Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multicast/broadcast uses an antenna having a quasi-omni pattern, then the transmitting device can have a substantially constant antenna gain in various directions, but sufficient transmission quality cannot be achieved
Solution Approach 1:
The patent segments the coverage area into multiple regions and uses multiple transmitting devices, each responsible for specific regions. This allows each device to use directional antennas with higher gain for its assigned region, while collectively providing comprehensive coverage that mimics omnidirectional capability.
Solution Approach 2:
The patent combines multiple transmitting devices to work together as a unified system. By coordinating their transmissions and assigning different regional responsibilities, the system achieves both high transmission quality (through directional antennas) and omnidirectional coverage (through multiple devices).
2Speed
If high data transmission speeds are achieved in part of the communication route, then data transmission is fast in that segment, but data transmission speeds slow down due to the slow data transmission characteristics of a surrounding network
Solution Approach 1:
The patent segments the network into multiple independent communication paths with different transmitting devices. Each segment can operate at optimal speeds for its characteristics, preventing a single slow segment from bottlenecking the entire system. The system can route data through multiple segments in parallel.
Solution Approach 2:
The patent introduces spatial diversity by using multiple transmitting devices at different locations. This creates multiple dimensional paths for data transmission, allowing the system to bypass slow segments by routing through alternative spatial paths, thus maintaining overall high transmission speeds.
