Solution Overview
Problem
Existing slatted frames with alternately arranged slats on two levels require a specially trained frame and can have uneven support due to the strength of the load, leading to gaps between end caps that negatively affect support.
Innovation Solution
A slatted frame design using alternating first and second end caps with different numbers of recording openings on each level, allowing the first slats to lie flat initially and interlock with second slats under load, ensuring symmetrical support across the entire lying surface without gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specially designed frame is used to achieve alternating slats on two levels, then support effect is improved, but device complexity increases
Solution Approach 1:
The frame is divided into standard modular components with end caps that have differentiated receiving openings. The first end caps have receiving openings only in the first level, while second end caps have receiving openings in both levels, allowing alternating slat arrangement through modular assembly rather than complex integrated design.
Solution Approach 2:
The end caps serve multiple functions: they attach slats to the frame, provide structural support, and through their differentiated receiving opening configurations, enable the alternating two-level slat arrangement. This multi-functionality eliminates the need for specially designed complex frames.
2Ease of manufacture
If identical end caps are used, then manufacturing is simplified, but load distribution becomes uneven causing gaps between end caps
Solution Approach 1:
The end caps are intentionally designed asymmetrically with respect to receiving opening configuration. First end caps have receiving openings only in the first level, while second end caps have receiving openings in both levels. This asymmetric design creates symmetrical load distribution across the frame when alternating end caps are used, preventing gaps between end caps under load.
3Adaptability or versatility
If first slats are positioned above spaces between second slats, then support adaptability to load is improved, but manufacturing precision requirements increase
Solution Approach 1:
The slat system transitions from a static single-level arrangement to a dynamic two-level alternating arrangement. When the frame is unloaded, the mattress rests on the upper first slats. When loaded, the first slats are pressed down toward the second slats, which then also engage to provide support. This dynamic engagement provides adaptability while the standardized receiving openings maintain manufacturing precision requirements.

AI summary
In a slatted frame (1) comprising a frame (2) and first and second slats indirectly attached to the frame (2) in an alternating manner, wherein the first slats are arranged in a first plane (8) and the second slats in a second plane (9), wherein the first slats are arranged above spaces between the second slats, it is proposed that the slats are attached to the frame (2) by means of first and second end caps (3, 4), that the end caps (3, 4) are arranged alternately on two sides of the frame (2) from a foot end (5) of the frame (2) to a head end (6) of the frame (2), that each first end cap (3) has one more receiving opening (7) in the first plane (8) than in the second plane (9) and each second end cap (4) has one fewer receiving opening (7) in the first plane (8) than in the second plane (8).
