What’s the Ideal Spring Torque Curve for Cordless Shades? A Practical OEM Tuning Framework
What’s the Ideal Spring Torque Curve for Cordless Shades? A Practical OEM Tuning Framework An engineering tuning framework that turns “hand-feel” into measurable targets—then locks it into spring selection, pre-tension, braking, and production tolerances. Quick Summary The engineering definition of an ideal torque curve is simple: across the full travel z, keep the net drive […]
