Engineering Contradiction Analysis
1Productivity
If planar stacking method is used for 3D printing architecture, then construction efficiency is improved, but the strength and toughness of the printed architecture deteriorates due to lack of reinforcing ribs
Solution Approach 1:
The patent combines filaments (reinforcing ribs) with concrete to form a composite structure. The filaments are embedded within the concrete layers, creating a reinforced concrete architecture that maintains the efficiency of additive construction while significantly improving strength and toughness through the composite material system.
Solution Approach 2:
The architecture is constructed in discrete layers with filaments segmented and arranged in specific patterns within each layer. This segmentation allows for systematic reinforcement throughout the structure, with filaments positioned to provide structural support while maintaining the layer-by-layer construction efficiency.
2Reliability
If materials are transported from distant places for construction, then construction quality can be ensured, but transportation costs increase
Solution Approach 1:
The system utilizes locally available materials and environmental resources for construction. By adapting to the local environment and using on-site materials where possible, the construction process reduces dependence on distant material transport while maintaining structural quality through intelligent design and local resource utilization.
3Ease of manufacture
If traditional 3D printing method is used, then construction process is simple, but weak interlayer bonding interfaces are created reducing structure durability
Solution Approach 1:
The filaments are pre-positioned within the concrete layers before final curing. This preliminary placement of reinforcing elements ensures that the bonding interfaces between layers are strengthened in advance, preventing weak points from forming during the construction process while maintaining the simplicity of the additive manufacturing approach.

AI summary
A bionic architecture construction method includes: obtaining architecture parameters; analyzing the architecture parameters to obtain filament segment parameters, pillar parameters, and concrete parameters; controlling, based on the pillar parameters, a robotic arm to perform drilling, and inserting a telescopic rod and controlling extension and contraction of the telescopic rod to form a pillar; controlling, based on the filament segment parameters, the robotic arm to extrude filaments between the pillar and a preset ground surface so as to form filament segments, where the filament segments are cooperatively arranged to form a cocoon-like skeleton; pouring concrete into the cocoon-like skeleton based on the concrete parameters to form a cocoon-like shell, where the cocoon-like shell is a closed structure with the filament segments embedded within the concrete; and controlling, based on the architecture parameters, the robotic arm to form a window and a door on the cocoon-like shell to form an architectural shell.
