Bedpan With Segmented Cavities And Living Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bedpans are uncomfortable, difficult to clean, and inefficient in separating and measuring liquid and solid waste, leading to increased risk of bedsores and maintenance challenges due to lack of splashguards and stackability, as well as opaque designs that obscure waste volume.
Innovation Solution
A bedpan with a main body featuring separate cavities for liquid and solid waste, a living hinge for splash protection and stacking, and a translucent thermoplastic material with graduations for accurate measurement, providing a comfortable seating area and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If bedpans are made with thin sides to reduce weight and manufacturing cost, then manufacturing cost decreases, but pressure distribution worsens leading to increased bedsores
Solution Approach 1:
The bedpan incorporates thickened side walls specifically in the seating area where pressure is applied, while other parts of the bedpan maintain standard thickness. This localized thickening improves pressure distribution and reduces bedsores without significantly increasing overall manufacturing cost or weight.
2Ease of manufacture
If bedpans use opaque material to reduce manufacturing cost, then manufacturing cost decreases, but waste volume detection worsens requiring manual inspection
Solution Approach 1:
The bedpan is manufactured with translucent material that allows visual detection of waste volume through the walls of the container. This eliminates the need for opaque materials while maintaining cost-effectiveness and enabling attendants to monitor waste levels without manual inspection.
3Device complexity
If bedpans have a single compartment for both liquid and solid waste to simplify structure, then device complexity decreases, but waste separation efficiency worsens requiring additional containers for measurement
Solution Approach 1:
The bedpan is divided into multiple compartments: a first compartment for solid waste and a second compartment for liquid waste. This segmentation enables automatic separation of waste types during use, eliminating the need for additional containers and manual separation procedures, thereby improving measurement efficiency while maintaining reasonable structural simplicity.
4Ease of operation
If bedpans include a splashguard to improve cleaning efficiency, then maintenance efficiency improves, but user comfort worsens due to sharp edges causing discomfort and bedsores
Solution Approach 1:
The splashguard is designed with curved, rounded edges instead of sharp angles. This curvature maintains the splashguard's functionality in preventing waste splatter and facilitating cleaning, while eliminating sharp edges that cause user discomfort and bedsores, thereby resolving the contradiction between cleaning efficiency and user comfort.

AI summary
A bedpan for collecting waste includes a seating area and a plurality of cavities. The seating area is located in a main body of the bedpan. The plurality of cavities is formed within the seating area and includes a first cavity for collecting liquid waste and a second cavity for collecting solid waste. The first cavity and the second cavity are separated by a divider.
