Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external power sources are used for LED light fixtures, then the LEDs can be powered reliably, but the fixture design becomes bulkier and heavier

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidfixture weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The patent integrates the power conversion circuitry directly into the LED fixture substrate, merging previously separate external power sources with the LED module. This consolidation eliminates the need for bulky external power supplies while maintaining reliable AC-to-DC conversion functionality within the fixture itself.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The LED fixture substrate is designed to perform multiple functions: it serves as both the mechanical mounting platform for LEDs and as the circuit board for power conversion. The substrate integrates LED mounting areas, AC input circuitry, rectification, and DC output pathways, making the fixture self-contained and eliminating separate power supply components.

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

2Reliability

If separate communication networks are deployed for data transmission, then data can be transmitted reliably, but the deployment cost becomes very expensive

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoiddeployment cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The lighting infrastructure is designed to serve dual purposes: providing illumination and enabling data transmission. By integrating communication transceivers into the LED fixture and using the existing electrical wiring for power delivery, the system eliminates the need for separate communication networks while maintaining reliable data transmission capabilities.

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

Solution Approach 2:

The patent uses the existing electrical infrastructure as an intermediary for both power delivery and data communication. The wiring that was traditionally used only for power now serves as a dual-purpose medium, carrying both electrical power to the LEDs and communication signals to and from the transceivers integrated in the fixtures.

Inventive Principle:
Principle #24Intermediary (Mediator)
