Introduction

NorrSpect AB, a Swedish AI company headquartered in Umeå, is a pioneer in developing cutting-edge, AI-powered inspection systems tailored for the manufacturing sector. With successful deployments across Europe, including collaborations with Volvo Cars and other leading OEMs, NorrSpect’s flagship product, NorrStudio, brings a new standard to visual quality inspection—automated, scalable, and intelligent.

This case study highlights how NorrStudio helps automotive and EV manufacturers automate post-deployment and maintenance inspections for mission-critical components.

Industry Challenge

As vehicles become more complex—particularly in EVs—the demand for predictive maintenance and automated visual checks is growing. Manual inspections are often time-consuming, prone to inconsistency, and costly to scale.

To maintain performance and ensure safety post-deployment, manufacturers need an AI-based inspection tool that can:

• Detect hidden defects

• Maintain uniform inspection standards

• Work with diverse lighting and environmental conditions

• Integrate with existing maintenance workflows

The NorrStudio Solution

NorrStudio is an AI inspection software platform that uses advanced computer vision and machine learning algorithms to detect, classify, and quantify defects in real-time. Integrated into maintenance bays or portable inspection kiosks, the system is hardware-agnostic and can be used with fixed or mobile cameras.

The system is trained on client-specific datasets and works in both inline and offline inspection environments.

Key Use Cases for Maintenance / Post-Deployment Checks

1. Corrosion Detection on Underbody

• Problem: Salt, moisture, and time degrade vehicle underbodies, particularly in northern climates.

• Solution: NorrStudio’s corrosion model identifies rust patches, pitting, and coating wear with pixel-level accuracy, flagging early signs before structural damage occurs.

2. Fuel Line Clamp Inspection

• Problem: Loose or misaligned clamps can lead to hazardous fuel leaks.

• Solution: Trained models detect clamp placement and alignment errors, verifying correct positioning using pre-set reference standards.

3. Crack Detection in Suspension Components

• Problem: Micro-cracks in struts, control arms, or knuckles can lead to catastrophic failures.

• Solution: NorrStudio’s crack detection module uses high-resolution imaging and deep learning to detect surface and edge-line fractures invisible to the human eye.

4. Tire Wear Pattern Recognition

• Problem: Uneven wear patterns signal alignment issues, suspension problems, or improper inflation.

• Solution: The system segments tire tread zones and quantifies wear depth across the surface, generating wear maps and classifying anomalies (e.g., camber wear, cupping).

5. Windshield Chip and Crack Analysis

• Problem: Small chips can expand into large cracks, requiring costly replacements.

• Solution: NorrStudio detects minor cracks, edge-line damage, and starburst chips—even on tinted or reflective glass—and logs the location and size for service teams.

6. Cooling System Leakage

• Problem: Coolant leaks in EVs or ICE vehicles can lead to battery degradation or engine overheating.

• Solution: The software inspects hoses, reservoirs, and fittings for fluid residue, discoloration, and surface pooling using multispectral image cues.

System Capabilities

• Defect Parameterization: Location, size, severity, shape classification

• Integration: API-ready for MES/ERP systems

• Deployment Modes:

  • Fixed station with overhead cameras

  • Mobile tablet-based inspections

  • Retrofit to existing service lanes

• Reporting: Auto-generated reports for Quality Control Records (QCR) and New Part Alerts (NPA)

Client Impact

By deploying NorrStudio in post-deployment maintenance workflows, our clients have achieved:

• Up to 80% reduction in manual inspection time

• Consistent defect detection accuracy above 95%

• Real-time service alerts, minimizing recall risk

• Early failure pattern discovery, feeding back into design improvements

Conclusion

NorrStudio redefines what’s possible in post-sale quality assurance for automotive and EV manufacturers. Whether it's underbody rust or invisible cracks, NorrStudio ensures nothing goes unnoticed. As vehicles evolve, so must inspection—NorrSpect is proud to lead that evolution.
