Transfer Bed Conveyor Belt Assembly for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conveyor cloth belt in existing medical transfer beds is difficult to clean due to direct contact with patients, leading to contamination from blood stains and drugs, and is inconvenient to disassemble.
Innovation Solution
A medical transfer bed design featuring a detachable driving roller and conveyor cloth belt system, with a clutch mechanism allowing easy separation and replacement, and a buckling plate for convenient cleaning, along with a synchronization piece for stable mounting and a limiting roller group for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the conveyor cloth belt is made integral with the bed board structure, then the structural strength is improved, but the ease of cleaning and maintenance deteriorates
Solution Approach 1:
The conveyor cloth belt is segmented from the bed board structure through detachable connection mechanisms (clamps, fasteners, or release mechanisms). This allows the cloth belt to be separated into independent removable segments while the bed board retains its structural integrity, enabling easy cleaning and replacement of the cloth belt without compromising the overall structural strength.
2Reliability
If the conveyor roller is permanently fixed to the mounting base, then the reliability of patient transfer is improved, but the ease of operation for cleaning deteriorates
Solution Approach 1:
The conveyor roller transitions from a permanently fixed state to a dynamically adjustable state, incorporating detachable connections that allow it to be easily removed from the mounting base. During patient transfer, the roller is securely engaged for reliable operation; during cleaning, it can be quickly detached and removed, providing dynamic adaptability between operational reliability and cleaning convenience.
3Reliability
If the driving roller is firmly connected to the driving mechanism, then the transmission reliability is improved, but the ease of disassembly for replacement deteriorates
Solution Approach 1:
The driving roller incorporates preliminary detachable connection features (such as quick-release mechanisms, clamps, or standardized mounting interfaces) that enable rapid disassembly and replacement. These pre-designed connection points maintain firm engagement during operation for reliable power transmission, while allowing quick separation when replacement is needed, eliminating the need for complex disassembly procedures.
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
Facilitates easy cleaning and replacement of the conveyor cloth belt, improves stability during patient transfer, and enhances operational convenience by simplifying the assembly and disassembly process.
Implementation Method 1
the patient is driven to the bed board by means of friction between the conveyor cloth belt and the patient's body
