Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional massagers are limited in their ability to target multiple sore body parts simultaneously, require separate devices for different massage needs, and are bulky and costly when multiple units are needed.
Innovation Solution
A multifunctional massager design featuring a frame with symmetrical connecting bases, a driving motor, eccentric wheels, connecting rods, and driven shafts with massage heads, allowing for adjustable positioning and reciprocal motion to massage various body parts without the need for multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate massagers are purchased to massage different body parts, then the massage functionality for different parts is improved, but the device complexity and storage space requirements increase
Solution Approach 1:
The massager device is designed with multiple massage heads that can target different body parts (neck, shoulder, back, waist, legs, feet) using a single unified device. The device incorporates various massage mechanisms including rolling massage heads, kneading massage heads, and vibration massage heads, allowing one device to perform multiple massage functions that would otherwise require separate devices.
Solution Approach 2:
The patent combines multiple massage mechanisms and functional components into a single integrated massager device. Different massage heads and mechanisms are merged into one unit that can be positioned and adjusted to massage various body parts, eliminating the need for multiple separate massagers.

Different massage heads and mechanisms are merged into one unit that can be positioned and adjusted to massage various body parts, eliminating the need for multiple separate massagers.
3Device complexity
If conventional massagers are used for single part massage, then the device complexity is reduced, but the adaptability to massage different body parts deteriorates
Solution Approach 1:
The massager device is designed with multiple massage heads that can target different body parts (neck, shoulder, back, waist, legs, feet) using a single unified device. The device incorporates various massage mechanisms including rolling massage heads, kneading massage heads, and vibration massage heads, allowing one device to perform multiple massage functions that would otherwise require separate devices.
Solution Approach 2:
The massager incorporates adjustable and movable components including swing arms that can pivot, massage heads that can move along rails, and positioning mechanisms that allow the device to be configured for different body parts. This dynamic adjustability enables a single device to adapt to multiple massage applications.
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 massager is compact, portable, and versatile, enabling effective massage of multiple body areas with appropriate kneading action, reducing the need for multiple purchases and storage space.
Implementation Method 1
two eccentric wheels are connected to two ends of the driving shaft, and the eccentric wheels are located at staggered positions, so that the rotation paths of the two eccentric wheels are opposite
Implementation Method 2
The two connecting rods are respectively connected to the two eccentric wheels at the ends thereof, and the two connecting rods are respectively extended outward in staggered directions

AI summary
A multifunctional massager may include a frame body, and two first connecting bases are respectively formed at two ends of the frame body at symmetrical positions. Each of the two first connecting bases comprises three connecting bears at the inner surface thereof, and the connecting bears on the two first connecting bases are located at corresponding positions. An accommodating space is formed between the two first connecting bases. A massage member installed on the fame body between the two first connecting bases comprises a driving motor, a driving shaft, two connecting rods, and two driven shafts. The driving motor is connected to and drives the driving shaft, and two eccentric wheels are connected to two ends of the driving shaft. The two eccentric wheels are adapted to eccentrically drive the two connecting rods to carry out the reciprocating actions of internal pull and external push.
