ENGINEERING TEAM PROJECT GROUP 56 SMART DUSTBIN 1

ENGINEERING TEAM PROJECT [ GROUP 56 ] SMART DUSTBIN 1 OBJECTIVES 2 PROBLEM STATEMENT Dustbin overload with garbage and METHODOLOGY CAPITAL COST Purchasing materials Measuring OBJECTIVES Cutting • The device can automatically tie the garbage bag when the bag is almost full. Dust bin (10 gallon) Power window motor (12 V) Steel rod Cabel Selotaper TOTAL = RM 30. 00 = RM 4. 00 = RM 10. 00 = RM 60. 00 =RM 134. 00 Operational Cost Overall Cost = RM 1. 20 = RM 135. 20 Drilling • The tied garbage bag then rolls to the side of the bin when small door at the bin’s wall opened. • The device now closes the shutter door when the bin is empty. Marketing Price Assembling & Fabrication • The garbage bag will be noticeable and new plastic bag will be replaced. Setting up circuit • The device can be easily maintained and no significant energy consumption required. Testing and finalization DESIGN CONCEPT ECONOMIC ANALYSIS Material selection people started to throw rubbish outside dustbin. Cleaners are not working during weekend thus leading to this problem. 4 3 SUPERVISOR: • ASSOC. PROF. ASKURY ABD KADIR TEAM MEMBERS: • MUHAMMAD AFIQ ZIEKRY BIN MOHD SHUKRY • MOHD FAIZ FAHMI B.

CLAMPING MECHANISM FORWARD & REVERSE CIRCUIT 7 Plastic replacement mechanism is an isolated system where the activation of the system is by pressing a button yet activated after second output finishes. PLASTIC REPLACEMENT MECHANISM ENGINEERING ANALYSIS 8 Thus, a=2. 7710 m/s^2 ADVANTAGES • Avoid the dustbin from being overload, thus creating a usable dustbin all the time when the cleaner is not around. • Economically feasible. • Settings and attachment (cage) can be used to suit the environment of the dustbin. INITIAL CATIA DESIGN Stiffness of spring, spring use oil tempered A 229 types of spring, Thus, k=0. 5072 N/mm Deflection of spring x=50. 02 mm Required power supply, P=Tw= 356 k. W Bearing life, use SKF rating: Xd=60*Ld*nd/60*Lr*nr=132. 3 C 10=1. 2 Fd. Xd 1/a thus, choose 02 10 mm deep groove ball bearing 9 CONCLUSION & RECOMMENDATIONS The product is convenient and reach its objectives. Further analysis on all forces acting in the system can further improve the operations of the bin. Metal components are replaced with polymer/plastic components will reduce its weight and produce lightweight product. Using other alternatives of clamping device will ensure the smoothness of operation. Use suitable sensor to obtain more sensitive and reliable result.
