Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a charging cradle is used for wireless charging, then the charging process is simple and stable, but the charging distance is limited to short range only
Solution Approach 1:
The patent replaces the mechanical contact-based charging cradle system with a wireless electromagnetic field-based charging system. The transmitting device uses electromagnetic fields to transmit power wirelessly to the mobile terminal, eliminating the need for physical cradle contact and enabling long-range charging without mechanical constraints.
Solution Approach 2:
The patent introduces a management device as an intermediary that coordinates between the transmitting device and the mobile terminal. This management device receives location information from both parties, calculates optimal charging parameters, and controls the transmitting device to maintain appropriate electromagnetic field orientation and intensity, enabling stable long-range wireless charging.
2Adaptability or versatility
If wireless charging transmitters are controlled to send energy waves in specific directions, then directional and long-range charging is achieved, but the control system becomes more complex
Solution Approach 1:
The patent implements a feedback mechanism where the management device continuously receives location information from both the transmitting device and the mobile terminal, calculates the optimal transmitting direction based on their relative positions, and adjusts the electromagnetic field orientation accordingly. This closed-loop control enables adaptive directional charging while managing system complexity through intelligent algorithms.
Solution Approach 2:
The management device serves multiple functions: it acts as a coordinator between devices, a calculator for optimal charging parameters, a controller for the transmitting device, and a locator for tracking positions. By consolidating these diverse functions into a single multi-functional management device, the system achieves directional charging capability without proportionally increasing overall system complexity.
3Productivity
If location information is used to control wireless charging transmitters, then real-time and directional charging is enabled, but the requirement for information processing increases
Solution Approach 1:
The management device performs preliminary calculations of the optimal transmitting direction and charging parameters based on received location information before actual power transmission begins. By pre-processing the location data and determining charging parameters in advance, the system enables real-time responsive charging while reducing the computational burden during the actual power transmission phase.
