Solution Overview

Problem

Existing folding tables for aircraft lack intuitive and ergonomic movement sequences, result in increased design complexity and potential stability losses due to separate movement of the table top from the folding mechanism.

Innovation Solution

A guide device with a straight first guide track and a second guide track featuring a straight section and an arcuate section, allowing the support device to be guided linearly and pivoted through a 90° angle, enabling forced guidance of the table top from a vertical to a horizontal position with a single drive unit, enhancing stability and ergonomic operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the table top is guided separately from the folding mechanism, then the movement sequence can be controlled independently, but the design complexity increases and stability is reduced

Engineering Contradiction:
Improvemovement sequence controlVSAvoidnumber of joints
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the table top guidance function with the folding mechanism by integrating guide tracks into the existing support structure. The guide tracks are formed as integral parts of the support arms or housing, eliminating separate guidance components while maintaining controlled movement sequences during folding and extension operations.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If separate movement sequences are provided for table top and folding mechanism, then independent control is achieved, but the design effort increases

Engineering Contradiction:
Improveindependent controlVSAvoiddesign effort
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The design merges table top guidance with the folding mechanism into a unified structure. The guide tracks are incorporated into the support arms and housing as integral features rather than separate components, reducing design effort while maintaining the ability to control movement sequences through the unified mechanism's geometric constraints.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If multiple joints are used for separate guidance, then independent movement control is possible, but losses in stability occur

Engineering Contradiction:
Improveindependent movement controlVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent merges the guidance function into the rigid support structure itself, using the inherent stiffness of the support arms and housing to provide stable guidance. The guide tracks are formed as integral parts of these rigid structures, eliminating additional joints that would compromise structural stability while maintaining controlled movement through geometric constraints.

Inventive Principle:
Principle #5Merging (Combining)
