Challenge details:
Drive pinions and crown wheels for each automotive axle are manufactured as a pair and machined to achieve optimal and unique tooth form adjusted at the factory to work together, ensuring a precise fit and contact pattern, depth, width and spacing for that specific fit. It is thus necessary that each pair of crown wheel and pinion gears are marked so that the correct pair is assembled by the operator. To enable the operator to pick the correct pairing, currently, the ‘crown wheel and pinion wheel (pair)" are marked with the same code. and is done using acid marking. This marking however, gets smudged or erased or hidden which makes it difficult to identify the exact pairing. The parts are made of alloy steels and weighs approx. 7-19 kgs.
We are thus seeking cost-effective and reliable solutions that can correct pairing of the two parts, the crown wheel and drive pinion. It should be scalable across all part variants and seamlessly integrate into the existing production workflow (400 assemblies/day).
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.
Non-Invasive Identification and Verification of Underground Cable Joints Prior to Excavation
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are seeking a non‑invasive, above‑ground solution to identify underground cable joints and accurately distinguish the correct live cable among closely spaced cables, without excavation or offline signal injection, to support safe and efficient excavation planning.
Real Time Monitoring of Electrical Systems in Low- or No- Connectivity Remote Locations
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are seeking a solution for reliable monitoring of electrical systems and field operations in low or no network environments, enabling secure offline operation, safety‑critical workflows, and seamless data synchronization once connectivity is available.
Automatic inspection system for gears and shafts for CTQ parameters compliance
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
We are seeking solutions for automated measurement of critical to quality parameters in gear shafts for 100% of parts manufactured.
Eliminating LPG flame curtains in Annealing furnaces
Rewards proportional to your differentiated solution! More than one solution is expected to exist. Solution may be implemented without customization.
Gold jewellery annealing is performed in a furnace with a 75% hydrogen and 25% nitrogen atmosphere, where LPG flame curtains are used at the entry to prevent oxygen ingress during loading and unloading. There is a need to eliminate the use of flame curtains without compromising product quality, process stability, or safety. The solution must prevent oxidation, integrate with the existing setup, and enable safe, continuous operation within current spatial and retrofit constraints.
