Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If physical buttons are used for device control, then device functionality is achieved, but production costs increase and design flexibility is limited
Solution Approach 1:
The patent replaces mechanical buttons with a UWB-based wireless communication system. The UWB module transmits and receives control signals wirelessly, eliminating the need for physical mechanical buttons. This substitution reduces production costs and simplifies device structure while maintaining full control functionality through wireless signal processing.
Solution Approach 2:
The patent extracts the button functionality from the physical device structure and relocates it to a wireless communication module. By taking out the mechanical buttons and implementing their functions through UWB signal processing, the device achieves cost reduction and design flexibility without sacrificing operational capability.
2Adaptability or versatility
If physical buttons are included in the device, then control functions are available, but device design flexibility is reduced
Solution Approach 1:
The patent replaces mechanical buttons with a UWB-based wireless communication system. The UWB module transmits and receives control signals wirelessly, eliminating the need for physical mechanical buttons. This substitution reduces production costs and simplifies device structure while maintaining full control functionality through wireless signal processing.
Solution Approach 2:
The UWB module serves multiple functions: it acts as both a communication interface and a control input mechanism. By making the UWB module universal, the device can perform various control operations (power on/off, volume adjustment, capture functions) without requiring dedicated physical buttons for each function, thereby enhancing design flexibility.
3Ease of manufacture
If UWB signal pattern analysis is used instead of physical buttons, then production costs are reduced, but signal analysis complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the UWB module continuously monitors and analyzes incoming control signals. The system compares received signal patterns against predefined templates to identify user intentions (short press, long press, swipe operations). This feedback-based approach automates the signal analysis process, reducing manual intervention while maintaining accurate control function recognition.
Solution Approach 2:
The patent pre-configures signal patterns and their corresponding control functions during device initialization. By performing preliminary setup of signal recognition templates and control mappings, the complex signal analysis work is prepared in advance, reducing real-time processing complexity and enabling faster, more efficient signal interpretation during actual device operation.
