Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional LC-type optical-fiber adapter is used, then optical signal transmission is achieved, but additional functions such as electric power transmission are not provided

Engineering Contradiction:
Improvefunctional versatilityVSAvoidadapter structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines optical signal transmission and electric power transmission functions into a single adapter body. The adapter integrates optical fiber receptacles for light signal transmission and conductive terminals for electrical connection, allowing both functions to coexist in one device without requiring separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adapter is designed to perform multiple functions simultaneously: it serves as both an optical connector for signal transmission and an electrical connector for power transmission. The universal design allows the same adapter housing to accommodate both optical and electrical connection requirements.

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

2Adaptability or versatility

If conductive terminals are added to enable electric power transmission, then functional versatility is improved, but device complexity increases

Engineering Contradiction:
Improvedual transmission capabilityVSAvoidinternal structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adapter internally segments different transmission paths: optical fibers are positioned in specific receptacles for light transmission, while conductive terminals are arranged in designated areas for electrical connection. This segmentation allows independent optimization of each function's pathway without interfering with the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent utilizes spatial arrangement within the adapter body to accommodate both optical and electrical components. Conductive terminals are positioned in specific regions (such as side walls or base areas) while optical fibers occupy central receptacles, creating a three-dimensional layout that efficiently packs multiple functions without excessive complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If positioning structures are added for conductive terminals, then transmission stability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly process
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The adapter includes pre-formed positioning structures such as positioning holes, guiding rails, and engagement protrusions that are integrated into the adapter body during manufacturing. These features are prepared in advance to guide the correct placement of conductive terminals and optical fibers, ensuring proper alignment and stable connection before final assembly.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Positioning structures act as intermediaries between the adapter body and the conductive terminals/optical fibers. Features like engagement protrusions on the adapter body mate with corresponding recesses on the terminals, providing mechanical guidance and securing the components in their correct positions during assembly and operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
