The claimed invention is the system architecture that performs mutual cross-verification between observed and expected position/pressure changes to identify faults; the particular method used to derive the expected values (model-based, empirical, or otherwise) is an implementation choice left to the skilled artisan and is not part of the claimed subject matter.

It spells out the sensors, the time-window comparison, and the basic mismatch logic in straightforward terms. That is the extent of what is new here.\n\nThe description stops at the procedural outline. There are no formulas for computing the expected values, no example thresholds, and no discussion of how factors like load, temperature, or soil resistance would be handled. The document also contains no test results or validation steps.\n\nBecause this is a patent filing rather than a research paper, it does not present evidence that the approach holds up in practice. The core assumption—that the two signals alone are enough to generate reliable expectations—remains unexamined.\n\nEngineers working on patent portfolios in agricultural machinery might note the claims for prior-art purposes. Technical readers looking for methods, data, or reproducible logic will find nothing to engage with.
