Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual operation is used for coupling and decoupling, then safety personnel can access the coupling device in emergencies, but the decoupling process is slow and requires continuous human intervention

Engineering Contradiction:
Improveemergency safetyVSAvoiddecoupling speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The coupling device is equipped with a sensor that automatically detects when the test object is removed, and a actuator that automatically executes the decoupling action without requiring manual intervention from safety personnel or continuous power supply, enabling the system to serve itself in emergency situations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operation with an automated sensor-actuator system that detects the test object's removal and triggers decoupling automatically, eliminating the need for continuous human intervention while maintaining emergency safety

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

2Extent of automation

If power-operated coupling devices are used, then decoupling can be automated, but the device requires continuous power supply and can injure installers during assembly or maintenance

Engineering Contradiction:
Improvedecoupling automationVSAvoidsafety risk during assembly
Core Design Contradiction:
Extent of automationVSObject-affected harmful factors

Solution Approach 1:

The sensor is positioned to detect the test object's removal before the actuator activates, ensuring that the decoupling action only occurs when it is safe to do so, preventing accidental activation during assembly or maintenance work

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The system performs preliminary detection of the test object's presence status before executing the decoupling action, ensuring that automation only activates when appropriate and preventing harmful accidental activation during assembly operations

Inventive Principle:
Principle #10Preliminary action

3Reliability

If conventional coupling devices are used, then connection can be established, but the decoupling process requires continuous power supply or manual intervention causing downtime

Engineering Contradiction:
Improveconnection reliabilityVSAvoiddowntime
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The coupling device automatically detects when the test object is removed through the sensor and triggers the actuator to execute decoupling without requiring continuous power supply or manual intervention, enabling rapid reset and minimizing downtime between test objects

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sensor continuously monitors the test object's presence status and triggers periodic decoupling actions only when needed, rather than requiring continuous power supply for maintaining the decoupled state, reducing energy consumption and downtime

Inventive Principle:
Principle #19Periodic action

AI summary

A coupling device (1) is provided with a first connection module (12) and a second connection module (14) which is detachably connectable to the first connection module (12). The first connection module (10) and the second connection module (14) form a connection (10). The coupling device (1) is configured to apply a coupling force that creates a connection between the first connection module (12) and the second connection module (14), and to apply a decoupling force that releases the connection. The decoupling force and the coupling force are applied from the first connection module (12) to the second connection module (14), and the decoupling force opposes the coupling force. The coupling force is provided by a pneumatic, hydraulic, electric, or electromagnetic actuator (20) provided on the first connection module (12).The decoupling force is provided by a mechanical, electrostatic, or magnetic storage device (24) that can absorb, store, and release some of the energy supplied by the coupling force. The coupling force is provided by a coupling mechanism, and the decoupling force is provided by a decoupling mechanism. The decoupling mechanism and the coupling mechanism form a single unit.
