Solution Overview

Problem

Existing electrosurgical systems face issues with conduit leaks during quality inspection, leading to the entire system being discarded, as conduits need to be long enough to span the entire system for effective cooling fluid delivery and energy transmission.

Innovation Solution

A conduit junction that interconnects sections of the electrosurgical system, allowing conduits and conductors to be shorter, facilitating efficient leak testing and enabling only flawed portions to be replaced while preserving the rest of the system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the entire electrosurgical system is discarded when a leak is found in the conduits, then quality control is maintained, but material waste increases and maintenance costs rise

Engineering Contradiction:
Improvequality controlVSAvoidmaterial waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The electrosurgical system is divided into modular sections that can be independently tested and replaced. The conduit junction serves as a segmentation point, allowing the system to be divided into replaceable segments rather than requiring disposal of the entire system when a leak is detected.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the entire electrosurgical system is discarded when a leak is found, then quality control is maintained, but maintenance costs increase

Engineering Contradiction:
Improvequality controlVSAvoidmaintenance costs
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The system is segmented into modular sections with the conduit junction as a key interface. This segmentation enables cost-effective repair by allowing replacement of only the defective section rather than the entire system, directly reducing maintenance costs while maintaining quality control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of discarding the entire system, the invention enables discarding and recovering only the faulty conduit section. The modular design with standardized junctions allows the remaining functional portions to be recovered and reused, reducing maintenance costs.

Inventive Principle:
Principle #34Discarding and recovering

3Reliability

If conduits are made longer to reach the surgical tip, then cooling fluid delivery is improved, but leak risk increases

Engineering Contradiction:
Improvecooling fluid deliveryVSAvoidleak risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The conduit system is segmented into shorter sections connected through standardized junctions. This segmentation reduces the length of individual conduit sections, thereby reducing leak risk in each section while maintaining overall cooling fluid delivery capability through the modular assembly.

Inventive Principle:
Principle #1Segmentation

4Stability of the object's composition

If the electrosurgical system is designed as a single integrated unit, then system stability is improved, but repairability deteriorates

Engineering Contradiction:
Improvesystem stabilityVSAvoidrepairability
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The system uses segmented design with standardized conduit junctions that maintain system stability through consistent interfaces while enabling easy repair by allowing replacement of individual sections without affecting the overall system integrity.

Inventive Principle:
Principle #1Segmentation

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 leak testing and reduces waste by allowing only defective parts to be replaced, while maintaining the functionality of the electrosurgical system.

Implementation Method 1
