Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate input apparatus and receiver are used to transmit content, then signal transmission is achieved, but device complexity increases and real-time confirmation becomes difficult
Solution Approach 1:
The patent combines the input apparatus and receiver into a single integrated device. The input apparatus includes both the input unit for detecting user input and the receiver for receiving transmitted signals, eliminating the need for separate devices and enabling real-time content confirmation on the display.
Solution Approach 2:
The integrated apparatus performs multiple functions: it serves as both an input device for user interaction and a receiver for signal transmission. This multi-functional design reduces the number of separate components needed while maintaining real-time content display capabilities.
2Adaptability or versatility
If multiple input units are provided for different input modes, then input versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic switching between different input modes through a mode switching unit. This allows the apparatus to adapt between first input mode (using first input unit) and second input mode (using second input unit) based on user needs, providing versatility without requiring permanently active multiple input configurations.
Solution Approach 2:
The input apparatus is segmented into distinct input units (first input unit and second input unit) that can be selectively activated. This segmentation allows each unit to be optimized for specific input functions while the overall system maintains versatility through selective mode switching.
3Reliability
If transmitting sensors are always active for real-time transmission, then real-time content display is achieved, but energy consumption increases
Solution Approach 1:
The transmitting sensors operate periodically based on the input mode rather than continuously. The mode switching unit controls when the first or second transmitting sensor is activated, reducing energy consumption by keeping sensors inactive during periods when their specific input mode is not being used.
Solution Approach 2:
The apparatus automatically switches between transmitting sensors based on the active input mode without requiring external control. This self-service mechanism ensures real-time transmission capability is maintained while minimizing energy consumption by activating only the necessary sensor for the current operational state.
