Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional indoor radio solutions are implemented, then indoor radio coverage is achieved, but installation becomes invasive requiring multiple ceiling holes and restoration work
Solution Approach 1:
The patent combines the radio transceiver functionality with the LED lighting fixture into a single integrated unit. The radio transceiver is housed within the LED fixture housing, eliminating the need for separate ceiling installations. This merging of functions allows the same infrastructure to serve both lighting and radio coverage purposes without requiring additional invasive installation.
Solution Approach 2:
The LED lighting fixture is designed to perform multiple functions: providing illumination and housing a radio transceiver for indoor coverage. This multi-functionality allows existing lighting infrastructure to be repurposed for radio deployment, eliminating the need for dedicated radio installation infrastructure and reducing installation invasiveness.
2Reliability
If distributed antenna systems (DAS) are deployed, then indoor coverage is improved, but system cost increases due to requiring two complete radio infrastructures
Solution Approach 1:
The LED lighting fixture serves dual purposes as both a lighting device and a radio transceiver housing. This eliminates the need for separate DAS infrastructure by repurposing existing lighting fixtures, thereby reducing system cost while maintaining indoor coverage capability.
Solution Approach 2:
The existing LED lighting infrastructure is repurposed to provide radio coverage functionality. By utilizing already-installed lighting fixtures, the system eliminates the need for additional dedicated infrastructure, reducing overall system cost while maintaining coverage reliability.
3Reliability
If active radio heads are installed in ceilings, then radio signal distribution is achieved, but installation time and restoration costs increase
Solution Approach 1:
The radio transceiver is integrated within the LED fixture housing, combining two installation processes into one. The same mounting procedure that installs the LED fixture also positions the radio transceiver, eliminating the need for separate ceiling penetration and installation steps, thereby reducing installation time and restoration requirements.
4Ease of operation
If TV/Cable wall outlets are repurposed for radio applications, then installation complexity is reduced, but radio deployment locations become suboptimal
Solution Approach 1:
The LED lighting fixtures, which are optimally positioned for both lighting and radio coverage, are repurposed to house radio transceivers. This eliminates the need to use suboptimal TV/Cable outlet locations, maintaining radio deployment optimization while keeping installation simple by utilizing existing lighting infrastructure.
