Solution Overview

Problem

Existing folding tables are not suitable for office use due to lack of adjustable height and limited versatility, particularly requiring intermediate stops for height adjustment.

Innovation Solution

A folding table design with first and second height adjustment means that connect via female-male shaped and rotatable axle extensions, allowing continuous height adjustment without intermediate stops, and enabling easy transition between folded and unfolded positions without interfering with table legs or accessories.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the table legs are made movable between folded and unfolded positions for portability, then the folding table becomes suitable for storage and transport, but the height adjustment mechanisms become exposed and may interfere with the folding operation

Engineering Contradiction:
ImproveportabilityVSAvoidfolding operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The height adjustment mechanisms are extracted from the table legs and relocated to the tabletop. This separation allows the table legs to fold independently without interference from the height adjustment mechanisms, while the mechanisms remain accessible on the tabletop for operation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces intermediate connection elements (brackets, arms, linkages) that mediate between the tabletop height adjustment mechanisms and the table leg positioning. These intermediaries transmit motion and force while allowing independent operation of height adjustment and folding functions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional height adjustment mechanisms are used, then intermediate stops are provided for height positioning, but continuous height adjustment without intermediate stops is required for office use

Engineering Contradiction:
Improveheight adjustment rangeVSAvoidheight adjustment mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical intermediate stop mechanisms with a continuous adjustment system using threaded rods, nuts, and locking mechanisms. This substitution allows smooth continuous height adjustment without discrete intermediate stops, providing infinite positioning possibilities within the adjustment range.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the table legs extend perpendicular from the tabletop in unfolded position, then sufficient legroom is provided comparable to regular office desks, but the height adjustment mechanisms may interfere with the folding operation

Engineering Contradiction:
ImprovelegroomVSAvoidmechanism coordination
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the height adjustment function from the leg folding function by placing adjustment mechanisms on the tabletop rather than integrated into the legs. This segmentation allows the legs to extend perpendicular for optimal legroom while the separate tabletop-mounted mechanisms avoid interference during folding operations.

Inventive Principle:
Principle #1Segmentation

AI summary

Folding table (1) comprising a tabletop (2) and table legs (3, 4) which are movable between a folded down position and an unfolded position in which the table is ready to use and wherein the tabletop (2) has an adjustable height position. In the unfolded position the table legs extend essentially perpendicular from the tabletop. The tabletop is provided with first height adjustment means (5) which are motor or hands driven, and the table legs are provided with second height adjustment means. The first height adjustment means that are provided on the tabletop are releasably connectable with the second height adjustment means that are provided in the table legs.
