Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If copper UTP cables are used for data transmission, then existing infrastructure can be maintained, but power efficiency and data rate performance deteriorate at distances beyond 100m

Engineering Contradiction:

Improvepower efficiencyVSAvoiddata rate

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The patent segments the cabling infrastructure into two distinct functions: optical fiber cables dedicated to data transmission and copper UTP cables dedicated to power transmission. This segmentation allows each cable type to operate in its optimal performance range, with fiber providing high-speed data over long distances and copper providing efficient power delivery to active zone equipment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies multi-functionality by having the telecommunications room equipment serve dual purposes: it acts as an optical transceiver for data communication while simultaneously functioning as a power sourcing device for delivering power over copper cables to zone enclosures, thereby eliminating the need for separate power infrastructure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If UTP cables are removed and replaced with optical fiber, then bandwidth and power efficiency improve, but installation complexity and cost increase

Engineering Contradiction:

ImprovebandwidthVSAvoidcable replacement complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts the data transmission function from the copper cable infrastructure and assigns it exclusively to optical fiber cables, while retaining copper cables for their optimized function of power delivery. This extraction allows the system to leverage the superior bandwidth of fiber without requiring complete infrastructure replacement.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using copper cables for both data and power (traditional approach), the patent inverts the approach by using optical fiber for data and copper for power, reversing the conventional assignment and achieving superior overall system performance.

Inventive Principle:

Principle #13The other way round (Inversion)

3Loss of energy

If active equipment is moved to zone enclosures, then power delivery efficiency improves, but the need for power sources near zone enclosures creates installation challenges

Engineering Contradiction:

Improvepower delivery efficiencyVSAvoidinstallation ease

Core Design Contradiction:

Loss of energyVSEase of manufacture

Solution Approach 1:

The patent introduces an intermediary power delivery mechanism where power is transmitted over the existing copper cable infrastructure from the telecommunications room to zone enclosures. This intermediary approach enables active equipment placement at zone enclosures without requiring physical power sources to be installed at each location, thus maintaining installation ease while achieving power delivery efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)
