Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical Braille writers are used for writing, then tactile input capability is provided, but the ability to convert Braille input into digital formats is limited
Solution Approach 1:
The patent introduces sensors as intermediary devices that detect the position of Braille writer keys and convert mechanical movements into electrical signals. These sensors act as a mediator between the mechanical Braille writer and the digital processing system, enabling data conversion without requiring direct integration between mechanical and digital components.
Solution Approach 2:
The patent replaces the need for complex mechanical encoding mechanisms with electronic sensor-based detection. Instead of using mechanical levers and linkages to directly encode Braille patterns, the system uses sensors to detect key positions and electronically translates them into digital Braille data, simplifying the overall system architecture.
2Productivity
If sensors are added to capture embossing motions, then digital data capture is enabled, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional system where the same sensor array serves multiple purposes: detecting key positions, determining embosser head movements, and capturing timing information. This universal approach allows a single sensor system to handle various detection tasks, reducing the need for separate specialized components for each function.
Solution Approach 2:
The system uses the existing mechanical structure of the Braille writer (the movement of keys and embosser head) to generate the detection signals themselves. The mechanical components' natural movements during normal operation are what the sensors detect, meaning the system's normal operation automatically provides the detection data without requiring separate actuation mechanisms.
3Speed
If real-time translation is implemented, then immediate digital output is achieved, but processing requirements increase
Solution Approach 1:
The patent implements preliminary action by pre-mapping sensor signal patterns to corresponding Braille cell representations. The system is pre-configured with the relationships between sensor activations and Braille character encoding, allowing for rapid translation without requiring complex real-time computation during the actual typing process.
Solution Approach 2:
The system creates a digital copy of the mechanical Braille writing process by mapping sensor detections to corresponding digital Braille cell data. This copying approach allows the digital representation to be generated directly from the mechanical input pattern without requiring interpretation or complex processing of the underlying meaning of each input sequence.
