Solution Overview
Problem
Conventional building devices require a larger frame than the house to be built, leading to inefficiencies and space constraints, especially for large houses, due to the shortage of labor in the construction field.
Innovation Solution
A 3D printing building device with a rotatable crossbeam and a discharging mechanism that can move along the crossbeam, allowing for the release of building materials within a smaller area, enabling the construction of houses with a smaller footprint and greater convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional building device uses a frame structure with larger volume and floor area, then the house can be built within the frame, but the device occupies excessive space and is inconvenient for building, especially large houses
Solution Approach 1:
The crossbeam is designed to be rotatable around the central axis of the stand column, transforming from a static structure to a dynamic one. This rotation capability allows the discharging mechanism to reach different positions and release building materials to various locations within the building area, enabling the construction of large houses without requiring a excessively large device footprint. The rotatable crossbeam provides operational flexibility and adaptability.
Solution Approach 2:
The discharging mechanism is made movable along the crossbeam, adding a translational degree of freedom to the system. Combined with the rotational capability of the crossbeam, this creates a two-dimensional movement space that allows the discharging mechanism to cover a large building area from a relatively small device footprint. The mechanism can move radially along the crossbeam while the crossbeam rotates, effectively utilizing spatial dimensions to expand coverage without increasing the device's base area.
2Adaptability or versatility
If the frame of the building device is made larger to accommodate the house, then the house structure can be supported, but the device becomes more complex and occupies more space
Solution Approach 1:
The rotatable crossbeam serves multiple functions: it acts as a structural support element, a positioning mechanism for the discharging mechanism, and a motion transmission component. The discharging mechanism itself is multi-functional, being both movable along the crossbeam and capable of rotating to discharge materials in different directions. This multi-functionality reduces the need for separate components, thereby reducing overall structural complexity while maintaining adaptability for building various house structures.
Solution Approach 2:
By making the crossbeam rotatable and the discharging mechanism movable, the system achieves adaptability through dynamic reconfiguration rather than through a larger static frame. The mechanism can adjust its position and orientation as needed for different building tasks, providing versatility without requiring a permanently large and complex structural framework.
3Productivity
If a larger frame is used to build large houses, then the house can be constructed, but the device requires more space and labor, which is problematic given labor shortages
Solution Approach 1:
The building device is designed to be self-positioning and self-adjusting through its rotatable crossbeam and movable discharging mechanism. The system can autonomously reconfigure its working position and orientation without requiring manual intervention or labor-intensive adjustments. This self-service capability significantly reduces the labor required for operation while maintaining high construction efficiency, addressing both productivity and ease of operation concerns.
Solution Approach 2:
The dynamic components (rotatable crossbeam, movable discharging mechanism) enable the device to adapt its configuration automatically to different building requirements. This reduces the need for manual reconfiguration and labor-intensive operations, thereby improving ease of operation. Simultaneously, the efficient use of space and materials by the compact, dynamically adjustable device enhances construction productivity in the context of labor shortages.

AI summary
Disclosed are a building device and a house built by using the building device. The building device includes: a stand column extending in a longitudinal direction; a crossbeam extending in a transverse direction, the crossbeam being connected with the stand column and rotatable around a central axis of the stand column; and a discharging mechanism being connected with the crossbeam and movable along the crossbeam, a discharging port of the discharging mechanism facing a building area. With this building device, it is more convenient to build a house.
