Abstract
In this paper, we show that aligning the hinges in a flexure-based rhombus-shaped piezo-driven amplifying mechanism increases its performance. A simplified analytical model is first proposed based on the definition of the input and the output stiffnesses of an amplifying mechanism. Approximate analytical expressions for both stiffnesses are then derived for two hinge configurations: parallel and aligned. The model predicts increases in the free stroke, the blocking force and the efficiency which are confirmed by numerical simulations. Most importantly, a reduction of the bending in the hinges is confirmed both numerically and analytically. As a matter of fact, simulations show a significant decrease (40%) of the maximal stress when the hinges are aligned.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
