Solution Overview

Problem

Existing fishhook remover aids expose anglers to slime, dirt, and sharp fins/scales, and require separate measuring devices, failing to provide a safe and efficient method for hook removal and fish sizing.

Innovation Solution

A handheld fishhook remover aid with a built-in ruler that securely holds a fish without direct contact, using Low Density Polyethylene and Dura Grip 6000 rubber for a sturdy yet flexible design, allowing safe and easy hook removal and fish measurement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional fishhook remover aids are used, then hook removal can be performed, but the angler's skin is exposed to slime, dirt, and sharp fins/scales

Engineering Contradiction:

Improveskin exposure to slime and sharp finsVSAvoiddirect contact requirement

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The device introduces an intermediary tool (the holder with clamping jaws) that mediates between the angler's hand and the fish. The angler operates the device without direct skin contact with the fish, while the holder's clamping jaws securely grip the fish's body. This resolves the contradiction by eliminating harmful skin exposure while maintaining ease of operation through the intermediary mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device segments the interaction into distinct functional zones: the holder body provides structural support and measurement, the clamping jaws provide secure grip, and the ruler provides measurement capability. This segmentation allows each component to address specific aspects of the problem, with the holder design specifically addressing skin protection while maintaining operational ease.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If traditional fishhook remover aids are used, then hook removal can be performed, but a separate measuring device is required

Engineering Contradiction:

Improvenumber of separate toolsVSAvoidfish size measurement

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The device merges three separate functions into one integrated tool: hook removal, fish measurement, and secure holding. The ruler is built into the holder body, eliminating the need for separate measuring devices. This merging reduces device complexity by consolidating multiple tools into one while maintaining measurement precision through the integrated ruler scale.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The holder is designed with multi-functionality, serving as both a secure gripping device and a measuring instrument. The ruler integrated into the holder body allows the same device used for hook removal to also measure fish size, demonstrating universality that reduces the number of separate tools needed while maintaining accurate measurement capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the fish is held securely for hook removal, then safe operation is achieved, but the angler must come into contact with the fish

Engineering Contradiction:

Improvesecure fish holdingVSAvoidskin contact with slime and fins

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The holder acts as an intermediary that provides secure fish holding without requiring the angler's skin to contact the fish. The clamping jaws grip the fish firmly for reliable hook removal, while the angler operates the device through the holder's handle, maintaining reliability while eliminating harmful skin contact.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If a built-in ruler is added to the fishhook remover aid, then fish measurement is integrated, but device complexity increases

Engineering Contradiction:

Improveintegrated measurement capabilityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ruler is merged with the holder body structure, integrating the measurement function into the existing device rather than adding a separate component. This merging increases adaptability by providing integrated measurement capability while minimizing the increase in device complexity through seamless integration into the existing holder design.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

One embodiment of the invention is a fishhook remover aid 100 that has a base 102 and a cover 170. The base 102 is longer than the cover 170. When reeling in a fish, an angler may first insert a fishing line 138 through a space 120 located on top portions 112, 114 of the cover 170. The fish is then urged along the base 102 and into the cover 170. Opposing rounded sides 108, 110 of the cover 170 are flexible, allowing the angler to grasp the fishhook remover aid with sufficient pressure on the fish to remove the fishhook 138 without damaging the fish in the process. The safe swift removal of the fishhook without the need for an angler's hand to come into direct contact with the fish thus occurs. The fishhook remover aid 100 has a built in ruler 134 located on the base 102 for measuring a length of the fish while the angler removes the fishhook.
