Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If each ophthalmic lens designer has its own designs and each lab has its own apparatus, then design flexibility and manufacturing capability are maintained, but the complexity of adaptation and integration increases significantly
Solution Approach 1:
The patent implements a universal data exchange standard that enables different lens designers and laboratories to interoperate through a common interface. The standardized data format allows any laboratory apparatus to process designs from any lens designer without requiring custom adaptation, thus maintaining design flexibility while eliminating interface complexity.
Solution Approach 2:
The patent introduces a standardized data exchange format as an intermediary layer between lens designers and manufacturing laboratories. This intermediary standardizes the communication protocol, allowing diverse systems to exchange information without direct customization, thereby preserving individual system versatility while reducing integration complexity.
2Productivity
If manufacturing process data are calculated prior to the beginning of the manufacturing process, then initial production planning is enabled, but the precision is reduced and calculation resources are wasted
Solution Approach 1:
The patent implements a dynamic recalculation mechanism that allows manufacturing process data to be updated and recalculated during the manufacturing process based on measured process data. This dynamic approach enables both initial production planning and subsequent precision adjustments, resolving the contradiction between early planning efficiency and final manufacturing precision.
Solution Approach 2:
The patent incorporates a feedback loop where measured process data during manufacturing is used to recalculate and adjust manufacturing process data. This feedback mechanism ensures that initial planning benefits are maintained while allowing precision improvements through real-time data adjustment, preventing resource waste by only recalculating when necessary.
3Adaptability or versatility
If each ophthalmic designer has its own data formats and each lab has its own tools, then design independence is maintained, but the consistency between lenses from different labs deteriorates
Solution Approach 1:
The patent implements a standardized data format that acts as a universal copy mechanism between different design systems and manufacturing laboratories. Each designer can maintain independent design tools, but the standardized format ensures that the essential design information is consistently represented and interpreted across all laboratories, guaranteeing lens consistency while preserving design independence.
4Reliability
If two transmission-reception steps are necessary to start the calculation, then data validation opportunities are provided, but the process complexity and time increase
Solution Approach 1:
The patent implements preliminary validation of data during the transmission process itself, rather than requiring separate validation steps. The standardized data format includes built-in validation rules that are checked automatically during transmission, providing data validation opportunities while minimizing additional process time by integrating validation into the existing workflow.
