Car Collision Damage Mapping for Precise Repair Estimates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for estimating collision damage to cars are limited in defining damage to individual parts beyond pre-defined shapes, sizes, and forms, and do not accurately account for the severity and impact of damage on repair time and cost.
Innovation Solution
A computer system and method that allows users to define collision damage on car body parts through freehand drawing or image processing, considering impact levels, part characteristics, and interdependencies, to generate accurate repair estimates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pre-defined shapes, sizes, and forms of dents are used for damage assessment, then the assessment process is simplified and standardized, but the accuracy and flexibility of damage estimation is reduced
Solution Approach 1:
The system segments the car body into multiple body parts (hood, doors, fenders, bumpers, etc.), and further segments each body part into multiple areas. This hierarchical segmentation allows the system to maintain simplicity through standardized structures while achieving precision through granular damage area definition. Users can define damaged areas within specific body parts, combining the benefits of both simplification and accuracy.
Solution Approach 2:
The system applies local quality by allowing different damage characteristics to be defined for different areas of the car body. Each damaged area can have unique properties (shape, size, form, severity) independent of other areas. This enables precise local damage assessment while maintaining overall system organization through the segmented structure.
2Measurement precision
If detailed damage definition is enabled for individual body parts, then the accuracy of repair cost and time estimation is improved, but the complexity of the assessment system increases
Solution Approach 1:
The system reduces complexity through segmentation by organizing the assessment into hierarchical levels: car body → body parts → areas within body parts. This segmentation allows the complex task of overall damage assessment to be broken down into manageable, standardized steps. Each level has its own set of predefined options, making the system easier to navigate despite the detailed assessment capability.
Solution Approach 2:
The system applies universality by using a standardized assessment framework that works across all body parts and damage types. The same general process (select body part → select area → define damage characteristics) applies universally, reducing the need for separate complex procedures for different scenarios. This multi-functional approach simplifies the overall system while maintaining detailed assessment capabilities.
3Measurement precision
If freehand drawing and image processing methods are implemented, then the flexibility and precision of damage area definition is improved, but the ease of operation is reduced
Solution Approach 1:
The system applies preliminary action by providing predefined body parts and areas that users can select before defining specific damage characteristics. This preliminary selection step prepares the framework, allowing users to then focus only on defining the specific damage within that framework. The image processing and freehand drawing tools are prepared and ready, reducing the overall operational complexity.
Solution Approach 2:
The system uses the computer interface as an intermediary between the user and the complex damage definition processes. The interface provides drawing tools, image processing capabilities, and predefined options that mediate between simple user actions and complex damage assessment requirements. This intermediary layer simplifies operation while maintaining precision through the tools it provides.

AI summary
For determining an estimate of the collision damage to a car, a body part (3) of the car is displayed in a user interface (100). Through the user interface (100), input is received from the user for drawing on the body part (3) one or more damaged areas (4c, 5c). Specifically, the damaged areas (4c, 5c) are defined in each case by an outline of the damaged areas (4c, 5c), drawn on the body part (3) by way of a drawing tool (108, 108') or as detected from an image. Subsequently, an estimate of the repair cost (C) and the repair time (T) is generated for the user, based on the damaged area (4c, 5c) drawn on the body part (3). Enabling the user to define the outlines of damaged areas (4c, 5c) makes it possible to define and estimate efficiently, flexibly, and accurately collision damage to a car.
