Tupa‐Project deliverables for Logistic Environment Requirements CEEES conference Management of Environmental Stresses 26th of Septemeber 2008 Background The goal of project was to build a general methodology for cost effectively manufactured transported and assembled environmentally compatible product and packaging. The general process description design and developed methodology may be applied and at product system or subsystem level with the emphasis on mechanical structure affected by environmental loads. Focusing on : Integration of product mechanical design and product packaging Cost efficient manufacturing, Profitable storage and transportation Tailored final assembly Optimized total cost structure of product Overall cost structure understanding Target setting Measure and analyze the real environmental conditions of different common transportation methods and routes around the world Compare of collected data with current test specifications and methods To create generic guidelines for packaging design requirements and processes to cover quality targets and optimize designs against cost Update package test specifications and methods to reflect actual conditions and existing delivery model requirements Methodology Product design Analysis of properties of the product and various design solutions Analysis of the effects on the critical transportability properties DESIGN REQUIREMENT PHASE ENGINEERING Design of the specification for the critical transportability properties Package design Description of the fragile/sensitive properties of the product VERIFICATION Measurements •Moisture •Shock •Temperature • RD298 ShockLog recorder with RD299 HPT sensor • iButton DS1923 Hygrochron temperature and humidity logger Stresses and design requirement Stess Design requirement Moisture protection High/Low temperature Stacking strenght Storage Humidity and dipping Mass distribution of the product Static compression Size and dimensions Corrosion protection in time Shock absorbing elements of the package Vibration and product. Shocks Strenght of product chassis Transportation Air Preasure Design of corrosion protection Dynamic compression Strnght of pallet design Shocks and bumps Mass distribution of the product Rain Size and dimensions Handling High/Low temperature Deliverables Most severe stresses MOISTURE o By condense in sea and air transportation o Mechanical stresses SHOCK and BUMB o In loading and unloading of truck, plane or ship o Rough seas VIBRATION o During sea and truck transportation, low frequencys and high frequencys in air freight o Most common rootcause of long term reliability, because of shot test sycles in verification phase Deliverables Prosess Packaging design should be a solid part of mechanical design Definition of clear overlapping in reguirement engineering Define fixed resources for packaging design and responsibility in reguirement engineering in product development phase Cost understanding Cost optimisation should be iteration between mechanical and logistic requirements Enviromental legislation of product packages is giving clear targets and supports overall cost targets and should be implemented to requirement engineering of the product Questions?
