The massage chair industry has a few myths that have been sustained over a number of years. One particularly interesting one is the number of motors in a massage chair. The myth claims that the more motors in the shiatsu massage chair the better. Certainly, an increase in the number of motors can enable more functions. Practical reality suggests that more motors means more cost and more real estate and weight of the massage chair. This myth will be explored in this article.
The more motors the better the chair myth is going to be put to the myth buster test. Obviously, having more motors enables more massage options to be possible. Motors are not cheap, in fact they are expensive. Immediately, there is a quality versus quantity tradeoff. Having 18 motors versus 3 motors would make the cost of the 18 motor chair skyrocket, if they use the same quality motor. First concern is the quality level of motors in a massage chair with 18 motors.
Space is another constraint like in any product. Motors used in shiatsu massage chairs are not small motors and must be allocated space. As the number of motors increases, then more mechanisms must be installed around each motor taking up more space. Motors weigh from 2 lbs to 5 lbs each. A massage chair having 3 motors would have 6 lbs in motor weight, whereas, as a massage chair having 18 motors would have 36 lbs each or if 5 lbs each 90 lbs, just in motors. More motors equal more weight.
How are high end luxury massage chairs designed with motors? Most manufacturers use 3 high quality motors. One for the kneading massage, one for the tapping massage and the third motor for moving the roller unit up and down. Software synchronizes the movements of the motors and running the tapping and kneading motors together produces the shiatsu massage.
There is a 5 motor design where the kneading and tapping use two motors each. This is done by having a motor on both the left and right side rollers for both the kneading and tapping. Having 2 motors for kneading splits the duty and should lead to longer motor life. Did it make any difference in the massage capabilities? There was no noticeable difference. Is more better?
If the motor does not create a new and unique massage, then what value does it add? Why have more motors and potentially more problems? The simpler the design, the higher the quality and the less problems down the road. Remember, each motor needs to have controls, software, wiring, etc. to integrate it into the overall massage chair. This drives complexity, increases the testing required to ensure quality and if cheaper motors are substituted, then reduces reliability. Do not buy into the myth that more motors the better for a shiatsu massage chair. Simple is always better!
