Solution Overview

Problem

Conventional urine collection devices lack adaptability in size and geometry, leading to instability and mobility issues when used by individuals with varying anatomical features, resulting in ineffective securement between the legs.

Innovation Solution

A sizing device is introduced that can be secured to the urine collection device, providing additional length and width to improve securement, featuring a body with a recess that complements the device's distal portion, allowing for enhanced stability and secure positioning between the legs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional urine collection device is used, then the device structure is simple, but the device lacks adaptability to different anatomical sizes resulting in poor securement stability

Engineering Contradiction:
Improveadaptability to different anatomical sizesVSAvoiddevice structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sizing device is designed to be attached to the distal end of the urine collection device, with the recess receiving and securing the urine collection device within it. This nested configuration allows the sizing device to accommodate different anatomical sizes while maintaining a relatively simple overall structure, as the sizing device acts as an outer shell that can be fitted onto standard urine collection devices.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the urine collection device is made larger to accommodate different anatomical sizes, then adaptability improves, but the device length increases

Engineering Contradiction:
Improvesecurement adaptabilityVSAvoiddevice length
Core Design Contradiction:
Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The system is divided into two separate components: the original urine collection device and the separate sizing device. This segmentation allows the sizing device to provide the necessary adaptability and securement features without requiring the entire device to be larger. The sizing device can be attached only when needed, adding length only to the extent necessary for securement rather than increasing the length of the entire urine collection system.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If the urine collection device is made larger to improve securement, then stability improves, but the device volume increases

Engineering Contradiction:
Improvesecurement stabilityVSAvoiddevice volume
Core Design Contradiction:
Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The sizing device with its recess receives and secures the urine collection device, creating a nested configuration that provides stability through the larger outer dimensions of the sizing device without requiring the entire system to have increased volume. The stabilizing features are concentrated in the sizing device portion that contacts the patient's anatomy.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

By separating the stabilizing/securement function into a distinct sizing device component, the volume increase is localized only to the sizing device rather than the entire urine collection system. This allows stability to be improved without proportionally increasing the total device volume.

Inventive Principle:
Principle #1Segmentation

AI summary

Examples relate to devices, systems, and methods for fluid collection such as urine. A urine collection system (100) includes a urine collection device (102) and a sizing device (150) secured or securable to the urine collection device (100). The sizing device (150) includes a body (152) and a recess (185). The body (152) has a distal end (160) and an attachment end (155) distal to the distal end (160). The attachment end (155) defines an opening (180), and the recess (185) extends into the body (152) from the opening (180). The recess (185) is sized and dimensioned to receive a portion of the urine collection device (102) and secure the sizing device (150) to the urine collection device (102).
