Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging systems use charging plates connected to mains by electric conductors, then contact-free electromagnetic induction charging is achieved, but the system remains place-related and requires wires within user reach
Solution Approach 1:
The patent extracts the charging functionality from traditional charging units and wall sockets, embedding power transmission elements directly into surfaces like floors and furniture. This removes the need for separate charging equipment and wired connections to mains, achieving complete wireless charging while eliminating charging unit complexity
Solution Approach 2:
The patent merges charging functionality with everyday surfaces such as floors, walls, and furniture. By integrating power transmission elements into these surfaces, the system combines multiple functions (surface utility + wireless power transmission) into unified structures, eliminating the need for separate charging plates and wired connections
2Productivity
If manual charging control is used with conventional charging units, then charging can be performed, but users face inconveniences including misplaced equipment, limited compatibility, and forgotten charging
Solution Approach 1:
The patent enables devices to charge automatically when placed on powered surfaces without user intervention. The system self-detects device presence, initiates charging, and manages power transfer autonomously, eliminating manual charging control requirements and associated inconveniences
Solution Approach 2:
The patent creates a universal charging infrastructure where any surface can provide wireless power to any compatible device. This multi-functional approach eliminates device-specific charging units and wall socket dependencies, allowing any terminal device to charge on any powered surface
3Ease of operation
If charging equipment is carried along by users, then charging mobility is improved, but the equipment becomes inconvenient to carry and adds weight
Solution Approach 1:
The patent extracts charging functionality from portable charging units and distributes it throughout the environment via powered surfaces. This eliminates the need to carry charging equipment, as power transmission capabilities are embedded in stationary surfaces like floors and furniture
4Duration of action of moving object
If frequent charging interruptions occur due to manual control, then battery may run down too soon, but automated continuous charging requires infrastructure changes
Solution Approach 1:
The patent enables continuous charging by keeping devices on powered surfaces throughout use. The infrastructure allows uninterrupted power transfer from the moment a device is placed on a surface, eliminating charging interruptions and ensuring constant battery availability without requiring complex portable charging solutions
