Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If electromagnetic signal transmission power is boosted to maintain signal strength over distance, then received power is improved, but energy wastage increases significantly
Solution Approach 1:
The patent applies local quality by creating concentrated energy pockets at specific spatial locations where receivers are positioned. Instead of uniformly transmitting energy in all directions, the system locally concentrates electromagnetic energy at targeted positions through phase and amplitude control of multiple antenna elements, thereby improving received power at specific points while minimizing overall energy wastage.
Solution Approach 2:
The patent transitions from traditional omnidirectional or directional transmission to three-dimensional energy pocket formation. By utilizing spatial dimensionality and controlling electromagnetic fields in three-dimensional space through multiple antenna elements, the system creates localized energy concentrations at specific coordinates, enabling efficient power transfer without requiring excessive transmission power.
2Loss of energy
If directional power transmission is used to enhance transmission efficiency, then energy efficiency is improved, but device location knowledge and alignment requirements increase complexity
Solution Approach 1:
The patent implements self-service through automatic receiver detection and localization capabilities. The system autonomously identifies receiver positions using communication protocols, calculates optimal energy pocket locations, and adjusts antenna element phases and amplitudes automatically without requiring manual alignment or complex user intervention, thereby maintaining transmission efficiency while reducing operational complexity.
Solution Approach 2:
The patent employs feedback mechanisms where receivers communicate their positions and status to the transmitter system. This feedback enables the system to dynamically adjust energy pocket formation parameters, maintain optimal transmission efficiency, and adapt to changing receiver locations without increasing alignment complexity for end users.
3Device complexity
If single antenna reception is used, then device simplicity is maintained, but received power at large distances becomes insufficient
Solution Approach 1:
The patent applies segmentation by dividing the receiving function into multiple antenna elements arranged in arrays. Each antenna element contributes to forming energy pockets, and through coherent combining of signals from multiple elements, the system achieves enhanced received power at large distances while maintaining receiver integration within mobile devices.
