Removable Casing for Stretcher Trolley Chassis Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Stretcher trolleys in hospital environments are difficult to disinfect due to complex frame structures and hard-to-reach areas, making thorough cleaning time-consuming and prone to infection risks.
Innovation Solution
A removable casing with mounting means covers the upper face of the stretcher trolley frame, protecting it from soiling and facilitating easy disassembly for cleaning, while a protective bellows covers the lifting arm to prevent fluid spread, and the casing is made of antibacterial material to reduce infection risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame structure is complex to provide necessary functionality, then the stretcher trolley can perform required operations, but cleaning becomes time-consuming and difficult
Solution Approach 1:
The frame is divided into modular components that can be easily detached from each other. The lifting arm separates from the base structure, and the lying surface can be removed independently. This segmentation allows each component to be quickly accessed and cleaned separately, dramatically reducing overall cleaning time while maintaining full frame functionality.
Solution Approach 2:
The lifting arm is extracted as a separate removable component from the frame structure. It can be completely detached and removed from the stretcher trolley, allowing thorough cleaning of both the lifting arm itself and the frame area where it was mounted. This extraction eliminates hard-to-reach areas that would otherwise be difficult to clean.
2Stability of the object's composition
If the frame has multiple elements and angles for structural integrity, then the stretcher is stable, but cleaning access becomes difficult
Solution Approach 1:
The lifting arm incorporates a telescopic mechanism that allows it to extend and retract. When retracted, the lifting arm can be easily accessed for cleaning from all angles. The dynamic nature of this component allows it to be positioned in different configurations during cleaning operations, making previously inaccessible areas reachable while maintaining structural stability during use.
3Reliability
If the stretcher trolley is designed for thorough disinfection, then infection risk is reduced, but cleaning operations become lengthy
Solution Approach 1:
The frame components are designed with pre-attached cleaning ports and removable sections that are easily accessible before the cleaning process begins. The lifting arm and lying surface are configured to be quickly detached and positioned for optimal cleaning access, eliminating the need for lengthy preparation time while ensuring complete disinfection coverage of all surfaces.
4Volume of moving object
If the frame elements are closely arranged for compact design, then space is optimized, but cleaning tools cannot reach all areas
Solution Approach 1:
The frame is segmented into modular sections with standardized connection points. These segments can be quickly separated to create cleaning access pathways without requiring excessive space. The compact design is maintained when components are assembled, but during cleaning they can be separated to allow tool access to previously unreachable areas, then reassembled to restore compact configuration.
