Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual lens emulation is performed using conventional methods, then lens emulation functionality is achieved, but the operation becomes complex and difficult to use
Solution Approach 1:
The patent creates a simplified copy of lens characteristics through aberration tables that store pre-calculated aberration data. Instead of requiring users to manually set complex aberration parameters, the system copies the optical characteristics of different lenses into standardized tables that can be easily selected and applied, transforming a complex parameter-setting task into a simple selection process.
Solution Approach 2:
The patent performs preliminary calculation and storage of aberration data by pre-computing aberration tables for various lens types and conditions. This preliminary action eliminates the need for real-time complex calculations during lens emulation, allowing users to simply select from pre-prepared aberration profiles rather than dealing with the underlying mathematical complexity.
2Measurement precision
If multiple lens types are emulated with full parameter control, then emulation accuracy is improved, but the time required for setup and operation increases
Solution Approach 1:
The patent pre-calculates and stores aberration data for multiple lens types in standardized tables during the product development phase. This preliminary action ensures that when users need to emulate different lenses, they can immediately select from pre-prepared accurate profiles without spending time on complex parameter calculations, thus maintaining high emulation accuracy while minimizing setup time.
Solution Approach 2:
The patent transforms the continuous range of possible aberration parameters into discrete, standardized aberration table entries. By changing parameters from continuous user-adjustable values to discrete pre-defined table selections, the system maintains emulation accuracy across multiple lens types while dramatically reducing the time required for parameter setting and adjustment.
3Manufacturing precision
If comprehensive aberration parameters are manually configured, then lens emulation precision is improved, but the operation becomes more difficult
Solution Approach 1:
The patent copies the complex multi-parameter aberration characteristics of physical lenses into standardized aberration tables with simplified identifiers. This copying process preserves the precision of lens emulation by maintaining the underlying aberration data while presenting a simplified interface where users can select lens types without manually configuring each aberration parameter, thus achieving both precision and ease of operation.
Solution Approach 2:
The patent introduces aberration tables as an intermediary layer between the user and the complex aberration parameters. These tables act as a mediator that translates simple lens type selections into the appropriate combination of aberration parameters, allowing users to achieve precise lens emulation without directly interacting with the complex parameter configuration, thereby improving both precision and ease of operation simultaneously.
