Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If invasive radiofrequency treatment using microneedles is used, then radiofrequency energy can be directly delivered to the dermis, but the patient experiences fear and pain due to invasiveness
Solution Approach 1:
The patent combines invasive microneedle treatment and non-invasive contact electrode treatment into a single integrated device. The handpiece contains both needle electrodes that can penetrate the skin and contact electrodes that remain on the skin surface, allowing both treatment modes to be available in one device. This merging resolves the contradiction by providing both the effective deep dermis delivery of invasive methods and the comfort of non-invasive methods within the same system.
Solution Approach 2:
The integrated handpiece is designed to perform multiple functions: it can operate in invasive mode using needle electrodes, in non-invasive mode using contact electrodes, and potentially in combination mode. This multi-functionality allows the device to adapt to different treatment requirements and patient comfort levels, resolving the contradiction between treatment effectiveness and patient comfort by offering universal applicability across different treatment philosophies.
2Object-affected harmful factors
If non-invasive radiofrequency treatment with contact electrode is used, then patient comfort is improved, but thermal energy cannot be effectively delivered to the dermis beneath the epidermis
Solution Approach 1:
The patent merges the advantages of both contact electrode and microneedle approaches by integrating them in a single handpiece. The contact electrodes provide patient comfort by avoiding needle penetration, while the needle electrodes provide effective deep dermal access when needed. The system can selectively activate either mode or both simultaneously, resolving the contradiction between comfort and effective energy delivery to the dermis.
Solution Approach 2:
The device incorporates dynamic control capabilities where the practitioner can adjust between different treatment modes (invasive, non-invasive, or combination) based on real-time treatment requirements and patient response. The radiofrequency generator can dynamically adjust parameters and the system can switch between needle and contact electrode activation, providing adaptability that resolves the static contradiction between comfort and effectiveness.
3Reliability
If separate invasive and non-invasive radiofrequency devices are used, then each treatment method can be optimized, but rapid switching between methods is difficult and treatment efficiency is reduced
Solution Approach 1:
The patent merges separate invasive and non-invasive radiofrequency treatment capabilities into a single integrated handpiece and control system. Both needle electrodes and contact electrodes are housed in the same handpiece, connected to a unified radiofrequency generator that can control both types of electrodes. This eliminates the need to physically switch between separate devices, allowing rapid mode changes and improving treatment efficiency while maintaining optimization of both treatment methods.
Solution Approach 2:
The integrated system provides universal functionality by incorporating both invasive and non-invasive treatment capabilities in one device. The single handpiece can perform microneedle radiofrequency treatment, contact electrode radiofrequency treatment, and potentially combination treatments, all controlled by one system. This multi-functionality resolves the productivity contradiction by eliminating device switching time while maintaining the optimized performance of both treatment modalities.
4Reliability
If invasive treatment and non-invasive treatment are performed separately using different devices, then each treatment can be performed with dedicated equipment, but simultaneous treatment cannot be realized
Solution Approach 1:
The patent merges invasive and non-invasive treatment capabilities into a single handpiece that can operate both needle electrodes and contact electrodes simultaneously or sequentially. The radiofrequency generator is designed to control multiple electrode types with independent channels, allowing simultaneous activation of both invasive and non-invasive treatment modes. This merging resolves the contradiction by providing dedicated equipment performance for each mode while enabling their simultaneous operation through integrated control.
Solution Approach 2:
The integrated system uses segmentation by providing separate control channels for needle electrodes and contact electrodes within the same handpiece. Each electrode type has its own radiofrequency output channel, allowing independent control and simultaneous operation. This segmentation approach maintains the dedicated equipment performance for each treatment mode while enabling versatility through simultaneous treatment capability.
