Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If conventional Wi-Fi access points are used to extend wireless coverage, then coverage area is increased, but the number of devices required increases and data transmission rate remains limited

Engineering Contradiction:

Improvewireless coverage areaVSAvoidnumber of access points required

Core Design Contradiction:

Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent merges multiple communication protocols (Wi-Fi, Bluetooth, Zigbee, cellular) into a single mmWave RF repeater device. This consolidation allows one device to provide the coverage and connectivity functions that previously required multiple separate access points and extenders, thereby reducing device complexity while maintaining or improving coverage area.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The mmWave RF repeater is designed as a universal device that supports multiple communication protocols simultaneously. It can receive and forward signals from different protocols (2.4 GHz Wi-Fi, 5 GHz Wi-Fi, Bluetooth, Zigbee, cellular) and transmit them via mmWave, making a single device perform the functions of multiple specialized devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If conventional Wi-Fi protocols are used, then compatibility is maintained, but data transmission rate is limited by narrow bandwidth

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent changes the operating frequency parameter from conventional Wi-Fi frequencies (2.4 GHz, 5 GHz) to millimeter wave frequencies (mmWave). This frequency change enables significantly higher data transmission rates and bandwidth, while the device maintains compatibility with older protocols by receiving their signals and retransmitting them at the higher mmWave frequency.

Solution Approach 1:

The patent segments the communication workload across multiple protocols and frequency bands. By using mmWave for high-speed data transmission and reserving conventional protocols for device connectivity and control, the system can support a large number of IoT devices while maintaining quality-of-service requirements through protocol-specific optimization.

Solution Approach 1:

The mmWave RF repeater acts as an intermediary device between diverse communication protocols and the mmWave transmission medium. It receives signals from various protocols (Wi-Fi, Bluetooth, Zigbee, cellular), processes and converts them to mmWave format, and transmits them to receiving devices, thereby enabling device diversity without requiring each endpoint device to support all protocols.
