Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the semiconductor device performs a write copy operation by receiving external data, then the pattern data can be stored in the core region, but power consumption increases and the operation becomes less efficient
Solution Approach 1:
The patent uses a pipe circuit to store pattern data as a copy during write operations, which can then be referenced during write copy operations without requiring external data reception. This copying mechanism allows the device to perform write copy operations using internally stored pattern data, reducing power consumption while maintaining operational efficiency
Solution Approach 2:
The patent performs preliminary storage of pattern data in the pipe circuit during write operations. This preliminary action allows the pattern data to be readily available for subsequent write copy operations, eliminating the need to receive external data and thereby reducing power consumption while improving operational efficiency
2Adaptability or versatility
If the semiconductor device receives external data for write copy operations, then accurate pattern data can be stored, but the device cannot store pattern data without external data input
Solution Approach 1:
The pipe circuit stores a copy of the pattern data during write operations, preserving the original data while creating a reusable copy. This copying approach enables the device to perform write copy operations using the stored copy without receiving external data, thereby improving adaptability while maintaining data accuracy through the preserved copy
Solution Approach 2:
The device uses its own internally stored pattern data from the pipe circuit to perform write copy operations, rather than requiring external data input. This self-service capability allows the device to store and reproduce pattern data independently, improving adaptability while ensuring accuracy through the use of previously verified pattern data
3Productivity
If the semiconductor device performs write operations with external data reception, then data can be stored in the core region, but the operation time and complexity increase
Solution Approach 1:
The pipe circuit stores a copy of the pattern data during write operations, enabling subsequent write copy operations to proceed without external data reception. This copying mechanism accelerates write copy operations by eliminating the data reception step, thereby improving productivity while reducing operation time
Solution Approach 2:
The pattern data is preliminarily stored in the pipe circuit during the write operation phase. This preliminary action prepares the data for rapid retrieval and use in write copy operations, reducing the time required for subsequent operations while maintaining high data storage speed through efficient data preparation
