Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack efficient control over network scan parameters, leading to unnecessary battery consumption and inefficient scans due to fixed scanning periods, especially in mobile devices transitioning between jurisdictions with different frequency spectrum regulations.
Innovation Solution
Implementing a method to dynamically adjust the frequency and duration of network scans based on conditions such as movement, battery level, and regulatory changes, using a processor and monitoring module to aggregate scan requests and configure optimal scan parameters, allowing for intelligent scanning in IEEE 802.11 networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed scanning periods are used for network scans, then network connectivity can be maintained, but battery consumption increases unnecessarily
Solution Approach 1:
The patent implements dynamic scan parameter adjustment where the wireless device changes scan frequency and duration based on real-time conditions such as movement detection, battery level, and network status. Instead of fixed scanning periods, the system adaptively modifies scan behavior to maintain connectivity while reducing unnecessary scans during stable conditions, directly resolving the contradiction between reliability and energy consumption.
Solution Approach 2:
The system changes scan parameters (frequency, duration, intensity) based on detected conditions. When movement is detected or battery level drops, the scan parameters are adjusted accordingly. This parameter adaptation allows the system to maintain network connectivity when needed while minimizing energy consumption during stable periods, addressing the technical contradiction effectively.
2Speed
If frequent network scans are conducted to maintain connectivity, then network responsiveness improves, but energy consumption increases
Solution Approach 1:
The patent implements periodic scanning with variable intervals rather than continuous or fixed-period scanning. The system conducts scans at optimized intervals based on current conditions, performing frequent scans only when necessary for responsiveness while extending intervals during stable conditions to conserve energy. This conditional periodic action resolves the contradiction between speed and energy consumption.
Solution Approach 2:
The system performs partial scanning actions rather than complete frequent scans. When full connectivity maintenance is not required, the system reduces scan intensity or duration, performing only the necessary portion of the scan operation. This partial action maintains adequate responsiveness while significantly reducing energy consumption compared to full frequent scans.
3Ease of manufacture
If network scans are performed without parameter optimization, then implementation is simple, but scan efficiency decreases
Solution Approach 1:
The patent implements self-service through automated condition monitoring and parameter adjustment. The wireless device autonomously detects its own state (movement, battery level, network status) and automatically adjusts scan parameters without requiring manual configuration or complex external control systems. This self-service approach maintains implementation simplicity while dramatically improving scan efficiency through optimized parameter selection.
Solution Approach 2:
The system incorporates feedback mechanisms where scan results and device state information are continuously monitored and used to adjust subsequent scan parameters. This feedback loop enables the system to learn from past scan outcomes and optimize future scan behavior, improving efficiency without requiring complex pre-programming or manual intervention, thus maintaining ease of implementation.
