Solution Overview

Problem

Existing urine collector devices for male patients with urinary incontinence or bedridden individuals are cumbersome, require assistance, and lack privacy, causing discomfort for both patients and caregivers due to the need for manual handling and cleaning, especially at night.

Innovation Solution

A urine collector device featuring a leak-tight, impermeable elongated bag receptacle with three coupling parts made of different materials for secure attachment to the body, including a soft silicone part for the penis, a stiffer central part with a membrane, and a third part for the receptacle, secured with belts around the waist and scrotum, ensuring complete leak-tightness and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If bedpan- or bottle-type urine collector devices are used, then urine collection is achieved, but the patient requires assistance from another person and lacks privacy

Engineering Contradiction:
Improveindependence in urine collectionVSAvoidneed for manual handling
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device enables patients to independently collect urine without requiring assistance from caregivers. The anatomical cup fits directly onto the penis and the collection bag can be attached and detached by the patient themselves, eliminating the need for others to place and remove the container.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device is divided into separate functional components: an anatomical cup for collection, a connection piece for secure attachment, and a collection bag for storage. This segmentation allows each part to be optimized independently and simplifies the overall operation for the user.

Inventive Principle:
Principle #1Segmentation

2Reliability

If frequent manual handling and cleaning of urine collector devices is required, then hygiene is maintained, but it causes inconvenience and burden for both patient and caregiver

Engineering Contradiction:
Improvehygiene maintenanceVSAvoidtime for cleaning and handling
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The anatomical cup and connection piece are designed as disposable components that can be discarded after a single use, eliminating the need for cleaning and sterilization. Only the collection bag needs to be emptied and replaced, significantly reducing the time and effort required for maintenance.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Ease of manufacture

If a simple single-material receptacle is used, then manufacturing is simplified, but leak-tightness and secure attachment cannot be ensured

Engineering Contradiction:
Improvereceptacle fabricationVSAvoidleak-tightness
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The device uses different materials for different components: the anatomical cup is made of flexible silicone for comfort and seal, while the connection piece is made of rigid plastic for structural integrity and secure attachment. This composite approach ensures both leak-tightness and ease of manufacture.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

Each component is made from materials and with designs optimized for its specific function: the anatomical cup has a soft flexible material for comfort and sealing against the body, the connection piece has rigid structure for secure mechanical attachment, and the collection bag has impermeable material for urine containment.

Inventive Principle:
Principle #3Local quality

4Quantity of substance

If an elongated bag receptacle is used, then urine accumulation capacity is increased, but the device bulk and complexity increase

Engineering Contradiction:
Improveurine accumulation capacityVSAvoiddevice bulk
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The anatomical cup nests within the connection piece, which in turn connects to the collection bag. This nested arrangement minimizes the overall volume of the device when not in use and allows for compact storage while maintaining adequate urine accumulation capacity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The invention relates to a urine collector device (1) for use by men, comprising: an elongated impermeable bag receptacle (2), a proximal opening (12) at one end of the receptacle (2), into which the penis is inserted, a distal opening (13) in the receptacle (2) through which urine is discharged, and coupling means for coupling the receptacle (2) to the user, including: a first coupling part (3) with a proximal end closer to the abdomen, and a distal end, a first through hole (14) in part (3) for housing the base of the penis, a second coupling part (4) with a proximal end, a second through hole (15) in part (4), corresponding to hole (14), where the distal end of part (3) can be coupled at the proximal end of part (4) in a leak-tight manner due to the difference in stiffness, a third coupling part (5) which is stiffer than part (3) and can be connected to part (4) and to the receptacle (2) by means of form-fit closures, a third through hole (16) in part (5) corresponding to holes (14) and (15); and securing means for attaching the coupling means and the receptacle (2) to the user. The device can be positioned easily and reused, and has a reduced volume and improved sealing.
