Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If compression technique is used to transmit massive data, then data transmission rate is improved, but transmission delay increases and real-time performance deteriorates
Solution Approach 1:
The patent extracts and removes the compression and channel coding processes from the transmission system. By using millimeter wave or terahertz wave communication with inherently high bandwidth, the system transmits uncompressed HD video data directly, eliminating the time-consuming compression/decompression cycle and achieving both high transmission rate and real-time performance.
Solution Approach 2:
The patent changes the fundamental transmission parameter from conventional RF frequencies to millimeter wave or terahertz waves, which provide vastly superior bandwidth. This parameter change enables uncompressed giga-bit data transmission without the need for compression techniques, thereby eliminating transmission delay while maintaining high speed.
2Reliability
If compression and channel coding techniques are used, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent removes the power-intensive compression and channel coding modules from the mobile communication terminal. By leveraging the high bandwidth of millimeter wave/terahertz communication, the system achieves reliable uncompressed transmission without requiring complex error correction coding, thereby dramatically reducing power consumption.
3Adaptability or versatility
If MIMO technology with 5 GHz band is used, then transmission under NLOS conditions is enabled, but device size increases and power consumption increases
Solution Approach 1:
The patent changes the operating frequency to millimeter wave or terahertz bands, which provide sufficient bandwidth for uncompressed HD video transmission. This parameter change enables single-channel or simplified MIMO implementations that achieve giga-bit data rates without requiring large-scale antenna arrays, thereby reducing device size while maintaining NLOS transmission capability through the inherent properties of the higher frequency waves.
