Negative-Pressure Massage Cup Buffer Rubber Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing negative-pressure massage cups are prone to damage and noise due to collisions, as the vibrator, being heavier, rotates and hits the ground when the cup is dropped.
Innovation Solution
A negative-pressure massage cup design featuring a buffer rubber on the outer case, which absorbs the impact during a fall, preventing damage to the vibrator and reducing noise from internal component dislocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the vibrator is installed on the outside of the cup body, then the mass distribution is unbalanced causing the vibrator to rotate downward during free fall, but this leads to the vibrator hitting the ground and causing damage or noise
Solution Approach 1:
A buffer rubber is installed on the outer case at the position where the vibrator will rotate to during free fall. This buffer rubber absorbs the impact when the vibrator hits it during accidental drops, preventing damage to the vibrator and reducing noise from internal component dislocation.
2Device complexity
If the vibrator is installed on the outside of the cup body, then the structure is simpler, but the mass distribution causes the cup to rotate during free fall leading to damage
Solution Approach 1:
The buffer rubber is pre-installed on the outer case at the strategic position where the vibrator will rotate to during free fall. This beforehand cushioning prevents the harmful impact without requiring a change in the simple external installation structure of the vibrator.
Solution Approach 2:
The buffer rubber acts as an intermediary element between the vibrator and the external environment. It absorbs the impact energy during free fall collisions, protecting the vibrator while maintaining the simple external installation structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The buffer rubber effectively absorbs the impact of collisions, enhancing the durability of the negative-pressure massage cup by preventing damage to the vibrator and reducing noise from internal component dislocation.
Implementation Method 1
the buffer rubber downward to absorb and reduce an impact caused by a collision to the negative-pressure massage cup
Implementation Method 2
While the negative-pressure massage cup is free falling, the cup body is rotated by a gravity loaded on the vibration mechanism

AI summary
A negative-pressure massage cup includes a cup body having a first installing portion on an outer surface thereof, a vibration mechanism having an outer case, a vibrator disposed in the outer case and a second installing portion and a third installing portion respectively disposed on two opposite sides of the outer case, and a buffer rubber disposed on the second installing portion. The third installing portion is removably disposed on the first installing portion. While the negative-pressure massage cup is free falling, the cup body is rotated by a gravity loaded on the vibration mechanism so as to make the buffer rubber downward to absorb and reduce an impact caused by a collision to the negative-pressure massage cup. The vibration mechanism is prevented from damaging to the vibrator caused by a collision or noise caused by dislocating of the components in the vibrator so as to effectively improve durability.
