Wireless Device LED Pattern Synchronization for Connection Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in presenting the connection relationship and state between wirelessly connected devices in an easily understandable manner, making it difficult for users to grasp the correct connection establishment and data transmission status.
Innovation Solution
A wireless communication apparatus generates and shares an output pattern corresponding to the connection state with other devices, synchronizing the output timing to visually represent the connection status using LEDs or other output devices, allowing users to easily understand the connection relationship and state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless connection status is displayed using conventional methods (text or static icons), then the device complexity is low, but the ease of operation and user understanding of connection state is insufficient
Solution Approach 1:
The patent applies periodic action by using blinking LED lights in specific patterns (e.g., alternating blink rates between connected devices) to indicate connection status. Each device blinks its LED periodically, and the pattern of blinking (synchronized vs. unsynchronized) conveys different connection states, making it visually intuitive for users to understand connection status without complex displays.
Solution Approach 2:
The patent utilizes color changes in LED output to represent different connection states. For example, green LED indicates successful connection, red indicates disconnection, and yellow indicates connection in progress. This visual color coding system allows users to quickly grasp connection status at a glance, significantly improving ease of operation and user understanding.
2Ease of operation
If visual feedback is provided through synchronized LED patterns, then the ease of operation improves, but the loss of time for establishing and synchronizing connection increases
Solution Approach 1:
The patent implements preliminary action by pre-defining multiple LED blink patterns that correspond to different connection states before actual connection occurs. When a connection is initiated, the system simply switches to the appropriate pre-defined pattern rather than generating and synchronizing a new pattern in real-time. This reduces synchronization time significantly, as the visual feedback mechanism is already prepared and only needs to be activated with the correct parameters.
3Reliability
If the output pattern is shared and synchronized between devices, then the reliability of connection status indication improves, but the device complexity increases due to coordination requirements
Solution Approach 1:
The patent applies self-service by enabling each device to independently generate and control its own LED output pattern based on local connection state information. Instead of one device centrally controlling and transmitting complex synchronization signals to all other devices, each device autonomously determines its connection status and displays the corresponding pre-defined pattern. This eliminates the need for complex inter-device coordination while maintaining reliable and consistent visual feedback across all devices.
