Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional massage device uses two drive devices with separate transmission structures, then each massage plate can be driven independently, but the overall structure becomes complex and bulky
Solution Approach 1:
The patent combines two separate drive devices into a single drive device that drives both massage plates through a shared transmission mechanism. The shaking shaft with eccentric wheels at both ends allows one motor to simultaneously drive both massage plates, reducing the number of drive devices from two to one while maintaining independent operation capability.
Solution Approach 2:
The single drive device serves multiple functions by driving both massage plates through the shaking shaft mechanism. The transmission mechanism is designed to be universal, allowing one drive device to perform the work of two separate drive devices while enabling independent control of each massage plate through the belt-pulley system.
2Ease of operation
If a conventional massage device uses separate transmission structures for each massage plate, then each plate can be controlled independently, but the overall device size increases
Solution Approach 1:
The patent merges two separate transmission structures into a single integrated transmission mechanism. The shaking shaft with eccentric wheels and the belt-pulley system allow one drive device to control both massage plates, significantly reducing the space required for transmission components while maintaining independent control capability.
3Device complexity
If a massage machine uses a single drive device with a transmission mechanism, then the structure is simplified and size is reduced, but the transmission mechanism must efficiently connect two massage plate units
Solution Approach 1:
The patent employs eccentric wheels mounted on the shaking shaft to generate mechanical vibration that drives the massage plates. The eccentric mechanism converts rotational motion from the single drive device into oscillating motion, providing reliable and efficient transmission of force to both massage plates through the vibration-generating eccentric wheels.
Solution Approach 2:
The shaking shaft acts as an intermediary component that receives rotational motion from the single drive device and distributes it to both massage plates through the eccentric wheels. The belt-pulley system serves as another intermediary, allowing flexible power transmission and independent control of each massage plate while maintaining system reliability.

AI summary
A massage machine includes a casing unit, a drive device, a transmission mechanism, and two massage plate units. Two ends of the transmission mechanism are linked with the massage plate units, respectively. The drive device drives the transmission mechanism. The transmission mechanism and the drive device are disposed in the casing unit. The massage plate units are disposed on the casing unit. The massage machine uses a single drive device to drive the transmission mechanism, so that the transmission mechanism can link the two massage plate units to massage a user.
