Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mechanical keyboards use binary key functions, then the device structure remains simple, but the functionality is limited and requires multiple key presses for complex actions
Solution Approach 1:
The key state component dynamically changes between actuated and unactuated states, allowing the keyboard to transition between different functional modes. This dynamic state change enables a single key to perform multiple functions based on its current state, resolving the contradiction between limited binary functionality and the need for complex actions.
Solution Approach 2:
The patent changes the state parameter of the key state component (between actuated and unactuated) to alter key functionality. By modifying this state parameter, the keyboard achieves multiple functions per key without requiring additional physical keys or complex structural changes.
2Productivity
If multiple key presses are required for complex actions, then the keyboard structure remains simple, but the operation efficiency decreases and more time is required
Solution Approach 1:
The dynamic key state component allows users to access alternate functions with a single key press by changing the key state beforehand. This eliminates the need for multiple sequential key presses, thereby improving operation efficiency and reducing the time required to perform complex actions.
Solution Approach 2:
The system performs preliminary action by changing the key state component to prepare alternate functions in advance. This preliminary state change allows subsequent key presses to execute complex actions more efficiently, reducing the time required for operation.
3Ease of operation
If mode changes are required for dual language input, then the keyboard structure remains simple, but the ease of operation decreases and more time is required
Solution Approach 1:
The key state component dynamically switches between language modes, allowing users to input dual languages efficiently without physical mode changes. This dynamic state switching improves ease of operation by enabling seamless transition between language inputs with simple key presses.
Solution Approach 2:
The keyboard achieves multi-functionality by enabling a single key to serve multiple language functions through the key state component. This universal design allows the same physical key to input different languages based on its state, eliminating the need for separate mode change procedures.
4Ease of operation
If tactile feedback is provided for function modifications, then the user interface efficiency improves, but the device complexity increases
Solution Approach 1:
The key state component provides tactile feedback to indicate when alternate functions are active. This feedback mechanism improves user interface efficiency by giving users immediate sensory confirmation of the current key state, allowing them to operate the keyboard more efficiently without needing to visually check settings.
