Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If hard plastic constructions are used for fiber optic trays, then structural strength is improved, but fiber damage risk increases

Engineering Contradiction:

Improvestructural strengthVSAvoidfiber damage risk

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent replaces hard plastic constructions with flexible film elements that have appropriate bend radii. These flexible films provide the necessary structural support while being gentle on the optical fibers, eliminating the fiber damage risk associated with hard plastic trays.

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

If complex routing structures are added to manage fibers, then fiber management capability is improved, but device complexity increases

Engineering Contradiction:

Improvefiber management capabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the fiber management system into modular components including fixation tags, mounting structures, and cable assemblies. Each component performs a specific function independently, simplifying the overall system while maintaining comprehensive fiber management capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixation tags are pre-formed with specific geometries and mounting structures are pre-positioned within the closure. This preliminary preparation eliminates the need for complex field assembly and routing operations, reducing device complexity while improving management capability.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If fixation elements are added to secure fibers, then fiber stability is improved, but installation time increases

Engineering Contradiction:

Improvefiber stabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The fixation tags are designed to be self-adhering or self-locking to the mounting structures. Once the cable assembly is inserted, the fixation elements automatically secure the fibers without requiring additional manual attachment steps, maintaining fiber stability while minimizing installation time.

Inventive Principle:

Principle #25Self-service
