Compact Neck and Shoulder Massager With Detachable Massage Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neck and shoulder massagers have large sizes due to separate shiatsu and kneading massage groups, high production costs, and inconvenient cleaning and replacement processes, including the need to remove and replace the entire massage machine core when changing massage heads.
Innovation Solution
A neck and shoulder massager design featuring a detachable massage head, exposed push rods, and detachable shoulder straps, with a compact driving assembly housed within a modular structure, allowing for independent cleaning and replacement of massage heads and straps, and reducing the need for a leather cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate shiatsu massage group and kneading massage group are used, then massage function is improved, but device size increases
Solution Approach 1:
The patent combines the shiatsu massage rod and kneading massage head into a single integrated assembly that shares common mounting and driving mechanisms. The driving assembly includes a motor that can simultaneously control both the shiatsu rod's vertical movement and the kneading head's rotation, eliminating the need for separate driving systems and reducing overall device volume while maintaining dual massage functions.
Solution Approach 2:
The massage assembly is designed with multi-functional components where the driving assembly serves multiple purposes: it drives the shiatsu rod up and down, rotates the kneading massage head, and can independently control each function. This universal driving system allows one mechanism to perform multiple massage functions, reducing the number of components needed and compacting the device structure.
2Object-affected harmful factors
If cloth cover is used to cover massage machine core, then massage effect is improved, but cleaning convenience deteriorates
Solution Approach 1:
The patent divides the massage system into separable components: the massage head with massage balls is detachably mounted on the driving assembly, and the cloth cover can be removed independently. This segmentation allows users to easily remove and clean the cloth cover without disassembling the entire massage machine core, improving cleaning convenience while maintaining the massage effect through the exposed massage balls.
Solution Approach 2:
The patent extracts the cloth cover as a separate, removable component from the massage machine core. The cloth cover can be taken off independently for cleaning or replacement without affecting the underlying driving assembly or massage mechanism. This extraction allows the massage balls to be directly accessible for effective massage while enabling easy maintenance of the cloth cover.
3Device complexity
If massage head and massage seat are integrated, then structural simplicity is improved, but replacement convenience deteriorates
Solution Approach 1:
The patent segments the massage head from the massage seat, making the massage head detachably mounted on the driving assembly. This allows the massage head to be independently replaced without replacing the entire driving assembly or massage seat. The segmented design maintains structural simplicity through standardized mounting interfaces while significantly improving replacement convenience for worn or damaged massage heads.
4Reliability
If entire massage machine core is replaced when changing massage head, then reliability is improved, but replacement cost increases
Solution Approach 1:
The patent segments the replaceable massage head from the permanent driving assembly, allowing only the worn massage head to be replaced rather than the entire machine core. This segmentation maintains system reliability by ensuring the driving assembly remains robust and reliable while reducing replacement costs by allowing selective replacement of only the consumable massage head component.
Solution Approach 2:
The patent enables discarding and replacing only the worn massage head while recovering and retaining the valuable driving assembly. The detachable design allows users to discard the worn massage head and install a new one without wasting the expensive motor and mechanism components, thereby reducing overall replacement costs while maintaining system reliability through the preserved driving assembly.
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 design provides a more compact, cost-effective, and user-friendly massager with improved massage efficacy, reduced replacement costs, and enhanced consumer experience through detachable components and simplified maintenance.

AI summary
Disclosed is a neck and shoulder massager, which includes a housing, a machine core box, a driving assembly, a push rod, a mounting seat, a massage head and two shoulder straps. According to the present disclosure, the driving assembly is arranged in the housing, the massage head is mounted to the mounting seat protruding from the housing, and the push rod also protrudes from the housing. Since the massage head and the push rod are both exposed out of the housing of the massager, the massager can directly make contact with the human body for massaging the shoulders and the neck without being sleeved with a leather cover, so that the massager fits the human body more closely and has a good massage effect.
