Detachable Game Tracking Apparatus with Forward Barbs

Solution Overview

Problem

Existing detachable arrow-mounted game tracking devices fail to securely attach and remain with the game animal upon impact due to rebound energy and detachment issues, leading to ineffective tracking.

Innovation Solution

A detachable tracking apparatus with a stopping component, such as wings or barbs, that securely attaches to the arrow and a securing component with reverse barbs to prevent rebound, ensuring the device remains with the target animal after impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a detachable transmitting device uses hooks to attach to the game animal, then the device can be detached from the arrow, but the device fails to securely attach and rebounds off the animal due to impact energy

Engineering Contradiction:

Improveattachment reliabilityVSAvoidrebound force

Core Design Contradiction:

ReliabilityVSForce

Solution Approach 1:

The patent inverts the traditional barb orientation by using barbs that angle forward toward the front of the arrow rather than backward. This forward-angling design allows the barbs to penetrate the animal's tissue on impact and maintain secure attachment by engaging with the tissue in the direction of arrow travel, effectively counteracting the rebound force that causes conventional detachable devices to fail.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent converts the harmful rebound force generated by arrow impact into a beneficial securing mechanism. The forward-angling barbs are designed to be driven into the animal's tissue by the impact force itself, transforming the potentially detrimental rebound effect into the very force that secures the transmitting device to the target.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Speed

If the arrow travels at high speed (250-450 fps), then the transmitting device can be delivered to the target, but the extreme impact energy causes the detachable device to rebound or fall out

Engineering Contradiction:

Improvearrow speedVSAvoiddevice retention

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent inverts the traditional barb orientation by using barbs that angle forward toward the front of the arrow rather than backward. This forward-angling design allows the barbs to penetrate the animal's tissue on impact and maintain secure attachment by engaging with the tissue in the direction of arrow travel, effectively counteracting the rebound force that causes conventional detachable devices to fail.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the geometric parameters of the attachment mechanism by altering the barb angle from the conventional backward orientation to a forward orientation. This parameter change fundamentally alters how the device interacts with the target tissue during high-speed impact, enabling reliable retention despite the extreme forces involved.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the transmitting device is pulled out by the animal rubbing against obstacles or instinctively pulling, then the animal can move freely, but the tracking function fails

Engineering Contradiction:

Improveanimal movement freedomVSAvoidtracking functionality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent inverts the traditional barb orientation by using barbs that angle forward toward the front of the arrow rather than backward. This forward-angling design allows the barbs to penetrate the animal's tissue on impact and maintain secure attachment by engaging with the tissue in the direction of arrow travel, effectively counteracting the rebound force that causes conventional detachable devices to fail.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent employs a multi-component attachment system with barbs, springs, and curved engagement surfaces that work together to provide secure, multi-directional retention. The curved geometry of the spring-loaded barb mechanism allows it to accommodate animal movement while maintaining firm engagement, preventing pullout during rubbing or instinctive pulling behaviors.

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A tracking apparatus secures a transmitting device onto a target game animal. The tracking apparatus engages with a target and separates the apparatus from the arrow. The apparatus includes a transmitting device for transmitting a signal to a receiving device; a stopping component for detaching the tracking apparatus from the arrow after the arrow collides with the target; and a securing component for securing the tracking apparatus to the target, said securing component including barbs angled towards the rear of the arrow for stopping rebound motion of the tracking apparatus after the arrow collides with the target. In one embodiment, the barbs are reinforced with reinforcing arms. In another embodiment, the securing component includes a torsion spring. In another embodiment, the stopping component includes one or more wings with a front edge facing the front of the arrow that is relatively perpendicular to the axis of the arrow.
