Reducing clean water wastage in homes. Overall (Singapore) clean water wastage due to excess/non-controlled water outputs (taps, showers, etc..) in the home.

Water is a valuable and costly resource – even more so in Singapore. Homeowners are aware of the need to save water both for the environment and utility cost, but so far current water saving solutions do not provide the same level of experience. Consumers are unwilling to sacrifice the familiar water pressure and water flow output that they are used to for showering or washing dishes etc.

The challenge is to provide new water savings solutions for use in households. It can either be a new water saving system, device or an add-on. The target is to reduce the normal water output by 70%, while maintaining good pressure and water flow output. For add-ons, the cost of the device must be below $7 SGD to be effectively marketed and adopted by the mass end consumers. New systems or devices can be priced in a similar range to existing systems or devices.

For this challenge:

  • You must clearly define the target water outlet in the home
  • Preferably, the solution is able to provide for all general water uses, but it is also acceptable to provide a solution for a specific use of water (i.e. only showering, only cleaning dishes…etc)
  • Need to first satisfy the end consumer with good water pressure and good water flow output, to have a chance for them to switch. Once satisfied, then the cost angle can be considered.



Wheelchair users in Singapore today are plagued with mobility issues that are not faced by the common population. An estimated 170,000 flats in Singapore have multiple steps at the entrance of the house, and this poses a great challenge to wheelchair users. In addition, it may not always be possible to install ramps to all these homes. As a result, wheelchair users in these circumstances tend to stay at home. As the population continues to age, the number of wheelchair users in Singapore is expected to rise. Hence, to build a more inclusive community, more needs to be done to address issues faced wheelchair users, to enable them to be more independent and integrate better with the society.

Innosparks is interested in improving the mobility of wheelchair users by building a device that enables them to overcome the small flight of steps outside their houses. This device should be safe and straightforward to use, and can be operated by a caretaker. The device should also not be physically demanding to operate. The device should require minimal maintenance and would be preferred to be mechanically operated. It can be assumed that the device can be stored outside the house.

For this challenge

  • The maximum height of steps to overcome is 50cm; the maximum depth of the steps is 80cm; the width of the door is 83cm
  • It only allows the usage of manual wheelchairs and support a total weight of 150kg
  • Minimal to no renovation should be done to the users’ house
  • Cost of the device is targeted below S$500.

Reducing everyday, single-use plastics

Plastic items, and especially one-time use plastics items such as straws, utensils, plates and bags are hazardous to the environment as they are non- biodegradable. Plastics often end up in the oceans and on landfills creating environmental and healthy issues, as well as harm to animals.

Global consciousness of the aggravated environmental problem sees new initiatives being spawned to reduce, re-use and recycle plastic. InnoVenture wants to do our part for the environment and we thereby challenge students to develop non-plastic alternatives for single-use plastics. Apart from the engineering, the teams must also consider general acceptance of the product (i.e. business model).

For this challenge

  • Replacement of any single-use plastic can be considered

In order to expedite resuscitation and improve its efficacy, resuscitation drugs and equipment have to be readily available. To facilitate this, the list and layout of the resuscitation drugs and equipment in the resuscitation trolley (E-trolley) have been standardized in all SAF Medical Centres. All drawers of the E-trolley are sealed at all times with a serialized cable tie, in addition to the physical lock. Regular checks of the resuscitation drugs and equipment are carried by the Duty Medic in the medical centres. After a resuscitation case, the E-trolley will be re-stocked to full quantity as soon as possible.

During unscheduled audit checks, E-trolleys across medical centres are found with items that may be expired / incorrect / not available / or in the incorrect drawers. SAF Medical Centres are looking for a method to help with stocktaking of the drawers. The person doing the stocktaking should:

  • Be able to see if all items that are supposed to be in the trolley, are in the trolley;
  • Be able to see if all items are in the right place in the trolley;
  • Able to track the expiration date and alert if the expiration date has passed of the specific item

For this challenge

  • Existing E-trolley dimensions:
    • Drawer 1: 58.5cm X 49.1cm X 10.5cm (External), 57cm X 49.1cm X 9.5cm (Internal)
    • Drawer 2: 58.5cm X 49.1cm X 8.0cm (External), 57cm X 49.1cm X 6.8cm (Internal)
  • Trolleys are checked ≥ 01 time per week and after each resuscitation case.
  • There are 2 types of drawers (example pictures can be found on the website) – you may choose either drawer or attempt to provide a solution for both
    • You may change the layout of the trays and positioning of the items if necessary
  • Solutions can be either complete redesigns of the trolleys OR external and/or internal scanning technologies keeping the trolley intact OR a combination of both.
  • The solution can be automated or manual – If manual, then the stocktaking should be able to be done in under 3 minutes.

Continuous Condition Monitoring of Cranes

Cranes are used extensively in construction and port operations. At present, cranes are equipped with several fail-safe mechanisms that prevent unsafe operation. However, these measures are not fail-proof. A different approach to this can be in the continuous monitoring of the condition of the crane. A good first step will be to measure the strain that the equipment is subject to daily. This will provide an indication to the impact of daily operations on the health of the crane.

Surbana Technologies is interested to develop a strain monitoring solution that is easy to retrofit on existing cranes. The focus of the solution will be to provide accurate strain measuring of different components in the crane. Ideally, the solution will provide wireless communications for real-time/on-demand monitoring.

Teams can start with the hinges, as these are the components subjected to the greatest stresses; however, teams are open to look into any other areas as well.

For this challenge

  • The teams may develop the solution for any crane type (construction or port), but the team will have to customize the solution for the selected crane type
  • The hardware solution should be industrial grade, e., able to withstand external environments
  • The total cost of the solution should be capped at $5,000 per crane, where reasonable
  • The teams are welcome to develop a data science solution to calibrate and detect the condition of the cranes, based on the strain measurements
