Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvepipe assemblyVSAvoidpipe falling risk
Core Design Contradiction:
Ease of manufactureVSReliability

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.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If the smoke-absorbing pipe has fixed length, then the structure is simple, but it cannot be adjusted for various surgical needs

Engineering Contradiction:
Improvepipe structureVSAvoidpipe length adjustment
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improvesurgical timeVSAvoidbutton sticking risk
Core Design Contradiction:
Duration of action of moving objectVSReliability

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.

Inventive Principle:
Principle #2Taking out (Extraction)

4Device complexity

If the electrode and smoke-absorbing pipe are integrated, then the structure is compact, but replacement and cleaning become troublesome

Engineering Contradiction:
Improvestructure compactnessVSAvoidelectrode and pipe maintenance
Core Design Contradiction:
Device complexityVSEase of repair

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.

Inventive Principle:
Principle #1Segmentation
