We are looking to create an innovative design which will incorporate a scoop into a screw on cap for powder product. The cap is a 97mm triple lead cap and the scoop is a 26.5cc scoop with a folding handle. The product it is used in is a nutritional supplement, meal replacement shake and want the customer to not have to dig through the powder to find the scoop. The product must have an induction or conduction seal present so the scoop must fit within the cap having this present and not interfere or create open seals/quality issues. Currently the scoop is manufactured seperately from the cap and still could be going forward. We are looking to see if there is some type of snap feature, locking feature, or other means of keeping the scoop secure to the cap. It must be fitted together easily, either through hand application but preferable some type of robotic assembly. We are looking for conceptual drawings, 3D models and a design that can easily be translated into a mold design and manu...

The job is to calculate the amount of air (m/h) and the pressure (Pa) required to cool down a box with a sensor inside and to advise in case optimization is required. Details: 1. The box housing with the sensor inside is modelled in 3D with Solidworks. The Solidworks model will is attached. 2. The box is having a ceramic plate at the bottom and the rest is made from aluminium. 3. All holes seen in the box will be closed with bolts, apart from the socket at the top for the cooling air inlet and the row of holes at the back for escaping of the cooling air. The row at the back can be adjusted for more or less holes, as per the best air flow. The size of the inlet nozzle can also be adjusted as per flow requirements. 4. The cooling air temperature is 48C. 5. The maximum temperature inside the box shall be 80C. 6. The surrounding temperature is 200C 7. Below the 7mm thick ceramic plate a piece of material is constantly touch with 450C temperature. So, we require someone who i...
