Folding Table with Hinged Lock for Adjustable Angle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding tables with existing structures cannot fix the table top at angles other than 0° or 90° relative to the table legs, limiting their usability and occupy more space during transportation due to fixed connections between the legs and the grounded part.
Innovation Solution
Incorporating a second hinged lock that allows the table leg and grounded part to be locked at any included angle between 0° to 90°, enabling adjustable positioning and facilitating convenient storage, transportation, and carrying by allowing the table leg and grounded part to rotate relative to each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table top and table leg are fixedly connected, then the structure is simple and stable, but the table top cannot be adjusted to different angles and occupies more space during transportation
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed connection between table top and table leg into a hinged connection that allows relative rotation. The hinged lock mechanism enables the table top to be adjusted to different angles (0° to 90°) while maintaining structural stability when locked, and allows folding to a compact state for transportation.
2Adaptability or versatility
If the table leg and grounded part are fixedly connected, then the structure is stable, but the folding table cannot be folded and occupies more space during transportation
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed connection between table leg and grounded part into a hinged connection. The second hinged lock mechanism enables the table leg to be folded relative to the grounded part, reducing the overall volume for transportation while maintaining stability when unfolded and locked for use.
3Adaptability or versatility
If the table top can rotate relative to the table leg, then the table top can be positioned at different angles, but the table top cannot be fixed within a 90° range of rotation
Solution Approach 1:
The patent applies the intermediary principle by introducing a hinged lock mechanism as a mediator between the table top and table leg. This lock acts as an intermediary element that can be engaged at different positions within the 0° to 90° rotation range, allowing the table top to be fixed at various angles while maintaining stable positioning when locked.

AI summary
A folding table comprises a table top, a table leg, a grounding part supported on the ground or a table top, and a second hinged lock formed for the table leg and the grounding part after the table leg and the grounding part rotate relative to each other, one end of the second hinged lock is connected with the other end of the table leg, the other end of the second hinged lock is connected with the grounding part, the table leg or the grounding part are relative to each other. When rotating in the unlocked state, the second hinged lock locks the table leg and the grounding part at an included angle of 0-90°. The invention has the advantages of convenient storage, transportation or carrying and small occupation space.
