Curved Traffic Display Break Detection With User Prompting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic devices with electronic displays face risks of breakage due to stress, leading to reduced display operation and driving safety, with no effective detection methods to mitigate these issues.
Innovation Solution
A risk control system comprising a light emitting device, processing element, and user prompting element, which detects and alerts users to potential breaks in the display device through a prompt signal system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device is bent to match the shape of the instrument panel or center console, then the display device can fit the traffic device shape, but the display device bears great stress and risks break in long-term use
Solution Approach 1:
The patent applies preliminary action by incorporating a detection mechanism that monitors the display device before actual breakage occurs. The system detects potential breaks in the light emitting device or substrate through electrical connection changes, allowing early warning and preventive maintenance before the display fails completely, thus resolving the contradiction between adapting the display to bent shapes and maintaining its reliability.
2Device complexity
If no detection method is provided, then the device structure remains simple, but users are only aware of breakage when the chip breaks and display device cannot be used, reducing driving safety
Solution Approach 1:
The patent implements feedback by creating a closed-loop detection system. The detection mechanism continuously monitors the electrical connection status of the light emitting device and substrate, provides real-time feedback about potential breaks to the user, and enables timely intervention. This feedback mechanism significantly improves driving safety by alerting users before complete display failure occurs, while adding only minimal system complexity.
3Reliability
If the light emitting device or substrate breaks, then the display operation is affected, but there is no effective detection method to alert users in advance
Solution Approach 1:
The patent uses an intermediary approach by introducing a detection mechanism that acts as a mediator between the light emitting device/substrate and the user. This intermediary system detects electrical connection changes caused by potential breaks and translates them into user-alertable signals, making the invisible breakage process detectable and actionable before it affects display operation.

AI summary
A risk control system for traffic devices includes a light emitting device, a processing element and a user prompting element. The processing element is electrically connected with the light emitting device, and outputs a prompt signal. The user prompting element is electrically connected with the processing element, and receives the prompt signal.
