Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical parts (springs and levers) are used as driving units, then the device can provide vibration motion, but mechanical wear-out and metal fatigue reduce service life and increase maintenance cost
Solution Approach 1:
The patent replaces the conventional mechanical driving system (springs and levers) with an electromagnetic driving system consisting of permanent magnets and electromagnets. This substitution eliminates mechanical contact and friction, thereby eliminating mechanical wear-out and metal fatigue, which directly improves service life and reduces maintenance costs while maintaining the vibration function.
2Ease of operation
If ordinary electromagnets are used to support user weight, then the device can function, but high electricity consumption is necessary
Solution Approach 1:
The patent applies different functional qualities to different parts of the magnetic system: permanent magnets provide static magnetic fields for supporting user weight without consuming electricity, while electromagnets provide dynamic magnetic fields for generating vibration. This local differentiation of magnetic source functions reduces overall electricity consumption while maintaining device functionality.
Solution Approach 2:
The electromagnets operate in periodic alternating current cycles, switching between attraction and repulsion phases to generate vibration. This periodic action allows the system to achieve vibration function with intermittent energy input rather than continuous high power consumption, reducing overall electricity usage.
3Device complexity
If no magnetic shielding facility is used, then the system structure is simpler, but users may be surrounded by magnetic field leakage which produces undesirable influences
Solution Approach 1:
The patent introduces magnetic shielding materials as an intermediary substance between the magnetic components and the user environment. These shielding materials selectively block and redirect magnetic field lines, preventing harmful magnetic field leakage from reaching users while containing the magnetic field within the device structure, thus protecting users without significantly complicating the overall system.
4Reliability
If mechanical parts are eliminated in favor of magnetic fields, then the system has increased reliability, but magnetic field control and shielding become necessary
Solution Approach 1:
The patent replaces mechanical contact-based vibration generation with magnetic field-based vibration generation. By using the interaction between permanent magnets and electromagnets, the system achieves reliable contactless force transmission, eliminating mechanical wear and improving reliability while managing the complexity through straightforward electromagnetic control.
