Disposable Bedpan Lid Structure for Stacking and Weight Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable bedpans with lids lack efficient stacking, weight support, and economical storage solutions, and often require special tools for configuration and closure.
Innovation Solution
A disposable bedpan with a symmetrical design featuring a base, sidewall with lateral supports, a top ridge, and a cover with a U-shaped ridge that connects via a hinge, allowing for easy stacking and closure without tools, using biodegradable materials for cost-effectiveness and environmental sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a disposable bedpan with lid is designed without stacking features, then ease of manufacture is improved, but storage efficiency deteriorates
Solution Approach 1:
The bedpan is designed with an open bottom configuration that allows one bedpan to be nested inside another, with the lid of one bedpan fitting over the base of another. This nesting arrangement enables compact vertical stacking for storage and transport, dramatically reducing the space required to store multiple disposable bedpans while maintaining the simplicity of the disposable design.
2Device complexity
If a disposable bedpan is designed without weight support features, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The bedpan is divided into distinct functional segments: a base portion for waste collection, a lateral support structure with weight-bearing surfaces, and a lid portion. The lateral supports include specific structural features like flanges and engagement surfaces that provide weight support capability. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity suitable for disposable use.
3Manufacturing precision
If a disposable bedpan requires special tools for configuration and closure, then manufacturing precision can be improved, but ease of operation deteriorates
Solution Approach 1:
The bedpan incorporates self-configuring features including snap-fit connections, self-aligning ridges and grooves, and automatic sealing mechanisms that engage when the lid is placed on the base. These features allow the bedpan to be assembled and sealed by hand without requiring special tools, while still achieving precise alignment and secure closure through the inherent mechanical design of the components.

AI summary
A disposable bedpan with lid, having a bedpan with a base and a sidewall having at least one lateral support. The bedpan further has a top ridge and a front ridge. The bedpan further has a front top cavity defined between the top ridge and the front ridge. A cover has a cover base and a u-shaped cover base ridge. The u-shaped cover base ridge is inserted into the front top cavity when the cover mounts upon the bedpan. The cover is connected to the bedpan by a hinge. A lid has a lid panel and is connected to the bedpan by a lid hinge. The bedpan having the cover and lid are for a single use and are disposable. A plurality of the bedpan having the cover and the lid are stackable upon one another. The bedpan having the cover and the lid collects waste.
