Engineering Contradiction Analysis
1Productivity
If traditional construction methods are used, then multiple skill sets and sequential processes can be utilized, but the construction period extends to several months
Solution Approach 1:
The patent combines multiple construction operations (depositing material, forming walls, creating windows, installing reinforcement) into a single automated 3D printing process. The printing assembly integrates material deposition, layer formation, and structural creation in one continuous operation, eliminating the need for sequential manual trades and significantly reducing construction time from months to days or weeks.
Solution Approach 2:
The invention changes the construction process from manual, discrete operations to automated, continuous additive manufacturing. By using extrudable building materials deposited in vertically stacked layers under automated control, the system transforms the construction parameters from labor-intensive sequential tasks to machine-driven continuous deposition, achieving rapid construction while maintaining quality.
2Ease of manufacture
If traditional construction methods are used, then structures can be built with conventional materials, but the process is time-consuming and complex
Solution Approach 1:
The patent extracts the essential construction function from multiple manual trades and consolidates it into a single 3D printing system. By taking out the core function of material deposition and structural formation and automating it through additive manufacturing, the process simplifies construction while accelerating it, reducing the need for multiple skill sets and sequential coordination.
Solution Approach 2:
The 3D printing system performs construction operations autonomously without requiring multiple human trades. The automated printing assembly deposits material, forms structures, and creates architectural features through programmed motion along orthogonal axes, making the construction process self-sufficient and eliminating the complexity of coordinating multiple manual operations.
3Loss of time
If additive manufacturing is used, then construction time is significantly reduced, but the system requires complex gantry and rail assembly mechanisms
Solution Approach 1:
The gantry system is designed as a multi-functional platform that performs multiple construction tasks through a single automated assembly. The printing assembly on the gantry can deposit material, form various wall configurations, create window openings, and integrate reinforcement, all through programmed motion. This universal system replaces multiple specialized construction tools and processes, justifying its complexity by consolidating numerous functions into one device.
