Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a simple adapter assembly is used to connect optical connectors, then the device complexity is reduced and ease of manufacture is improved, but the connection reliability deteriorates due to insufficient resistance to vibrations

Engineering Contradiction:
Improveconnection reliabilityVSAvoidadapter structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The adapter assembly is divided into distinct functional components: the adapter body, locking elements, and retaining elements. This segmentation allows each component to perform its specific function independently while maintaining overall connection reliability without excessive complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking elements are designed to be elastically deformable, allowing them to dynamically adjust during insertion and locking operations. This dynamic property enables reliable vibration resistance through elastic deformation rather than requiring complex rigid mechanical structures

Inventive Principle:
Principle #15Dynamics

2Reliability

If elastically deformable locking elements are used to provide vibration resistance, then the connection reliability is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvevibration resistanceVSAvoidlocking element precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The locking elements utilize elastic deformation properties by changing the material parameter from rigid to elastically deformable. This parameter change allows the structure to achieve vibration resistance through material elasticity rather than requiring high manufacturing precision of complex mechanical tolerances

Inventive Principle:
Principle #35Parameter changes

3Strength

If a locking arrangement with multiple components is implemented, then the connection strength is improved to prevent disconnection, but the device complexity increases

Engineering Contradiction:
Improveconnection strengthVSAvoidlocking arrangement complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The locking elements and retaining elements are integrated into a unified locking arrangement that works together to provide connection strength. This merging of functions into a coordinated system achieves strong vibration resistance without the complexity of separate independent locking mechanisms

Inventive Principle:
Principle #5Merging (Combining)
