Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the metal end of the external electrode is exposed out of the insulating layer to discharge normal saline, then the water supply function is achieved, but current leakage and scalding hazards occur
Solution Approach 1:
The patent introduces an insulating layer as an intermediary substance between the metal electrode and the surrounding environment. This insulating layer covers the metal electrode completely, preventing direct contact that would cause current leakage and scalding, while still allowing normal saline to be discharged through the electrode structure safely
Solution Approach 2:
The patent uses a thin film insulating layer that completely covers the metal electrode. This thin film structure provides electrical insulation and protection against scalding while maintaining the functional discharge of normal saline through the electrode, resolving the contradiction between water supply capability and safety
2Device complexity
If the flow guiding hole is installed on the external electrode to discharge normal saline, then the water supply structure is simplified, but water supply capacity is insufficient and water supply is non-uniform
Solution Approach 1:
The patent segments the water supply function by introducing multiple components: the external electrode with flow guiding hole, the water absorption tube sheathed in the tubular loop electrode, and the effluent flow guiding component. This segmentation allows each component to perform its specific function optimally, ensuring uniform and sufficient water supply while maintaining reasonable structural complexity
3Device complexity
If normal saline is flowed to the water inlet place dependent on water flow pressure and gravity action, then the water supply mechanism is simple, but feed liquid is unstable and uncontrollable especially when the electrode head is not downward
Solution Approach 1:
The patent introduces the effluent flow guiding component as an intermediary structure that actively guides normal saline from the water absorption tube to the water inlet place of the electrode head. This component ensures stable and controllable feed liquid delivery regardless of electrode orientation, overcoming the limitations of passive gravity-based flow
Solution Approach 2:
The effluent flow guiding component serves multiple functions: it guides normal saline flow, maintains feed liquid stability, and enables the electrode to function reliably in various orientations (upward, downward, or at angles). This multi-functionality resolves the contradiction between simple mechanism and stable operation
4Duration of action of stationary object
If the insulating layer adjacent to the working electrode end is used for multiple times, then the electrode reusability is improved, but deformation is easily generated causing poor water supply
Solution Approach 1:
The patent employs a thin film insulating layer that completely covers the metal electrode. This thin film structure is designed to maintain its integrity and insulating properties even after multiple uses, preventing deformation that would compromise water supply function while enabling electrode reusability
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 electrode provides a reliable, safe, and stable water supply, preventing current leakage and scalding, ensuring effective electrical conductivity and universality for both tonsil and adenoid resection operations, while reducing consumable costs and maintaining high operational efficiency.
Implementation Method 1
an electric field in certain frequency is used, electrolyte between a plasma operation electrode and a target tissue is converted into a low-temperature plasma state, a highly aggregated plasma thin layer is formed at a front end of the operation electrode
Implementation Method 2
the strong electric field is capable of enabling free charged particles in the plasma thin layer to acquire enough energy, and transmitting the energy to the target tissue, a molecular bond for forming a cell component in the target tissue is disaggregated, cells in the target tissue are disintegrated
Implementation Method 3
the effluent flow guiding component is correspondingly installed at the water outlet hole, and sealed and connected on an outer wall of the tubular loop electrode; a water injecting channel is formed between the effluent flow guiding component and the tubular loop electrode
Implementation Method 4
a lower side 201 of an external electrode 20 exposed out of an insulating layer is provided with a flow guiding hole 202... because a metal end of the external electrode 20 is exposed out of the insulating layer, not only a potential safety hazard of easy current leakage exists, but also an exposed head of the external electrode 20 is easy to scald tissues of other parts
