Tilted Holster Medical Cart for Secure Component Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical carts with horizontal or hole-like holsters are not ergonomic, cause damage when moved, and are difficult to use, as they lack secure and convenient storage solutions for medical components.
Innovation Solution
A medical cart apparatus with a tilted holster that provides ergonomic storage, featuring a back wall, side cut-outs, a lip, and a bottom surface tilted at an angle (55-95 cm and 5-55°) for easy access and visibility, along with circular padding and durable coating, to securely hold components like patient interface units and medical devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a horizontal holster is used to store components, then the cart structure is simple, but the holster causes damage to elements when the cart is moved or contacts surroundings
Solution Approach 1:
The holster is tilted at an angle (e.g., 45 degrees) relative to the horizontal plane, changing the storage dimension from horizontal to inclined. This angular orientation prevents elements from falling outward during cart movement while maintaining structural simplicity, directly resolving the contradiction between protection and complexity.
2Ease of operation
If a horizontal or hole-like holster is used, then the holster structure is simple, but it is not ergonomic or easy to place elements in the holster
Solution Approach 1:
The inclined design of the holster creates a natural sliding surface that guides elements into the holster during placement and allows easy retrieval by sliding. This angular geometry improves ergonomics without adding complex mechanisms, resolving the contradiction between ease of operation and structural simplicity.
Solution Approach 2:
The holster incorporates a curved bottom surface that conforms to the shape of stored elements, providing ergonomic contact points and facilitating easy placement and removal. The curved geometry enhances user interaction while maintaining a simple overall structure.
3Reliability
If a hanging holster on the side of the cart is used, then storage is accessible, but a user, wall or other object may hit elements on the cart and cause damage
Solution Approach 1:
The holster is positioned at an elevated height and tilted at an angle, moving the storage location away from the vulnerable side area. This elevated inclined positioning protects elements from being hit by users or objects while maintaining accessibility through the inclined design that facilitates easy placement and retrieval.
4Ease of operation
If a tilted holster is used to improve ergonomics and protection, then element storage is secure and convenient, but the holster requires specific dimensional parameters to optimize ergonomic access
Solution Approach 1:
The holster is designed with specific dimensional parameters including a tilt angle of approximately 45 degrees, elevation height between 55-95 cm, and specific width and depth dimensions. These optimized parameters create ergonomic access while preventing elements from falling out, resolving the contradiction between ease of operation and dimensional complexity through carefully selected values rather than adjustable mechanisms.

AI summary
A medical cart apparatus includes at least one component and at least one holster that is tilted with respect to a horizontal plane and is configured to hold or store the at least one component. The medical cart apparatus is ergonomic and conveniently and securely stores elements in the cart. The holster is configured as a storage area, holder, or receptacle, and the holster has a back wall, at least one side, at least one side cut-out, a lip at an entrance of the holster, and a bottom surface that is tilted at the angle with respect to the horizontal plane. The side cut-outs of the holster provide visibility by showing whether a component is in the holster or not, and provide accessibility by facilitating or allowing easy insertion and easy takeout of the at least one component from the holster.
