Solution Overview

Problem

Existing fluid collection devices, such as bed pans and urinary catheters, face issues like discomfort, pressure ulcers, spills, and increased risk of urinary tract infections, which are not adequately addressed for individuals with limited mobility or impaired toileting processes.

Innovation Solution

A fluid collection system comprising a fluid collection device with a chamber, a first conduit for fluid communication, a handheld pump unit to create negative pressure for fluid extraction, and a fluid storage container to collect the drawn fluid, providing a more efficient and comfortable solution for fluid management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bed pans are used for fluid collection, then fluid collection capability is provided, but user comfort and hygiene are deteriorated due to discomfort, pressure ulcers, and spills

Engineering Contradiction:

Improvefluid collection capabilityVSAvoiduser comfort and hygiene

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the passive mechanical bed pan system with an active pump-driven fluid removal system. The pump creates negative pressure to automatically draw fluid from the collection chamber through a conduit to a storage container, eliminating the need for manual emptying and reducing spill risks associated with traditional bed pans

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service fluid removal through the automated pump mechanism. The pump unit, when activated, automatically removes fluid from the collection chamber without requiring user manual intervention for emptying, thereby improving user comfort and reducing the risk of pressure ulcers and spills

Inventive Principle:

Principle #25Self-service

2Reliability

If urinary catheters are used for fluid collection, then fluid collection capability is provided, but user comfort and health are deteriorated due to discomfort, pain, and urinary tract infections

Engineering Contradiction:

Improvefluid collection capabilityVSAvoiduser comfort and health

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the fluid collection function from the body through a removable collection chamber that can be detached from the pump unit. This allows the chamber to be emptied by pumping fluid into a separate storage container, eliminating the need for continuous catheterization and reducing the risk of urinary tract infections

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system replaces the invasive catheter mechanism with a non-invasive collection chamber that captures fluid and allows for automated removal via pump. This substitution eliminates the discomfort and pain associated with catheters while maintaining effective fluid collection

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If manual fluid removal methods are used, then fluid collection is achieved, but productivity and efficiency are reduced due to time-consuming processes and caregiver dependency

Engineering Contradiction:

Improvefluid collectionVSAvoidfluid removal efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The pump unit enables users to independently perform fluid removal without requiring caregiver assistance. The automated pumping mechanism eliminates manual emptying tasks, significantly improving productivity and reducing the time required for fluid removal compared to traditional manual methods

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces manual fluid removal mechanics with an automated pump-driven system. The pump creates negative pressure to automatically draw fluid from the collection chamber through the conduit to the storage container, dramatically improving fluid removal efficiency and eliminating caregiver dependency

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
