Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional input tools are used without function mapping, then the device structure remains simple, but user convenience and interaction efficiency deteriorate
Solution Approach 1:
The system performs preliminary action by pre-defining multiple function templates (e.g., copy, paste, undo, redo, screenshot) that can be mapped to button inputs. This allows the device to anticipate user needs and provide pre-configured functional mappings, improving ease of operation without requiring complex real-time processing.
Solution Approach 2:
The patent introduces an intermediary layer (the function mapping system) between the button input and the device functions. This intermediary automatically matches button inputs with predefined functions based on context, shielding users from system complexity while enabling sophisticated interactions.
2Measurement precision
If multiple signal types are used for button input detection, then input accuracy and function mapping precision improve, but device complexity increases
Solution Approach 1:
The patent merges multiple signal types (electromagnetic resonance signals from the digital pen and Bluetooth Low Energy signals from the button) into a unified input detection system. By combining these signals, the system achieves higher input detection accuracy while managing complexity through integrated processing.
Solution Approach 2:
The button input system is designed with multi-functionality to detect and process different signal types (EMR and BLE). This universal detection capability allows the same button to serve multiple input methods, improving measurement precision without requiring separate detection systems for each signal type.
3Productivity
If function mapping is implemented for digital pen buttons, then user interaction efficiency improves, but ease of manufacture deteriorates
Solution Approach 1:
The function mapping system operates autonomously, automatically detecting button inputs and matching them with appropriate functions based on predefined templates. This self-service capability eliminates the need for manual configuration during manufacturing, improving interaction efficiency without significantly increasing manufacturing complexity.
Solution Approach 2:
The system enables dynamic parameter changes by allowing function mappings to be adjusted through software configuration rather than hardware modification. This flexibility improves interaction efficiency while maintaining ease of manufacture, as changes can be made without physical reassembly or complex manufacturing processes.
