      Hello Everyone,

      I am a university student. I wish to implement a system that generates energy from the user.

      I have the brief design sorted:

      • A rectangular frame is used to support all the components and weights used
      • A pulley system is used to provide a means for the user to pull a weight up and down
      • The rotation of the pulley is transferred to a shaft
      • The shaft is connected to a motor
      • The motor is therefore run by the users energy
      • The output voltage of the motor is fed into electronics where the resulting energy is stored
      I specifically require advice upon the mechanical aspect of this project. I wish to make a system that is:
      • Efficient
      • Feasible to implement within 3 months
      • Can handle a weight of 10kg
      Current component parameters are:
      • Motor with 15V rated output and 6mm diameter shaft
      • Frame material is 45mm-by-45mm Rexroth beams
      I have provided some basic design sketches to give you a visual idea of what I am thinking:

      The first image is the frame.

      The second image is a basic representation of how I wish to connect the components together. Sorry but it is sideways, and must be rotated 90 degrees anti-clockwise.

      As shown in the second image, I wish to screw the motor under the middle beam, connect it to a coupling shaft, have the coupling shaft connect to the pulley, have the whole shaft supported by hook-like supports, and have the pulley rotate by having the cable pulled up and down by the user on one end and connected to a weight on the other.

      Please give feedback on my design, and I need better ideas so I can improve the project. I am primarily an electronics and electrical engineer so my knowledge in mechanical design is slightly lacking.

      What are you trying to achieve?

      If you're looking to generate useful electricity, the amount that can be generated by a human in such a setup is very limited. Also, if the user is pulling the cable and lifting the weight, the resistance of the generator (not a motor) will increase the amount of work he has to do.

      Not feasible, but a fun concept to be sure. Or maybe you're a superhero or something :)).
