Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing negative pressure massage devices lack the ability to adjust pressure, making it difficult to optimally adapt to different parts of the human body and various massage targets, such as the elderly and children, leading to operational troubles and increased manufacturing costs.
Innovation Solution
The negative pressure massage device incorporates a vacuum pump and a system of solenoid valves controlled by a board, allowing for adjustable pressure settings by controlling the flow through the valves, thereby accommodating different body parts and massage targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If general negative pressure massage equipment is used without pressure adjustment function, then the device structure is simple and manufacturing cost is low, but it cannot optimally adapt to different parts of the human body and different massage targets
Solution Approach 1:
The patent implements dynamic pressure adjustment capability by incorporating a pressure adjustment mechanism that allows the negative pressure level to be changed during operation. This enables the same device to adapt to different body parts and massage targets by dynamically modifying the pressure parameters rather than requiring multiple fixed devices.
Solution Approach 2:
The patent changes the pressure parameter as a variable control mechanism. By allowing the negative pressure value to be adjusted within a range (e.g., 0-80 mmHg), the device can optimize its performance for different massage scenarios such as facial massage, body massage, or use on different age groups, thereby achieving versatility through parameter variation.
2Adaptability or versatility
If multiple sets of equipment are manufactured to adapt to different body parts and targets, then optimal adaptation is achieved, but manufacturing cost increases
Solution Approach 1:
The patent designs a universal negative pressure massage device that can perform multiple functions by adjusting pressure levels. Instead of manufacturing separate devices for different body parts or age groups, a single device with pressure adjustment capability serves all purposes, from gentle facial massage to more intensive body massage, thereby reducing overall manufacturing costs.
Solution Approach 2:
By making the pressure parameter adjustable rather than fixed, the device achieves multi-functionality without requiring multiple physical units. This parameter-based versatility allows one device to replace what would traditionally require several specialized devices, significantly reducing manufacturing expenses.
3Adaptability or versatility
If pressure adjustment function is added to negative pressure massage device, then adaptability to different body parts and targets is improved, but operational complexity increases
Solution Approach 1:
The patent incorporates automatic pressure control mechanisms that can self-regulate the negative pressure levels based on pre-set parameters or sensor feedback. This reduces the need for manual intervention and complex user control, allowing the device to automatically adapt to different massage scenarios while maintaining ease of operation.
Solution Approach 2:
The patent may incorporate feedback mechanisms that monitor pressure levels and automatically adjust them to optimal values for different body parts and massage targets. This closed-loop control simplifies operation by eliminating the need for users to manually tune pressure settings, while still achieving high adaptability through automated parameter optimization.

AI summary
A negative pressure massage device includes: a vacuum pump communicating to an open end; a first solenoid valve communicating to the vacuum pump and the open end; a second solenoid valve communicating to the vacuum pump, the open end, and the first solenoid valve; a third solenoid valve communicating to the vacuum pump, the open end, the first solenoid valve, and the second solenoid valve; and a control board electrically connected to the vacuum pump, the first solenoid valve, the second solenoid valve, and the third solenoid valve. When any one of the first solenoid valve, the second solenoid valve, and the third solenoid valve is opened, the vacuum pump maintains communicating with the open end.
