multi-functionality enables a single base to support various broadhead configurations and weight combinations, allowing archers to switch between different hunting and target shooting applications using one base unit

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If archers want to adjust the weight at the front of the arrow, then they need to change the entire arrow setup, but this is time-consuming and inconvenient

Engineering Contradiction:

Improveability to adjust arrow weightVSAvoidtime to change arrow configuration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

AI summary

Modular broadheads for use with an archery bow and arrow include interchangeable bases and tip portions which can be mixed and matched in various permutations as selected by an archer. An archer may conveniently switch between different types of broadheads on an arrow such as field points for target shooting, fixed blade broadheads for hunting, and/or mechanical blade broadheads for hunting without changing the broadhead weight. Alternately, an archer may conveniently change the weight at the front of the arrow by changing one or both of the base and tip portions.
