Solution Overview
Problem
Current massage devices often provide superficial and ineffective massages, failing to deliver real therapeutic benefits.
Innovation Solution
A percussive massage device with a housing, motor, and push rod assembly that reciprocates in response to motor activation, featuring multiple handle portions for ergonomic grip and adjustable frequency and amplitude to provide efficient and therapeutically beneficial treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional massage devices are used, then the device structure is simple, but the massage effectiveness is superficial and ineffective
Solution Approach 1:
The patent implements a push rod assembly that reciprocates between extended and retracted positions to deliver dynamic percussive motion. The push rod moves from a first position to a second position and back, creating effective deep tissue massage through controlled mechanical dynamics rather than static or simple oscillating motion
Solution Approach 2:
The housing is divided into multiple handle portions (first handle portion, second handle portion, third handle portion) that can be selectively grasped. This segmentation allows different grip configurations for different body parts while maintaining a cohesive device structure that delivers effective percussive treatment
2Adaptability or versatility
If a single handle configuration is used, then the device structure is simple, but the adaptability to different body parts is limited
Solution Approach 1:
The device incorporates multiple handle portions (first, second, and third handle portions) that can be selectively grasped to accommodate different body parts and user preferences. Each handle portion can be independently grasped, allowing the same device to universally treat various body areas such as back, shoulders, legs, and arms through different grip configurations
3Reliability
If fixed frequency and amplitude are used, then the device control is simple, but the therapeutic effectiveness varies for different muscle conditions
Solution Approach 1:
The device allows adjustment of operational parameters including frequency (oscillations per minute) and amplitude (depth of push rod travel). The motor can operate at variable speeds to change frequency, and the push rod assembly can be adjusted to vary the amplitude of reciprocation, enabling optimization of therapeutic effectiveness for different muscle conditions and treatment goals
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 device delivers efficient and therapeutically beneficial massages by adjusting frequency and amplitude between 15 Hz and 100 Hz and amplitude of 0.15 to 1.0 inches, ensuring effective muscle treatment.
Implementation Method 1
a motor positioned in the housing... operatively connected to the motor and configured to reciprocate in response to activation of the motor
Implementation Method 2
push rod assembly operatively connected to the motor and configured to reciprocate... The actuated output is configured to reciprocate the treatment structure

AI summary
A percussive massage device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, and a push rod assembly operatively connected to the motor and configured to reciprocate in response to activation of the motor. The housing includes first, second and third handle portions that cooperate to define a handle opening, wherein the first handle portion defines a first axis, the second handle portion defines a second axis and the third handle portion defines a third axis, and wherein the first, second and third axes cooperate to form a triangle.
