Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless communication devices are deployed in spaces without electrical power, then coverage area is expanded, but device power availability deteriorates
Solution Approach 1:
The patent replaces the traditional electrical power delivery system (wires/cables) with an optical wireless power transmission system using laser beams. This allows power to be transmitted through free space without physical connections, enabling devices to operate in locations without electrical outlets while maintaining power availability.
Solution Approach 2:
The patent combines power transmission and data communication into a single optical wireless system. The same optical infrastructure transmits both electrical energy (for power) and information (for data), eliminating the need for separate power and communication systems and enabling deployment in previously inaccessible locations.
2Use of energy by moving object
If cable-based power delivery is used, then power availability is ensured, but installation complexity and construction requirements increase
Solution Approach 1:
The patent substitutes the mechanical cable-based power delivery system with a wireless optical transmission system. This eliminates the need for physical cable installation, drilling, and electrical connections, dramatically reducing installation complexity while maintaining reliable power delivery to devices.
3Ease of operation
If radiofrequency bandwidth is used for wireless communication, then wireless data transmission is achieved, but bandwidth limitations and interference increase
Solution Approach 1:
The patent transitions from radiofrequency electromagnetic waves to optical frequency electromagnetic waves for wireless communication. This parameter change in the carrier wave frequency provides vastly greater available bandwidth, enabling high-speed data transmission without the bandwidth limitations and interference problems associated with traditional radiofrequency systems.
