LCA system boundaries define which life cycle stages are included in the assessment. A "cradle-to-grave" analysis covers the entire product life, from raw material extraction through manufacturing, use, and final disposal. In contrast, a "cradle-to-gate" assessment is a partial LCA that ends when the product leaves the factory gate, excluding the use and disposal phases.

Design for Disassembly (DfD) is a design strategy focused on enabling the easy and cost-effective separation of a product's components and materials at its end-of-life. By prioritizing non-destructive separation, DfD facilitates repair, reuse, remanufacturing, and high-purity recycling. Key techniques include using mechanical fasteners over adhesives, modular construction, and clear material labeling to maximize value recovery.

The International Ergonomics Association divides the discipline into three primary domains of specialization: physical ergonomics focuses on human anatomical, anthropometric, physiological, and biomechanical characteristics as they relate to physical activity, cognitive ergonomics concerns mental processes like perception, memory, and reasoning, and finally organizational ergonomics deals with the optimization of sociotechnical systems, including organizational structures, policies, and processes.

The 1.5 sigma shift is an empirical correction used in Six Sigma calculations to account for the long-term dynamic variation of a process. It posits that over time, a process mean will tend to drift by about 1.5 standard deviations from its short-term centered position. This shift is the reason a 6 sigma process corresponds to 3.4 DPMO, not the theoretical 2 defects per billion.

Uma categorização padronizada de satélites artificiais baseada em sua massa úmida, incluindo o combustível. As classes principais são minissatélites (100–500 kg), microssatélites (10–100 kg), nanossatélites (1–10 kg), picossatélites (0,1–1 kg) e femtossatélites (<100 g). Essa classificação fornece uma linguagem comum para engenheiros, fabricantes e provedores de lançamento definirem a escala da missão, os requisitos técnicos e as estimativas de custo.

O Design para o Meio Ambiente (DfE), também conhecido como ecodesign, é uma abordagem proativa para o desenvolvimento de produtos e processos que minimiza os impactos ambientais e na saúde humana ao longo de todo o ciclo de vida do produto. Ele integra considerações ambientais desde os estágios iniciais do projeto, juntamente com fatores tradicionais como custo e desempenho, para prevenir a poluição e conservar recursos desde o princípio.

Life-Cycle Assessment (LCA) is a systematic methodology for evaluating the environmental impacts associated with all stages of a product's life. This "cradle-to-grave" or "cradle-to-cradle" analysis considers raw material extraction, processing, manufacturing, distribution, use, repair, maintenance, and final disposal or recycling. It quantifies inputs like energy and raw materials and outputs like emissions to air, water, and soil.

As baterias de estado sólido substituem o eletrólito líquido ou gel polimérico das baterias convencionais por um material sólido condutor de íons, como uma cerâmica ou um polímero sólido.

Six Sigma is a quality management methodology aiming for near-perfection. A process operating at a "six sigma" level has a yield of 99.9997%, meaning it produces only 3.4 Defects Per Million Opportunities (DPMO). This standard corresponds to a process where the nearest specification limit is six standard deviations away from the process mean, accounting for a 1.5 sigma shift in the mean over time (refer to the specific details on the debated 1.5 sigma shift as an empirical observation).

Rapid prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer-aided design (CAD) data. In iterative design, it allows for fast creation of tangible models for user testing and stakeholder feedback, enabling quick design refinements before committing to expensive tooling and manufacturing processes.

Electrostatic actuation is a primary method for inducing motion in MEMS. It utilizes the attractive force between two electrodes separated by a dielectric gap when a voltage is applied. The force is proportional to the square of the voltage and the capacitance gradient. Common designs include parallel-plate capacitors for out-of-plane motion and comb drives for large in-plane displacement.

A equação de levantamento do NIOSH é uma ferramenta utilizada por profissionais de saúde e segurança ocupacional para avaliar o risco de lesões musculoesqueléticas associadas a tarefas de levantamento manual. Ela calcula um Limite de Peso Recomendado (LPR) para uma tarefa específica, representando o peso máximo que um trabalhador saudável poderia levantar sem aumento do risco de lesão lombar, considerando fatores como a geometria e a frequência da tarefa.

Um conjunto de nove princípios fundamentais para o design sustentável, desenvolvido por William McDonough e Michael Braungart. Eles defendem o direito da humanidade e da natureza de coexistirem, reconhecem a interdependência, respeitam as relações entre espírito e matéria, assumem a responsabilidade pelas consequências do design, criam objetos seguros e de valor duradouro, eliminam o desperdício, dependem dos fluxos de energia natural e compreendem as limitações do design.
