Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing negative pressure massaging devices have an inadequate suctioning effect, which fails to effectively relieve fatigue and soreness in the human body.
Innovation Solution
A negative pressure generator and massaging device that includes a chamber body with a suction nozzle, a piston arranged inside the chamber body, and a driving device to reciprocate the piston, generating negative pressure at the suction nozzle. The system incorporates a sealing ring and a unidirectional exhaust structure to enhance suction efficiency and reduce moving resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a piston is reciprocated inside a chamber body to generate negative pressure, then suctioning effect is improved, but moving resistance increases
Solution Approach 1:
The piston is segmented into multiple independent sealing units, each with its own sealing ring. This segmentation allows each sealing unit to independently adapt to the chamber wall, reducing overall friction while maintaining effective sealing across the entire piston surface, thus lowering moving resistance without compromising suctioning effect.
Solution Approach 2:
The sealing rings are made of flexible elastic materials that can deform to conform to the chamber wall surface. This flexibility creates an effective seal with minimal contact pressure, reducing friction and moving resistance while preventing air leakage that would reduce suctioning effectiveness.
2Reliability
If sealing performance is enhanced between piston and chamber body, then negative pressure generation is improved, but moving resistance increases
Solution Approach 1:
The sealing rings are made of flexible elastic materials that can deform to conform to the chamber wall surface. This flexibility creates an effective seal with minimal contact pressure, reducing friction and moving resistance while preventing air leakage that would reduce suctioning effectiveness.
Solution Approach 2:
The sealing rings are designed to be dynamically adaptable, deforming under pressure to maintain optimal contact with the chamber wall. This dynamic sealing mechanism ensures reliable sealing during reciprocation while minimizing friction through controlled deformation rather than rigid contact.
3Productivity
If piston reciprocation speed is increased to improve massaging efficiency, then productivity is improved, but suctioning effect deteriorates
Solution Approach 1:
The piston performs periodic reciprocating motions with optimized timing and duration for each stroke. This periodic action allows sufficient time for negative pressure to build up during each suction phase while maintaining high overall massaging efficiency through controlled repetition, preventing suctioning effect deterioration even at increased productivity rates.
Solution Approach 2:
The system optimizes parameters such as reciprocation speed, stroke length, and duty cycle to achieve the best balance between productivity and suctioning effect. By adjusting these parameters, the device can operate at higher productivity levels while maintaining effective suctioning through optimized negative pressure generation timing.
