Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional building construction techniques are inflexible and inefficient, requiring significant material and time to adapt to changing structural requirements, as they can only factor in known requirements during the initial planning phase, leading to waste and inefficiency when unforeseen changes occur.
Innovation Solution
A method for generating a mesh structure that involves processing a mesh geometry based on input parameters to define an operational environment and generating robot instructions for adding or removing material to modify the structure, allowing for location-dependent and variable fabrication settings, enabling the creation of optimized structures that can adapt to changing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional techniques use global feed wire application with defined spacing and wire length, then the fabrication process is simple, but the amount of material used increases significantly to fulfill all structural requirements
Solution Approach 1:
The patent applies local quality by enabling variable feed wire spacing, orientation, and length at different locations on the mesh structure. The system determines local structural requirements and applies material only where needed, creating regions with different densities and properties to optimize both material usage and structural performance
Solution Approach 2:
The system dynamically adjusts fabrication parameters during the manufacturing process. Instead of using fixed global settings, the robot controller modifies feed wire spacing, orientation, and length in real-time based on the specific structural requirements of each location being fabricated
2Reliability
If conventional techniques fabricate a three-dimensional structure based on initial planning phase requirements, then the structure meets initial requirements, but it cannot adapt to changing requirements without wasting time and material
Solution Approach 1:
The system performs preliminary structural analysis and determines feed wire placement requirements before fabrication begins. By calculating and planning the optimal feed wire configuration in advance based on structural requirements, the system ensures the structure will meet its design goals while minimizing material usage
Solution Approach 2:
The system incorporates feedback mechanisms where structural requirements and environmental settings are continuously evaluated. If requirements change, the system can recalculate and adjust the feed wire application parameters to meet new requirements, enabling adaptation without complete reconstruction
3Ease of manufacture
If conventional techniques apply feed wire globally with uniform spacing, then the fabrication process is straightforward, but it is difficult to fulfill various location-dependent structural requirements
Solution Approach 1:
The system implements local quality by determining specific feed wire spacing, orientation, and length requirements for each location on the mesh structure based on local structural analysis. This allows different regions to have optimized properties tailored to their specific structural needs
Solution Approach 2:
The system changes multiple fabrication parameters simultaneously including feed wire spacing, orientation, and length based on location-specific requirements. The robot controller adjusts these parameters dynamically to achieve precise control over the final structure's properties at each location
