Box Spring Frame Segmentation for Postal Transport and Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing box springs are difficult to transport and assemble due to their large components, making them costly to ship and time-consuming for customers to assemble, with standard postal services unable to handle the long frame parts.
Innovation Solution
A box spring design featuring U-shaped rail mounts for side rail elements and a central traverse, allowing for disassembly into parts under 80cm x 80cm x 120cm for cost-effective postal transport and simplified assembly, with threaded sleeves for easy attachment of feet to distribute loads stably.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the box spring is designed with long longitudinal bars (2m) for structural stability, then the structural stability is improved, but the transportability and ease of assembly deteriorate
Solution Approach 1:
The frame is divided into multiple segments: longitudinal bars (2m), transverse bars (1.2m), and connection elements. These segments can be transported separately via standard postal services and assembled by the customer into a stable box spring structure, resolving the contradiction between structural stability and transportability.
2Strength
If the box spring components are made large (2m longitudinal bars) to ensure structural integrity, then the structural integrity is improved, but the shipping cost and complexity increase
Solution Approach 1:
The frame structure is segmented into transportable components (longitudinal bars, transverse bars, connection elements) that fit within standard postal parcel dimensions (80cm x 80cm x 120cm). This allows shipping via standard postal services at lower cost while maintaining structural integrity through proper assembly of the segments.
3Stability of the object's composition
If the box spring is designed as a single assembled unit, then the structural stability is improved, but the ease of assembly and customer self-assembly deteriorates
Solution Approach 1:
The box spring is provided as segmented components (frame parts, suspension, mattress) that can be easily assembled by the customer using simple connection elements. The segmentation allows for straightforward assembly instructions and reduced assembly time while maintaining structural stability through the designed connection system.
4Ease of operation
If long frame parts (2m) are used to create a raised lying surface, then the comfort and ease of getting up is improved, but the transportability via standard postal services deteriorates
Solution Approach 1:
The frame is segmented into longitudinal bars (2m) that provide the necessary height for comfort, but these are combined with transverse bars (1.2m) and connection elements that can be transported separately within standard postal parcel size limits (80cm x 80cm x 120cm). This allows the final assembled structure to provide comfort while the components remain transportable.

AI summary
The invention relates to a box spring disassembled into its individual parts, comprising a suspension system and a frame (36) for supporting the suspension system, wherein the frame (36) comprises a right side rail (44a) and a left side rail (44b) opposite the right side rail (44b), wherein the frame (36) comprises a head rail (24) connecting the two side rails (44a,b) and a foot rail (25) connecting the two side rails (44a,b), and wherein the frame (36) comprises cross slats (72) for supporting the suspension system.Creating a box spring that can be delivered to the customer cost-effectively and that the customer can assemble easily without much effort is achieved by the fact that the right side rail (44a) is divided and consists of a first side rail element (48a) and a second side rail element (48b), and that the frame includes a right mounting fitting (50a) to which the first side rail element (48a) and the second side rail element (48b) can be attached, and/or that the left side rail (44b) is divided and consists of a first side rail element (48a) and a second side rail element (48b), and that the frame (36) includes a left mounting fitting (50b) to which the first side rail element (48a) and the second side rail element (48b) can be attached.
