Elastic Bed Ring Frame with Transverse and Longitudinal Folding Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elastic beds have inconvenient disassembly of mesh fabric and occupy large volume, making them difficult to fold and store.
Innovation Solution
The elastic bed features a ring frame with transverse and longitudinal folding interfaces, detachable mesh fabric, and a support leg interface with a T-shaped groove for easy assembly and disassembly, along with adhesive tape sets for adjustable tension, allowing for compact folding and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mesh fabric is tied to the hook by riveting or ropes, then the mesh fabric is securely fixed, but it becomes difficult to disassemble
Solution Approach 1:
The connection system is segmented into separate components: the hook structure on the connecting frame and the corresponding loop or attachment mechanism on the mesh fabric. This segmentation allows the mesh fabric to be easily attached and detached while maintaining secure fixation during use, resolving the contradiction between reliability and ease of operation.
2Stability of the object's composition
If the elastic bed is designed with a fixed structure, then it provides stable support, but it occupies large volume and is difficult to fold and store
Solution Approach 1:
The connecting frames are designed with dynamic hinge connections that allow the structure to transition between an extended stable configuration during use and a compact folded configuration for storage. The hinges enable controlled movement while maintaining structural integrity, resolving the contradiction between stability and compactness.
Solution Approach 2:
The connecting frames are designed to nest within each other when folded, with inner frames positioned inside outer frames. This nesting arrangement minimizes the storage volume while maintaining the ability to provide stable support when deployed, effectively resolving the contradiction between structural stability and compact storage.
3Strength
If the support leg interface uses a complex connection mechanism, then it provides strong clamping force, but it becomes difficult to assemble and disassemble
Solution Approach 1:
The support leg interface is segmented into a T-shaped groove in the connecting frame and a corresponding T-shaped clamping portion on the support leg. This simple geometric segmentation provides effective clamping force through the shape complementarity while allowing easy insertion and removal, resolving the contradiction between strength and ease of operation.

AI summary
An elastic bed includes: a ring frame, comprised of four connecting frames that are pin-connected in sequence, where two adjacent connecting frames can be folded in half relative to the other two connecting frames through a transverse folding interface, and two adjacent connecting frames can be folded in half through a longitudinal folding interface; a mesh fabric, disposed inside the ring frame and detachably connected to the ring frame.
