Purposeful, cost effective, safe product design supporting sustainable environment works as a catalyst for viability in engineering multiple applications with continued attention to reuse, flexibility in maintenance and environmental constraints. Engineering research analysis expands product applications within known legal parameters. Modest to major product engineering changes include interchangeable parts, moveable manufacture locations, use of by‐products, and alternate packaging. All current methods of manufacture that are compliant and that keep appraised of anticipated regulatory changes use integrity in their engineering design and design support which lessens collateral damages.
Design for Testability
Product design quantitative analysis and qualitative analysis is integral in determining if a product is created. Knowledge of sources of raw materials, recycled materials, and shared production facilities play a part in production design testing and quality of product. Anticipation of competition gives rise to refining of methodology of production and new types of testing needed over time. Manufacture flexibility application tests for pilots and of extrapolated uses help redefine products. The worst case scenario is creating a product of such complexity that there are no competent tests available and thus creating a total waste product.
Design and Test for Service and Maintenance
Human use, manufacture use, and equipment use factors combine many different tests. Cultural tests are important from the name of a product to ease of use and repair. Reliability of product includes promised and desirability of length of service. If reuse probability is high and application is broad, then tests include upgrade factors, resource reuse factors, and development factors. An oil and filter change, or a car brake repair, or a flushing toilet repair package is likely to find a larger market if it is easily accessible, will fit unilaterally and has simple, correct directions for removal and installation. Large products must consider movement and workers available for maintenance specific to the product such as tower cranes.
It is desirable that a product is designed so that when the product breaks down, it is cheaper for consumers to fix it rather than to buy a new one. This would also contribute to a reduction in solid waste stream.
