Solution Overview

Problem

Existing coupling devices for modular construction require significant space due to the use of spacers, leading to wide spacing between components, which is undesirable for structural integrity and efficient use of space, and often necessitate time-consuming welded connections.

Innovation Solution

A coupling device with a base body designed as a corner or edge element that eliminates the need for additional spacers, allowing components to be closely arranged, using screw connections and positioning elements for secure and efficient assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a spacer is used as the base body for coupling components, then the coupling device can provide a standardized connection structure, but the distance between coupled components becomes large, reducing structural integrity and wasting space

Engineering Contradiction:
Improvestandardized connection structureVSAvoiddistance between components
Core Design Contradiction:
Ease of manufactureVSLength of stationary object

Solution Approach 1:

The invention extracts and eliminates the spacer component from the coupling system. Instead of using a separate spacer base body that creates distance, the coupling device integrates directly into the component wall structure, removing the unnecessary intermediate element that was causing the space problem

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The coupling device is merged with the component wall structure itself. The base body is designed to be integrated into the wall of the first component, combining what were previously separate elements (component and spacer) into a unified structure that eliminates the gap

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If spacers are used in coupling devices, then components can be easily connected, but valuable space in warehouses and transport vehicles is wasted

Engineering Contradiction:
Improveease of connectionVSAvoidspace utilization
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The spacer element is extracted and removed from the system. The coupling device uses the component's own wall structure as the mounting base, eliminating the need for additional spacer volume that would otherwise be required for the coupling mechanism

Inventive Principle:
Principle #2Taking out (Extraction)

3Strength

If welded connections are used to join structural elements, then strong connections are achieved, but the process becomes time-consuming and complex

Engineering Contradiction:
Improveconnection strengthVSAvoidassembly speed
Core Design Contradiction:
StrengthVSProductivity

Solution Approach 1:

The invention replaces the welding process (thermal/chemical joining) with a mechanical coupling system. The coupling device uses threaded rods and engagement elements that provide strong mechanical connections without requiring welding operations, thereby increasing assembly speed and reducing complexity

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

Solution Approach 2:

The connection system is segmented into separate functional elements: the coupling device integrated in the wall, the threaded rod, and the engagement element. This segmentation allows for pre-fabrication and rapid assembly, replacing the monolithic welding process with modular mechanical components that can be quickly assembled

Inventive Principle:
Principle #1Segmentation
