Sl. No. | Client Objective|

1	To reduce the time required for shoe polishing
2	To reduce the physical effort and manual work involved in polishing shoes
3	To provide a semi-automatic shoe polishing process
4	To polish formal, casual, leather, and synthetic shoes
5	To provide effective cleaning and polishing of the shoe surface

Design and develop a low-cost Semi-Automatic Shoe Polishing Machine within a target budget suitable for household and small-scale use. The machine should clean, apply polishing liquid, and buff formal, casual, leather, and synthetic shoes using motor-driven rotating brushes. It should detect the presence of the shoe using an IR sensor, provide controlled polishing-liquid application, and allow the operator to control the system through a pedal/manual control.

Sl.No	Constraints
1	Must function as an automated tabletop device with manual loading
2	Overall weight must remain below 7.5 kg
3	Frame dimensions must not exceed 450 mm (L) × 300 mm (W) × 250 mm (H)
4	Polishing cycle must complete within 45 to 90 seconds per pair
5	Production budget capped strictly at ₹3,500
6	Power pull limited to 40–80 W on 110–230 V AC or a 12 V DC power source
7	Flexibly fits standard footwear sizes from UK 5 to UK 12
8	Complete construction and validation within a 12-week timeframe
9	Built with acrylic/PVC panels and fitted with automatic safety cutoff switches

The objective is to manufacture a lightweight, semi-automated shoe cleaning system that yields a brilliant gloss with zero user effort. The final design must be safe, long-lasting, and simple enough for daily home or office use without complex controls.When footwear is inserted, an ultrasonic sensor triggers the cycle. A DC gear motor powers the brush assembly, starting with an 8-to-12-second dry scrub to remove surface grit.

Sl.No	Functions
1	Detect footwear placement using an ultrasonic distance sensor
2	Convert electric power into high-torque rotation via timing belts and gear motors
3	Strip off caked dirt using stiff bristle wheels for 8 to 12 seconds
4	Dispense liquid polish accurately using a regulated mini peristaltic pump
5	Distribute wax evenly across curved leather using oscillating side brushes
6	Buff the shoe surface using dual microfiber wheels spinning at high RPM

The objective is to design and build an automated shoe polisher that cleans, waxes, and buffs footwear effortlessly in seconds. Built for ultimate convenience, the unit operates on a plug-and-play basis, requiring no adjustments or special skills while delivering consistent, high-gloss results every time.

Once the ultrasonic sensor detects a shoe inside the housing, the drive motor engages the shaft assemblies. The machine first scrubs off dry dirt using stiff bristle wheels for 8 to 12 seconds, drips a measured dose of liquid polish onto the shoe, spreads it uniformly using oscillating side brushes, and finishes with high-speed microfiber buffing wheels to create a streak-free shine.

The whole sequence finishes within 45 to 90 seconds per pair. Built within a ₹3,500 budget over a 12-week project timeline, the complete unit weighs under 7.5 kg and fits within a compact 450 mm × 300 mm × 250 mm footprint, accepting shoe sizes from UK 5 to UK 12. Powered by 110–230 V AC or a 12 V DC supply (40–80 W)
