Solution Overview

Problem

Existing crossbow quivers are bulky, obstruct the archer's line of vision, and inadequately address the covering of arrowheads, limiting their ease of use and storage capacity.

Innovation Solution

A quiver apparatus with an arrowhead bracket, hoods, and braces that allow for lateral interchangeability and secure storage of multiple arrows, featuring a magnetically attaching mechanism and removable hoods to cover arrowheads, enhancing usability and visibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a traditional quiver is used to store arrows, then arrow storage capacity is improved, but the device becomes bulky and obstructs the archer's line of vision

Engineering Contradiction:
Improvearrow storage capacityVSAvoidquiver bulkiness
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The quiver is divided into multiple arms (first arm, second arm, third arm) that can be independently positioned and folded. Each arm holds one or more arrows, allowing the quiver to store multiple arrows while minimizing overall volume when not in use by folding arms against the stock.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The quiver arms are designed to be movable and adjustable rather than fixed. The arms can be positioned at different angles and folded against the stock when not needed, transforming the quiver from a bulky static structure to a compact dynamic one that adapts to storage needs.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If a traditional quiver is used to store arrows, then arrow storage capacity is improved, but the quiver obstructs the archer's line of vision

Engineering Contradiction:
Improvearrow storage capacityVSAvoidarcher's line of vision
Core Design Contradiction:
Quantity of substanceVSIllumination intensity

Solution Approach 1:

The quiver arms can be folded against the stock when not in use, clearing the archer's field of view. When arrows need to be accessed, the arms can be quickly positioned or removed, minimizing obstruction during the critical shooting moment while maintaining storage capacity when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The quiver design allows for easy removal or repositioning of arms that may be obstructing the view. The modular structure enables selective extraction of arms from the quiver body when they interfere with the archer's line of sight, while leaving the remaining arms in place for continued storage.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If prior art quivers are used, then arrow storage is provided, but the covering of arrowheads is not adequately addressed

Engineering Contradiction:
Improvearrow storageVSAvoidarrowhead exposure
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The quiver arms are designed to nest against each other and against the stock when folded. The arms themselves provide a protective enclosure for the arrowheads, with the structure of the arms creating a nested configuration that shields the dangerous arrowhead portions while maintaining access to the arrow shafts for quick retrieval.

Inventive Principle:
Principle #7Nested doll (Nesting)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The apparatus provides efficient storage for multiple arrows, improves the archer's line of sight, and protects arrowheads during storage, addressing the bulkiness and visibility issues of prior designs.

Implementation Method 1

the selectively attaching means comprises a magnet fixed to the second leg so that when the first and second leg are pivoted together, the magnet attaches the first leg to the second leg

AI summary

An apparatus for crossbows. The crossbow has a stock attached to a bow and the bolt has an arrowhead attached to a shaft. The apparatus includes an arrowhead bracket attached to the stock, the arrowhead bracket having a first arm containing a first receptacle and a second arm containing a second receptacle. The apparatus may include a hood operatively attached to a cap, the hood being operatively configured to receive the arrowhead. The hood may be engagable with the first or second receptacle. The apparatus may contain a brace positioned on one side of the stock and having a first leg pivotally attached to a second leg and wherein said first leg is configured to engage the shaft of the bolt. The apparatus may also include a selective attachment member that will selectively attach the first and second leg together when the legs are pivoted together.
