AI Technical Summary

Technical Problem

Existing wire harness testing methods are costly, prone to human error, and lack reliability in ensuring signal integrity, leading to environmental waste and increased manufacturing costs due to the rejection of faulty harnesses, while recycling is hindered by the perceived unreliability of reused components.

Method used

An automated wire harness diagnosis system that includes a harness interface, load characterisation, and wire management subsystems, utilizing DC and AC stimuli, precision resistance measurement, and machine learning to assess wear, tear, and insulation degradation, ensuring reliable recycling and remanufacturing.

Benefits of technology

Ensures the reliability of recycled wire harnesses by accurately diagnosing faults and estimating residual lifetime, reducing waste and environmental impact, and promoting a circular economy by extending the operational lifespan of harnesses.

Abstract

The present disclosure provides for an automated wire harness diagnosis system and process for measuring the electrical characteristics of a wire harness in order to provide an estimate of the useful lifespan of the wire harness. Embodiments described herein may be deployed in a remanufacturing environment or in a manufacturing environment to provide statistically based estimates of the remaining useable lifetime of the wire harness, thus allowing to reduce costs and waste when producing wire harnesses within a circular economy environment.
