Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massagers for shoulders and neck often generate noise, have complex and unreliable structures, and are bulky and heavy, leading to discomfort during use due to the need for multiple driving mechanisms and large size.
Innovation Solution
A massager design featuring a single eccentric transmission component that enables both swinging and eccentric motions, reducing noise and complexity while maintaining structural reliability and minimizing size and weight through a simplified mechanism with a compact driving system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driving mechanisms are used to drive multiple massage heads, then the massage function is improved, but the device complexity and cost increase
Solution Approach 1:
The patent combines multiple driving mechanisms into a single driving mechanism that simultaneously drives both massage heads through a linkage structure. The first connecting piece connects the first massage head to the driving mechanism, while the second connecting piece connects the second massage head to the same driving mechanism,实现ing coordinated operation with reduced complexity
Solution Approach 2:
The single driving mechanism is designed to perform multiple functions by driving both the first and second massage heads through different connecting pieces. The linkage structure allows one driving mechanism to provide the necessary motions for multiple massage heads, reducing the overall number of components needed
2Device complexity
If a linkage structure is used to simultaneously drive various massage heads, then the device complexity is reduced, but the structural reliability deteriorates
Solution Approach 1:
The patent segments the linkage structure into distinct connecting pieces - the first connecting piece for the first massage head and the second connecting piece for the second massage head. Each connecting piece is independently designed and connected to the driving mechanism, allowing for easier maintenance and replacement while maintaining overall system reliability
Solution Approach 2:
The connecting pieces are designed with rotational freedom, allowing them to dynamically adapt to the motion requirements of each massage head. The first connecting piece can rotate relative to the driving mechanism, and the second connecting piece can also rotate, providing flexibility and reducing stress concentration that could compromise reliability
3Adaptability or versatility
If multiple massage heads are equipped on the main body, then the massage coverage is improved, but the massager size and weight increase
Solution Approach 1:
The patent merges the driving functions for multiple massage heads into a single compact driving mechanism located in the main body. By using one driving mechanism with multiple connecting pieces instead of separate driving mechanisms for each massage head, the overall weight of the main body is reduced while still providing multi-point massage capability
4Productivity
If frequent beating motion is used by massage heads, then the massage effect is improved, but noise generation increases
Solution Approach 1:
The patent employs dynamic motion for the massage heads through the rotating connecting pieces. Instead of rigid beating motion, the first massage head and second massage head perform rhythmic movements through the rotational motion of their respective connecting pieces. This dynamic approach provides effective massage while reducing impact noise compared to frequent beating

AI summary
A massager includes a wearing body for wearing on neck and a second massage head. The wearing body includes a cover shell and a driving mechanism installed thereon. The driving mechanism includes a transmission shaft rotatably installed on the cover shell, a second connecting piece eccentrically and rotatably connects the transmission shaft, a movable component movably connects the cover shell, and a swing component pivotally connects the cover shell. The movable component is located on a side of the transmission shaft. The second massage head connects the swing component. The second connecting piece pivotally connects the movable component. The movable component rotatably and slidably connects the swing component. The transmission shaft drives the swing component and the second massage head to swing through the second connecting piece and the movable component when the transmission shaft rotates, thereby forming massage actions on shoulders.
