Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional contact-based chip programming method is used, then programming can be completed with existing equipment, but the process involves multiple steps including installation, programming, verification, and disassembly which makes it cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical contact-based programming system with an optical wireless system. Light signals are used to transmit programming data to the chip without physical contact, eliminating the need for sockets, fixtures, and manual installation/removal operations. This substitution directly resolves the contradiction by making the operation simpler (no physical handling) and faster (direct optical transmission).
Solution Approach 2:
The patent introduces light as an intermediary medium to transfer programming information between the programmer and the chip. Instead of direct electrical contact through pins and sockets, light signals carry the programming data wirelessly, simplifying the interaction process and eliminating mechanical complexity while maintaining data transmission functionality.
2Reliability
If traditional chip programming method is used, then reliable data transmission can be achieved through electrical contact, but the process requires chip installation and disassembly which reduces programming efficiency
Solution Approach 1:
The patent replaces the mechanical electrical contact system with an optical transmission system. Light signals provide reliable data transmission without requiring physical connection, thereby maintaining programming reliability while dramatically improving efficiency by eliminating installation and disassembly steps.
Solution Approach 2:
The patent implements preliminary encoding of programming data into light signals before transmission. The programmer pre-processes the data and modulates it onto light carriers, ensuring reliable transmission is established before the actual programming operation begins, which maintains reliability while streamlining the overall process.
