Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a split smoke-absorbing pipe structure is used, then the pipe can be assembled, but it has a falling risk which increases surgery risk
Solution Approach 1:
The patent integrates the smoke-absorbing pipe with the electrotome handle into a unified structure, eliminating the split design. The pipe is now an integrated component that cannot detach or fall during surgery, directly resolving the reliability issue while maintaining manufacturability through modular integration segments.
2Device complexity
If the smoke-absorbing pipe has fixed length, then the structure is simple, but it cannot be adjusted for various surgical needs
Solution Approach 1:
The patent implements a telescopic pipe structure with extendable and retractable segments, allowing the pipe length to be dynamically adjusted during surgery. This dynamic design enables adaptation to various surgical needs while maintaining a compact form when retracted, balancing complexity and versatility.
Solution Approach 2:
The pipe is divided into multiple telescopic segments that can slide relative to each other, enabling length adjustment. This segmentation allows the pipe to achieve variable lengths for different surgical requirements while maintaining structural integrity through precise mechanical coupling between segments.
3Duration of action of moving object
If the electrotome is used for long surgical time, then more procedures can be performed, but blood and body fluids adhere to the button increasing sticking risk
Solution Approach 1:
The patent extracts the PCB circuit component from the handle interior and relocates it to an independent protective housing. This separation prevents bodily fluids from reaching and adhering to the circuit board, eliminating the button sticking risk during long surgical procedures while maintaining full operational duration.
4Device complexity
If the electrode and smoke-absorbing pipe are integrated, then the structure is compact, but replacement and cleaning become troublesome
Solution Approach 1:
The patent divides the integrated structure into modular segments - the electrode assembly, smoke-absorbing pipe sections, and connection interfaces are designed as separable units. This segmentation allows individual components to be quickly replaced or cleaned without disassembling the entire device, maintaining compactness while enabling easy maintenance.
