Mobile Terminal Image Guidance for Vehicle Damage Proof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of sharing economy platforms, there is a challenge in efficiently documenting and proving damage to high-value products like vehicles and audio equipment, which are borrowed by multiple users, making it difficult to determine who caused the damage and when.
Innovation Solution
A mobile terminal equipped with a camera, touch screen, and wireless communication unit is used to generate proof data for damage on products registered in a server. The terminal guides the user to capture specific portions of the product using guide information based on vehicle information, and detects new damage by comparing images, allowing for easy documentation and communication of damage findings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual damage documentation is used for shared products, then users can record damage, but it is difficult to prove who caused the damage and when, leading to loss of information reliability
Solution Approach 1:
The system captures images of the product condition before and after use, and automatically records timestamps and user identification information. This preliminary documentation creates reliable proof data that attributes damage to specific users and time periods, eliminating the need for manual damage reporting and ensuring accurate damage attribution.
2Measurement precision
If comprehensive product inspection is performed to detect all damage, then damage detection accuracy improves, but the time and complexity of the inspection process increases
Solution Approach 1:
The system automatically captures reference images of the product condition at the beginning and end of each rental period. These pre-captured images serve as the basis for automatic damage detection, eliminating the need for manual inspection while maintaining high detection accuracy through image comparison algorithms.
Solution Approach 2:
The manual inspection process is replaced by an automated image-based detection system. The controller compares images captured at different time points to automatically identify damage, substituting human inspection with computational image analysis, thereby reducing inspection time while maintaining or improving detection accuracy.
3Loss of information
If users are guided to capture specific portions of the product, then the completeness of damage proof data improves, but the complexity of the capture process increases
Solution Approach 1:
The system provides real-time feedback to users through the touch screen, displaying guide information that indicates which portions of the product should be captured and whether the captured images meet the required standards. This feedback mechanism ensures complete damage proof data collection while simplifying the user interface and making the capture process more intuitive.
4Reliability
If multiple images are captured to ensure complete damage documentation, then the quality of proof data improves, but the time required for data collection increases
Solution Approach 1:
The system automatically captures multiple images of the product at predetermined time points (beginning and end of rental) without requiring users to manually take multiple photos. The controller manages the image capture sequence and ensures all necessary views are obtained, thereby maintaining high proof data quality while improving collection efficiency through automation.
