Solution Overview

Problem

Existing extendable tables with additional tabletops require manual and complex mechanisms for enlargement, which are expensive, prone to jamming, and have a high risk of functional failure.

Innovation Solution

An extendable table design featuring spring elements that automatically insert and pivot a center panel between two tabletops when extended, allowing for effortless enlargement without manual intervention, using guide elements and dampening mechanisms to ensure smooth operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual mechanisms are used to insert the center panel, then the table can be extended, but the mechanism becomes complex and expensive

Engineering Contradiction:
Improvetable extension capabilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The center panel is designed to insert itself automatically between the tabletops when they are pulled apart. The panel utilizes the movement of the tabletops to trigger its own insertion through guide elements and spring forces, eliminating the need for complex manual insertion mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The center panel is pre-positioned below the tabletops in a ready state. When the tabletops are pulled apart, the panel is already in position to be automatically inserted, eliminating the need for manual positioning or complex folding mechanisms during extension.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If manual handling of the center panel is required, then the table can be extended, but jamming and disruptions occur

Engineering Contradiction:
Improvetable extension capabilityVSAvoidunfolding reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The center panel automatically inserts itself between the tabletops using the movement of the tabletops to trigger the insertion. Guide elements ensure proper alignment and spring forces provide the necessary insertion force, eliminating manual handling that causes jamming and disruptions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Guide elements and spring forces act as intermediaries between the moving tabletops and the center panel. These intermediaries ensure smooth, controlled insertion of the panel without direct manual intervention, preventing jamming and ensuring reliable operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If complex folding mechanisms with springs are used, then the table can be extended, but the mechanism becomes prone to failure

Engineering Contradiction:
Improvetable extension capabilityVSAvoidfolding mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The center panel uses simple spring forces and guide elements to automatically insert itself when the tabletops are pulled apart. This self-service mechanism replaces complex folding mechanisms with a simple, reliable system that uses the natural movement of the tabletops to trigger panel insertion.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The center panel is pre-positioned below the tabletops and spring forces are pre-loaded in a ready state. When the tabletops are pulled apart, the pre-positioned panel and pre-loaded springs automatically execute the insertion, eliminating the need for complex folding mechanisms during operation.

Inventive Principle:
Principle #10Preliminary action

AI summary

Extendable table with two extendable table tops (1,2) and with a center panel (3), the center panel (3) being insertable between the table tops (1,2) when the table tops (1,2) are in the extended state. When the table tops (1, 2) are not in the extended state, the central panel (3) is arranged below the adjacent table tops (1, 2). When the table tops (1,2) are pulled out or after the table top (1,2) has been pulled out, the center plate (3) can be introduced automatically or automatically under the action of spring forces into the space between the table tops (1,2).
