Solution Overview

Problem

Water leakage during water aided endoscopy procedures poses challenges, as it interferes with the procedure and requires cleanup, and many endoscopic tools are not suitable for use in fluidic environments, leading to inefficiencies and risks.

Innovation Solution

A multi-functional plug and specialized tools are designed to create a sealed environment within the body cavity, using valves, balloons, and pumps to maintain a watertight seal, along with specialized fluids and image-enhancing solutions to improve visibility and tool functionality in a liquid environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If water is used to fill the body cavity for endoscopy, then image magnification and reduced distention are achieved, but water leakage occurs which interferes with the procedure and requires cleanup

Engineering Contradiction:
Improveimage magnificationVSAvoidwater leakage
Core Design Contradiction:
Illumination intensityVSObject-generated harmful factors

Solution Approach 1:

A sealed plug device is introduced as an intermediary component between the body cavity and the external environment. The plug includes a base pad with an expandable portion that creates a water-tight seal at the opening, preventing water from leaking outward while allowing the cavity to remain filled with water for enhanced imaging.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The plug incorporates a flexible expandable portion (such as a balloon or collapsible structure) that can be inflated to press against the walls of the body cavity opening. This flexible membrane creates an effective seal that accommodates the water-filled environment while preventing leakage, and allows tools to pass through when needed.

Inventive Principle:
Principle #30Flexible shells and thin films

2Object-generated harmful factors

If a sealed environment is created to prevent water leakage, then water leakage is prevented, but device complexity increases due to multiple components needed for sealing and tool passage

Engineering Contradiction:
Improvewater leakage preventionVSAvoiddevice complexity
Core Design Contradiction:
Object-generated harmful factorsVSDevice complexity

Solution Approach 1:

The plug is designed as a multi-functional device that simultaneously provides sealing to prevent water leakage, creates a stable platform for tool insertion, and maintains patency of the opening. The single device integrates multiple functions that would otherwise require separate components, reducing overall system complexity while achieving effective water containment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the sealing function, tool passage function, and opening maintenance function into a single integrated plug device. By merging these functions into one component rather than using separate devices, the overall system complexity is reduced while still achieving effective water leakage prevention and tool accessibility.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If standard endoscopic tools are used in water aided endoscopy, then tool availability is maintained, but tool performance deteriorates due to fluidic environment interference

Engineering Contradiction:
Improvetool availabilityVSAvoidtool performance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The plug creates a localized controlled environment at the opening where water is contained and directed. This local modification of the environment allows standard tools to function more reliably by preventing uncontrolled water exposure and interference at critical interfaces, while still maintaining the overall water-filled beneficial environment in the cavity.

Inventive Principle:
Principle #3Local quality
