Solution Overview

Problem

Existing bait fish holders attach externally, causing unnatural rotation and obscuring the bait fish, presenting it in a less-than-ideal manner to game fish.

Innovation Solution

A bait fish holder with a mouth-insertion plug and radially extending arms connected to blades, providing rotational or oscillatory motion internally within the bait fish's mouth, enhancing natural presentation and securing the device internally.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external attachment devices (cap, cone, clamp, or cage) are used to attach the bait fish holder to the bait fish, then the device can be securely attached, but the bait fish is obscured and presented in an unnatural manner

Engineering Contradiction:
Improveattachment securityVSAvoidnatural appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The bait fish holder device is inserted into the mouth cavity of the bait fish, nesting the attachment device within the natural anatomy of the fish. This internal positioning allows secure attachment through the mouth without external protrusions, maintaining the natural appearance of the bait fish while ensuring reliable attachment.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If external attachment devices are used, then the device can be easily attached, but the rotation of the bait fish is not natural and the device obscures the bait fish

Engineering Contradiction:
Improveattachment easeVSAvoidnatural presentation
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The device nests within the mouth cavity, allowing simple insertion without complex external attachment mechanisms. The internal positioning ensures natural rotation and presentation while maintaining ease of attachment through straightforward insertion into the mouth.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

Instead of attaching the device externally to the bait fish, the invention inverts the approach by inserting the device internally into the mouth cavity. This inversion allows the attachment point to be hidden inside the fish's anatomy, maintaining natural appearance and movement while ensuring secure attachment.

Inventive Principle:
Principle #13The other way round (Inversion)

3Force

If the device is attached externally, then the rotational force can be externally imparted, but the bait fish presentation is less than ideal

Engineering Contradiction:
Improverotational force applicationVSAvoidpresentation quality
Core Design Contradiction:
ForceVSReliability

Solution Approach 1:

The invention inverts the force application approach by applying rotational force internally through the mouth cavity rather than externally. This internal force application maintains secure attachment while preserving natural bait fish presentation to game fish.

Inventive Principle:
Principle #13The other way round (Inversion)

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 internal attachment enhances the natural movement and presentation of the bait fish, increasing its attractiveness to game fish while minimizing the risk of the device being pulled out.

Implementation Method 1

The mouth-insertion plug is shaped and sized to fit within the mouth of a bait fish and to articulate with the internal tissues within the mouth, thus providing purchase to the interior of the mouth of the bait fish

Methodology Applied
Scientific EffectFriction: Friction

Implementation Method 2

The proximal end of the plug is connected to a plurality of arms extending substantially radially outward from the plug. Each of the arms is connected to a blade. The device provides rotational or oscillatory motion to a fish by predominant purchase of the device to the interior of the mouth of the bait fish

Methodology Applied
Scientific EffectHydrodynamic force: Drag
