Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame structures for large tables lack variability in geometry and dimension, rigidity under high loads, and practical assembly methods, making them inefficient for series production or individual shapes at affordable costs.
Innovation Solution
A frame structure with a base featuring connection means for multiple carriers and consoles, allowing flexible orientation and attachment to the tabletop, comprising a central core with circular holes and grooves for screw fixation, enabling horizontal rotation and adjustable support for enhanced stability and assembly convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame structure uses fixed connection points for feet and supports, then the assembly is simple, but the geometry and dimensions of the tabletop are limited in variability
Solution Approach 1:
The base is divided into two parallel plates with multiple holes arranged in circles, allowing selective connection points. This segmentation enables various geometries and dimensions by choosing different hole combinations, while keeping the base structure itself simple and standardized for efficient production.
Solution Approach 2:
The base with its multiple connection holes serves multiple functions: it can connect to carriers in different directions, attach consoles at various positions, and support different tabletop geometries. This multi-functionality achieves geometry variability without proportionally increasing structural complexity.
2Area of stationary object
If the tabletop is made up of several segments for large dimensions, then the table can accommodate large work surfaces, but the rigidity to prevent bending under high loads becomes insufficient
Solution Approach 1:
The base structure adds a vertical dimension with two parallel plates spaced apart, creating a three-dimensional rigid framework. This vertical spacing between plates, combined with the circular hole patterns, provides structural rigidity that prevents bending of large segmented tabletops while maintaining the ability to accommodate large areas.
3Adaptability or versatility
If the connection means on the base are used only for connecting to carriers, then the structure is simple, but the ability to connect to consoles and attach to tabletop underside is limited
Solution Approach 1:
The base is pre-configured with multiple holes arranged in circular patterns on two parallel plates during manufacturing. This preliminary arrangement of connection points allows for versatile connections to carriers, consoles, and tabletops during assembly without requiring complex on-site modifications, thus maintaining production efficiency while achieving connection versatility.
4Productivity
If the frame structure is designed for specific tabletop configurations, then the manufacturing is efficient, but the range of table top configurations is narrow
Solution Approach 1:
The base design uses variable parameters such as the number of holes, their radial positions, and angular arrangements in circular patterns. By changing these parameters, the same base structure can accommodate different tabletop configurations for series production while maintaining manufacturing efficiency. The standardized base with adjustable connection patterns resolves the contradiction between production efficiency and configuration variety.

AI summary
Disclosed is a frame structure for a table. Said frame structure comprises a tabletop (1) which is supported by legs (2) and is provided with a top surface (11) as a working surface and a bottom surface (12), a support (4) mounted on the bottom surface (12) of the tabletop (1), and a base (3) for each leg (2). Said base (3) is located underneath the tabletop (1) and has a receiving zone (A) in which the associated leg (2) is mounted. The base (3) is equipped with connecting means (30, 32; 37, 38) which are to be connected to several supports (4) that extend in different optional directions. In addition to being connected to at least one support (4), the connecting means (30, 32; 37, 38) can be connected to at least one bracket (5) that extends in a different direction than the support (4). The bracket (5) can be fastened to the bottom surface (12) of the tabletop (1). Unused connecting means (30, 32; 37, 38) on the base (3) can be fastened to the bottom surface (12) of the tabletop (1). The connecting means encompass a first disk (30) and a second disk (37) that is arranged at a distance from and parallel to the first disk (30). The first disk (30) and the second disk (37) are interconnected by means of a central core (36) such that the base (3) has a wheel rim-type shape. Congruent holes (32, 38), which are used for connecting the supports (4) and brackets (5), are systematically arranged in a circle within the first and second disk (30, 37), outside the core (36). The receiving zone (A) that is to be connected to a leg (2) is formed by a central depression in the second disk (37). Said depression is open towards the outside while being in contact with the core (36) towards the inside. The upper end (211) of the brace piece (21) of each leg (2) is provided with a segment (22) which is fixedly disposed on said brace piece (21) and can be positively inserted into the receiving zone (A).
