Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single ophthalmic laser treatment apparatus is used for various disease cases, then device versatility is improved, but ease of operation deteriorates due to cumbersome parameter adjustments
Solution Approach 1:
The control unit stores pre-configured irradiation conditions for multiple treatment modes in advance. When a treatment mode is selected, the corresponding parameters (irradiation energy, focus shift position, pulse duration) are automatically loaded, eliminating the need for operators to manually adjust settings for each disease case.
Solution Approach 2:
The system automatically changes irradiation parameters based on the selected treatment mode. The control unit modifies key parameters such as irradiation energy, focus shift position, and pulse duration according to the stored configuration for each specific treatment, allowing versatile operation without manual parameter adjustment.
2Adaptability or versatility
If manual adjustment of irradiation conditions is required for different disease cases, then adaptability is improved, but reliability deteriorates due to incorrect settings
Solution Approach 1:
The control unit pre-configures and stores accurate irradiation conditions for each treatment mode before use. This preliminary setup ensures that when treatment begins, the correct parameters are already in place, eliminating human error in parameter selection and ensuring reliable treatment outcomes.
Solution Approach 2:
The control unit provides feedback to the operator by displaying the selected treatment mode and confirming the loaded parameters. This feedback mechanism ensures that the correct irradiation conditions are applied and allows for verification before treatment starts, preventing incorrect settings.
3Adaptability or versatility
If operators manually set irradiation parameters for each treatment mode, then device versatility is maintained, but productivity deteriorates due to time-consuming adjustments
Solution Approach 1:
Irradiation conditions for all treatment modes are pre-configured and stored in the control unit before the treatment session begins. This preliminary preparation eliminates the need for time-consuming manual adjustments during treatment, allowing operators to quickly switch between different disease cases without reconfiguring parameters.
Solution Approach 2:
The manual mechanical process of adjusting irradiation parameters is replaced with an automated electronic system. The control unit electronically loads the appropriate parameters based on the selected treatment mode, significantly reducing the time required to prepare for each treatment case and improving overall productivity.
