Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical treatment using mechanical waves and/or pressure is used, then treatment of cellulite or adipose cells is achieved, but risk of panniculitis and non-homogenous results occur
Solution Approach 1:
The patent replaces mechanical treatment methods (mechanical waves, pressure) with electromagnetic field-based treatment. The electromagnetic field induces muscle contractions and thermal effects that achieve fat reduction and skin tightening without the mechanical trauma that causes panniculitis, thereby eliminating the harmful mechanical effects while maintaining treatment efficacy.
Solution Approach 2:
The patent changes the fundamental treatment parameter from mechanical force to electromagnetic field intensity and frequency. By controlling the electromagnetic field parameters (strength, frequency, pulse duration), the treatment achieves homogeneous energy distribution in the tissue, avoiding the non-homogenous results associated with mechanical methods while maintaining safety.
2Reliability
If thermal treatment is applied, then visual appearance of skin is enhanced, but risk of overheating and thermal damage occurs
Solution Approach 1:
The patent employs periodic pulsed electromagnetic field application rather than continuous thermal exposure. The pulsed nature allows tissue cooling between pulses, preventing cumulative overheating and thermal damage while still achieving the desired thermal effects for collagen stimulation and fat reduction during the active pulses.
Solution Approach 2:
The electromagnetic field acts as an intermediary that indirectly produces thermal effects through induced currents and muscle contractions, rather than direct thermal application. This indirect heating mechanism provides better temperature control and reduces the risk of localized overheating and thermal damage to sensitive tissues.
3Power
If magnetic field generating device made of metallic strips or hollow conductors is used, then magnetic field is generated, but significant energy losses due to eddy currents occur
Solution Approach 1:
The patent segments the magnetic field generating device into multiple insulated wire strands rather than using solid metallic strips or hollow conductors. This segmentation breaks up the continuous conductive paths that generate eddy currents, significantly reducing energy losses while maintaining the ability to generate the required magnetic field strength for effective treatment.
Solution Approach 2:
The patent uses a composite structure combining multiple insulated wire strands to create the magnetic field generating device. This composite construction provides both electrical insulation between strands (reducing eddy currents) and sufficient conductive cross-section (maintaining magnetic field generation capability), achieving a balance between energy efficiency and treatment effectiveness.
4Force
If high power magnetic field is applied, then muscle contraction is induced, but treatment duration increases and energy consumption increases
Solution Approach 1:
The patent employs continuous pulsed electromagnetic field application that maintains muscle contraction throughout the treatment period. The high-frequency pulsing ensures continuous stimulation of muscle fibers, maximizing contraction effectiveness and treatment efficiency within a shorter overall treatment time compared to intermittent or low-frequency approaches.
Solution Approach 2:
The patent optimizes electromagnetic field parameters (frequency, pulse width, amplitude) to achieve maximum muscle contraction force within a reduced treatment time. By carefully tuning these parameters, the treatment delivers sufficient mechanical force for effective fat reduction and skin tightening while minimizing total treatment duration and energy consumption.
