Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional charging stations are used, then charging infrastructure is provided, but they are not efficiently designed to handle multiple vehicles with varying sizes and types
Solution Approach 1:
The charging system is divided into modular components including a movable charging head that can service multiple parking spaces, individual vehicle communication modules, and segmented control functions. This segmentation allows the system to adapt to different vehicle sizes and types while maintaining manageable system complexity through standardized interfaces and modular architecture.
Solution Approach 2:
The charging head is designed to be movable rather than fixed, allowing it to dynamically reposition between parking spaces based on vehicle queue and charging needs. The system dynamically adjusts charging parameters based on real-time vehicle requirements, enabling versatile service across multiple vehicle types while simplifying the overall infrastructure through a single adaptable charging unit.
2Loss of energy
If existing systems are used, then charging capability is provided, but they do not optimize power transfer efficiency
Solution Approach 1:
The system implements bidirectional communication between the charging head and vehicle controllers, enabling real-time feedback on battery charge levels, power transfer efficiency, and vehicle requirements. This feedback loop allows the control module to dynamically optimize power transfer parameters, minimizing energy losses while maintaining high charging productivity through adaptive power delivery.
Solution Approach 2:
The charging system dynamically adjusts operational parameters including power delivery rate, voltage, and current based on real-time vehicle battery state and charging progress. By changing these parameters adaptively rather than using fixed settings, the system optimizes power transfer efficiency at each charging stage while maintaining high overall charging productivity.
3Ease of operation
If existing systems are used, then charging is provided, but they do not manage charge requests effectively
Solution Approach 1:
The system performs preliminary actions by pre-positioning the movable charging head in anticipation of vehicle arrivals, and by pre-negotiating charge requests with vehicles in the queue before the charging head becomes available. This preliminary coordination reduces waiting time and simplifies operation by eliminating delays during the actual charging process.
Solution Approach 2:
The charge request management system dynamically prioritizes and reorders vehicles in the queue based on real-time factors such as battery charge levels, vehicle type requirements, and predicted wait times. This dynamic reordering optimizes overall system efficiency and reduces average waiting time while providing clear, adaptive guidance to drivers, improving ease of operation.

AI summary
Parking infrastructure includes a charger disposed beneath parking spaces that provides charge to batteries for each of a plurality of vehicles, and a control module. The control module is configured to, in response to vehicle charge requests that includes routine data from each vehicle controller associated with each vehicle, connect the charger to each vehicle associated with each request based on a queue organized by a threshold sufficient to complete a routine from the routine data for each vehicle, and, in response to exceeding the threshold for each vehicle, check the queue for additional charge requests.
