Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single vacuum pump and simple valve system is used, then the device structure is simple and manufacturing cost is low, but the device cannot adapt to different body parts and user types
Solution Approach 1:
The vacuum system is segmented into multiple independent vacuum pumps (first vacuum pump and second vacuum pump), each capable of operating independently or together. This segmentation allows different vacuum levels to be applied to different body parts simultaneously, enabling adaptation to various massage needs without requiring a completely complex system redesign.
Solution Approach 2:
The patent employs dynamic control through multiple solenoid valves (first solenoid valve, second solenoid valve, third solenoid valve) that can be activated in different combinations and sequences. This dynamic valve control system allows real-time adjustment of vacuum flow rates and pressure levels, enabling the device to adapt to different body parts and user requirements while maintaining a relatively simple base structure.
2Adaptability or versatility
If multiple vacuum pumps and solenoid valves are added to achieve different massage modes, then adaptability improves, but manufacturing cost increases
Solution Approach 1:
The multiple vacuum pumps and solenoid valves are designed with universal functionality, where the first vacuum pump and second vacuum pump can each independently perform complete massage cycles, and the solenoid valves serve multiple purposes (controlling vacuum application, release, and flow rate adjustment). This multi-functionality reduces the need for specialized components for each massage mode, thereby controlling manufacturing costs while achieving versatility.
Solution Approach 2:
The system achieves different massage modes by changing operational parameters (vacuum flow rates, pressure levels, timing sequences) rather than requiring fundamentally different hardware configurations. The solenoid valves adjust gas flow rates to create different negative pressure conditions, allowing one set of components to deliver multiple massage effects, thus avoiding the need for expensive specialized equipment for each mode.
3Ease of operation
If simple pumping or exhausting function is provided, then device complexity is low, but it causes troubles in operation for different body parts
Solution Approach 1:
The control board automatically manages the complex coordination of multiple vacuum pumps and solenoid valves based on pre-programmed sequences and user-selected modes. The system performs self-service by autonomously adjusting vacuum levels, flow rates, and timing without requiring manual intervention for each parameter change, thereby maintaining ease of operation despite the underlying system complexity.
Solution Approach 2:
The system incorporates feedback mechanisms where the control board monitors the operational state of vacuum pumps and solenoid valves, and automatically adjusts parameters to maintain optimal massage conditions for different body parts. This feedback control ensures consistent performance across various massage modes without requiring complex manual operation from the user.
