Solution Overview

Problem

Existing modular support structures, such as deployable bridges, face challenges with stability and ease of assembly due to the need for numerous loose connecting elements and potential unwanted movement of components in tongue and groove connections.

Innovation Solution

A modular support structure design where components are connected via a carrier with a T-shaped connecting element and side stops, eliminating the need for loose connecting elements and preventing lateral movement by integrating the connecting element and side stops into the carrier.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional tongue and groove connections are used to connect plate-shaped components, then the components can be connected together, but a large number of loose connecting elements are required

Engineering Contradiction:
Improveease of assemblyVSAvoidnumber of connecting elements
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The connecting element is integrated into the carrier as a fixed component rather than being a separate loose element. The carrier carries the components and includes the connecting element with a groove and tongue as integral parts, eliminating the need for multiple loose connecting elements while maintaining the tongue and groove connection functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Stability of the object's composition

If components are connected using loose connecting elements, then connection is possible, but unwanted displacements of components relative to one another occur in the direction of the groove

Engineering Contradiction:
Improvecomponent stabilityVSAvoidassembly simplicity
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The side stops are integrated into the carrier as fixed components rather than separate elements. This integration provides lateral guidance and prevents unwanted displacements of components in the groove direction while maintaining assembly simplicity through the unified carrier structure.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If transverse elements are made solid for stability, then the bridge structure is stable, but the elements become heavy and difficult to handle

Engineering Contradiction:
Improvebridge stabilityVSAvoidelement weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The bridge structure is divided into modular plate-shaped components that can be individually handled and transported. The carrier system with integrated connecting elements provides stability when assembled while allowing individual components to remain lightweight and manageable during transport and assembly.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If multiple loose connecting elements are used to connect components, then connections can be made, but assembly becomes more complex and time-consuming

Engineering Contradiction:
Improveconnection flexibilityVSAvoidassembly speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The carrier integrates multiple functions - it carries the components, provides the connecting element with groove and tongue for joining components, and includes side stops for lateral guidance. This integration reduces the number of separate elements to be handled during assembly, thereby increasing assembly speed while maintaining connection flexibility.

Inventive Principle:
Principle #5Merging (Combining)
