Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar systems are used for tracking objects and entities in smart home environments, then location and movement detection precision is improved, but device complexity increases
Solution Approach 1:
The patent introduces electronic tags as intermediary devices that attach to objects to be tracked. These tags contain transponders that respond to radar signals, simplifying the overall system architecture by separating the tracking function into a dedicated component rather than requiring complex integrated systems.
Solution Approach 2:
The system divides the smart home environment into multiple zones with multiple radar units, each handling specific areas. This segmentation allows the complex tracking problem to be broken down into simpler, manageable segments that can be processed independently.
2Adaptability or versatility
If multiple radios are integrated into compact smart devices for communication, then communication versatility is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple communication radios (radar, Wi-Fi, Bluetooth, Zigbee) into single integrated smart devices. This merging approach allows diverse communication protocols to coexist in compact form factors, enabling versatile inter-device communication without requiring separate dedicated hardware for each protocol.
Solution Approach 2:
Smart devices are designed with multi-functional communication capabilities, where a single device can operate across multiple communication protocols and modes. This universality allows devices to adapt to different communication requirements dynamically, reducing the need for specialized single-function devices.
3Reliability
If radar signals are used for communication between devices, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The radar system operates in periodic pulses rather than continuous transmission. Radar signals are sent at intervals, allowing the system to maintain reliable detection and communication capabilities while significantly reducing average power consumption compared to continuous operation.
Solution Approach 2:
The system dynamically adjusts radar transmission parameters such as pulse frequency, power level, and duty cycle based on environmental conditions and detection requirements. This dynamic operation allows the system to optimize the balance between communication reliability and energy consumption in real-time.
