Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpacks and suitcases for medical equipment face challenges in easy cleaning and disinfection, and they often lack a secure and precise arrangement of equipment, leading to potential slippage and mixing of items.
Innovation Solution
A backpack or suitcase design featuring a lower and upper shell with inner and outer layers, where magnetic coupling elements are embedded between the layers, allowing for secure fixation of medical devices and instruments without visible protrusions, and facilitating easy cleaning and disinfection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If magnetic fastening elements are freely movable in hollow spaces formed by sewn or welded layers, then the magnetic elements can be positioned flexibly, but the equipment cannot be securely fixed and the interior layers become dirt-prone and difficult to clean
Solution Approach 1:
The patent divides the shell into an outer layer and an inner layer, with the magnetic coupling elements embedded in recesses of the inner layer. This segmentation allows the magnetic elements to be fixed in specific positions within the inner layer while maintaining the flexibility to position equipment at different locations on the outer surface, resolving the contradiction between flexibility and secure fixation.
Solution Approach 2:
The magnetic coupling elements are pre-embedded in the inner layer during manufacturing, creating a stable foundation before equipment is stored. This preliminary action ensures that the magnetic elements are securely positioned and cannot shift, providing reliable fixation for equipment while maintaining ease of cleaning since the magnetic elements are already in place.
2Adaptability or versatility
If magnetic fastening elements are freely movable in hollow spaces, then positioning flexibility is improved, but cleaning and disinfection becomes difficult
Solution Approach 1:
By separating the magnetic coupling elements and embedding them in the inner layer with recesses, the patent creates a smooth outer surface without protruding magnetic elements. This segmentation allows the outer layer to be easily cleaned and disinfected while the magnetic elements remain securely positioned in the inner layer, resolving the contradiction between positioning flexibility and ease of cleaning.
3Ease of manufacture
If magnetic coupling elements are flush-mounted in recesses between inner and outer layers, then cleaning ease is improved and equipment security is enhanced, but the complexity of manufacturing increases
Solution Approach 1:
The patent combines the magnetic coupling elements with the inner layer structure by embedding them in recesses during the manufacturing process. This merging of the magnetic elements into the layer structure eliminates the need for separate mounting steps and reduces overall device complexity while achieving secure fixation and ease of cleaning.
Solution Approach 2:
The inner layer serves multiple functions: it provides structural support, contains the magnetic coupling elements in recesses, and creates a smooth outer surface for easy cleaning. This multi-functionality reduces the need for additional components, simplifying the overall device while achieving the desired cleaning ease and equipment security.
