How to input objects into the bottom of a water tank.

Click For Summary
SUMMARY

This discussion focuses on designing a dispensing system for a children's game involving colored balls and a water tank. The proposed system utilizes a two-atmosphere container (2-A-C) that alternates between air and water to facilitate the balls' movement. Key components include hydraulic mechanisms for filling and emptying the container, as well as electrical controls for the dispenser and doors. Suggestions for simplification include using a piston or plunger to release the balls and ensuring the design is safe for young children.

PREREQUISITES
  • Understanding of hydraulic systems and their applications
  • Familiarity with buoyancy principles in fluid mechanics
  • Basic knowledge of electrical control systems for automation
  • Experience with mechanical design for child-safe environments
NEXT STEPS
  • Research hydraulic system design for fluid transfer applications
  • Explore buoyancy and fluid dynamics principles in practical scenarios
  • Learn about electrical automation techniques for mechanical systems
  • Investigate child safety standards in toy and game design
USEFUL FOR

Mechanical engineers, product designers, educators in early childhood development, and anyone involved in creating safe and engaging children's games.

I am; unfortunately Dave is no longer a member of the PF community.

Well, the post #20 design, with a return mechanism, would be one way to spoof a buoyancy pmm.
These things can be quite neat as art - a water-feature?

Dave's was a simpler idea which also addressed, indirectly, the main begged question: why not just push the balls in? Why gravity feed? (The grav feed is a common requirement for the buoyancy pmm designs.) Your's has the needed distractions.
