Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If wireless communication devices select base stations based on the strongest beacon signal, then signal strength is improved, but overcrowding occurs and quality of service deteriorates
Solution Approach 1:
The patent changes the selection parameter from beacon signal strength alone to include modulation level information. Devices now consider both signal strength and modulation level when selecting access nodes, allowing them to avoid overloaded nodes even if those nodes have strong beacon signals. This parameter expansion resolves the contradiction by adding a new dimension to the selection process that accounts for network load.
Solution Approach 2:
The patent implements feedback mechanisms where access nodes provide status information including modulation levels to wireless devices. This feedback loop allows devices to make informed selection decisions based on current network conditions, preventing overcrowding by directing traffic away from already-loaded nodes. The feedback enables dynamic adaptation to changing network states.
2Ease of operation
If multiple devices connect to the same base station with the strongest signal, then connection establishment is simplified, but data transfer rates decrease due to overcrowding
Solution Approach 1:
The selection criteria are expanded to include modulation level as an additional parameter beyond signal strength. This maintains the simplicity of automatic selection while improving performance by considering network load conditions. The enhanced parameter set enables better data transfer rates without requiring manual intervention from users.
3Productivity
If wireless access nodes operate at high modulation levels, then data transfer efficiency is improved, but quality of service deteriorates when nodes become overcrowded
Solution Approach 1:
The patent enables dynamic modulation level selection where access nodes can adjust their operating modulation levels based on current load conditions. When nodes are lightly loaded, they can operate at higher modulation levels for maximum efficiency. When overloaded, devices can be directed to nodes with lower modulation levels or available capacity, maintaining quality of service while preserving data transfer efficiency where possible.
