Design Lifetime
The design life of a component or product is the period of time during which the item is expected by its designers to work within its specified parameters; in other words, the life expectancy of the item. It is not always the actual length of time between placement into service of a single item and that item's onset of wearout. Another use of the term design life deals with consumer products. Many products employ design life as one factor of their differentiation from competing products and components. A disposable camera is designed to withstand a short life, whilst an expensive single-lens reflex camera may be expected to have a design life measured in years or decades. Long design lives Some products designed for heavy or demanding use are so well-made that they are retained and used well beyond their design life. Some public transport vehicles come into this category, as do a number of artificial satellites and spacecraft. In general, entry-level products—those at the ...

Consumables
Consumables (also known as consumable goods, non-durable goods, or soft goods) are goods that are intended to be consumed. People have, for example, always consumed food and water. Consumables are in contrast to durable goods. Disposable products are a particular, extreme case of consumables, because their end-of-life is reached after a single use. Consumables are products that consumers use ''recurrently'', i.e., items which "get used up" or discarded. For example consumable office supplies are such products as paper, pens, file folders, Post-it notes, and toner or ink cartridges. This is in contrast to capital goods or durable goods in the office, such as computers, fax machines, and other business machines or office furniture. Sometimes a company sells a durable good at an attractively low price in the hopes that the consumer will then buy the consumables that go with it at a price providing a higher margin. Printers and ink cartridges are an example, as are cameras and film ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Design
Industrial design is a process of design applied to physical Product (business), products that are to be manufactured by mass production. It is the creative act of determining and defining a product's form and features, which takes place in advance of the manufacture or production of the product. It consists purely of repeated, often automated, replication, while craft-based design is a process or approach in which the form of the product is determined by the product's creator largely concurrent with the act of its production. All manufactured products are the result of a design process, but the nature of this process can vary. It can be conducted by an individual or a team, and such a team could include people with varied expertise (e.g. designers, engineers, business experts, etc.). It can emphasize intuitive creativity or calculated Evidence-based design, scientific decision-making, and often emphasizes a mix of both. It can be influenced by factors as varied as Raw material, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO 15686
ISO 15686 is the in development ISO standard dealing with service life planning. It is a decision process which addresses the development of the service life of a building component, building or other constructed work like a bridge or tunnel. Its approach is to ensure a proposed design life has a structured response in establishing its service life normally from a reference or estimated service life framework. Then in turn secure a life-cycle cost profile (or Whole-life cost when called for) whilst addressing environmental factors like life cycle assessment and service life care and end of life considerations including obsolescence and embodied energy recovery. Service life planning is increasingly being linked with sustainable development and wholelife value. The objective of service life planning is to provide reasonable assurance that the estimated service life of a new building on a specific site, with planned maintenance, will be at least as long as the design.

Throwaway Society
The throw-away society is a generalised description of human social concept strongly influenced by consumerism, whereby the society tends to use items once only, from disposable packaging, and consumer products are not designed for reuse or lifetime use. The term describes a critical view of overconsumption and excessive production of short-lived or disposable items over durable goods that can be repaired, but at its origins, it was viewed as a positive attribute. Origin of the term In its 1 August 1955 issue, ''Life'' published an article titled "Throwaway Living". This article has been cited as the source that first used the term "throw-away society". Rise of packaging waste The last century of economic growth saw both increased production and increased product waste. Between 1906 (the start of New York City waste collections) and 2005 there was a tenfold rise in "product waste" ( packaging and old products), from per person per year. Containers and packaging now represen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Source Reduction
Source reduction is activities designed to reduce the volume, mass, or toxicity of products throughout the life cycle. It includes the design and manufacture, use, and disposal of products with minimum toxic content, minimum volume of material, and/or a longer useful life. Synonyms Pollution prevention and toxics use reduction are also called source reduction because they address the use of hazardous substances at the source. Examples * Reusable packaging - for example the use of a reusable shopping bag at the grocery store; although it uses more material than a single-use disposable bag, the material per use is less. * Overpackaging - Some packaging uses more materials than is necessary for product containment and protection. Redesign can often reduce the size and materials usage in packaging. Procedures Source reduction is achieved through improvements in design, production, use, reuse, recycling, and through environmentally preferable purchasing (EPP). A Life-cycle assessm ...

Service Life
A product's service life is its period of use in service. Several related terms describe more precisely a product's life, from the point of manufacture, storage, and distribution, and eventual use. Service life has been defined as "a product's total life in use from the point of sale to the point of discard" and distinguished from replacement life, "the period after which the initial purchaser returns to the shop for a replacement". Determining a product's expected service life as part of business policy (product life cycle management) involves using tools and calculations from maintainability and reliability analysis. Service life represents a commitment made by the item's manufacturer and is usually specified as a median. It is the time that any manufactured item can be expected to be "serviceable" or supported by its manufacturer. Service life is not to be confused with ''shelf life'', which deals with storage time, or with technical life, which is the maximum period during ...

Repairability
Repairability is a measure of the degree to and ease with which a product can be repaired and maintained, usually by end consumers. Repairable products are put in contrast to obsolescence or products designed with planned obsolescence. Repairability index Some private organizations and companies, mostly affiliated with the right to repair movement, assign repairability scores to products as a way of communicating to consumers how easily repairable the product is. France Since 2021, all electronic devices sold in France have been required to report a ''repairability index'' (french: Indice de réparabilité) which rates how repairable a product is on a scale from 0 to 10, primarily to prevent corporate greenwashing and encourage environmental transparency. Products are evaluated on 5 key areas: documentation, disassembly, spare parts availability, spare part pricing, and product specifics. Limitations The repairability index scoring process isn't bulletproof, though—m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planned Obsolescence
In economics and industrial design, planned obsolescence (also called built-in obsolescence or premature obsolescence) is a policy of planning or designing a product with an artificially limited useful life or a purposely frail design, so that it becomes obsolete after a certain pre-determined period of time upon which it decrementally functions or suddenly ceases to function, or might be perceived as unfashionable. The rationale behind this strategy is to generate long-term sales volume by reducing the time between repeat purchases (referred to as "shortening the replacement cycle"). It is the deliberate shortening of a lifespan of a product to force people to purchase functional replacements. Planned obsolescence tends to work best when a producer has at least an oligopoly. Before introducing a planned obsolescence, the producer has to know that the customer is at least somewhat likely to buy a replacement from them (see brand loyalty). In these cases of planned obsolescence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maintainability
In engineering, maintainability is the ease with which a product can be maintained to: * correct defects or their cause, * Repair or replace faulty or worn-out components without having to replace still working parts, * prevent unexpected working conditions, * maximize a product's useful life, * maximize efficiency, reliability, and safety, * meet new requirements, * make future maintenance easier, or * cope with a changing environment. In some cases, maintainability involves a system of continuous improvement - learning from the past to improve the ability to maintain systems, or improve the reliability of systems based on maintenance experience. In telecommunication and several other engineering fields, the term maintainability has the following meanings: * A characteristic of design and installation, expressed as the probability that an item will be retained in or restored to a specified condition within a given period of time, when the maintenance is performed by prescribed p ...

Interchangeable Parts
Interchangeable parts are parts ( components) that are identical for practical purposes. They are made to specifications that ensure that they are so nearly identical that they will fit into any assembly of the same type. One such part can freely replace another, without any custom fitting, such as filing. This interchangeability allows easy assembly of new devices, and easier repair of existing devices, while minimizing both the time and skill required of the person doing the assembly or repair. The concept of interchangeability was crucial to the introduction of the assembly line at the beginning of the 20th century, and has become an important element of some modern manufacturing but is missing from other important industries. Interchangeability of parts was achieved by combining a number of innovations and improvements in machining operations and the invention of several machine tools, such as the slide rest lathe, screw-cutting lathe, turret lathe, milling machine and metal ...

Durability
Durability is the ability of a physical product to remain functional, without requiring excessive maintenance or repair, when faced with the challenges of normal operation over its design lifetime. There are several measures of durability in use, including years of life, hours of use, and number of operational cycles. In economics, goods with a long usable life are referred to as durable goods. Requirements for product durability Product durability is predicated by good repairability and regenerability in conjunction with maintenance. Every durable product must be capable of adapting to technical, technological and design developments. This must be accompanied by a willingness on the part of consumers to forgo having the "very latest" version of a product. In the United Kingdom, durability as a characteristic relating to the quality of goods that can be demanded by consumers was not clearly established until an amendment of the Sale of Goods Act 1979 relating to the quality ...
