Slatted Frame Adapter Mount for Stable Motor-Pivoted Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slatted frames face stability issues due to moment loads on adapter elements when the back and leg sections are pivoted, leading to potential material failure and reduced stability.
Innovation Solution
The adapter element is firmly connected to the longitudinal part via two spaced-apart mounting bearings, with its carrier receptacle provided eccentrically relative to these bearings, reducing one-sided moment loads and enhancing stability through offset support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the back and leg sections are made motor-pivotable to enable adjusted lying positions, then the adaptability and comfort of the slatted frame is improved, but the moment load on the adapter elements increases leading to potential material failure and reduced stability
Solution Approach 1:
The adapter element is pre-designed with an eccentric carrier receptacle position relative to the mounting bearings, creating an offset support that proactively compensates for moment loads before they occur during pivoting operations
Solution Approach 2:
The carrier receptacle is positioned eccentrically (offset by a specific distance) relative to the mounting bearings, changing the geometric parameter of the adapter element to reduce the lever arm and consequently the moment load on the bearings during pivoting
2Stability of the object's composition
If the adapter element is firmly connected via two spaced-apart mounting bearings to improve stability, then the resistance against tipping is improved, but the device complexity increases
Solution Approach 1:
The connection between the adapter element and longitudinal part is divided into two separate mounting bearings spaced apart from each other, distributing the load and improving stability against tipping while maintaining a relatively simple structural implementation
3Reliability
If the carrier receptacle is positioned eccentrically to reduce one-sided moment load, then the reliability under pivot load is improved, but the manufacturing precision requirements increase
Solution Approach 1:
A specific eccentric offset distance is defined for the carrier receptacle position, transforming the design into a parameter-based solution that can be manufactured with standard tolerances while achieving the desired moment load reduction effect

AI summary
The frame i.e. slatted frame (1), has individual spring elements (3), and a slat-shaped carrier (4) for fixing the elements. A longitudinal part (11) has a drive (10), a middle part (5) and side parts (6, 7) that are supported at the middle part. The drive is connected with the side parts. An adapter element (12) is fastened to the longitudinal part, and forms a carrier retainer (13). The adapter element is fixedly connected with the longitudinal part over fastening bearings (14, 15) that are arranged at a distance to each other, where the retainer is arranged opposite to the bearings.
