Innovation Solution
A laminated member with an inductively coupled receiver coil integrated within the door's stile or rail, allowing for seamless energy transfer between the door and frame, hidden from view and protected from mechanical stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are placed in an articulating arm to transfer electrical energy, then continuous power transmission is achieved, but mechanical complexity increases and visual appearance deteriorates
Solution Approach 1:
The patent replaces the mechanical wire transmission system with an inductive energy transfer system using electromagnetic fields. The transmitter coil in the door frame and receiver coil in the door panel enable wireless energy transfer, eliminating the need for articulating arms and visible wires, thus reducing mechanical complexity while maintaining continuous power transmission reliability
2Reliability
If wires are passed through hinge openings to transfer electrical energy, then continuous power transmission is achieved, but mechanical complexity increases and visual appearance deteriorates
Solution Approach 1:
The patent eliminates the mechanical wire routing through hinges by implementing inductive coupling between a transmitter coil in the door frame and a receiver coil embedded in the door panel. This wireless energy transfer method removes the need for hinge openings and wire management, reducing mechanical complexity while ensuring continuous power transmission
3Area of moving object
If narrow edge space is used for wires, then space utilization is improved, but reliability deteriorates due to limited space for wire management
Solution Approach 1:
The patent replaces the wire-based electrical connection system with an inductive energy transfer system. The receiver coil is embedded within the door panel structure, eliminating the need for narrow edge wire routing and associated management challenges, thus improving reliability while maintaining efficient space utilization
4Ease of manufacture
If visible wires are used for energy transfer, then ease of installation is improved, but visual appearance deteriorates
Solution Approach 1:
The patent replaces visible wire installations with an inductive energy transfer system using electromagnetic fields. The transmitter and receiver coils are integrated into the door frame and panel respectively, enabling wireless energy transfer that eliminates visible wires, thus improving visual appearance while maintaining ease of installation through standardized coil components
