Solution Overview

Problem

Existing fishing tackle, particularly diver sinking type, lacks effective three-dimensional positioning control, leading to interference and tangling issues when multiple fishermen operate in close proximity, and existing solutions require tools for adjustments, making them cumbersome and impractical in various conditions.

Innovation Solution

A hydrodynamic fishing device with a pivotally mounted plate positioning controller that provides tactile and audible indexing for manual adjustment of depth and lateral positioning, allowing for precise control without tools, using a detent arrangement and a manually graspable weighting ridge for easy operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If mechanical fasteners with tools are used for adjustments, then positioning control is achieved, but ease of operation deteriorates due to tool requirements and difficulty in manipulation

Engineering Contradiction:

Improvepositioning control precisionVSAvoidadjustment ease

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the traditional mechanical fastener system requiring screwdrivers with a cam mechanism that can be adjusted by hand. The cam's curved surface allows direct manual manipulation to achieve precise positioning control without tools, resolving the contradiction between precision and ease of operation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cam mechanism is designed to be self-adjusting through direct manual operation. The fisherman can easily grasp and rotate the cam body to reposition weights, making the system self-serviceable without external tools or complex manipulation procedures.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If uncontrolled fastener tightening and loosening is used, then adjustment flexibility is achieved, but reliability deteriorates due to inconsistent operation

Engineering Contradiction:

Improveadjustment flexibilityVSAvoidoperational consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The cam mechanism incorporates detent elements that provide tactile and audible feedback during rotation. These detents engage at specific intervals to indicate precise positioning, giving the operator feedback on the cam's rotational position and ensuring consistent, reliable adjustments rather than uncontrolled movement.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The cam mechanism transitions from a static fastened state to a dynamically adjustable state through controlled rotation. The detent system allows the cam to rotate freely for adjustment but locks into predetermined positions, providing both flexibility and operational consistency.

Inventive Principle:

Principle #15Dynamics

3Productivity

If multiple fishermen operate in close proximity, then fishing productivity is improved, but harmful factors increase due to line interference and tangling

Engineering Contradiction:

Improvefishing productivityVSAvoidline interference

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The cam mechanism allows each fisherman to independently and precisely control the lateral position of their specific fishing line by adjusting weight positions along the arc. This local control capability enables multiple fishermen to operate in close proximity without line interference, as each can maintain their line's unique path.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The adjustable cam mechanism enables dynamic repositioning of weights to change the lateral path of each fishing line. This dynamic control allows fishermen to adapt line positions in real-time to avoid interference with neighboring lines while maintaining productive fishing operations.

Inventive Principle:

Principle #15Dynamics

AI summary

A hydrodynamic fishing device includes a plate that changes attitude as the plate passes through a body of water. A plate positioning controller is pivotally mounted to the plate and is indexable relative to the plate by direct application of manual force so as to assume a plurality of predetermined adjustment positions. The adjustment positions establish different paths of travel of the plate as the plate passes through a body of water.
