Supporting frame for a piece of furniture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for securing lifting columns in furniture are time-consuming and cumbersome, particularly for those with box-shaped housings, as they require multiple components and tools for mounting, which complicates the assembly process.
Innovation Solution
A supporting frame design featuring a base unit with a guide and clamp system that exerts a squeezing force to secure the lifting column's housing, allowing for easy assembly and tool-free mounting, using a locking element that cooperates with the base unit and clamp to fix the housing in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lifting columns with box-shaped housing are secured using traditional longitudinal and cross members with multiple screws, then the mounting is stable, but the assembly process becomes time-consuming and cumbersome
Solution Approach 1:
The patent combines the longitudinal member and cross member into a single integrated base unit that directly receives the box-shaped housing. This merging eliminates the need for separate longitudinal and cross members, reducing the number of components and simplifying the assembly process while maintaining mounting stability through the integrated structure.
Solution Approach 2:
The base unit is designed with a specific compartment structure that segments the mounting function into distinct reception areas for the box-shaped housing. The compartment provides dedicated positioning features that guide and secure the housing, making assembly straightforward without requiring complex multi-component fastening systems.
2Reliability
If multiple longitudinal and cross members are used to secure lifting columns, then the structure is stable, but the device complexity increases
Solution Approach 1:
The patent merges multiple mounting components (longitudinal members and cross members) into a single integrated base unit. This base unit contains all necessary structural elements within one component, reducing the total number of parts while maintaining the structural stability that previously required separate members.
Solution Approach 2:
The base unit is designed as a universal mounting structure that performs multiple functions: it provides structural support, positions the box-shaped housing, and secures the lifting column. This multi-functional design eliminates the need for specialized longitudinal and cross members, simplifying the overall device complexity.
3Ease of operation
If a specialized mounting bracket design is used for lifting columns, then the assembly is simplified, but the adaptability to different furniture types is reduced
Solution Approach 1:
The base unit is designed with a universal compartment structure that can accommodate box-shaped housings of various dimensions and configurations. The compartment provides adjustable positioning features and standardized reception areas that work with different furniture types while maintaining simple assembly procedures.
Solution Approach 2:
The base unit incorporates adjustable parameters such as movable positioning elements and flexible compartment dimensions that can be adapted to different box-shaped housing sizes. This allows the same base unit design to work across various furniture types without sacrificing assembly simplicity.

AI summary
The invention relates to a supporting frame with a lifting column (59) comprising telescopically arranged profiles with an upper and lower end, said upper end having a housing (60) secured thereto, and a base unit (61,62,63) with a compartment at least for partial reception of the lifting column housing (60) and a locking element (75), which when placed in a locked position exerts a squeezing force between the base unit (61,62) and the housing (60) of the lifting column (59). Thus, the housing (60) of the lifting column (59) is positioned and fixed in the base unit (61,62,63). The supporting frame further comprises means for retaining the locking element (78) in the locked position.
