Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing negative pressure massage apparatuses generate significant noise due to the use of air pumps, which compromises the massage experience.
Innovation Solution
A massager design that includes a housing with massage ports, an air pressure generating member with isolated air pressure generating cavities, and a driving device that uses a motor to deform a separating body, altering the volume of the air pressure generating cavities to create an air pressure difference between massage ports, thereby reducing noise and enhancing the massage experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If air pumps are used for negative pressure massage, then massage function is achieved, but significant noise is generated
Solution Approach 1:
The patent replaces the traditional air pump mechanical system with a motor-driven separating body system. The motor drives the separating body to deform or oscillate, changing the volume of air pressure generating cavities to create pressure differences, thereby eliminating the noise generated by air pumps while maintaining the massage function.
Solution Approach 2:
The patent divides the air pressure generating cavity into multiple isolated cavities using a separating body. This segmentation allows each cavity to be independently controlled and creates multiple massage ports, enabling simultaneous air compression and negative pressure massage while reducing noise through distributed pressure generation.
2Object-affected harmful factors
If a motor is used to drive the separating body, then noise is reduced, but device complexity increases
Solution Approach 1:
The separating body serves multiple functions: it separates the air pressure generating cavity into isolated cavities, acts as a movable piston to change cavity volumes, and drives the creation of pressure differences. This multi-functionality reduces the need for additional separate components, thereby managing device complexity while achieving noise reduction.

Function Achieved in This Case
The massager effectively performs air stimulation massage with reduced noise, improving the overall massage experience by providing both air compression and negative pressure massage without the loud operation of air pumps.
Implementation Method 1
increase or decrease a volume of at least one of the air pressure generating cavities to decrease or increase an internal air pressure, so that an air pressure difference is formed between the at least two massage ports
