Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional optical splitting solutions use splicing to connect optical fibers, then optical fibers can be connected to cover more users, but the implementation period becomes long and labor costs increase

Engineering Contradiction:
Improvecoverage of usersVSAvoidimplementation period
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The optical splitting device is divided into multiple independent modules (optical splitting modules, optical coupling modules, optical fiber adapter modules) that can be independently prepared and then quickly assembled together through simple plugging operations, eliminating the need for complex splicing operations on-site

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Optical fibers are pre-connected to adapters and modules during manufacturing or preparation phase, so that during actual deployment, operators only need to perform simple plugging operations rather than complex splicing, significantly reducing implementation time

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If conventional optical splitting solutions use splicing to connect optical fibers, then optical fibers can be connected, but implementation skill requirement increases and labor costs become high

Engineering Contradiction:
Improveconnection capabilityVSAvoidimplementation difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Optical fiber adapters serve as intermediary components that simplify the connection process. Instead of directly splicing optical fibers which requires high skill, the adapters provide a standardized interface that allows simple plugging operations while maintaining reliable optical connections

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is designed to be self-aligning and self-securing through the adapter mechanism, where the optical fibers automatically align and secure themselves when plugged into the adapter, reducing the need for skilled manual alignment and splicing operations

Inventive Principle:
Principle #25Self-service

3Productivity

If even optical splitters are used in conventional solutions, then optical splitting can be performed, but flexible power allocation for different user distributions cannot be achieved

Engineering Contradiction:
Improveoptical splitting capabilityVSAvoidpower allocation flexibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

Different modules within the optical splitting device have different splitting ratios (e.g., 1:2, 1:4, 1:8) tailored to specific local requirements. Each module can be configured with appropriate splitting ratios to match the user distribution in its specific area, enabling flexible and optimized power allocation

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The optical splitting device allows dynamic configuration by selecting and combining different modules with various splitting ratios. Operators can adapt the system configuration to match changing user distribution patterns and coverage requirements, making the system flexible and scalable

Inventive Principle:
Principle #15Dynamics

AI summary

The present invention provides an optical splitting apparatus. The optical splitting apparatus includes an enclosure and an even optical splitter and an uneven optical splitter that are disposed in the enclosure. A light inlet and a plurality of light outlets are disposed on the enclosure, and fiber adapters are disposed on the light outlets. The light inlet, the even optical splitter, the uneven optical splitter, and the light outlets are connected, so that optical paths are formed between the light inlet and the light outlets by using the even optical splitter and the uneven optical splitter. The light inlet is connected to at least one of a light input end of the even optical splitter and a light input end of the uneven optical splitter, and the fiber adapter on the light outlet is connected to at least one of a light output end of the even optical splitter and a light output end of the uneven optical splitter. This type of optical splitting apparatus may be used in coordination with an optical cable that has an optical fiber connector at an end, so that output optical power of each light outlet can be configured flexibly based on a user distribution status while plug-and-play is implemented. In this way, not only a long coverage distance is implemented, but also no optical signal resources are wasted and as many users as possible are covered.
