Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual charging initiation and location selection is used, then the operator has full control over charging decisions, but the charging process becomes time-consuming and requires purposeful travel to charging stations
Solution Approach 1:
The system enables autonomous charging initiation through automatic vehicle detection, authentication, and charging session management without requiring operator intervention. The controller automatically detects when a vehicle is positioned on the charging platform, authenticates it, and initiates the charging process, eliminating the need for manual operation and reducing time loss.
Solution Approach 2:
The system performs preliminary actions by pre-positioning the charging platform, pre-authenticating vehicles through RFID or other identification systems, and pre-configuring charging parameters before the vehicle arrives. This allows the charging process to begin immediately upon vehicle positioning, eliminating setup time and reducing overall charging time.
2Duration of action of moving object
If the vehicle is operated until battery depletion to maximize usage time, then the discharge cycle is optimized, but the vehicle remains immobile for long periods during recharging
Solution Approach 1:
The system enables continuous charging by allowing the vehicle to remain on the charging platform throughout the entire charging process without interruption. The automated system maintains continuous power transfer from the charging platform to the vehicle battery, eliminating idle time and keeping the vehicle in a useful state (parked and charged) rather than immobile and uncharged.
Solution Approach 2:
The system implements periodic charging sessions where the vehicle automatically returns to the charging platform at scheduled intervals or when battery charge drops below a threshold. This periodic action optimizes the discharge cycle while minimizing total immobilization time by efficiently utilizing charging opportunities.
3Quantity of substance
If full battery recharging is performed in one continuous session, then the battery capacity is maximized, but the charging process is time-consuming and inefficient
Solution Approach 1:
The charging inductive coil is divided into multiple independently controllable segments that can be selectively activated. The system segments the charging process into multiple phases or zones, allowing different portions of the battery to be charged at different rates or times, thereby maximizing overall charging efficiency while still achieving full battery capacity.
Solution Approach 2:
The system dynamically adjusts charging parameters including power delivery rate, active coil segments, and charging duration based on real-time battery state, vehicle requirements, and grid conditions. This dynamic optimization enables faster charging when conditions permit while maintaining safety and efficiency, thereby increasing productivity without sacrificing charge capacity.
4Device complexity
If the charging inductive coil uses a fixed configuration, then the system structure is simple, but energy transfer efficiency decreases when vehicle positioning is not optimal
Solution Approach 1:
The charging inductive coil is divided into multiple independently controllable segments arranged in specific patterns. The system can selectively activate different segments based on vehicle position and size, creating optimized magnetic coupling zones that maximize energy transfer efficiency while maintaining a relatively simple overall structure.
Solution Approach 2:
The system dynamically reconfigures the active coil segments and their excitation patterns based on real-time vehicle detection, positioning, and charging requirements. This dynamic adaptation optimizes the magnetic field distribution to match the vehicle's receiving coil position, minimizing energy loss without requiring a complex fixed configuration for every possible scenario.
