Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional multilayer PCB production method is used, then manufacturing capability is achieved, but production cost increases and device complexity increases
Solution Approach 1:
The patent combines multiple specialized machines (etching machine, drilling machine, plating machine) into a single integrated PCB production apparatus that can perform all operations sequentially on the same device, thereby reducing device complexity while maintaining manufacturing capability
Solution Approach 2:
The PCB production apparatus is designed with multi-functional capability to perform etching, drilling, plating, and other PCB manufacturing operations using a single device, eliminating the need for multiple specialized machines and reducing overall system complexity
2Productivity
If existing printing technologies are used, then production speed is improved, but manufacturing precision deteriorates due to defects
Solution Approach 1:
The patent incorporates a database that stores optimal printing parameters based on material characteristics, age, and environmental conditions. The system uses feedback from material properties and environmental sensors to automatically adjust printing parameters, ensuring high manufacturing precision while maintaining fast production speed
Solution Approach 2:
The system dynamically changes printing parameters (such as temperature, pressure, speed) based on material characteristics and environmental conditions stored in the database, optimizing both production speed and printing quality to prevent defects
3Manufacturing precision
If manual assembly process is used, then manufacturing precision is maintained, but productivity decreases
Solution Approach 1:
The patent implements automated component placement functionality within the PCB production apparatus, where the system performs assembly operations automatically using programmed sequences and robotic mechanisms, eliminating manual labor while maintaining precision through computer control
Data Source
AI summary
An apparatus is configured to print a circuit board using conductive and nonconductive printing materials in accordance with parameters. A database stores information correlating characteristics of printing materials with shelf life and/or age of the printing materials, and/or environmental conditions. The apparatus either prompts operator to make printing parameter adjustments or automatically optimizes printing parameters based on information stored in the database and the environmental conditions. The apparatus optionally further optimizes printing parameters based on age of a print head and positioning mechanisms.
