Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wired power management is used, then power supply is reliable, but wire clutter increases and adaptability decreases
Solution Approach 1:
The patent replaces the mechanical wired power connection system with a wireless power transmission system using electromagnetic fields. The control box includes a wireless communication module that transmits power signals wirelessly to peripheral components, eliminating the need for physical wire connections and reducing wire clutter while maintaining power supply functionality.
Solution Approach 2:
The control box is designed with multi-functional capabilities, integrating both control signal processing and wireless power transmission functions. This universal design allows the same device to handle both data communication and power delivery, expanding compatibility with various peripheral components while reducing the need for separate power management hardware.
2Reliability
If mains power is used, then power supply is continuous, but operation fails during power outages
Solution Approach 1:
The patent implements a battery backup system that is pre-charged during normal operation when mains power is available. The battery is automatically charged through the power supply circuit, storing energy in advance so that it can immediately take over and maintain continuous operation when a power outage occurs, ensuring uninterrupted bed adjustment functionality.
Solution Approach 2:
The power management system incorporates a buffer mechanism using a capacitor or small battery that provides immediate power cushioning during the transition from mains power to backup power. This beforehand cushioning ensures there is no interruption in power supply to critical components during power outages, maintaining system reliability.
3Adaptability or versatility
If multiple voltage levels are provided, then compatibility with peripherals improves, but power management complexity increases
Solution Approach 1:
The patent employs a DC-DC converter module that can dynamically change output voltage parameters based on the requirements of connected peripheral devices. The converter adjusts its output voltage level automatically, providing different voltage outputs (e.g., 5V, 12V, 24V) as needed, which enables compatibility with various peripherals while keeping the power supply architecture relatively simple through parameter adjustment rather than multiple fixed voltage sources.
