Challenge details:
The gear and shaft manufacturing process involves several stages of machining operations for producing the required gear profiles and various other features on the gear and shaft. These features and profiles are critical to quality (CTQ) and need to meet design tolerances (ref. Figure 1). The current inspection setup is a manual process involving multiple measurement equipment that are time-consuming and result in audit-based sampling rather than 100% inspection. This limits our ability to ensure full compliance with CTQ parameters and traceability across production batches.
Gear Critical to Quality (CTQ) dimensions inspection:
- Inside diameter (ID/Bore diameter)
- Linear dimensions
- Face runouts
- Special profile on Gear teeth
Shafts Critical to Quality (CTQ) dimensions inspection:
- Outer diameter
- Linear dimensions
- Linear dimension with groove position
- Face and OD runouts
- Special profile on Gear teeth
We are seeking an innovative, automated inspection solution that can:
- Perform comprehensive inspection of gears and shafts with measurement accuracy as per design tolerance in drawing (minimum tolerance band value is 0.012mm or +/-0.006mm).
- Cover maximum CTQ parameters with minimal cycle time (Production volume 100% inspection @1300 Gears & @450 Shaft per day).
- Ensure 100% inspection with digital traceability of measurement results (QR code scanning)
- Generation of tabular and graphical reports for selected batch with SPC calculations
- Provision to connect data directly to QDAS server
- Be scalable and adaptable to different gear/shaft variants (Shaft length from 100 to 550 mm; Gear diameter from 50mm to 300mm)
- Cost effective
Digital Traceability for Individual Solar Cells Across the Manufacturing Lifecycle
Rewards proportional to the value add! Few solutions could be available! Efforts might be needed to customize the solution.
We are looking for a non‑invasive, robust solution to uniquely identify each solar cell throughout manufacturing and maintain its identity from full cell to final module.
Sustainable Packaging Solution for Edible Salt Transport
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are looking for an innovative, sustainable, and food‑safe packaging solution to replace the current 50‑kg bags used for edible salt.
Automated removal of crown wheel from furnace for quenching
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
Crown wheels, which are critical components in automotive axles, are heated in a furnace to temperatures exceeding 960-degree C. The crown wheels are stacked together - typically 5 or 6 crown wheels - and each crown wheel is separated by a spacer (fixture). There are 25 types of crown wheels across 5 distinct families, each requiring precise thermal treatment.The crown wheels can weigh up to 45 Kg and have a diameter of 200-400 mm.The crown wheels need to be picked from the furnace and placed on the quenching fixture, before which the spacer needs to be removed. The takt time for one crown wheel is 1 minute.
Zero waste discharge solution for chemical sludge and ATFD salts from electronics manufacturing
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are seeking practical, scalable, and economically viable solutions that can eliminate/reduce the sludge waste and ATFD salt volumes generated through the ETP and ZLD facilities and identify potential value creation through resource recovery pathways. The treatment process should be capable of seamless integration with the current operations.
Separation of Zn and Fe from GCP sludge cake
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We seek technologies capable of recovering zinc from blast furnace gas cleaning plant sludge so that it can be safely and effectively reintroduced into the pellet‑making process. Any solution must be compatible with the sludge's typical composition—more than 20% carbon, 6-10% iron, and measurable quantities of manganese, calcium, and other heavy metals—while reducing its hazardous characteristics. Technology providers are expected to deliver end‑to‑end solutions, including feed preparation, zinc recovery processes, and downstream offtake arrangements. Proposed approaches should ensure long‑term operational feasibility and support the company's broader circular‑materials strategy.
Cobot for fuel tank fitment in a vehicle assembly line
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
A solution is desired to automate this activity which involves picking up the fuel tanks from the trolley, properly orient and place them on the brackets on the vehicle chassis and fasten the clamps to secure the tanks in place. The device used should be safe to operate alongside humans working on the assembly line (cobot).
