Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi connection methods for smart devices often fail to automatically select the best access point based on the environment, leading to suboptimal performance due to interference and coverage issues between 2.4 GHz and 5 GHz bands.
Innovation Solution

Engineering Contradiction Analysis
1Area of stationary object
If the 2.4 GHz band is used for Wi-Fi connection, then the reception range and coverage are improved, but the communication speed decreases due to severe signal interference
Solution Approach 1:
The system dynamically selects between 2.4 GHz and 5 GHz frequency bands based on real-time environmental conditions. The processor automatically determines which band to use by evaluating signal interference levels and coverage requirements, allowing the Wi-Fi connection to adapt its operating parameters without user intervention.
Solution Approach 2:
The invention changes the frequency band parameter from fixed to variable. By allowing the system to switch between 2.4 GHz and 5 GHz bands based on environmental conditions, the patent optimizes the balance between reception range and communication speed through parameter adaptation rather than fixed configuration.
2Speed
If the 5 GHz band is used for Wi-Fi connection, then the communication speed and signal reliability are improved, but the reception range decreases due to vulnerability to diffraction and reflection
Solution Approach 1:
The system dynamically switches between frequency bands based on real-time environmental assessment. When obstacles are detected or signal interference is high, the system transitions from 5 GHz to 2.4 GHz band, and vice versa, optimizing the balance between speed and range adaptively.
Solution Approach 2:
The system continuously monitors wireless communication environment parameters including signal strength, interference levels, and coverage conditions. This feedback information is processed to automatically determine the optimal frequency band, ensuring continuous operation at peak performance without manual configuration.
3Ease of operation
If automatic Wi-Fi connection is implemented without user selection, then the ease of operation is improved, but the ability to select the best AP based on environment is lost
Solution Approach 1:
The system performs self-optimization by automatically evaluating wireless environments and selecting the best available AP without user intervention. The processor independently analyzes signal conditions, interference levels, and coverage parameters to determine optimal connection settings, eliminating the need for manual AP selection while maintaining high connection quality.
Solution Approach 2:
The system uses environmental feedback to automatically adjust connection parameters and select optimal APs. By continuously monitoring wireless conditions and using this information to make real-time decisions, the system achieves both ease of operation and high reliability through automated intelligent selection.
