Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual cutting and visual inspection methods are used to analyze internal quality of food products, then operators can directly observe defects, but the process becomes tedious, time-consuming, and imprecise

Engineering Contradiction:
Improvedefect detection precisionVSAvoidanalysis time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical cutting and visual inspection with an automated optical imaging system. The cutting means automatically slice food products, and imaging means capture images of the cut surfaces, eliminating the need for manual observation and significantly reducing analysis time while improving precision through automated defect detection algorithms

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates optical copies (images) of the cut surfaces of food products. Instead of manually examining each cut surface, the system captures images and stores them in a database, allowing for rapid automated analysis and comparison with reference images to detect defects with high precision and speed

Inventive Principle:
Principle #26Copying

2Reliability

If manual visual inspection is used to check for internal defects, then operators can identify visible defects, but the method lacks precision and reliability due to human error

Engineering Contradiction:
Improveanalysis reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the human visual inspection system with an automated optical imaging and image processing system. This substitution eliminates human error and subjectivity, providing consistent and reliable defect detection. The system includes imaging means, processing means, and a database of reference images that work together to automatically identify defects with high reliability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements a feedback mechanism where collected images are compared with reference images stored in a database. The processing means analyzes the images and provides feedback on defect detection, allowing for continuous validation and improvement of detection accuracy. This feedback loop ensures reliable and consistent defect identification across different samples

Inventive Principle:
Principle #23Feedback

3Productivity

If automated cutting and imaging systems are implemented to rapidly analyze food products, then analysis speed and precision improve, but the device complexity increases

Engineering Contradiction:
Improveanalysis productivityVSAvoiddevice structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the analysis system into distinct functional modules: cutting means for slicing food products, imaging means for capturing images, processing means for analyzing images, and a database for storing reference images. This segmentation allows each component to be optimized independently while working together to achieve high productivity and automated analysis

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent designs the system with multi-functional components that can handle various food products and defect types. The imaging means can capture different types of defects, the processing means can analyze multiple image parameters, and the database can store diverse reference images, making the system universally applicable to different analysis requirements while maintaining streamlined operation

Inventive Principle:
Principle #6Universality (Multi-functionality)
