Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If effective bit numbers are stored by allocating bits according to their storage bit width, then the storage method is simple and direct, but a larger storage bit width is occupied
Solution Approach 1:
The patent changes the storage parameter from storing absolute effective bit numbers to storing differential values between adjacent effective bit numbers. This parameter transformation reduces the storage bit width required, as differential values typically have smaller magnitudes and can be represented with fewer bits compared to the original effective bit numbers.
Solution Approach 2:
The patent segments the storage approach by dividing data into blocks and processing effective bit numbers in groups. By segmenting the storage problem into block-level differential calculations, the system achieves more efficient bit width utilization while maintaining the simplicity of the storage method.
2Reliability
If a larger storage bit width is allocated to store effective bit numbers, then all effective bit numbers can be stored without loss, but storage efficiency decreases
Solution Approach 1:
The patent transforms the storage parameter from absolute values to differential values, which preserves the information content while reducing the bit width required. This parameter change maintains storage accuracy because the differential values can be used to reconstruct the original effective bit numbers, while simultaneously improving storage efficiency by reducing the allocated bit width.
3Productivity
If differential calculation is performed on effective bit numbers to reduce storage bit width, then storage efficiency is improved, but the storage method becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing data into blocks and performing differential calculations at the block level. This segmentation approach reduces the overall complexity compared to processing individual effective bit numbers, as it allows for batch processing and reduces the frequency of differential calculations, thereby improving storage efficiency while keeping the method manageable.
