Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If sorted tools and attachments are presented to the user in predetermined order or locations, then tool selection efficiency is improved, but human errors such as placing tools in wrong bins or selecting incorrect tools still occur leading to assembly inaccuracies

Engineering Contradiction:
Improvetool selection efficiencyVSAvoidassembly accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces the mechanical sorting system with an image recognition and neural network-based identification system. The smart tool uses cameras to capture images of attachments, and a neural network processes these images to automatically identify and verify the correct attachment is selected, eliminating reliance on manual sorting and human visual inspection.

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

Solution Approach 2:

The system enables self-verification by having the smart tool automatically capture images of the selected attachment, process them through the neural network, and verify correctness without human intervention. The system serves itself by autonomously identifying and validating the attachment selection.

Inventive Principle:
Principle #25Self-service

2Device complexity

If manual tool selection and force application are used, then system complexity is reduced, but assembly precision and consistency deteriorate due to human errors in tool selection and force application

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent replaces manual mechanical operations with automated image processing and neural network analysis. The smart tool automatically captures images, processes them through computational algorithms, and uses the results to control force application, substituting human cognitive and manual operations with automated electronic systems.

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

Solution Approach 2:

The system implements feedback by capturing images of the selected attachment, processing them through the neural network to identify the attachment type, and using this information to automatically adjust and control the force application during assembly operations, ensuring precision through closed-loop control.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If image processing and neural network analysis are implemented in the smart tool, then tool identification accuracy is improved, but device complexity and processing time increase

Engineering Contradiction:
Improvetool identification accuracyVSAvoidsmart tool complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The neural network is pre-trained on a comprehensive dataset of attachment images before deployment in the smart tool. This preliminary training allows the network to perform rapid and accurate identification during actual use, reducing the computational burden and complexity during real-time operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses image copies (photographs) of the physical attachments as the basis for identification. Instead of directly analyzing physical characteristics, the smart tool captures optical images and processes these digital copies through the neural network, simplifying the identification process while maintaining high accuracy.

Inventive Principle:
Principle #26Copying
