Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are unable to determine the quality of wireless transmission due to increased signal interference, which leads to frame errors and retransmissions, and existing methods do not provide a clear indication of radio signal parameters such as collision error, RSSI, and data rate.
Innovation Solution
A method and device that select and indicate radio interference levels by detecting parameters like collision error, frame error, association number, RSSI, data rate, and traffic latency, using visual or audio signals, with a controller, radio signal receiver, and indicating elements like LEDs or speakers, to provide clear feedback on wireless transmission quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless devices are introduced to increase network versatility and data transfer capability, then network functionality and data transfer speed are improved, but signal interference increases leading to frame errors and retransmissions
Solution Approach 1:
The patent implements a feedback mechanism by continuously monitoring radio interference levels and providing real-time visual indicators (LEDs) to users. The system measures parameters such as signal-to-interference ratio (SIR), frame error rate, and retransmission count, then feeds this information back through illuminated indicators that change based on detected interference conditions, enabling users to adjust their wireless environment accordingly.
Solution Approach 2:
The patent introduces an intermediary device (the radio interference indicator system) that mediates between the complex wireless transmission process and the user. This intermediary monitors multiple technical parameters (SIR, frame errors, retransmissions) and translates them into simple visual indicators, allowing users to understand and respond to interference conditions without needing to interpret raw technical data.
2Adaptability or versatility
If signal interference increases due to multiple wireless devices, then network coverage and device connectivity are improved, but transmission reliability deteriorates with increased frame errors and retransmissions
Solution Approach 1:
The system provides continuous feedback on transmission quality by monitoring frame error rates and retransmission counts, displaying these conditions through LED indicators that reflect the current reliability state of wireless transmissions.
Solution Approach 2:
The patent replaces complex mechanical measurement and analysis systems with electronic signal processing and optical indication. Instead of using physical measurement tools to assess transmission quality, the system uses electronic monitoring of radio signals and converts these measurements into visual optical indicators through LEDs.
3Reliability
If users need to know transmission quality parameters such as collision error, RSSI, and data rate, then transmission reliability can be improved through informed adjustments, but system complexity increases requiring additional monitoring and indication mechanisms
Solution Approach 1:
The patent implements a multi-functional indicator system where a single LED indicator performs multiple functions: it indicates overall interference levels, frame error conditions, retransmission states, and general transmission quality. This universal indicator consolidates what would otherwise require multiple separate monitoring and display mechanisms, reducing overall system complexity while providing comprehensive transmission quality information.
Solution Approach 2:
The system monitors multiple transmission parameters (SIR, frame error rate, retransmission count, RSSI) and transforms these complex parameters into a simplified visual representation. By changing the state of the LED indicator based on different parameter thresholds, the system provides actionable quality information without requiring users to directly interpret multiple technical parameters.
4Productivity
If real-time indication of radio interference levels is implemented, then users can make timely adjustments to improve data transfer rates, but energy consumption increases due to continuous monitoring and indication
Solution Approach 1:
The patent implements periodic monitoring and indication rather than truly continuous operation. The system measures interference levels at regular intervals and updates the LED indicators accordingly, allowing the indicators to remain illuminated or change state based on detected conditions while consuming energy only during measurement and indication updates rather than maintaining constant active display.
