Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional trigger operations on display interface are used for control, then device complexity remains low, but ease of operation deteriorates due to requiring manual interaction
Solution Approach 1:
The patent replaces mechanical button pressing or touchscreen triggering with acoustic wave-based control. Sound detection modules detect acoustic waves from the user's voice or gestures, converting acoustic energy into control signals that trigger device operations, thereby eliminating the need for manual interface interaction.
Solution Approach 2:
The patent introduces acoustic waves as an intermediary between the user and the device control system. Instead of direct manual operation, the user generates acoustic waves (through speech or gestures) that are detected by sound detection modules, which then translate these waves into control instructions, serving as a mediating layer that simplifies user interaction.
2Ease of operation
If hands-free control is implemented through wearable devices, then ease of operation improves, but device complexity increases due to additional sensors and processing
Solution Approach 1:
The patent makes the wearable device universal by integrating multiple functions into a single device. The wearable device not only detects acoustic waves for control purposes but also serves as a communication bridge between the user and the target device, combining sensing, processing, and transmission functions in one unit that can work with multiple different target devices.
Solution Approach 2:
The patent merges the sound detection module, angle calculation unit, and control signal transmission capabilities into an integrated wearable device. This consolidation combines multiple functional components into a single wearable unit, reducing the overall system complexity compared to having separate devices for each function.
3Ease of operation
If sound detection modules are used to determine relative angle, then ease of operation improves through intuitive control, but measurement precision may deteriorate due to acoustic wave interference
Solution Approach 1:
The patent implements feedback mechanisms where the wearable device continuously monitors acoustic wave patterns and adjusts its angle calculations based on detected variations. By providing real-time feedback on the detected acoustic signals and recalculating relative angles dynamically, the system compensates for interference and maintains measurement accuracy despite challenging acoustic environments.
Solution Approach 2:
The patent uses multiple sound detection modules (excessive sensing) to detect acoustic waves from different positions. By having redundant detection points, the system can cross-validate signals and filter out interference, achieving more precise angle measurements than would be possible with a single detector, thereby overcoming the precision limitations in noisy environments.
