Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional wireless infrastructure is used to provide broadband access, then existing coverage areas are maintained, but bandwidth capability is insufficient to address increased demand
Solution Approach 1:
The patent divides the wireless communication infrastructure into macrocells for broad coverage and small cells (microcells and picocells) for high-bandwidth localized areas. This segmentation allows the system to simultaneously maintain extensive coverage while providing high bandwidth capability in specific regions where demand is highest.
2Ease of operation
If electrical return paths are used in transmission systems, then signal transmission is enabled, but system complexity and installation requirements increase
Solution Approach 1:
The patent extracts the electrical return path requirement from the transmission system by utilizing the earth or ground as the return path. This allows signal transmission to occur without requiring a separate dedicated return conductor, thereby simplifying the system structure and reducing installation complexity while maintaining electrical completeness.
3Length of stationary object
If conventional transmission media are used, then signal propagation is achieved, but propagation losses increase over distance
Solution Approach 1:
The patent changes the electrical parameters of the transmission medium by adjusting the impedance characteristics and utilizing resonant frequencies. By operating at resonant frequencies and optimizing impedance matching, the system achieves reduced propagation losses and extended transmission distances without requiring additional amplification or repeaters.
