Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional object forming technologies face difficulties in easily adjusting or changing the physical properties of formed objects, as they require changing the forming material to achieve desired properties, and adjusting internal structure density is not accurate enough to achieve desired physical properties.
Innovation Solution
A three-dimensional object data generation apparatus that uses a setting unit to arrange thresholds in a three-dimensional space based on a predetermined basic shape, and a calculation unit to determine voxel formation based on physical property values, allowing for precise adjustment of physical properties by controlling voxel formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If forming material is changed to achieve desired physical property, then physical property can be adjusted, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies local quality by assigning different physical property values to different voxels within the three-dimensional object. Each voxel can have independently adjusted physical properties through the threshold matrix, allowing localized modification of strength and other properties without changing the entire forming material. This enables precise control of physical properties at specific locations while maintaining manufacturing simplicity.
Solution Approach 2:
The patent changes physical parameters by modifying the threshold values in the three-dimensional threshold matrix rather than changing materials. By adjusting threshold parameters, the system controls which voxels are formed and what physical properties they exhibit, enabling flexible adjustment of physical properties through parameter modification instead of material substitution.
2Strength
If density of internal structure is adjusted to achieve desired physical property, then physical property can be modified, but manufacturing precision is insufficient to accurately achieve desired properties
Solution Approach 1:
The patent segments the three-dimensional object into discrete voxels, each of which can be independently controlled through the threshold matrix. This segmentation allows precise control over the formation of each voxel based on its physical property requirements, enabling accurate achievement of desired physical properties through selective voxel formation rather than relying on overall density adjustment.
Solution Approach 2:
The patent uses parameter changes by adjusting threshold values in the three-dimensional threshold matrix to precisely control voxel formation. Each threshold value determines whether a corresponding voxel is formed, allowing precise control of physical properties at the voxel level. This parameter-based control mechanism achieves manufacturing precision that cannot be obtained through coarse density adjustment alone.
3Strength
If conventional methods are used to adjust physical properties, then material composition can be controlled, but adaptability and flexibility are reduced
Solution Approach 1:
The patent applies universality by using a single three-dimensional threshold matrix system to control multiple physical properties simultaneously. The same threshold matrix mechanism can adjust strength, density, porosity, and other physical properties by modifying threshold values, providing multi-functional control without requiring separate systems for each property adjustment, thereby enhancing adaptability and flexibility.
Solution Approach 2:
The patent introduces dynamics by making the threshold matrix adjustable and reconfigurable. The threshold values can be dynamically modified to adapt to different physical property requirements, allowing the system to respond flexibly to changing design requirements. This dynamic adjustment capability enables versatile control of physical properties without fixed material constraints.
