Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating elements are provided for selecting mode, setting parameters, and controlling operation, then the dosing device achieves functional versatility, but the operation becomes cumbersome and complex
Solution Approach 1:
The patent combines multiple operating elements (mode selection, parameter setting, and operation control) into a single integrated button. This single button can trigger different functions depending on the current display indication, thereby maintaining functional versatility while significantly simplifying the user interface and reducing operational complexity.
Solution Approach 2:
The display device provides visual feedback to the user about the current operating state and the next meaningful displacement of the displacement element. This feedback mechanism guides the user through the operation sequence, allowing a single button to control complex functions by displaying the required operational steps clearly.
2Device complexity
If a single button is used to control liquid dispensing and intake, then the device complexity is reduced, but the user cannot recognize the next meaningful operating step
Solution Approach 1:
The display device provides continuous visual feedback to the user about the current operating state and the next meaningful displacement of the displacement element. This feedback mechanism compensates for the limited control elements by clearly displaying the required operational steps, ensuring the user always knows what to do next.
Solution Approach 2:
The display device uses different visual indicators (such as color changes or different display patterns) to indicate different operating states and the next meaningful displacement. This visual coding system allows the single button to control complex functions while providing clear, intuitive feedback to the user about the current and next operational steps.
3Loss of information
If the display shows readiness for exposure, then the user knows the device is ready, but the readiness for submission is not displayed
Solution Approach 1:
The display device provides comprehensive visual feedback about the current operating state, including readiness for both exposure and submission. This feedback mechanism ensures the user is always informed about the device's state, eliminating ambiguity and improving operational clarity.
Solution Approach 2:
The display device uses different visual indicators to show different readiness states (exposure readiness vs. submission readiness). By using distinct visual codes, the system provides clear information about the current operational state without increasing the number of physical controls.
