Urine Collector With Elastic Cup Cover and Suction System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing urine collectors for male patients with limited mobility are uncomfortable due to complex and large wearing assemblies, leading to discomfort and increased risk of urine leakage, and often require frequent diaper changes which can lead to bacterial growth and health issues.
Innovation Solution
A urine collector with a wearable assembly comprising a cup body, elastic cup cover, suction hoses, and liquid sensors controlled by an electronic module that generates negative pressure to collect urine, reducing the need for additional fixation and improving airtightness, while allowing for easy detachment and cleaning of the urine collecting container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex wearing assembly structure is used to improve airtightness, then urine leakage is reduced, but user comfort deteriorates due to larger size and complexity
Solution Approach 1:
The wearing assembly is divided into separate components: cup body, cup cover, and wearable assembly. The cup cover can be detached from the cup body, allowing for simplified wearing process while maintaining airtightness when connected. This segmentation enables the system to be simple during wearing and only complex when fully assembled for optimal sealing.
Solution Approach 2:
The cup cover is made of elastic material that can flexibly adapt to the user's anatomy. This flexible design provides a good seal without requiring a complex rigid structure, thereby maintaining airtightness while improving comfort and reducing the overall size of the wearing assembly.
2Object-affected harmful factors
If frequent diaper changes are implemented to maintain hygiene, then bacterial growth is reduced, but user convenience deteriorates due to frequent interruptions
Solution Approach 1:
The mechanical absorption process of diapers is replaced with an active suction system using suction pumps. Urine is automatically pumped away from the wearable assembly into a collecting container, preventing urine accumulation that would lead to bacterial growth. This eliminates the need for frequent changes while maintaining hygiene.
Solution Approach 2:
The suction pumps operate continuously or periodically to maintain a dry environment in the wearable assembly. This continuous removal of urine ensures hygienic conditions are maintained without interruption to the user's daily activities, unlike discrete diaper changes.
3Productivity
If catheters are used to assist urination, then urine collection is improved, but user comfort deteriorates due to pain and discomfort
Solution Approach 1:
The system uses liquid sensors that automatically detect the presence of urine and trigger the suction pumps without user intervention. This self-service mechanism eliminates the need for catheters while maintaining efficient urine collection, as the system activates itself when needed.
Solution Approach 2:
Liquid sensors provide real-time feedback about urine presence to the control system, which then activates the suction pumps. This feedback loop enables automatic urine collection without requiring invasive catheters, improving comfort while maintaining collection efficiency.
