Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If cords are laid across the surface to power electronic devices, then power supply is achieved, but the amount of surface space available for other activities decreases
Solution Approach 1:
The patent extracts the power supply function from traditional cord-based connections and relocates it into the surface structure itself through embedded power nodes and wireless charging pads. This removes cords from the surface area, freeing up space while maintaining power supply capability through integrated charging infrastructure.
Solution Approach 2:
The patent replaces the mechanical cord connection system with wireless electromagnetic field-based power transmission. By using electromagnetic induction through embedded coils and wireless charging pads, the system eliminates the need for physical cord connections, thereby removing the space occupation issue while preserving power delivery.
2Area of stationary object
If wireless charging pads are added to provide wireless charging, then surface space is maintained, but device complexity increases
Solution Approach 1:
The patent implements power nodes that serve multiple functions: they provide power for wireless charging, illuminate to indicate charging status, and can be configured in modular arrangements. This multi-functionality reduces the need for separate components, thereby managing complexity while maintaining surface space.
Solution Approach 2:
The patent divides the power supply system into modular power nodes that can be independently configured and arranged in grids or patterns. Each node is a self-contained unit with standardized interfaces, allowing flexible system design without proportionally increasing overall complexity. The modular approach enables scalable implementation.
3Adaptability or versatility
If multiple layers are integrated to accommodate power supply and lighting, then functionality is improved, but manufacturing complexity increases
Solution Approach 1:
The patent transitions from planar surface design to a multi-layer three-dimensional structure. Power nodes, lighting elements, and wireless charging pads are distributed across multiple layers (first layer with power nodes, second layer with lighting, third layer with wireless charging). This vertical stacking enables enhanced functionality while maintaining manufacturability through standardized layer assembly.
Solution Approach 2:
The patent implements a nested layer structure where the second layer with lighting elements is positioned between the first layer (power nodes) and the third layer (wireless charging pads). Each layer is self-contained and can be manufactured separately, then assembled together, reducing overall manufacturing complexity despite the multi-functional design.
4Reliability
If power nodes are distributed across the surface, then power availability is improved, but device complexity increases
Solution Approach 1:
The patent segments the power supply system into multiple distributed power nodes arranged in grids or patterns across the surface. Each node is a modular unit with standardized power output and communication interfaces. This segmentation improves power availability through redundancy and distributed architecture while managing complexity through standardization and modularity.
Solution Approach 2:
The power nodes incorporate automatic configuration capabilities through Bluetooth or NFC communication, allowing them to self-organize and establish power delivery paths without manual intervention. This self-service feature reduces the operational complexity of managing distributed power nodes while maintaining high power availability.
