Solution Overview

Problem

Additive manufacturing processes face downtime due to the need to keep the loading path free for removing used modules, preventing fresh modules from being brought to the work position until the used ones are fully removed.

Innovation Solution

The plant allows modules to be moved from the tunnel structure into a work position along a loading direction and out of the apparatus along an unloading direction, where the loading and unloading directions differ from the tunnel transport direction, enabling continuous operation without waiting for used modules to be completely removed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the loading path is kept free for removing used modules, then the used modules can be removed completely, but fresh modules cannot be brought to the work position until the used modules are removed, leading to downtime

Engineering Contradiction:
Improvemodule removalVSAvoidapparatus downtime
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent divides the module transport path into two separate paths: a loading path for bringing fresh modules to the work position, and an unloading path for removing used modules from the work position. This segmentation allows both operations to occur simultaneously without interfering with each other, eliminating the downtime that occurred when a single shared path was used.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension by creating separate loading and unloading paths that diverge from the tunnel transport direction. The loading path extends in a first direction while the unloading path extends in a second direction, allowing modules to be loaded and unloaded simultaneously without blocking each other's movement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If a single path is used for both loading and unloading modules, then the structure is simple, but the apparatus experiences downtime when module replacement is needed

Engineering Contradiction:
Improvetransport path structureVSAvoidadditive manufacturing efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The transport system is segmented into distinct loading and unloading paths, allowing simultaneous module replacement operations. The loading path and unloading path are separated both in space and in function, enabling continuous operation without the productivity loss that would result from using a single shared path.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If the loading and unloading directions are the same as the tunnel transport direction, then the module movement is straightforward, but fresh modules cannot be brought to the work position before used modules are fully removed

Engineering Contradiction:
Improvemodule transportVSAvoidapparatus downtime
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent changes the direction of module transport by introducing loading and unloading paths that extend in directions different from the tunnel transport direction. The loading path extends in a first direction while the unloading path extends in a second direction, allowing modules to be moved in and out of the work position simultaneously without blocking each other, thus eliminating downtime.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
