Smart Key Warning Message Circular Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart key systems lack a priority control function for buffering operations in their message queue buffers, leading to unpredictable display of multiple warning messages, making it difficult for drivers to recognize and address vehicle abnormalities effectively.
Innovation Solution
A method that circularly transmits and displays multiple warning messages through a message queue buffer at predetermined intervals, with new messages being prioritized and displayed before existing ones, and the buffer operation ending when message renewal times expire, using communication methods like CAN, RS232C, RS422, RS485, USB, Bluetooth, or Ethernet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple warning messages are displayed simultaneously without priority control, then all warning information is provided to the driver, but the driver cannot sufficiently recognize the contents due to lack of systematic organization
Solution Approach 1:
The patent segments multiple warning messages into distinct display time slots within a circular buffer structure. Each warning message is allocated a specific time segment for display, allowing the system to present multiple warnings systematically rather than simultaneously. This segmentation enables the driver to recognize each warning content clearly while still receiving all warning information.
Solution Approach 2:
The patent implements periodic action by circularly displaying warning messages at predetermined intervals. The message queue buffer operates in a cyclic manner, repeatedly displaying each warning message after a set time period. This periodic display ensures that important warnings are reinforced and noticed by the driver, while maintaining a systematic and organized presentation rhythm.
2Reliability
If warning messages are displayed randomly without predetermined intervals, then all messages can be shown, but the display lacks systematic organization making recognition difficult
Solution Approach 1:
The patent applies dynamics by implementing a flexible circular buffer mechanism that can dynamically adjust the display sequence and timing of warning messages. The buffer structure allows messages to be inserted, updated, and displayed in a dynamic manner while maintaining overall systematic organization through predetermined intervals and priority-based queuing.
Solution Approach 2:
The patent utilizes parameter changes by modifying the display time, sequence, and priority parameters of warning messages based on their importance and type. The system changes these parameters systematically to ensure complete message display while maintaining organized presentation, resolving the contradiction between completeness and complexity.
3Ease of operation
If only one warning message is displayed at a time without circular buffering, then the display is simple, but additional warnings cannot be effectively communicated
Solution Approach 1:
The patent applies preliminary action by pre-organizing multiple warning messages in a circular buffer structure before display. The system prepares the sequence and timing of multiple warnings in advance, allowing them to be communicated effectively through systematic circular display while maintaining relative simplicity in the display mechanism.

AI summary
A method for displaying a warning message of a smart key system may include: a first step in which a control part of a smart key system generates two or more warning messages corresponding to two or more abnormalities/warnings, when the two or more abnormalities/warnings occur; a second step in which the control part repetitively and sequentially renews and inputs the two or more warning messages to a message queue buffer and controls the message queue buffer to buffer and output the two or more warning messages such that the two or more warning messages are circularly displayed on a display part; and a third step in which the control part ends the circular buffering operation for the two or more warning messages through the message queue buffer, when message renewal times for the two or more warning messages expire.
