Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedpan devices are inadequate for obese individuals, as they do not effectively accommodate the scrotum and penis for urination, leading to discomfort and inefficiency.
Innovation Solution
A container with a specifically designed shape and dimensions, including a perimeter wall with an angled opening and a conduit for urine collection, allowing the scrotum and penis to rest comfortably within the receiving space, with a handle for support and a cap for easy urine disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing bedpan devices are used for obese individuals, then the device structure remains simple, but the device cannot effectively accommodate the scrotum and penis for urination
Solution Approach 1:
The bedpan device is divided into distinct functional segments: a receiving space for the scrotum and penis, a fluid communication channel for urine flow, and a discharge mechanism. This segmentation allows each part to be optimized for its specific function while maintaining overall adaptability without excessive complexity.
Solution Approach 2:
The device incorporates a three-dimensional receiving space with vertical walls that extend upward, creating multiple spatial dimensions for accommodation. This dimensional approach allows the device to accommodate larger anatomical structures of obese individuals without significantly increasing the overall footprint or structural complexity.
2Reliability
If a container with angled opening is used, then urine collection is effective without displacement, but the device requires more complex structural design
Solution Approach 1:
The container features a localized angled opening at the front portion, while the rest of the container maintains a simpler cylindrical or rounded structure. This local quality approach ensures effective urine collection at the critical discharge point without requiring complex structural modifications throughout the entire device.
Solution Approach 2:
The fluid communication channel acts as an intermediary element that connects the receiving space to the external environment. This channel ensures reliable urine collection and transport without requiring direct exposure or complex opening mechanisms, simplifying the overall structure while maintaining collection efficiency.
3Ease of operation
If the receiving space is designed to hold urine effectively, then urine disposal becomes easier, but the device size increases
Solution Approach 1:
The device incorporates a flexible or movable discharge mechanism that can be activated on demand. This dynamic approach allows the receiving space to be compact during storage and transport, then expand or open for urine disposal, providing ease of operation without permanently increasing device volume.
Solution Approach 2:
The discharge mechanism is nested within or integrated into the container structure, allowing the urine disposal system to be contained within the existing device volume. This nesting approach enables easy urine disposal functionality without significantly increasing the overall device size.

AI summary
A portable urinal assembly for receiving a scrotum and a penis of an obese person while urinating therein includes a container that has a bottom wall, a top wall and a perimeter wall that is attached to and extends between the top wall and the bottom wall such that a receiving space is formed therein. The receiving space holds urine. The perimeter wall has a front side, a back side, a first lateral side and a second lateral side. The top wall has an opening that extends therethrough. The top wall extends from the front side toward a central area of the top wall. The opening has a perimeter edge that is angled upwardly from the front side to the central area. A conduit is fluidly coupled to container and is in fluid communication with the receiving space. A cap is removably positioned on the conduit to close the conduit.
