Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of effective means to wash and dry the genitals, perineum, and anus of patients using bedpans in hospital settings, making the process difficult and unsanitary.
Innovation Solution
A bedpan system that integrates air, suction, and water connections to rinse and dry these areas, utilizing hospital sources and manual means, with a shell, liner, and waste disposal container for efficient waste removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional bedpan is used for waste collection, then waste can be captured, but there is no effective means to wash and dry the patient's genitals, perineum, and anus
Solution Approach 1:
The patent combines waste collection, washing, and drying functions into a single integrated bedpan system. The bedpan includes integrated nozzles for delivering water and air streams, merging multiple care functions into one device that can be positioned between the mattress and patient's buttocks.
Solution Approach 2:
The bedpan is designed as a multi-functional device that not only collects waste but also provides washing through water streams and drying through air streams. This universal device replaces the need for separate waste collection and hygiene care procedures.
2Reliability
If manual washing methods are used, then no special equipment is needed, but the process is difficult and unsanitary
Solution Approach 1:
The patent employs hydraulic principles by using water streams delivered through nozzles to rinse the patient's areas. It also employs pneumatic principles by using compressed air streams to dry the areas after washing, providing sanitary cleaning without complex electronic systems.
Solution Approach 2:
The system allows the patient to be washed and dried by the caregiver using the integrated streams, with the bedpan itself serving as the delivery mechanism. The design enables efficient self-contained hygiene care within the bedpan structure.
3Reliability
If a bedpan system with integrated washing and drying is created, then hygiene effectiveness improves, but the device complexity increases
Solution Approach 1:
The bedpan system is segmented into distinct functional components: waste collection portion, water delivery nozzles, air delivery nozzles, and positioning elements. This segmentation allows each component to perform its specific function efficiently while maintaining overall system manageability.
Solution Approach 2:
The patent uses water and air streams as intermediary substances to transfer cleaning and drying functions to the patient's areas. These intermediaries enable hygienic care without direct contact, reducing contamination risk while managing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively rinses and dries the genitals, perineum, and anus, providing a sanitary and efficient method for waste disposal.
Implementation Method 1
The suction connection is posited to remove bodily waste
Implementation Method 2
The air and water are directed onto genitals, perineum, and/or an anus of the user to rinse and dry these areas
