Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices share the same wireless network, then network coverage and accessibility are improved, but communication congestion and interference increase
Solution Approach 1:
The patent segments the wireless network into multiple virtual channels or logical networks, allowing simultaneous transmissions on different segments without interference. This enables multiple devices to share the network while maintaining individual communication paths, thus improving overall communication efficiency despite increased device density.
Solution Approach 2:
The patent introduces additional dimensions for resource allocation beyond traditional time and frequency domains, such as spatial dimensions through MIMO (Multiple Input Multiple Output) technology. By utilizing multiple antennas and spatial streams, the system creates parallel communication paths that reduce congestion and interference while maintaining network coverage.
2Productivity
If wireless resources are allocated to multiple users simultaneously, then network throughput is improved, but resource allocation complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation where allocation parameters are continuously adjusted based on real-time network conditions, user requirements, and channel quality. This dynamic approach allows the system to optimize throughput by allocating resources to users with the best channel conditions while automatically adapting to changing conditions, reducing the need for complex manual management.
Solution Approach 2:
The patent incorporates feedback mechanisms where users report channel quality, buffer status, and reception conditions back to the base station. This feedback enables automatic adjustment of allocation parameters, allowing the system to maintain high throughput through adaptive modulation, coding, and resource allocation without requiring complex centralized control.
3Reliability
If transmission power is increased to overcome interference, then signal reliability is improved, but energy consumption and interference to other users increases
Solution Approach 1:
The patent applies local quality by allocating different transmission power levels to different users and channels based on their specific requirements and channel conditions. Users with good channel conditions receive lower power allocations, while users in poor conditions receive targeted power boosts only where needed. This localized approach maintains signal reliability for each user while minimizing overall energy consumption and reducing interference to other users.
