Abstract: The thickness of the “orbiting scroll” flange,a core component of scroll compressors,has a critical impact on compressor performance and reliability. To address the issues of large measurement errors and high risk of manual data input errors in the existing measurement system on the production line,an innovative design scheme for the orbiting scroll flange thickness measurement system was constructed based on the TRIZ （Theory of Inventive Problem Solving） theory,integrating multiple methods such as the idealization method,conflict resolution theory,and nine-screen method. Verification through repeatability and reproducibility analysis shows that the repeatability and reproducibility （R&R value） of the new system reaches 7. Trial production verification indicates that zero data input errors are achieved within one year,and the production line scrap rate is reduced by 10.5%,effectively solving the technical problems in production.
