Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple outlets are provided to power multiple devices simultaneously, then the power availability is improved, but the device complexity and installation requirements increase
Solution Approach 1:
Multiple power pads are interconnected through edge connectors to form a unified power distribution network, allowing a single power source to serve multiple devices simultaneously. The pads merge their power delivery capabilities through the connector interface, eliminating the need for multiple separate outlets.
Solution Approach 2:
Each power pad is designed with universal connectors on its edges that can mate with adjacent pads, enabling the same pad design to function both as a standalone power source and as part of an extended power network. This multi-functionality allows flexible configuration without requiring different hardware for single vs. multiple device scenarios.
2Adaptability or versatility
If power pads are interconnected to form various shapes, then the adaptability is improved, but the connector complexity increases
Solution Approach 1:
The power distribution system is segmented into modular pads, each with standardized edge connectors. This segmentation allows the system to be configured in various shapes and sizes by simply arranging and connecting identical modular units, achieving high adaptability without increasing individual component complexity.
Solution Approach 2:
Connectors are placed specifically at the edges of each pad, concentrating the connection functionality at localized interface points. This local placement of connectors simplifies the overall design by confining complexity to standardized edge interfaces rather than requiring complex internal routing throughout the entire power network.
3Ease of operation
If power is transmitted through embedded coils, then the ease of operation is improved, but the energy efficiency decreases
Solution Approach 1:
The system performs preliminary detection to verify proper alignment and coupling between transmitter and receiver coils before initiating full power transmission. This preliminary action ensures optimal inductive coupling, maximizing power transfer efficiency and minimizing energy losses from misalignment or poor coupling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution allows for efficient and flexible power distribution among multiple devices without the need for multiple outlets, enabling simultaneous charging of devices in various configurations, such as polygonal, circular, or arc-shaped layouts, by using embedded power coils and connectors that transfer power between pads.
Implementation Method 1
Inductive proximity power pads utilize a transmitter coil to provide power to one or more devices having receiver coils. Power is transmitted from the transmitter coil to the receiver coil when the device is placed in proximity to the transmitter coil on or about the power pad.
