Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual alignment is used to connect the cable leading end to the connector, then positioning accuracy is improved, but work efficiency decreases

Engineering Contradiction:
Improvealignment accuracyVSAvoidwork efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces manual mechanical alignment operations with an automated system comprising a visual device for detection, a robot arm for positioning, and a controller for coordination. The visual device captures images of the cable leading end and connector, the controller processes these images to determine precise positions, and the robot arm executes automated gripping and alignment, thereby maintaining high positioning accuracy while significantly improving work efficiency

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

Solution Approach 2:

The system enables the cable leading end to be automatically positioned and aligned through the coordinated operation of the visual device, robot arm, and controller. The robot arm autonomously grips the cable leading end based on visual feedback, automatically adjusts its position to achieve accurate alignment with the connector, and completes the connection without human intervention, allowing the system to serve itself in the alignment task

Inventive Principle:
Principle #25Self-service

2Productivity

If the cable leading end is directly gripped, then connection speed is improved, but positioning accuracy deteriorates due to cable deformation

Engineering Contradiction:
Improveconnection speedVSAvoidpositioning accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by having the visual device capture images of the cable leading end and connector before the robot arm performs gripping and alignment. The controller processes these pre-captured images to determine the precise positions and orientations, allowing the robot arm to execute accurate movements in one go, thus achieving both high connection speed and positioning accuracy without iterative adjustments

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback through the visual device that continuously monitors and provides image data about the cable leading end and connector positions. The controller uses this visual feedback to calculate precise positioning information and guide the robot arm's movements, ensuring accurate alignment while maintaining fast connection speed through automated real-time adjustment

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If multiple robots are used to grip and move the cable, then positioning accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a single robot arm that performs multiple functions: gripping the cable leading end, positioning it accurately, aligning it with the connector, and completing the connection. This multi-functional robot arm replaces the need for multiple specialized robots, maintaining high positioning accuracy while significantly reducing system complexity

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

Solution Approach 2:

The system merges the functions of multiple robots into a single integrated robot arm system. The robot arm combines gripping mechanisms, positioning capabilities, and alignment functions that would traditionally require separate robots. The visual device and controller are also integrated to work in unison with the robot arm, creating a unified system that achieves high precision with reduced complexity

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If a cable holding tool is slid relative to the cable to make it stand up, then connection speed is improved, but device complexity increases

Engineering Contradiction:
Improveconnection speedVSAvoidapparatus complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies self-service by using the robot arm's own gripping and positioning capabilities to make the cable stand up, rather than requiring a separate cable holding tool. The robot arm grips the cable leading end and uses its controlled movements to position the cable in the required orientation, thereby achieving fast connection speed while avoiding the added complexity of additional specialized tools

Inventive Principle:
Principle #25Self-service
