Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional erecting formwork and cast-in-place concrete are used for ramp protection, then construction can be performed on non-horizontal planes, but construction progress is slow, resource demands are high, and safety is lower
Solution Approach 1:
The printing device is designed with movable and adjustable components including extendable legs with adjustable lengths, rotatable print carriages, and multi-directional nozzles. These dynamic features enable the device to adapt to non-horizontal planes and complex terrains while maintaining efficient 3D printing construction progress
Solution Approach 2:
The 3D printing device integrates multiple functions including terrain adaptation through adjustable legs, multi-angle printing capability via rotatable carriages and nozzles, and automated concrete deposition. This multi-functional design replaces conventional formwork and casting methods, achieving both adaptability to various terrains and improved construction productivity
2Productivity
If 3D printing is performed on flat ground or prefabricated members, then construction efficiency is improved, but application capability in complex terrains and narrow regions is limited
Solution Approach 1:
The device employs dynamically adjustable legs that can extend and rotate to different lengths and angles, allowing the printing carriage to maintain stable printing positions on uneven ground. The rotatable print carriage and multi-directional nozzle further enable adaptation to complex terrains and narrow regions while preserving 3D printing efficiency
Solution Approach 2:
The printing device adds vertical and rotational dimensions to the conventional horizontal printing capability. Through extendable legs with adjustable heights and rotatable print carriages, the device can operate on non-horizontal planes and access complex terrains, expanding application capability beyond flat ground while maintaining construction efficiency
3Adaptability or versatility
If the bottom of a to-be-printed building is not horizontally disposed, then real-world construction scenarios are covered, but existing 3D printing devices cannot perform printing
Solution Approach 1:
The device incorporates dynamically adjustable legs with extendable and rotatable capabilities, allowing operators to easily adjust leg lengths and angles to match the underlying terrain. The rotatable print carriage and multi-directional nozzle further simplify operation on sloped surfaces, making the device easy to operate across diverse terrains
Solution Approach 2:
The printing device includes self-leveling and terrain-adaptation capabilities through automated adjustment mechanisms. The system can automatically adjust leg extensions and carriage rotations to compensate for non-horizontal surfaces, reducing the need for manual intervention and maintaining printing capability across various terrains
