Movable Table Angular Leg Assembly for Inline Fastening Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard table assemblies with angular connections are prone to failure due to insecure connections between the base, leg, and surface, leading to higher manufacturing and shipping costs, and existing fixed assemblies do not provide a robust and cost-effective solution.
Innovation Solution
A table assembly with a single angular leg or stem secured to the base and surface using fasteners, featuring integrated connecting nubs and apertures that align for inline fastening, preventing counter-directional forces and ensuring a robust connection without unnecessary torque.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If angular connections are used between base, leg, and surface, then flexibility and comfort are improved, but connection reliability deteriorates due to insecure fastening
Solution Approach 1:
The patent introduces an intermediary component (the angular connection mechanism with cavity and nub) that mediates between the base/leg/surface components. This intermediary structure provides a dedicated interface for angular fastening, allowing flexibility in configuration while ensuring reliable connection through the cavity-nub interface that prevents counter-directional forces.
Solution Approach 2:
The patent changes the connection parameter from standard 90-degree angles to variable angular connections. The connecting nubs are positioned at specific angles relative to the base and surface, allowing the connection to accommodate different angular configurations while maintaining structural integrity through the engineered cavity-nub interface.
2Ease of manufacture
If fixed assembly without fasteners is used, then manufacturing and shipping costs are reduced, but connection strength deteriorates
Solution Approach 1:
The patent extracts the fastening function from a separate component and integrates it into the structure itself through the cavity-nub interface. The connecting nubs are formed as integral parts of the base and surface, with cavities provided to receive fasteners, thereby providing robust mechanical connection while maintaining manufacturing efficiency.
Solution Approach 2:
The patent merges the structural components (base, leg, surface) with the fastening interface (cavities and nubs) into a unified assembly. The connecting nubs are integrated directly within the construction of the base and surface, combining structural support and connection functions in a single robust assembly.
3Ease of manufacture
If standard 90-degree connections are used, then manufacturing simplicity is improved, but adaptability deteriorates due to limited positioning options
Solution Approach 1:
The patent employs asymmetric angular connections where the connecting nubs are positioned at specific non-standard angles relative to the base and surface. This asymmetric configuration provides multiple positioning options and flexibility in arrangement while maintaining manufacturing simplicity through the standardized cavity-nub interface design.

AI summary
A movable table assembly comprising a base portion and a table support each having angular connecting nub with an interior cavity to enable fastening inline with a support leg. The preferred assembly utilizes a base portion, a support leg, a table support, and a table. The base portion and table support being generally planar and having a first side and second side defined by an edge around a perimeter. The support leg coupled between the base portion and table support to generally provide a movable work surface, wherein the table and base portion are generally positioned parallel to a ground surface despite the angular connection.
