Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electrosurgical devices are used to operate in different modes (pressure and gripping), then the versatility of treatment options is improved, but the device complexity and operational constraints increase
Solution Approach 1:
The patent combines both pressure mode and gripping mode functionalities into a single electrosurgical device. The device includes a first electrode with a concave cross-section and a second electrode that can be positioned within the concavity, allowing the same device to operate in either pressure mode (with both electrodes contacting tissue) or gripping mode (with tissue pinched between electrodes), thereby eliminating the need for multiple separate devices
Solution Approach 2:
The electrosurgical device is designed with universal functionality to perform multiple surgical tasks. The articulated structure with movable members allows the device to adapt between different operating modes (pressure and gripping) and different treatment functions (incision and cauterizing) using a single unified platform, making the device versatile across various surgical requirements
2Adaptability or versatility
If electrosurgical devices are frequently changed and adjusted during operation, then the adaptability to different treatment requirements is improved, but the productivity and surgical efficiency deteriorate
Solution Approach 1:
The device incorporates movable members connected by an articulation pivot that allow dynamic reconfiguration between pressure and gripping modes. The members can move closer together or further apart, and the second electrode can be positioned to protrude from or be housed within the first electrode, enabling the surgeon to switch between modes without changing devices, thus maintaining surgical efficiency
3Measurement precision
If energy level and waveform adjustments are made frequently to switch between incision and cauterizing, then the precision of treatment control is improved, but the time consumption and operational complexity increase
Solution Approach 1:
The device allows the surgeon to switch between incision and cauterizing functions by simply changing the operating mode (pressure or gripping) rather than making manual adjustments to energy levels or waveforms. The system self-adapts to different treatment functions through the mechanical configuration of electrode contact, eliminating the need for time-consuming generator adjustments
4Volume of moving object
If the second electrode is fully housed within the first electrode, then the compactness of the device is improved, but the ability to establish independent electrical contacts with tissues deteriorates
Solution Approach 1:
The second electrode is nested within the concave cross-section of the first electrode, allowing compact storage when not in use. However, when the movable members are brought together, the second electrode is positioned to protrude from the first electrode, enabling it to establish independent electrical contact with the tissue while maintaining the compact nested structure during non-operational states
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
Enables efficient and safe treatment of tissues in multiple modes with a single device, reducing the need for frequent adjustments and minimizing risks by maintaining consistent energy delivery, thus improving surgical efficiency and reducing hardware and resource requirements.
Implementation Method 1
The incision and/or cauterizing operations are produced by the heat able to develop at the tissues where the energy is concentrated and/or circulates

AI summary
The invention concerns a multifunctional electrosurgical device for treating biological tissues comprising a first member and a second member linked by a hinge allowing the members to be moved together and apart from each other; the first member comprising, at the front end of same, a first electrode for forming a first electrical contact with the tissues and the second member comprising, at the front end of same, a second electrode for forming a second electrical contact with the tissues. The first electrode has a concave cross-section, capable of partially housing the second electrode and of making the second electrode protrude from the first electrode when the two members are moved together. The device is remarkable in that the electrodes are configured to allow the formation of the first electrical contact on the outer surface of the first electrode and the formation of the second electrical contact on the protruding part of the second electrode.
