Fishing Apparatus Pivot Arm Spring-Loaded Hooking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fishing apparatuses have deficiencies such as direct connection of the hook line to the trigger, which interferes with operation, occupy significant space, and do not allow fish to swim with the hook before setting, leading to missed catches.
Innovation Solution
A fishing apparatus with a frame, pivot arm, and spring-loaded hooking mechanism where the hook line is not connected directly to the trigger, allowing the fish to swim before tripping, and a compact vertical orientation that can be stabilized by packing materials under the frame, featuring a flexible rod and spring-loaded lever mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the hook line is connected directly to the trigger, then the hook setting is rapid, but the trigger line interference prevents proper fish swimming and hook setting
Solution Approach 1:
The patent extracts the hook line connection from the trigger mechanism by introducing a separate trigger line that is independent from the hook line. The trigger line is connected to the trigger, while the hook line remains separate and connected to the pivot arm, eliminating the interference between the trigger line and hook line operation.
Solution Approach 2:
The patent introduces a trigger line as an intermediary element between the trigger and the pivot arm. This trigger line serves as a mediator that transmits the triggering action to the pivot arm without directly connecting the hook line to the trigger, allowing independent operation of each component.
2Device complexity
If the hooking mechanism is horizontal, then the structure is simple, but it occupies significant support surface area
Solution Approach 1:
The patent transitions the hooking mechanism from a horizontal orientation to a vertical orientation. The pivot arm pivots about a fulcrum in a vertical plane, and the spring-loaded lever acts vertically, changing the dimensional orientation from horizontal to vertical to reduce the support surface area requirement.
3Speed
If the trigger line is short, then the response is fast, but the fish cannot swim with the hook before setting
Solution Approach 1:
The patent implements preliminary action by allowing the pivot arm to pivot downward a certain distance before the trigger is tripped. This preliminary movement gives the fish time to swim with the hook in its mouth before the hooking mechanism is activated, improving the chance of successful hook setting.
Solution Approach 2:
The patent introduces dynamic behavior to the trigger line length by making it adjustable or variable. The trigger line length can be configured to provide sufficient slack for the pivot arm to pivot downward before tripping, allowing the fish to swim with the hook while maintaining responsive triggering when needed.
4Force
If the spring force is high, then the hook setting is strong, but the fishing line may break or the hook may be torn away
Solution Approach 1:
The patent applies parameter changes by adjusting the spring force to an optimal level that is sufficient to set the hook strongly but not so high as to break the fishing line or tear the hook from the fish's mouth. The spring force parameter is carefully controlled to balance these competing requirements.
Solution Approach 2:
The patent implements beforehand cushioning by designing the spring-loaded mechanism to provide controlled force that cushions the hook setting action. The spring gradually releases its energy to set the hook, preventing sudden excessive forces that could break the line or dislodge the hook, while still maintaining sufficient setting force.
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
Enables successful hook setting in the fish's mouth by allowing the fish to swim with the hook and maintaining tension to prevent escape, while being compact and stable for ice fishing.
Implementation Method 1
The spring bias on the lever maintains a tension on the fishing line that prevents the fish from escaping from the hook. The spring bias also gives slightly to the pull on the fishing line by the fish to prevent the fishing line from breaking and to prevent the hook from being torn away from the fish.
Implementation Method 2
The pivot arm pivots about a fulcrum that is supported by the frame. The flexible rod extends from one end of the pivot arm and supports the fishing line.
Implementation Method 3
when the trigger line trips the trigger, the lever and pull line rapidly pull the end of the pivot arm downward thus jerking the flexible rod upward
Implementation Method 4
The hooking mechanism includes a torsion spring and a wire frame, which is biased away from the hook end of the base

AI summary
The invention provides a fishing apparatus having a pivot arm mounted on a frame with a fishing line paid out on one end of the pivot arm via a flexible fishing rod and a hooking mechanism connected to the opposite end via a trigger line and a pull line. The hooking mechanism may resemble a mouse trap with a trigger connected to the trigger line arm a retaining arm engaging the trigger and retaining a spring-loaded arm in the set position. The spring-loaded arm is connected to the pull line. A fish trying to swim with the hook will cause the pivot arm to tip down, triggering the hooking mechanism. The spring-loaded arm pivots downward rapidly, pulling the pivot arm so that the fishing rod moves upward rapidly and sets the hook in the fish's mouth. The spring bias in the spring-loaded arm then keeps the fishing line under tension so that the fish doesn't release the hook without ripping the hook from the mouth.
