Modular 3D Avatar Assembly Using Puzzle-Like Printed Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D printing technologies face challenges in producing large, customized objects, such as human-size avatars, due to the high cost, size, and complexity of available printers, as well as the need for additional support structures, which are costly and environmentally inefficient.
Innovation Solution
A method involving 3D scanning, scaling, cutting the model into puzzle-like pieces, and assembling these pieces using a lock-and-key mechanism, allowing for assembly and disassembly, with optional electronic integration, to create a customizable, porous structure that can be printed using common 3D printers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If big 3D printers are used to print human-size objects, then the object size can be achieved, but the device cost and complexity become too high for widespread use
Solution Approach 1:
The patent divides the large object into multiple smaller parts that can be printed by standard 3D printers. These parts are then assembled together to form the complete human-size object, eliminating the need for expensive big 3D printers while achieving the desired scale.
2Ease of manufacture
If traditional 3D printing is used for large objects, then objects can be produced, but extensive support structures are required causing material waste and increased cost
Solution Approach 1:
By dividing the object into multiple smaller printable parts, each part can be optimized to minimize or eliminate support structures during printing. This segmentation reduces overall material waste from supports while maintaining manufacturability of the complete assembly.
Solution Approach 2:
The patent employs dynamic support structures that are strategically placed only where needed during the printing process, rather than using extensive static support throughout. This reduces material waste while ensuring successful printing of complex geometries.
3Strength
If large objects are printed in one piece, then structural integrity is maintained, but storage and transport become difficult
Solution Approach 1:
The patent segments the large object into multiple smaller parts that are easier to store and transport. These parts are designed with connection features that ensure structural integrity when assembled, combining the benefits of modular handling with strong overall structure.
Solution Approach 2:
The patent designs the segmented parts to nest within each other when not in use, optimizing storage space. The smaller components can be stored inside larger components, making the entire system compact for transport and storage while maintaining structural integrity when assembled.
4Adaptability or versatility
If standard 3D printing is used for customized objects, then production flexibility is achieved, but cost becomes too high for small companies and makers
Solution Approach 1:
The patent divides customized objects into standardizable modular parts. This allows small companies to use affordable standard 3D printers while maintaining customization capability through parametric modeling and selective assembly of modular components, reducing overall production cost.
