Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a pre-determined size system is used, then the system structure is simple and easy to manufacture, but the system lacks flexibility and cannot be extended to arbitrary sizes
Solution Approach 1:
The power transmitting system is divided into multiple identical transmitter modules, each containing one or more transmitter coils. These modules can be connected in different configurations to create power transmitting surfaces of arbitrary sizes, allowing the system to adapt to different application requirements while maintaining a standardized, manageable structure for each module.
Solution Approach 2:
Each transmitter module is designed with a universal structure that can function independently or be combined with other identical modules. The standardized design of each module allows it to serve multiple purposes - whether used alone or as part of a larger array - providing versatility in system configuration without requiring different designs for different sizes.
2Area of stationary object
If multiple predetermined size systems are put together, then the total coverage area increases, but gaps remain between systems and operation is not properly provided at border positions
Solution Approach 1:
The system is segmented into modular transmitter modules with standardized interfaces. Each module contains transmitter coils arranged to ensure that when modules are connected, the coil pattern continues seamlessly across module boundaries, eliminating gaps and ensuring continuous power transmission across the entire assembled surface.
Solution Approach 2:
Multiple transmitter modules are combined to form a unified power transmitting surface. The modules are designed to connect seamlessly, merging their individual coil patterns into a continuous, uninterrupted array that provides uniform power transmission across the entire assembled area without gaps or discontinuities at the interfaces.
3Adaptability or versatility
If the transmitter area size is fixed, then the manufacturing and deployment is straightforward, but the system cannot be extended or reconfigured for different applications
Solution Approach 1:
The transmitter system is segmented into standardized, identical modules that can be manufactured using the same processes. This segmentation allows for straightforward manufacturing of each module while enabling flexible assembly into larger configurations, combining manufacturing simplicity with system extendability.
Solution Approach 2:
The modular design allows smaller transmitter module configurations to be nested within or combined to form larger configurations. The same basic module unit can be used to create systems of various sizes by simply increasing the number of modules, providing a scalable approach that maintains manufacturing consistency while achieving different deployment scales.
