Angle-Shaped Bar with Segmented Connection for Modular Table Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture configurations, such as tables and desks, require bars of specific lengths, which are costly and time-consuming to produce, and traditional methods of connecting bars are not efficient for reconfiguration or transportation.
Innovation Solution
An angle-shaped bar with a longitudinal extension and ridges that allows for easy connection of multiple bars to form longer bars, using scored holes for fastening, which increases stability and reduces production costs by allowing for bars of varying lengths to be created from a single type of bar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bars are welded directly to each other to form longer bars, then the connection strength is improved, but the ease of transportation and reconfiguration deteriorates
Solution Approach 1:
The bar is divided into multiple separate segments that can be connected through holes and fastening means rather than being welded together. This allows the bar to be disassembled for transportation and reconfigured for different lengths while maintaining connection strength through the fastening system.
Solution Approach 2:
Fastening means (screws, nuts, or screw nuts) are introduced as intermediary elements to connect bar segments. These intermediaries provide strong connections without requiring welding, enabling both strong assembly and easy disassembly for transportation and reconfiguration.
2Stability of the object's composition
If bars are made at specific lengths to match tables or desks, then the stability of the furniture construction is improved, but the productivity and adaptability deteriorate
Solution Approach 1:
A single type of bar segment with standardized holes can be used to create bars of multiple different lengths by connecting different numbers of segments. This universal design eliminates the need to produce separate bar types for different lengths, reducing production costs and time while maintaining stable furniture constructions.
Solution Approach 2:
The bar system transitions from fixed, pre-determined lengths to a dynamic configuration system where lengths can be adjusted by connecting or disconnecting segments. This allows the same bar segments to adapt to different furniture requirements, improving productivity and reducing the need for multiple specialized bar types.
3Manufacturing precision
If multiple tools are used to produce bars of different lengths, then the manufacturing precision is improved, but the device complexity and cost increase
Solution Approach 1:
By segmenting the bar into standardized modules with pre-drilled holes at regular intervals, the need for multiple custom-length tools is eliminated. A single set of tools can produce all bar segments, and the desired length is achieved by connecting the appropriate number of segments, maintaining precision without increasing tool complexity.
Solution Approach 2:
Instead of changing the physical parameters of the bars (lengths) to match different furniture pieces, the invention changes the configuration parameter by connecting or disconnecting standardized segments. This approach maintains manufacturing precision with a single tool set while achieving variable effective lengths through assembly rather than custom fabrication.

AI summary
A bar for supporting a table, includes an angle shaped bar having a longitudinal extension, including a first side and a second side extending perpendicular relative each other, at least one first hole through the first side of the angle shaped bar, adapted for connecting two bars together longitudinally so as to form a longer bar, a ridge, extending along the longitudinal edge of the first side of the angle shaped bar, wherein the ridge is adapted to longitudinally limit movement of connected bars.
