The development of processes and systems that enable remote research, development, and production tasks, including on-site manufacturing of PCBs using additive manufacturing, which involves remote design processes, automated and manual systems, and a combination of equipment to reduce the need for specialized facilities and materials, allowing for the production of emergency repair equipment and immediate upgrades at remote locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional PCB manufacturing methods are used, then manufacturing precision and reliability are maintained, but acquisition lead time increases and on-site production capability is lost
Solution Approach 1:
The patent segments the PCB manufacturing process into modular components that can be performed sequentially using different additive manufacturing techniques. The substrate is built first, then conductive traces are added separately, followed by component mounting. This segmentation enables the process to be broken down into steps that can be executed with simpler, more portable equipment at remote locations, reducing acquisition lead time while maintaining production capability.
Solution Approach 2:
The patent transitions from traditional planar PCB manufacturing to three-dimensional additive manufacturing processes. By building PCBs in multiple layers with conductive traces deposited on substrate surfaces and within embedded channels, the invention enables on-site production using vertical stacking and layer-by-layer construction, fundamentally changing the manufacturing dimensionality to enable portability and on-site fabrication.
2Manufacturing precision
If specialized PCB fabrication facilities are used, then manufacturing precision is maintained, but device complexity and facility requirements increase
Solution Approach 1:
The patent employs additive manufacturing systems that can perform multiple functions: substrate deposition, conductive trace formation, component mounting, and encapsulation. A single multi-functional AM platform replaces traditional specialized PCB fabrication facilities, reducing device complexity and facility requirements while maintaining manufacturing precision through integrated multi-mode operation.
Solution Approach 2:
The patent merges traditionally separate PCB manufacturing processes (substrate fabrication, trace deposition, component assembly) into a single integrated additive manufacturing system. By combining these functions in one platform, the invention reduces the complexity of facility requirements while maintaining precision through unified process control and automated multi-step operation.
3Manufacturing precision
If single-use AM printers are used, then specific PCB applications are achieved, but adaptability and versatility are reduced
Solution Approach 1:
The patent employs an adaptive AM system that can dynamically adjust its operation mode based on the specific PCB application requirements. The system can switch between different deposition techniques, layer configurations, and material properties in real-time, enabling both high-precision application-specific fabrication and versatility across different PCB types without requiring dedicated single-use printers for each application.
