Solution Overview

Problem

Current fiber optic communication systems lack enhanced connectivity options within enclosures, which limits the flexibility and robustness of fiber optic network connections, particularly in outdoor environments where conventional indoor connectors are not sufficient.

Innovation Solution

The system includes a modular enclosure design with a sealant arrangement that accommodates fiber optic connection modules, providing sealed ports for routing cables and modules, and anchoring structures for securing these modules within the enclosure, enabling compatibility with hardened connectors and various fiber optic configurations, including passive power splitters and wavelength division multiplexing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional indoor connectors are used in fiber optic communication systems, then the system is simpler to implement, but the connectivity options and robustness are insufficient for outdoor environments

Engineering Contradiction:
Improveconnectivity robustnessVSAvoidconnector compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The enclosure is designed with multiple types of connectors (SC, LC, hardened connectors) and connection modules that can accommodate different fiber optic configurations. The sealant arrangement with multiple ports and the modular design enable the system to support various connector types and fiber arrangements, making it universally applicable for both indoor and outdoor environments.

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

2Adaptability or versatility

If the enclosure provides multiple connectivity options and hardened connector support, then the adaptability and robustness improve, but the device complexity increases

Engineering Contradiction:
Improveconnector compatibilityVSAvoidenclosure structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The enclosure is divided into modular components including the base, dome, sealant arrangement, and multiple connection modules. Each module can be independently configured and installed, allowing the system to provide complex functionality while maintaining ease of assembly and maintenance through standardized modular units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Connection modules are nested within the enclosure structure, with each module containing connectors, adapters, and mounting structures. The modular design allows smaller functional units to be integrated within the larger enclosure system, reducing overall complexity while maintaining versatility.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If the sealant arrangement is pressurized to seal cable ports, then the environmental sealing improves, but the manufacturing and assembly precision requirements increase

Engineering Contradiction:
Improveenvironmental sealingVSAvoidsealant pressurization
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The sealant arrangement incorporates a pressurization mechanism that allows the sealant to be dynamically adjusted to different pressure levels. This dynamic pressurization capability enables the seal to adapt to variations in assembly tolerances and environmental conditions, achieving reliable sealing without requiring extremely tight manufacturing precision.

Inventive Principle:
Principle #15Dynamics
