Solution Overview
Problem
Existing methods for producing three-dimensionally fabricated objects with conductors face limitations due to the physical properties of UV curable resins, which affect electrical characteristics and increase production costs.
Innovation Solution
A production method and device that separate the fabrication of the object and electronic device into distinct steps, allowing for the use of different UV curable resins with tailored properties in each step, thereby alleviating limitations on resin selection and reducing production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single UV curable resin is used for both the attached object and electronic device fabrication, then the production process is simplified, but the physical properties are limited and cannot be optimized for both applications
Solution Approach 1:
The patent divides the fabrication process into two separate steps: first fabricating the attached object, then fabricating the electronic device. This segmentation allows different UV curable resins to be used in each step, optimizing physical properties for each specific application while maintaining production efficiency.
2Reliability
If UV curable resin with optimized physical properties is selected for electronic device fabrication, then electrical characteristics improve, but the resin selection for attached object fabrication becomes constrained
Solution Approach 1:
By separating the fabrication into distinct steps, the patent enables independent resin selection for each application. The electronic device can use resin optimized for electrical characteristics, while the attached object can use resin with different properties suited for its specific requirements.
3Ease of manufacture
If the same resin is used throughout the fabrication process, then production cost is reduced, but the ability to optimize for specific application requirements is lost
Solution Approach 1:
The two-step fabrication process allows for application-specific resin optimization without significantly increasing production cost. Each resin can be selected and optimized for its specific use case, improving overall manufacturing precision and performance.
