Solution Overview

Problem

Existing construction boxes for rapid prototyping installations are cumbersome and require separate devices for moving and lifting, leading to inefficiencies in the construction and unpacking processes, as well as increased installation height and complexity.

Innovation Solution

Integration of a construction box travel drive and platform lift drive within the construction box, allowing for automated and controlled movement between construction and unpacking positions, reducing the need for external devices and minimizing installation height.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate devices are used for moving and lifting the construction box, then the construction box can be moved and positioned, but the device complexity and installation height increase

Engineering Contradiction:
Improveconstruction box movement and positioningVSAvoidseparate moving and lifting devices
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the travel drive and platform lift drive into a single integrated drive unit mounted on the construction box. This merging of previously separate moving and lifting devices into one compact unit reduces overall device complexity while maintaining all necessary functions for construction box movement and positioning.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated drive unit serves multiple functions: it provides both the travel drive for moving the construction box horizontally and the platform lift drive for vertical positioning. This multi-functionality eliminates the need for separate dedicated devices, reducing complexity while improving operational efficiency.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Ease of operation

If separate devices are used for moving and lifting the construction box, then the construction box can be moved and positioned, but the installation height increases

Engineering Contradiction:
Improveconstruction box movement and positioningVSAvoidinstallation height
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

By merging the travel drive and platform lift drive into a single integrated unit mounted on the construction box, the overall installation height is reduced. The combined drive unit occupies less vertical space compared to having separate lifting and moving devices, thereby reducing the required installation height while maintaining full functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If automated travel drive and lift drive are integrated into the construction box, then the construction and unpacking processes are streamlined, but the construction box complexity increases

Engineering Contradiction:
Improveconstruction and unpacking process efficiencyVSAvoidintegrated drive system in construction box
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The construction box is equipped with self-contained automated travel and lift drives that enable it to move and position itself without external intervention. This self-service capability streamlines construction and unpacking processes by allowing the construction box to autonomously navigate to required positions, improving productivity despite the increased internal complexity of the integrated drive system.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a construction box (200) comprising a front wall (220), a rear wall and two side walls (224, 226), which delimit a construction box interior that houses a height-adjustable construction platform (210). The construction box (200) has dedicated travelling gear (250) integrated in to the construction box for propelling said box (2000 between a construction position, in which the construction box (2000 is positioned within the frame (150) of the system (100) to allow the shaped body to be built up and an additional construction box position, such as a construction box unpacking position, in which the construction box (200) is propelled out of the frame (150) of the system (100) to permit the unpacking of the built-up shaped body.
