Solution Overview
Problem
Manual inspection of vehicle condition at checkpoints is time-consuming, costly, and prone to inaccuracies, especially when determining the age or maintenance needs of vehicles, which can lead to delays and inefficiencies in vehicle management.
Innovation Solution
An electrochromic coating system on vehicles that changes appearance based on determined vehicle attributes and location, using neural networks and AI to assess the condition and provide visual indicators of wear or maintenance needs, allowing for automated and accurate assessment by inspectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection of vehicle condition is performed at checkpoints, then detailed assessment of vehicle age and maintenance needs can be conducted, but the inspection process becomes time-consuming and costly
Solution Approach 1:
The system performs preliminary assessment of vehicle condition by analyzing vehicle information (age, mileage, maintenance history) before the vehicle reaches the checkpoint. The electrochromic coating is pre-programmed with weightage factors for different vehicle attributes, so that when the vehicle enters the boundary area of the testing zone, the coating automatically displays the assessed condition without requiring time-consuming manual inspection at the checkpoint.
Solution Approach 2:
The system creates a visual copy or representation of the vehicle's internal condition data through the electrochromic coating display. Instead of manually examining the actual vehicle components, inspectors can quickly assess the vehicle condition by observing the information displayed on the coating, which replicates the essential maintenance status and age indicators.
2Reliability
If manual inspection methods are used to determine vehicle maintenance needs, then comprehensive evaluation can be performed, but the process becomes costly and prone to inaccuracies
Solution Approach 1:
The vehicle's electrochromic coating system performs the assessment function automatically using pre-stored vehicle information and weightage factors. The coating itself serves as the display medium that presents the maintenance status without requiring external inspection equipment or complex manual evaluation procedures, thereby improving reliability while reducing system complexity.
3Productivity
If electrochromic coating changes appearance based on vehicle attributes, then rapid visual assessment is enabled, but the system requires complex electronic circuitry and control mechanisms
Solution Approach 1:
The system merges the vehicle's existing electronic control units (for navigation, sensor data collection, and vehicle management) with the electrochromic coating control function. By integrating these functions into existing automotive electronics rather than adding separate dedicated systems, the patent achieves rapid visual assessment capability while minimizing the increase in overall system complexity.

AI summary
A computer-implemented method for altering an appearance of an electrochromic coating of a vehicle is provided. The method includes determining that a vehicle is a boundary area of a testing zone based on a determined location of the vehicle. The method also includes changing a base appearance of the electrochromic coating of the vehicle to an altered appearance based on the determination that the vehicle is in the boundary area.
