Massage Shower Head with Movable Balls for Simultaneous Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massage shower heads cannot simultaneously provide a shower and massage functions, leading to difficulties in removing dirt generated by scrubbing, as the water outlet must be closed for massage, and the massage balls are prone to falling out when the shower head is moved.
Innovation Solution
A massage shower head design featuring a main body, water outlet cover with openings for massage balls, a multifunctional sealing seat, and a water outlet sleeve, allowing the massage balls to be movably positioned and supported, enabling both shower and massage functions while preventing ball displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water outlet is closed for massage function, then the massage effect is improved, but the shower function cannot be implemented simultaneously and dirt cannot be removed in time
Solution Approach 1:
The shower head is divided into separate functional zones: a front water outlet panel for showering and a rear massage section with accommodation chambers for massage balls. This segmentation allows both functions to operate independently and simultaneously without interfering with each other.
Solution Approach 2:
The shower head integrates multiple functions into a single device: the front panel provides traditional shower function while the rear accommodation chambers provide massage function. Both functions can be used simultaneously, making the device universal and eliminating the need to choose between showering and massaging.
2Ease of manufacture
If the massage ball diameter is slightly less than the accommodation chamber, then the massage ball can be easily installed, but the massage ball may fall out when the shower head is moved transversely
Solution Approach 1:
The massage balls are designed to be movable within the accommodation chambers rather than fixed. The spherical shape allows them to roll freely for massage effect while the chamber geometry prevents them from falling out during normal transverse movement of the shower head.
Solution Approach 2:
The accommodation chambers have an asymmetric design where the opening is smaller than the chamber interior. This creates a retention effect where the massage ball can easily enter during installation but is retained during use, preventing it from falling out when the shower head is moved.
3Reliability
If the flange is used to prevent the massage ball from falling out, then the retention is provided, but it is difficult to prevent the massage ball from falling out when moved transversely
Solution Approach 1:
The massage ball is designed to be movable within the accommodation chamber, allowing it to roll freely for effective massage while the chamber geometry naturally retains the ball during transverse movement. The ball's mobility enhances massage effectiveness while the chamber design prevents accidental dropout.

AI summary
A massage shower head includes a main body, a water outlet cover, and a plurality of massage balls. The main body is provided with a water inlet. A front of the main body is defined as a water outlet side. The water outlet cover covers the water outlet side of the main body. The massage balls are movably disposed between the main body and the water outlet cover. The water outlet cover has a plurality of openings. The massage balls partially extend out from the openings, respectively. The massage balls are arranged on the water outlet side of the shower head to realize the massage function while taking a shower and achieve the effect of scrubbing the user's skin.
