Solution Overview

Problem

The existing methods for extracting pin bones from fish fillets often result in either the pin bones being torn or fish flesh being removed along with them, leading to yield loss and production line inefficiencies due to the need for slow extraction speeds and additional handling steps.

Innovation Solution

A method and device that utilize a tool with adjustable displacement speeds relative to the fillet, allowing for slower extraction speeds over areas with pin bones and faster speeds over areas without, optimizing the extraction process and reducing downtime in fish fillet production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the pin bone is extracted at a relatively slow speed, then the pin bone can be removed without tearing or pulling fish flesh, but the production line efficiency decreases and multiple extractors are needed

Engineering Contradiction:

Improvepin bone extraction qualityVSAvoidproduction line efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The tool's displacement speed is made dynamic and adjustable, allowing it to operate at relatively low speeds when extracting pin bones to ensure quality removal without tearing, and at higher speeds when moving between fillets or processing areas without pin bones, thereby maintaining production line efficiency

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The displacement speed parameter of the tool is changed based on the processing requirements - using lower speeds during pin bone extraction to prevent damage and higher speeds during non-extraction phases to maximize productivity

Inventive Principle:

Principle #35Parameter changes

2Productivity

If the tool is displaced at a relatively high speed, then production line efficiency increases, but the pin bones are torn or fish flesh is pulled out with them

Engineering Contradiction:

Improveproduction line efficiencyVSAvoidpin bone extraction quality

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The tool's displacement speed is dynamically adjusted based on real-time detection - operating at high speeds when no pin bones are present and automatically reducing to low speeds when pin bones are detected, ensuring both efficiency and extraction quality

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses feedback from pin bone detection mechanisms to automatically adjust the tool's displacement speed, creating a closed-loop control system that maintains optimal extraction conditions

Inventive Principle:

Principle #23Feedback

3Productivity

If multiple pin bone extractors are used to maintain production capacity, then productivity is maintained, but device complexity and costs increase

Engineering Contradiction:

Improveproduction line capacityVSAvoidnumber of extractors

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

A single extractor is equipped with dynamic speed control capabilities, allowing it to process pin bones at low speeds and move between fillets at high speeds, replacing the need for multiple static extractors and simplifying the production line

Inventive Principle:

Principle #15Dynamics

AI summary

Method for extracting pin bones from a fillet wherein the pin bones are extracted by a tool having a certain speed relative to the fillet and wherein the tool is displaced at different relative speeds along a first fillet portion where the fillet has pin bones and along a second fillet portion where the fillet has no pin bones.
