Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a rotational motor with eccentric weight is used to generate vibration, then the device can produce vibration motion, but the vibration intensity is weak at low frequencies and the movement accuracy is poor
Solution Approach 1:
The patent replaces the rotational mechanical system (motor with eccentric weight) with an electromagnetic system (electromagnet and bobbin coil). The electromagnet generates a magnetic field that directly acts on the bobbin coil to produce vertical linear motion, eliminating the need for rotational-to-linear conversion and achieving both high vibration intensity and precise vertical movement control.
Solution Approach 2:
The patent changes the operating parameters by using a magnetic gap type structure where the bobbin coil is disposed within the magnetic gap of the electromagnet. This allows for strong magnetic force generation at low frequencies (20 Hz or less) and enables accurate control of the vibration plate's vertical movement through electrical parameter control rather than mechanical rotation.
2Object-generated harmful factors
If a rotational motor with eccentric weight is used, then vibration motion can be produced, but structural durability deteriorates and noise increases
Solution Approach 1:
The patent eliminates the rotating mechanical components (bearings, eccentric weights, rotational shafts) by substituting them with an electromagnetic actuation system. The electromagnet and bobbin coil configuration produces linear vibration motion without rotation, thereby eliminating bearing wear, reducing noise from mechanical contact, and improving structural durability.
3Reliability
If a conventional motor is used as power generation source, then the device can operate, but partial wear of bearings becomes severe
Solution Approach 1:
The patent replaces the conventional rotational motor with an electromagnetic vibration generation system consisting of an electromagnet and bobbin coil. This substitution eliminates the need for bearings and rotating mechanical parts, thereby eliminating partial wear issues while simplifying the overall mechanical structure.
4Object-affected harmful factors
If a rotating-type vertical movement vibrator is used, then vibration can be produced, but it gives burden to articulation of the human body
Solution Approach 1:
Instead of using rotational motion that converts to vertical vibration through eccentric weights, the patent inverts the approach by using direct electromagnetic actuation to produce pure vertical linear motion. This inverted approach eliminates lateral or deviated movement components that would burden human articulations, making the exercise equipment safer and more suitable for users with joint concerns.

AI summary
A vertical movement vibrator of a magnetic gap type is provided. The vibrator can provide a sufficient vertical movement force by a structure that a bobbin coil connected to a vibration plate is disposed in a magnetic gap of a magnetic circuit. The vibrator includes a magnetic circuit which forms an annular magnetic gap, and forms a DC magnetic field in the magnetic gap, a driving coil which is movably inserted into the magnetic gap, the driving coil being vibrated up and down when a driving signal is applied, a driving signal supply unit for supplying the driving signal, a vibration plate to the lower side of which the bobbin is attached to accomplish vibration up and down, a vertical movement guide unit for guiding the vibration plate to perform vertical movement, and a unit which limits a movement range of the vibration plate, and simultaneously absorbs an impact.
