Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If blind connection systems are used for automated assembly, then productivity is improved, but the system cannot compensate for large misalignments along perpendicular directions

Engineering Contradiction:
Improveautomated assemblyVSAvoidalignment accuracy
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent employs a movable connector component that can dynamically adjust its position along the insertion direction to compensate for misalignments. The connector includes a movable body that shifts relative to the fixed body, enabling the system to adapt to position variations while maintaining automated assembly capabilities

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the positional parameter of the connector components by introducing a movable body that can translate along the insertion direction. This parameter change allows the system to compensate for misalignments up to ±4 mm while preserving automated assembly productivity

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If blind connection systems are used for automated assembly, then ease of operation is improved, but the system cannot compensate for misalignments along the insertion direction

Engineering Contradiction:
Improveautomated connectionVSAvoidconnection stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The movable connector body dynamically adjusts its position along the insertion direction to compensate for misalignments, ensuring reliable electrical contact while maintaining ease of automated operation. The dynamic adjustment mechanism allows the system to self-correct position errors without human intervention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connector system performs self-alignment through the movable body that automatically compensates for misalignments during the insertion process. This self-service mechanism ensures connection reliability while maintaining automated operation without requiring external adjustment devices

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If slanted surfaces are used for alignment, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improvecoaxial alignmentVSAvoidconnector structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses a dynamic movable body instead of complex fixed alignment structures. The slanted surfaces guide the initial engagement, but the movable body completes the alignment process through controlled movement, achieving coaxial alignment with simpler overall device architecture

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable body acts as an intermediary element between the slanted surfaces and the final coaxial alignment. It receives the guidance from the slanted surfaces and translates this into precise positioning, reducing the complexity of the alignment mechanism while maintaining manufacturing precision

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If elastic means are added for compensation, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvemisalignment compensationVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The elastic means enable the connector body to dynamically adjust its position in response to misalignments. The elastic deformation provides adaptive compensation for position variations while maintaining a relatively simple system structure compared to rigid adjustment mechanisms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic means change the positional parameter of the connector body through elastic deformation. This allows the system to adapt to various misalignment conditions while using a simple elastic element rather than a complex adjustment mechanism, improving adaptability without significantly increasing device complexity

Inventive Principle:
Principle #35Parameter changes

AI summary

The present invention refers to a method for making a blind connection between a main first and a main second connector, wherein, thanks to the particular geometry of the main first and second connectors, a displacement of the main second connector is induced and coarse coaxial alignment with the main first connector is obtained. This method allows correction of large misalignments between the two connectors, because displacement and alignment of the main second connector are already guided during approaching of the two connectors. The present invention also refers to a method for making a blind connection between a main first and second connector, wherein the positions of the two connectors can be automatically adjusted so as to make them parallel to each other. The present invention finally refers to the corresponding blind connection systems.
