Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high powered time-varying magnetic field is applied to induce muscle contraction, then aesthetic treatment effectiveness is improved, but energy loss increases due to eddy currents in metallic components
Solution Approach 1:
The patent removes metallic components (strips, wires, hollow conductors) from the magnetic field generating device, extracting the source of eddy current energy loss. The magnetic field is generated without metallic elements that would induce harmful eddy currents, thereby eliminating the energy waste while maintaining treatment effectiveness.
Solution Approach 2:
The patent introduces an intermediary non-metallic material (such as plastic or ceramic) to replace metallic components in the magnetic field generating device. This intermediary material allows the magnetic field to pass through without inducing eddy currents, serving as a mediator between the electrical current source and the target tissue while preventing energy loss.
2Reliability
If thermal treatment is applied to enhance visual appearance, then collagen and elastin production is improved, but risk of overheating and thermal damage increases
Solution Approach 1:
The patent replaces thermal treatment mechanisms with mechanical treatment using mechanical waves (ultrasound, shock waves). This substitution eliminates the risk of overheating and thermal damage while achieving aesthetic improvements through mechanical effects on tissue such as cavitation, vibration, and direct mechanical stimulation.
Solution Approach 2:
The patent changes the treatment parameter from thermal energy to mechanical energy. By using mechanical waves instead of heat, the treatment achieves tissue remodeling and collagen stimulation without the dangerous temperature increases that cause overheating and thermal damage.
3Reliability
If mechanical treatment is used for cellulite and adipose cells, then visual appearance is improved, but risk of panniculitis and non-homogeneous results increases
Solution Approach 1:
The patent merges multiple treatment modalities (mechanical waves, electromagnetic fields, magnetic fields) into a single integrated treatment system. This combination allows simultaneous application of different mechanisms that work together to achieve homogeneous treatment results while reducing the risks associated with any single method, including panniculitis from mechanical treatment alone.
Solution Approach 2:
The patent creates a multi-functional treatment device that can deliver mechanical waves, electromagnetic fields, and magnetic fields through a single system. This universal device addresses multiple treatment needs (cellulite, adipose cells, muscle tone) simultaneously, ensuring homogeneous results across different tissue types while maintaining safety through controlled multi-modal action.
4Device complexity
If metallic strips and hollow conductors are used for magnetic field generation, then device complexity is reduced, but eddy current losses and cooling requirements increase
Solution Approach 1:
The patent extracts and removes all metallic conducting components (strips, hollow conductors, wires) from the magnetic field generating device. By taking out these metallic elements, the device eliminates eddy current losses entirely while maintaining the ability to generate the required magnetic field through non-metallic means, thereby reducing both energy loss and cooling requirements.
Solution Approach 2:
The patent introduces non-metallic intermediary materials (plastic, ceramic, or other electrically insulating materials) to replace metallic components in the magnetic field generation system. These intermediaries allow magnetic field generation without eddy currents, simplifying the device by eliminating complex cooling systems while maintaining structural integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves energy efficiency, reduces adverse events, and achieves more homogeneous temperature distribution, resulting in enhanced visual appearance and muscle contraction, while minimizing side effects like panniculitis.
Implementation Method 1
The magnetic field is time-varying and high powered therefore the method is based on a value of magnetic flux density sufficient to induce at least muscle contraction
Implementation Method 2
Eddy currents induced within the magnetic field generating device create engineering challenges. Existing devices contain magnetic field generating devices which are made of metallic strips, electric wires or hollow conductors. Since the therapy requires large currents, significant losses are caused by induced eddy currents within the magnetic field generating device. Eddy currents lead to production of unwanted heat and therefore there is need to sufficiently cool the magnetic field generating device
