Chain Stretch Detection via Adjacent Roller Height Differences

The patent divides the chain into multiple measurement sections, each with its own measurement point. Instead of attempting to measure the entire chain at once, the system segments the measurement task into discrete sections, allowing for more precise local measurements while maintaining comprehensive coverage through multiple segments.

The patent applies different measurement strategies to different sections of the chain based on local characteristics. Each measurement point is positioned and configured according to the specific meshing conditions at that location, accounting for variations in meshing heights and structural complexities that differ across the chain length.

The patent segments the chain into multiple measurement sections with individual measurement points. This allows the system to capture local variations in meshing height changes that occur during chain stretch, rather than assuming uniform increase across the entire chain. Each segment's measurement reflects the actual local deformation characteristics.

The patent transitions from assuming one-dimensional uniform meshing height increase to measuring three-dimensional variations in meshing heights at multiple discrete points along the chain. This dimensional expansion allows capture of the complex spatial distribution of stretch effects that cannot be represented by a single uniform parameter.
