Retrofit kit for retrofitting a supporting device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for seating and lying furniture, such as mattresses, often lack the ability to be adjusted electrically, limiting user comfort and functionality.
Innovation Solution
A retrofit kit is provided that includes an auxiliary frame with pivoting frame parts connected via a Bowden cable system, allowing for electromotive adjustment by inserting it between the support device and upholstery, enabling adjustment of the mattress without increasing the overall height significantly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If an electromotive adjustment device is integrated into the support device, then electrical adjustability is achieved, but the overall height increases significantly
Solution Approach 1:
The adjustment device is nested within the hollow longitudinal beam of the base body. The drive motor, transmission elements, and adjustment mechanism are all accommodated inside the hollow profile structure, allowing the device to achieve electrical adjustability without increasing the overall height beyond the existing base body dimensions.
Solution Approach 2:
The invention utilizes the hollow internal space of the longitudinal beam in the vertical dimension to accommodate the adjustment mechanism. By placing components within the existing hollow profile rather than adding external components, the solution achieves automation functionality without increasing the external height envelope.
2Length of stationary object
If a hollow profile base body is used to accommodate the drive, then the overall height is reduced, but the structural strength may be compromised
Solution Approach 1:
The base body is constructed as a composite structure combining the hollow profile framework with integrated drive components. The hollow longitudinal beams provide structural support while accommodating the motor and transmission elements within, creating a composite system that maintains strength while minimizing height.
Solution Approach 2:
The base body is segmented into multiple hollow longitudinal beams that can independently support different components. This segmentation allows the structure to maintain strength through distributed support while the hollow interiors provide space for the adjustment mechanism without increasing overall height.
