Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated communication devices are installed as access points for wireless networks, then communication infrastructure is provided, but cost and space requirements increase
Solution Approach 1:
The patent applies multi-functionality by enabling light sources to perform both their primary function of illumination and a secondary function of serving as wireless communication access points. The light source includes both light-emitting components and communication components (antenna, processor) that work together, allowing a single device to provide both lighting and network connectivity, thereby eliminating the need for separate dedicated communication devices
Solution Approach 2:
The patent merges the illumination function and communication function into a single integrated device. The light source system combines the light-emitting diodes (LEDs) with wireless communication components including antenna and processing units, creating a unified access point that delivers both lighting and network services simultaneously
2Reliability
If dedicated communication devices are installed as access points, then wireless network coverage is achieved, but installation and maintenance costs increase
Solution Approach 1:
The light source is designed with dual functionality as an illumination device and wireless access point, allowing existing lighting infrastructure to be leveraged for communication purposes. This eliminates the need to deploy separate communication devices, thereby reducing installation and maintenance costs while maintaining network coverage
