Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional charging infrastructure is used, then vehicle charging is simple, but operational autonomy is limited and charging efficiency is low
Solution Approach 1:
The vehicle is equipped with multiple charging interfaces including wireless charging coils, conductive charging terminals, and kinetic energy recovery systems that can operate with different charging infrastructures (stationary chargers, dynamic road charging, aerial charging), allowing the vehicle to adapt to various charging environments and methods simultaneously
Solution Approach 2:
The vehicle incorporates a dynamic charging system that can switch between different charging modes (stationary, dynamic, kinetic) based on operational conditions, with controllable connections that adjust engagement states real-time to optimize charging efficiency while managing system complexity
2Productivity
If conventional design limitations are maintained, then manufacturing is simple, but charging efficiency and operational performance are reduced
Solution Approach 1:
The charging system is divided into separate functional modules including wireless charging coils, conductive terminals, kinetic energy recovery devices, and control systems that can be manufactured independently and assembled, improving charging efficiency while managing manufacturing complexity through modular construction
Solution Approach 2:
The vehicle incorporates adjustable parameters such as controllable connection engagement states, variable charging rates, and adaptive kinetic energy recovery thresholds that optimize charging efficiency for different operational conditions without requiring complete redesign of the manufacturing process
3Use of energy by moving object
If charging connections are continuously engaged, then charging is maximized, but wear and reliability issues increase
Solution Approach 1:
The charging connection system implements periodic engagement and disengagement cycles rather than continuous connection, with the controller managing connection states to optimize energy transfer while reducing mechanical wear and electrical contact degradation, thereby maintaining reliability
Solution Approach 2:
The system incorporates sensors and controllers that monitor connection status, wear levels, and charging efficiency, providing feedback to adjust engagement timing and duration, maximizing energy transfer while preventing excessive wear that would compromise connection reliability

AI summary
Methods, devices, and systems are provided to shield a passenger compartment of an electric vehicle from electromagnetic fields present during a wireless charging process. A charging system may include a power source and a charging plate wirelessly coupled to the power source, where the power source wirelessly transfers power to the charging plate. The system may further include at least one shield portion between the charging plate and a passenger compartment of the electric vehicle, where the at least one shield portion is configured to attenuate an electromagnetic field provided by the charging system.
