Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spring mattresses face challenges in transportation and handling due to large bulk, high costs, and difficulties in disassembly and assembly, leading to increased labor and potential damage or deformation.
Innovation Solution
A packaging supporting frame comprising transverse and longitudinal frames with rollers and bottom supporting frames, allowing for the disassembly of a spring mattress into separate components that are packaged in independent containers, which are then stacked on the frame for compact transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If spring mattresses are disassembled into separate components for shipping, then transportation cost and storage space are reduced, but assembly time and handling complexity increase
Solution Approach 1:
The packaging frame is pre-assembled with all necessary components (longitudinal frames, transverse frames, bottom supporting frames, buckling structures) before the mattress components are packaged. This preliminary preparation of the packaging structure enables rapid assembly at the destination without requiring complex on-site construction, thus reducing assembly time while maintaining the volume reduction benefits of disassembled shipping
Solution Approach 2:
The mattress is divided into separate components (spring units, cushioning layers, bottom plates) that are packaged individually in separate containers. These segmented components are then stacked on the packaging frame using standardized interfaces, allowing for reduced packaging volume during transport while enabling straightforward reassembly through simple connection operations
2Ease of operation
If spring mattresses are disassembled into separate components, then transportation convenience is improved, but difficulty in moving and handling increases
Solution Approach 1:
The packaging frame serves multiple functions: it acts as a support structure during packaging, a stacking platform for multiple mattress components, a transportation unit that can be moved as one assembly, and an assembly guide for reconstitution. This multi-functionality simplifies handling operations throughout the supply chain while maintaining the transportation convenience benefits of disassembled components
Solution Approach 2:
Multiple separate mattress components (spring units, cushioning layers, bottom plates) are combined into a single integrated packaged unit by stacking them on the packaging frame and securing them together. This merging reduces handling complexity by allowing one packaged unit to be moved and managed as a single entity despite containing multiple discrete components
3Volume of moving object
If spring mattresses are packaged in separate containers, then storage space efficiency is improved, but risk of damage and deformation increases
Solution Approach 1:
Each mattress component is individually packaged in its own container with appropriate cushioning and protection before being placed on the packaging frame. This preliminary protection prevents damage during handling and stacking operations, while the modular container design maintains space efficiency. The buckling structures provide additional mechanical support to prevent deformation during transport
4Volume of moving object
If longitudinal frames are folded inward for compact storage, then storage volume is reduced, but structural stability during use is compromised
Solution Approach 1:
The longitudinal frames are designed with folding capability that allows them to transition between a stable extended configuration during packaging and storage, and a compact folded configuration for space-efficient storage. The rotatable connections and buckling structures provide mechanical stability in the extended state while enabling easy transformation to the compact state, thus achieving both structural stability and volume reduction

AI summary
A packaging supporting frame for a spring mattress includes two transverse frames, two longitudinal frames, and rollers. Each of one or more bottom supporting frames is configured to be rotated to form an angle between 0°and 90°with a corresponding one of the two transverse frames. When the one or more bottom supporting frames are rotated perpendicular to the two transverse frames, two ends of each of the one or more bottom supporting frames are respectively connected to the two longitudinal frames. A length of each of the two transverse frames in a transverse direction is greater than or equal to twice a length of each of the two longitudinal frames in a longitudinal direction, and the rollers are arranged at the bottoms of the two transverse frames or bottoms of the two longitudinal frames.
