Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If amplification is made to a degree of giving a burden to an object, then vibration amplification is achieved, but the object may fail or be damaged
Solution Approach 1:
The patent employs resonance-based mechanical vibration amplification where the amplifier is tuned to the natural frequency of the object. This allows efficient energy transfer and amplification without requiring excessive force that would burden or damage the object. The resonance phenomenon enables the system to achieve high amplification factors while operating within safe stress limits of the object.
2Loss of energy
If energy is collected from vibration, then energy harvesting is achieved, but the energy may not be converted into usable electromagnetic wave energy
Solution Approach 1:
The patent replaces direct mechanical energy conversion with an electromagnetic conversion mechanism. The vibration energy is first converted to mechanical motion of a coil within a magnetic field, which then generates electromagnetic energy through electromagnetic induction. This substitution enables efficient conversion of collected vibration energy into usable electromagnetic wave energy, solving the conversion problem while maintaining manufacturing feasibility.
3Adaptability or versatility
If a comprehensive natural frequency band is manufactured, then wide frequency range amplification is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent employs a dynamically adjustable amplifier design where the natural frequency can be tuned or adapted to match different objects. Rather than manufacturing fixed-frequency amplifiers for each frequency band, the system uses adjustable parameters (such as mass, stiffness, or geometric dimensions) to dynamically configure the amplifier for the specific natural frequency of the target object, thereby achieving comprehensive frequency coverage without proportionally increasing manufacturing complexity.

AI summary
An apparatus and method for designing an amplifier are proposed. The method may include measuring a frequency of an object by coming into contact with the object wherein the object generates vibration energy, and calculating a natural frequency of the object. The method may also include, in correspondence to a selection of one vibration energy amplifier from among a plurality of vibration energy amplifiers that are preset, loading specification information about the selected vibration energy amplifier. The method may further include specifying at least one parameter in the specification information of the vibration energy amplifier so as to coincide with the natural frequency of the object.
