Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Double beds with integrated spring bases face transportation challenges due to their large size, and the separation of spring halves compromises lying comfort, leading to reduced suspension and comfort issues.
Innovation Solution
A foldable slat base design for double beds that can be halved in width for transport, featuring a one-piece construction with a folding joint and a foldable upholstery core overlay, ensuring continuous comfort without gaps or interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spring base is made as a one-piece construction for double beds, then the lying comfort is improved, but the transportation becomes difficult through narrow doors and stairwells
Solution Approach 1:
The spring base is divided into two separable halves that can be transported independently through narrow spaces. Each half contains a complete set of springs arranged to provide continuous support when joined, eliminating the transportation problem while maintaining the one-piece lying surface benefit
Solution Approach 2:
A connecting mechanism serves as an intermediary between the two spring base halves, allowing them to be joined during use to form a continuous support surface. This mediator enables the transition from separated transport state to unified functional state, resolving the contradiction between transportability and lying comfort
2Ease of operation
If the spring base is divided into two halves for transport, then the transportation is facilitated, but the lying comfort is impaired by the lack of spring effect in the frame area
Solution Approach 1:
The spring arrangement in each half is optimized to provide enhanced spring effect specifically in the frame area where the two halves meet. This local quality enhancement ensures that the joining region provides adequate support and comfort, eliminating the discomfort that would otherwise occur at the interface between halves
Solution Approach 2:
The two separate spring base halves are designed to merge seamlessly when joined, creating a unified support surface that functions as a continuous spring system. The merging design ensures no gap or discontinuity in the spring effect across the joining line, maintaining overall lying comfort
3Ease of operation
If the spring base is made foldable, then the transportation through narrow spaces is improved, but the structural complexity increases
Solution Approach 1:
The frame is segmented into two separable halves that can be folded or detached for transportation. This segmentation allows the structure to be compacted for narrow spaces while maintaining structural integrity when assembled, managing the complexity through functional separation rather than complex folding mechanisms
Solution Approach 2:
The spring base incorporates dynamic elements that allow it to transition between a compact folded state for transportation and an expanded functional state for use. This dynamic capability enables adaptability to different spatial requirements without requiring overly complex fixed structures

AI summary
The invention relates to a spring base for a double bed, z. B. Queen-size bed or French bed, with a folding frame. The spring base comprises an upholstery core (11; 24), a frame (10, 10'), an upholstery core overlay (20; 28) and an upholstered cover (1). The frame (10; 10') and the cushion core (11; 24) can be folded. The padding core support (20; 28) is designed in one piece, can be folded and essentially completely covers the padding core (11; 24).
