Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional remote control devices are used, then device control functionality is achieved, but physical interaction and aiming are required which reduces user convenience
Solution Approach 1:
The patent replaces the mechanical aiming and pointing system with a voice-based control system. The voice-controlled device uses audio processing to detect and interpret spoken commands, substituting the mechanical interaction (pointing the remote at the device) with acoustic interaction (speaking commands). This eliminates the need for physical aiming while maintaining control functionality.
Solution Approach 2:
The patent introduces voice commands as an intermediary between the user and the controlled device. Instead of direct mechanical interaction through pointing, the user speaks commands that are processed by the voice-controlled device, which then translates them into appropriate control signals. This intermediary layer simplifies the user's interaction while expanding control capabilities.
2Area of stationary object
If infrared LEDs emit light in all directions, then wide-area coverage is achieved, but infrared light dispersion may reduce intensity in specific directions
Solution Approach 1:
The patent segments the infrared LED system into multiple individual LEDs positioned at different locations and orientations within the device housing. Each LED emits infrared light in a specific direction, and collectively they provide wide-area coverage. This segmentation allows the system to maintain high intensity in multiple directions simultaneously rather than dispersing a single beam.
Solution Approach 2:
The patent applies local quality by positioning infrared LEDs at specific locations with specific orientations to target different areas. Each LED is strategically placed to cover a particular zone, ensuring that infrared light intensity is optimized for each local area while collectively achieving comprehensive wide-area coverage throughout the room.
