Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pins are inserted into insertion portions using conventional methods, then pins can be inserted, but the insertion process is slow and unreliable

Engineering Contradiction:

Improvepin insertion reliabilityVSAvoidpin insertion speed

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent applies vibration to the pin receiving member to facilitate pin insertion. The vibration causes pins to move and align with insertion portions, enabling reliable and rapid insertion without complex mechanical pushing mechanisms.

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The patent replaces conventional mechanical insertion methods with a magnetic field-based system. Magnets are used to attract and guide pins into insertion portions, eliminating the need for mechanical pushing or pressing mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If conventional methods are used to remove remaining pins, then pins can be removed, but the removal process is slow and inefficient

Engineering Contradiction:

Improvepin removal speedVSAvoidremoval device complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent uses magnetic fields to replace mechanical removal mechanisms. Magnets attract remaining pins and move them to designated removal areas, eliminating the need for complex mechanical scraping or picking devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic field as an intermediary to transfer and move pins. The magnetic field acts as a mediator that can easily move pins from insertion portions to removal areas without direct mechanical contact.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If mechanical vibration is used for pin insertion, then pins can be inserted, but the method is complex and less efficient

Engineering Contradiction:

Improvepin insertion efficiencyVSAvoidinsertion device complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical vibration-based insertion with magnetic field-based insertion. Magnets positioned near insertion portions attract pins directly into the holes, eliminating the need for vibration mechanisms and reducing device complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
