Bedpan Cleaning Device Automatic Lid Opening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for bedpans with lids require manual removal and reinsertion of the lid, which is uncomfortable and not hygienic, necessitating improved handling and hygiene during the cleaning process.
Innovation Solution
A cleaning device equipped with an automatic opening device for the bedpan lid, allowing it to be lifted automatically when the door is closed, enabling the bedpan and lid to be cleaned together without manual lid removal, and featuring a support arm with a gripper to hold the lid handle and a support device for stabilization during cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal and reinsertion of the lid is required, then the cleaning device can be simpler in structure, but the handling becomes uncomfortable and hygiene conditions deteriorate
Solution Approach 1:
The opening device automatically performs the function of removing the lid from the bedpan without requiring manual intervention. The support arm with gripper self-activates when the door is closed, grasping the lid handle and pivoting the lid away from the bedpan body, thereby serving itself rather than requiring operator action.
Solution Approach 2:
The opening device is pre-positioned and pre-configured within the cleaning device. When the door is closed, the support arm and gripper are already in place to immediately grasp and open the lid, performing the opening action before the cleaning process begins and without requiring separate manual steps.
2Reliability
If the lid is manually removed before cleaning, then the cleaning process can be simpler, but hygiene conditions worsen due to direct contact with bedpan contents
Solution Approach 1:
The support arm and gripper act as intermediaries between the operator and the bedpan lid. Instead of the operator directly handling the lid and potentially contaminating themselves with bedpan contents, the automated mechanical system performs the lid manipulation, creating a hygienic barrier while maintaining operational simplicity.
3Manufacturing precision
If the lid is not opened automatically, then the device structure remains simple, but the cleaning effectiveness deteriorates as the bedpan contents cannot be properly accessed
Solution Approach 1:
The opening device is segmented into distinct functional components: the support arm for positioning, the gripper for grasping the lid handle, and the pivot mechanism for opening. This segmentation allows each component to perform its specific function efficiently while keeping the overall structure relatively simple and manufacturable.
