Optimization and Cost-Effective Analysis of a Low-Cost Hand Pump Bottle
Jayanthan Gunarajah
Hand pump bottles dispense liquids such as cleaners and pesticides through a piston pump mechanism. This study optimizes a 1000 ml bottle to cost 45–50 pence, weigh 1.104 kg (including packaging), incorporate recyclable PET/HDPE materials, and ensure durability of components (trigger, snap-fits). Pugh’s matrix, CATIA V5, CES Edupack, and Finite Element Analysis (FEA) guide the design process. Consumer surveys inform ergonomic and environmental enhancements, addressing gaps in cost, sustainability, and user experience. The scalable design offers a practical, market-ready solution for manufacturers.
