CASE 04 Motorised Turn Table Solution Replacing an unreliable pneumatic 0°–90° turntable with a motorised, clutch-protected index. The Challenge Pneumatically operated 0°–90° turntables are prone to pressure drops, mechanical binding and contamination. Common failure modes: stalling mid-rotation, air leaks, jerky or uneven movement. Failure to stop precisely at the 90° mark — every miss is a misaligned part downstream. The PAIR Solution A motorised turntable with a clutch mechanism that eliminates erratic, pressure-dependent movement. Consistent, repeatable stop at the index point — protecting parts and operators from clutch-absorbed overrun. 0° → 90° Repeatable, clutch-protected indexing — no more pressure-dependent stalls or overshoot. https://drive.google.com/file/d/13Y8QNKTWAqzjPSpOXBgyJV-3lk7j8w2J/view#t=1

CASE 03 Assembly Line Conveyor Systems Replacing stick-slip roller motion with a positive-drive bevel gear power-and-free conveyor. The Challenge Chain elongation over time, throwing pitch and timing out across the line. Stick-slip, jerky movement on the line. Accelerated fatigue failure in the drive train. Excess noise and vibration during transfer. The PAIR Solution Bevel gear power-and-free roller conveyor, delivering smooth, positive-drive motion with the flexibility to accumulate or release pallets on demand. ↓ NVH Lower noise, vibration and drive-train fatigue versus standard roller conveyors. https://drive.google.com/file/d/107uODal3Q74JIuMbxMIAHRVhmAKy5iH8/view?usp=sharing#t=1

CASE 02 Pinion Preload Monitoring for Drive Heads Collapsible-washer preload setting, taken from operator feel to continuous, monitored control. The Challenge Crush torque spikes sharply near the end point — overshoot the spec and bearings are overloaded, leading to premature failure. Sleeves resist crushing early on, tempting operators toward power impact wrenches that blow straight past the ideal setting. Manual torque wrenches give bouncing, erratic readings — a precise, repeatable stop point is nearly impossible to hit by feel. The PAIR Solution Continuous, real-time monitoring of preload torque as the sleeve is crushed — stopping at exactly the specified point, every time. 95% First-Time Quality on a step that used to depend entirely on operator feel. https://drive.google.com/file/d/1_Edo32ByXcCWroorZWPPNRNfYBOYUqDH/view?usp=sharing#t=1

CASE 01 Automated Shim Selection Machine Valve-clearance shim selection, re-engineered from a two-pass torque-and-recheck cycle into a single-pass machine decision. The Challenge Fully manual cycle: assemble a trial shim, torque all 8 cam-cover bolts, gauge every valve for clearance, unscrew, recalculate, reassemble the final shim. Every cover was torqued and de-torqued twice per engine — burning cycle time and risking inconsistent bolt torque on rework. The PAIR Solution Part is assembled once with master shims — no cam-cover bolts needed at this stage — then loaded onto the Shim Selection Machine. The machine cycles automatically and calculates the exact shim required; the master shim is swapped for the correct one and the cover is torqued a single time. 2× → 1× Torque cycles eliminated per unit — no more assemble‑measure‑disassemble‑reassemble loop. https://www.youtube.com/watch?v=XHOmBV4js_E
