Innovation Solution

An LED-based illumination device is designed with a heat sink, a primary electrical circuit board, and a peripheral electrical circuit board that includes a radio frequency (RF) transceiver, enabling data communication and integrating light control, power conversion, data acquisition, and processing within a common housing, allowing for efficient heat dissipation and sensor integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If LED illumination devices are designed as standalone units, then manufacturing and installation are simple, but data collection and communication capabilities are lacking

Engineering Contradiction:
Improvedata collection and communication capabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional components (LED light engine, heat sink, primary circuit board, and peripheral circuit board with RF transceiver) into a single integrated illumination device. This merging approach enables data collection and communication capabilities while maintaining a unified device structure that manages complexity through functional integration rather than separate standalone units.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The illumination device is designed to perform multiple functions simultaneously: light emission, heat dissipation, data collection, and wireless communication. The peripheral circuit board with RF transceiver enables the device to communicate with external devices and receive control signals, making it a multi-functional smart lighting solution rather than a simple light source.

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

2Adaptability or versatility

If multiple circuit boards and components are integrated within the housing, then functionality is enhanced, but manufacturing precision and assembly difficulty increase

Engineering Contradiction:
Improveintegrated functionalityVSAvoidassembly precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The device is segmented into distinct functional modules: LED light engine, heat sink, primary circuit board, and peripheral circuit board. Each module is designed and manufactured separately with specific functions, then assembled together. This segmentation allows for specialized manufacturing of each component while maintaining overall system integration, reducing the precision requirements compared to a fully monolithic design.

Inventive Principle:
Principle #1Segmentation
