Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of switches and buttons is increased to control multiple movable components, then the control capability is improved, but the operation becomes cumbersome and uncomfortable
Solution Approach 1:
The patent replaces traditional mechanical switches and buttons with a sensor-based detection system. The sensor detects the spatial position and motion state of the remote control device, automatically generating control signals without requiring physical button presses for each control function. This substitution reduces mechanical complexity while maintaining comprehensive control capability over multiple movable components.
Solution Approach 2:
The remote control device is designed with universal functionality where a single sensor system can detect various types of input (position, motion, orientation) and control multiple different movable components (table top, head section, leg section) through unified spatial detection, eliminating the need for separate switches for each component.
2Device complexity
If traditional switches and buttons are used, then the control mechanism is simple, but intuitive operation and speed adjustment are not provided
Solution Approach 1:
The patent replaces simple mechanical switches with an accelerometer-based detection system that automatically senses motion state and spatial position. This system provides intuitive control by detecting the natural motion of the remote control device in space, eliminating the need for users to learn complex switch combinations while maintaining relatively simple device architecture.
Solution Approach 2:
The patent changes the control parameter from discrete switch states to continuous spatial position and motion acceleration values. By detecting acceleration in different directions and spatial coordinates, the system enables intuitive speed adjustment and directional control, where the magnitude and direction of remote control motion directly correspond to the desired motion parameters of the medical apparatus components.
3Measurement precision
If multiple buttons and soft keys are added to control different directions and speeds, then the control precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces multiple physical buttons and soft keys with a sensor-based detection system that uses accelerometer data and spatial position information to determine control parameters. The sensor automatically calculates motion direction, speed, and acceleration based on detected acceleration values, providing precise control without requiring multiple separate control elements.
Solution Approach 2:
A single sensor system performs multiple control functions simultaneously by analyzing different aspects of the detected acceleration and position data. The same sensor input can control direction, speed, and acceleration of movable components, eliminating the need for separate buttons for each control parameter while maintaining high control precision.
