Vehicle Welcome Light Display Switching via Power Sequence Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing welcome light systems in vehicles require manual replacement of icons, making it inconvenient to update or change the displayed content, which limits user flexibility and safety enhancements.
Innovation Solution
A display system comprising a center console, processing device, and display device that generates and decodes a power sequence with a specific waveform characteristic, allowing users to conveniently switch and update the display content through a central control computer, using a data table and lookup table to determine the display image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual replacement of icons is performed in the welcome light, then the display content can be changed, but the operation convenience deteriorates and time is lost
Solution Approach 1:
The patent replaces the manual mechanical replacement process with an electronic control system. The center console sends power sequences through wiring to the display device, which automatically changes the welcome light content without requiring physical disassembly or manual intervention. This substitutes mechanical operations with electrical signaling and automated control.
Solution Approach 2:
The system enables self-service operation where the welcome light content can be changed through the vehicle's existing central control console. The user interacts with the familiar infotainment system rather than needing specialized tools or procedures, making the system serve itself through existing infrastructure.
2Adaptability or versatility
If manual replacement of icons is performed in the welcome light, then the display content can be changed, but the time consumption increases
Solution Approach 1:
The patent replaces the manual mechanical replacement process with an electronic control system. The center console sends power sequences through wiring to the display device, which automatically changes the welcome light content without requiring physical disassembly or manual intervention. This substitutes mechanical operations with electrical signaling and automated control.
Solution Approach 2:
The system stores multiple welcome light content options in advance within the display device or center console. When a change is desired, the pre-prepared content can be immediately activated through the power sequence without requiring time for preparation, assembly, or configuration of new icons.
3Ease of manufacture
If fixed icons are used in the welcome light, then the manufacturing process is simple, but the adaptability deteriorates
Solution Approach 1:
The patent separates the welcome light system into distinct functional modules: a fixed display device structure and a programmable control system. The display device itself can remain relatively simple in manufacturing, while the adaptability is achieved through the separate center console control system that sends different power sequences to change content, allowing simple manufacturing with enhanced flexibility.
Solution Approach 2:
The display device is designed to be universal and can display multiple different welcome light contents through a single unit. Rather than manufacturing different physical icons for different functions, the same display device can be programmed through the center console to show various content, making the manufacturing process simpler while maintaining high adaptability.
Data Source
AI summary
A display system suitable for a vehicle is provided. The display system suitable for the vehicle includes a center console, a processing device, and a display device. The center console is configured to generate a power sequence according to a customization setting, and the power sequence corresponds to content of a data table. The processing device is configured to receive the power sequence and decodes the power sequence through a lookup table to generate a decoding result. The lookup table includes the content of the data table. The display device is coupled to the processing device and is configured to display a display image according to the decoding result.
