Foldable Medical Cart Seat With Plug-In Locking Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing children's medical carts with fixed seats occupy large spaces when not in use, are not adjustable for different body sizes, and lack stability and safety, especially for younger children, and are inconvenient to store and transport.
Innovation Solution
A foldable seat design with a hinge connection between a seat pan and back pan, combined with a connecting part and plug-in parts, ensures stability and safety by allowing the seat to be quickly folded and unfolded, and includes a joint bar with a hooking part for secure attachment to the cart body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed seat design is used, then the structure is simple, but the cart occupies large space when not in use and is not adjustable for different body sizes
Solution Approach 1:
The seat is divided into two main segments: the seat pan and the back pan, which are connected through a folding mechanism. This segmentation allows the seat to be folded into a compact configuration when not in use, reducing the space occupied by the cart, while maintaining structural simplicity through the use of straightforward hinge connections and support bars.
Solution Approach 2:
The seat incorporates a folding mechanism that transitions between a deployed state (providing seating) and a folded state (reducing space occupation). The dynamic capability allows the seat to adjust its configuration, enabling compact storage when not in use while maintaining ease of manufacture through simple hinge and support bar components.
2Ease of manufacture
If a fixed seat design is used, then the structure is simple, but the seat cannot be adjusted according to different body sizes and treatment needs
Solution Approach 1:
The folding mechanism enables the seat to transition between deployed and folded states, providing adaptability for different usage scenarios. When deployed, the seat pan and back pan form a stable seating structure; when folded, they compact to minimize space. This dynamic capability addresses adaptability needs while preserving structural simplicity through straightforward mechanical connections.
3Volume of moving object
If a detachable seat design is used, then the seat can be removed to increase loading space, but the seat stability and safety are reduced when carrying weight
Solution Approach 1:
The seat is segmented into the seat pan and back pan connected by a folding mechanism with support bars. This segmentation allows the seat to be folded compactly when not in use, increasing effective loading space, while the support bars maintain structural integrity and stability when the seat is deployed and carrying weight.
Solution Approach 2:
The folding mechanism provides dynamic adaptability: when folded, the seat compactly stores to maximize loading space; when deployed, the support bars engage to provide stable structural support for carrying weight. This dynamic behavior resolves the contradiction between loading space and seat stability.
4Ease of operation
If an expansion system with high position seat is used, then the cart is neat when folded and easy to carry, but the center of gravity is raised which is not conducive to overall stability
Solution Approach 1:
The folding mechanism enables the seat to transition between deployed and folded states. When folded, the seat pan and back pan collapse into a compact configuration that maintains a low center of gravity, ensuring overall cart stability while remaining neat and easy to carry. The dynamic folding capability allows the seat to achieve portability without compromising stability.
5Productivity
If the seat is folded and unfolded quickly, then space is saved and storage is simplified, but the connection stability must be maintained
Solution Approach 1:
The seat is segmented into the seat pan and back pan connected by a folding mechanism with support bars. This segmentation enables quick folding and unfolding actions while the support bars provide stable structural connections during both folded and deployed states, maintaining connection stability throughout the rapid transitions.
Solution Approach 2:
The folding mechanism is designed for rapid deployment and folding while incorporating support bars that ensure stable connections. The dynamic design allows quick transitions between states, and the support bars engage to maintain connection stability during and after the folding action, resolving the contradiction between folding speed and connection stability.
