Solution Overview

Problem

Existing healthcare tools with piston-type blowing and sucking structures suffer from low intensity and complex coordination, resulting in inadequate air blowing and sucking forces.

Innovation Solution

A motor-linked blowing and sucking structure featuring a cavity tube with a swinging vane and linkage, where the drive motor rotates to induce a fan-shaped reciprocating motion of the vane, enhancing transmission ratio and torque for increased air pressure adjustment and effect.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a piston type blowing and sucking structure is used, then the structure can achieve air blowing and sucking function, but the structure becomes complex and the blowing and sucking intensity becomes low

Engineering Contradiction:

Improveblowing and sucking intensityVSAvoidstructure complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the piston component from the traditional piston-type blowing and sucking structure, replacing it with a swinging vane that moves within a cavity tube. This extraction simplifies the overall structure by eliminating the need for complex piston coordination mechanisms while maintaining the air blowing and sucking function through the swinging vane's reciprocating motion within the sealed cavity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a piston that moves linearly within a cylinder, the patent inverts the approach by using a swinging vane that rotates within a cavity tube. The linkage converts rotational motion from the drive motor into the swinging vane's reciprocating motion, fundamentally changing the motion mechanism from linear piston movement to rotational vane swinging, thereby simplifying the structure and improving intensity.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If a piston type blowing and sucking structure is used, then the structure can achieve air blowing and sucking function, but the structure becomes complex with difficult coordination between components

Engineering Contradiction:

Improvecoordination complexityVSAvoidcomponent coordination

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple components into a more integrated system. The linkage directly connects the drive motor to the swinging vane, eliminating the need for separate piston coordination mechanisms. The swinging vane itself performs both the sealing function (through its side wall fitting into the cavity tube inner wall) and the air displacement function, reducing the number of separate components and their coordination requirements.

Inventive Principle:

Principle #5Merging (Combining)

3Volume of moving object

If the same spatial structure is used, then the device size is constrained, but the amplitude of motion is limited

Engineering Contradiction:

Improvespatial structure sizeVSAvoidamplitude of motion

Core Design Contradiction:

Volume of moving objectVSLength of moving object

Solution Approach 1:

The patent employs dynamic motion of the swinging vane within the fixed cavity tube. The linkage converts the drive motor's rotational motion into the swinging vane's reciprocating motion, allowing the vane to dynamically change its position and orientation within the cavity. This dynamic approach enables larger amplitude of motion (the vane swings through a fan-shaped arc) without increasing the overall device volume, as the motion occurs within the existing spatial constraints of the cavity tube.

Inventive Principle:

Principle #15Dynamics

AI summary

A motor-linked blowing and sucking structure and a health care tool using the same, the motor-linked blowing and sucking structure including a cavity tube and a linkage. A swinging vane is disposed in the cavity tube, and a side wall of the swinging vane fits into an inner wall of the cavity tube; one end of the linkage is connected to a drive motor and the other end of the linkage is connected to the swinging vane; the drive motor rotates to drive the linkage; and the linkage as an engagement structure allows a fan-shaped reciprocating motion of the swinging vane within the cavity tube to achieve a higher transmission ratio and a larger torque, such that a larger amplitude of motion can be achieved with the same spatial structure, achieving a more significant air blowing and sucking effect at an opening of the cavity tube.
