Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual plugging and unplugging of power source plugs is used, then power can be supplied to electrical equipment on the medical bed, but frequent manual operations are inconvenient and inefficient
Solution Approach 1:
The system automatically establishes electrical connection when the medical bed moves to the target position. The bed body is equipped with a power receiving device that automatically docks with the power transmitting device at the target position, eliminating the need for manual plugging operations. The system serves itself by detecting position and automatically connecting power.
Solution Approach 2:
The patent replaces the mechanical plug-and-socket system with an automatic electrical connection system. Instead of manually connecting physical plugs, the system uses electromagnetic coupling between transmitting and receiving devices to establish power connection automatically based on position detection.
2Adaptability or versatility
If the medical bed moves between multiple positions, then patient transport convenience is improved, but frequent manual power connection operations increase workload
Solution Approach 1:
The system automatically manages power connection based on the bed's movement state. When the bed arrives at a target position, the power receiving device automatically docks with the power transmitting device without requiring manual intervention. The system monitors position and autonomously establishes or breaks electrical connections as needed.
Solution Approach 2:
The system prepares power connection in advance by positioning the power receiving device on the bed body to align with target position power transmitting devices. Before the bed actually reaches the target position, the connection mechanism is ready to engage immediately upon arrival, ensuring seamless power supply.
3Ease of operation
If automatic power connection is implemented, then operational convenience is improved, but electromagnetic interference may increase
Solution Approach 1:
The patent acknowledges electromagnetic interference as an inherent issue with automatic power transmission but converts it into a manageable parameter through shielding measures. The system uses electromagnetic shielding materials and structures to contain and control the interference, transforming a harmful effect into a controlled aspect of the design.
Solution Approach 2:
The system introduces electromagnetic shielding as an intermediary element between the power transmitting and receiving devices. This shielding layer acts as a mediator that allows power transmission while filtering and reducing harmful electromagnetic interference, protecting sensitive medical equipment from interference.
