Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gear selector switches or multi-gear toggle switches are used for speed control, then limited speed positions can be achieved, but the product structure becomes complex and operation becomes non-intuitive
Solution Approach 1:
The patent replaces mechanical gear selector switches with a touch-sensitive operating unit that directly controls motor speed through capacitive sensing. The detection module senses touch position and intensity to continuously vary motor speed without mechanical gears, eliminating the need for complex gear position detection ports and simplifying the overall control structure while enabling continuous speed variation.
Solution Approach 2:
The patent introduces an operating unit with detection module as an intermediary between user input and motor control. This intermediary translates touch gestures into speed control commands, providing intuitive operation while the control module processes the signals to achieve continuous speed variation without requiring complex mechanical gear systems.
2Adaptability or versatility
If multiple control ports and detection ports are added to match gear positions, then more speed positions can be controlled, but the product structure becomes more complex
Solution Approach 1:
The operating unit serves multiple functions: it detects touch position to determine speed level, detects touch intensity to determine acceleration, and provides intuitive user interaction. This single multi-functional component replaces what would otherwise require multiple separate control ports and detection ports for each gear position, simplifying the product structure while enabling continuous speed variation.
Solution Approach 2:
The patent merges the control and detection functions into a single integrated operating unit with a detection module. Instead of having separate control ports and detection ports for each gear position, the system combines these functions into one touch-sensitive interface that continuously varies speed based on touch parameters, reducing the number of components and simplifying the product structure.
3Productivity
If fixed speed control is used, then the product structure remains simple, but the lift performance cannot be fully optimized for high acceleration scenarios
Solution Approach 1:
The patent implements dynamic speed control where the motor speed is not fixed but continuously adjustable based on real-time detection of user touch gestures. The system adapts the speed profile during operation, enabling high acceleration upon actuation and continuous speed variation to optimize lift performance for different scenarios, transitioning from static fixed-speed control to dynamic variable-speed control.
Solution Approach 2:
The detection module provides real-time feedback on user touch input, and the control module uses this feedback to continuously adjust motor speed. This feedback loop enables the system to respond to user intentions and optimize acceleration performance dynamically, allowing the lift to achieve maximum exploitation of performance potential while maintaining a relatively simple structure through electronic rather than mechanical feedback.

AI summary
Disclosed are a speed-variable control arrangement, an electric lift mechanism, and an electric massaging mechanism. The speed-variable control arrangement includes an information processing module, an operation detecting module electrically connected to the operating unit, and a motor control module electrically connected to the motor, the operation detecting module and the motor control module being electrically connected to the information processing module; the operation detecting module detects an action variation quantity of the operating unit and transmits the detection result to the information processing module; the information processing module obtains a corresponding motor speed variation quantity based on the detection result and transmits the obtained motor speed variation quantity to the motor control module; and the motor control module changes the motor speed based on the motor speed variation quantity. As such, Speed control becomes more intuitive. As the speed control is not restricted by limited gear positions, continuous speed variation is achieved. Further, due to elimination of a speed selector switch that would require matched control and detection ports, the product structure is simplified.
