Symmetrical Incontinence Device with Secondary Access Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing male urinary incontinence devices are bulky and inconvenient for lighter incontinence cases, as they are designed for medium to high incontinence and have large urine collection bags, making them uncomfortable and difficult to apply correctly.
Innovation Solution
A lightweight, discreet male urinary incontinence device with a smaller urine capacity (100-300 ml) featuring a symmetrical design with a through-going inlet opening and a secondary access opening for easy application and urination, incorporating a flexible cuff member and an absorbent element, allowing for easy inspection or exchange, and a hinged flap for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing male urinary incontinence devices are designed for medium to high incontinence with large urine collection bags, then they can handle higher urine volumes, but they become bulky and inconvenient for lighter incontinence cases
Solution Approach 1:
The patent applies parameter changes by designing a device with a reduced urine collection capacity (100-300 ml) compared to existing devices designed for medium to high incontinence. This parameter change in capacity directly reduces the overall device volume and bulkiness, making it suitable for lighter incontinence cases while maintaining adequate functionality for the target user group.
2Quantity of substance
If existing devices have large urine collection bags, then they can accommodate higher incontinence volumes, but they become difficult to apply correctly and comfortably
Solution Approach 1:
By reducing the urine collection capacity parameter to 100-300 ml, the device becomes smaller and more manageable, directly improving application ease. The smaller scale allows for more precise positioning and fitting on the penis, making the application process simpler and more comfortable for users with lighter incontinence needs.
3Ease of operation
If the device uses a symmetrical design with aligned openings, then it provides easy application and urination access, but it requires precise positioning of components
Solution Approach 1:
The patent actually employs symmetry as its design principle rather than asymmetry. The symmetrical design with the through-going inlet opening and second opening aligned along the longitudinal central axis provides ease of application and urination access. The manufacturing precision requirement is managed through the modular construction and standardized component interfaces described in the patent.

AI summary
A male urinary incontinence device (10) comprising a proximal wall (20) and a distal wall (30) being sealed together at the periphery to form an inner cavity (70), the proximal wall comprises a through-going inlet opening (25) through which a penis can be entered, the inner cavity adapted to contain at least a part of the penis, and wherein the distal wall comprises a second opening (35) configured for allowing access to the inner cavity, the through-going inlet opening comprises a circular shape, and where the through-going inlet opening (25) is positioned symmetrically at a longitudinal central axis X defined by a line of symmetry in radial direction of the device.
