Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication devices are deployed in environments without electrical power, then wireless communication coverage is improved, but the devices cannot operate without power sources
Solution Approach 1:
The patent combines power transmission and data transmission into a single optical wireless communication system. The optical transceiver simultaneously transmits both power and data through optical signals, eliminating the need for separate power cables and enabling deployment in locations without electrical outlets.
Solution Approach 2:
The optical transceiver performs multiple functions: it transmits power wirelessly, transmits data wirelessly, and provides network gateway functionality. This multi-functional device replaces traditional separate power sources and communication devices, enabling autonomous operation without wall power.
2Use of energy by moving object
If power cables are laid within walls or structures, then electrical power is provided to devices, but construction work is required and installation time increases
Solution Approach 1:
The patent replaces the mechanical system of physical power cable installation with an optical wireless power transmission system. Instead of laying cables through walls and structures, the system uses optical transceivers to beam power wirelessly through air, eliminating construction work and reducing installation time to simple device placement.
3Use of energy by moving object
If power cables are laid outside walls, then electrical power is provided to devices, but the design aesthetic is compromised
Solution Approach 1:
The patent eliminates visible external power cables by substituting the electrical cable system with an optical wireless power transmission system. Power is delivered invisibly through optical beams, maintaining clean aesthetics while providing power to devices placed anywhere within the optical coverage area.
4Ease of operation
If traditional wireless routers are used without wall power, then portability is improved, but they cannot provide sustained operation without cable power
Solution Approach 1:
The patent merges power reception and data communication functions into a single optical wireless system. The autonomous optical wireless hotspot receives both power and data through optical transceivers, enabling sustained operation without cable power while maintaining portability and ease of deployment.
