Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional hard plastic trays with added routing structures are used, then structural strength is improved, but ease of operation and fiber accessibility deteriorate

Engineering Contradiction:
Improvestructural strengthVSAvoidfiber accessibility
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The patent employs flexible foil elements instead of rigid plastic structures to manage optical fibers. These thin film elements can be easily manipulated and adapted to different configurations, improving fiber accessibility while maintaining sufficient structural support through the flexibility and conformability of the foil material.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The fixation elements are designed to be movable and adjustable rather than fixed and rigid. This allows the fiber management system to adapt dynamically during installation and operation, enabling easier fiber routing and accessibility while maintaining structural integrity through controlled flexibility.

Inventive Principle:
Principle #15Dynamics

2Reliability

If fixation elements are added to mount fibers, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvefiber retentionVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into the fixation elements themselves. The foil elements combine fiber mounting, routing guidance, and retention functions in a single component, reducing the number of separate parts needed while maintaining reliable fiber retention through the multi-functional design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fixation elements are designed as universal components that can serve multiple purposes: mounting fibers to the tray, guiding fiber routing, providing mechanical retention, and adapting to different fiber configurations. This multi-functionality reduces overall system complexity while ensuring reliable fiber management.

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

3Ease of operation

If flexible foil elements are used, then ease of operation is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvefiber handlingVSAvoidfoil fabrication
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent utilizes specific material parameters of the flexible foil, such as its elasticity, thickness, and adhesive properties, to achieve both ease of operation and acceptable manufacturing tolerances. By carefully selecting and controlling these material parameters, the system achieves user-friendly fiber handling without requiring extremely tight manufacturing precision.

Inventive Principle:
Principle #35Parameter changes
