Motorized functional fitting for a base of a box spring bed or of a platform bed, or for a slatted bed base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized functional fittings for bed frames are limited by the need for multiple variants due to varying bed lengths, leading to high storage costs and inefficient transport, and lack ergonomic adjustments for upright positions.
Innovation Solution
A motorized functional fitting with a symmetrical, V- or Y-shaped support frame centered on the bed frame, allowing a single drive unit to control the headrest and backrest movements independently or synchronously, and a split longitudinal beam design for efficient force transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional longitudinal beam design is used, then the bed frame can support the required loads, but multiple variants are needed for different bed lengths, increasing storage costs and transport inefficiency
Solution Approach 1:
The functional fitting is designed as a universal component that can be used with bed frames of different lengths and configurations. The symmetrical V- or Y-shaped support frame with centrally positioned longitudinal beam allows the same fitting to accommodate various bed widths, eliminating the need for multiple variants and reducing storage and transport costs.
2Force
If the headrest and backrest are connected to the longitudinal beam, then the lifting force is reduced, but the power consumption increases
Solution Approach 1:
The headrest and backrest are connected to the symmetrical V- or Y-shaped support frame rather than directly to the longitudinal beam. This structural arrangement changes the dimension of force transmission, allowing the lifting force to be more effectively distributed and reducing the power consumption of the motor while maintaining the required lifting capability.
3Adaptability or versatility
If a symmetrical V- or Y-shaped support frame is used, then a single fitting accommodates various bed widths, but the structural complexity increases
Solution Approach 1:
While the overall support frame is symmetrical, the connection points and linkage mechanisms incorporate asymmetric elements that allow adaptation to different bed widths. The longitudinal beam is positioned centrally but connects to asymmetrically arranged upper arms and linkages, enabling the same fitting structure to accommodate various bed configurations without requiring multiple variants.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables a single fitting to accommodate various bed widths, reduces storage and transport costs, and provides ergonomic adjustments for comfortable upright positions with reduced power consumption.
Implementation Method 1
A linear drive extending between the longitudinal beam and the erection frame converts the rotational movement of an electric motor into the translational movement of a lifting tube
Implementation Method 2
the erection frame can be continuously moved from a lowered rest position (in a lying position) to an upright position
