ROI Calculation Logic

Assuming a 20% improvement in defect detection accuracy on industrial inspection lines. With a monthly production of 100,000 units, a 3% defect rate, and a defect cost of $33.33/unit (AI est.), annual defect costs are $1.2M (AI est.). Improving the defect rate to 2.4% would reduce annual defect costs to $0.95M (AI est.), yielding an annual cost reduction of $0.25M (AI est.). Additionally, efficiency gains from reduced inspection time and re-inspection due to fewer false positives are estimated at $0.75M annually (AI est.), totaling an estimated $1M in annual economic impact.

Speed to Market
4× faster than in-house development
This technology significantly shortens the initial development phase as its fundamental image sensor components and control algorithms are already established and patented. The clear design principles of the segmented photoelectric conversion elements and readout circuit operation could reduce the time for principle verification and basic design by approximately 3 years compared to development from scratch. This allows adopting companies to accelerate time-to-market and establish a competitive advantage sooner.
