Dissolvable Fishhook Coating for Aquatic Animal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fishing hooks and lines are non-dissolvable, leading to prolonged harm and death for aquatic animals, as they take months to years to decompose, causing irreparable damage and environmental pollution.
Innovation Solution
Development of fishhooks and fishing lines made from dissolvable materials with coatings that break down in water or bodily fluids, allowing them to dissolve within a specified time frame, preventing long-term harm to fish and reducing environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional non-dissolvable fishing hooks and lines are used, then they provide long-lasting durability and strength, but they cause prolonged harm and death to aquatic animals and create environmental pollution
Solution Approach 1:
The patent changes the material parameters of fishing hooks and lines from traditional non-dissolvable materials (stainless steel, nylon) to dissolvable materials that break down in water. The hooks are made from water-soluble materials and coated with dissolvable substances, while lines are made from biodegradable materials, fundamentally altering the decomposition time parameter from centuries to days or weeks.
Solution Approach 2:
The invention employs disposable fishing hooks and lines designed for short-term use only. These dissolvable hooks and lines are intended to be used once and then naturally decompose in the environment, eliminating the need for retrieval and preventing long-term persistence in aquatic ecosystems that causes harm to animals.
2Object-affected harmful factors
If dissolvable materials are used for fishing hooks and lines, then they reduce harm to aquatic animals by decomposing quickly, but they may have reduced strength and durability during use
Solution Approach 1:
The patent employs composite material structures where dissolvable hooks are coated with protective substances that enhance their strength and durability during use. The coating acts as a protective layer that prevents premature degradation while maintaining the underlying dissolvable structure, creating a composite that balances both strength and biodegradability.
Solution Approach 2:
The invention creates materials with dynamic properties that adapt to environmental conditions. The dissolvable hooks and lines maintain their structural integrity and strength when dry or in air during the fishing process, but automatically activate their dissolvable properties when exposed to water for extended periods, providing context-dependent material behavior.
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 dissolvable fishhooks and lines ensure minimal harm to fish by dissolving within 24 hours to 48 hours, reducing the risk of injury or death and significantly shortening the time for environmental degradation, thus promoting sustainable fishing practices.

AI summary
A fishhook including a shank, an eye attached to the shank, a bend attached to the shank and terminating in a point. The fishhook further including a core of a dissolvable material, and at least one coating or layer on the core. The at least one coating is dissolvable in water, saltwater, or the stomach acid of an animal. A fishing line includes a line composed of a dissolvable material, and a coating coated on said line composed of a dissolvable material.
