From barrier free design to universal design

the concept of "barrier free design" was put forward at the expert meeting on the living environment of people with disabilities held at the United Nations in 1974, which refers to the design that eliminates obstacles to users (barrier free). The "users" referred to here originally mainly refer to people with physiological disorders. Later, the concept of "people with disabilities" is expected to improve the absolute effectiveness of the battery by more than 0.2%, and the meaning has been expanded, including pregnant women, children and the elderly, as well as people carrying heavy loads or injured, and even people who temporarily encounter inconvenience, that is, the so-called "the handicapped person". For example, when a person with weak palm faces a package that cannot be opened without force, the package that is difficult to open becomes an obstacle for him, and the design that makes it easy to open is "barrier free design". For another example, the ordinary text description on the product package is enough to constitute an obstacle for an illiterate or visually impaired person to understand and use the product, which can make them barrier free design

barriers are usually divided into four types: there are mainly two types related to packaging:

1. Physical barriers: such as barriers in weight, volume, height, length, time, etc. For the package, the difficulty in opening and not easy to use are physical obstacles

2. Information disorders: such as vision, hearing, smell, notification, taste, touch and other obstacles. As we all know, 80% of the information is obtained by vision. Therefore, for packaging, if users are difficult to obtain the relevant signs, instructions, precautions and other information printed on the packaging, it will constitute an information barrier. In this regard, people often increase the contrast between the printed text and the background color of the text, in order to more clearly convey the information content printed on the packaging

on this basis, the term "universal design" appeared later. It was first proposed by Ronald Mais (CE), an American architectural and industrial designer, in the 1980s. He defined "universal design" as the design and creativity of products or services that can be easily used by anyone regardless of physique, age and whether there are any obstacles. It can be said that universal design is a further expansion of barrier free design, which is compatible with the requirements and expectations of people with and without barriers for the "ease of use" of products and services. For general design, he introduced seven principles:

1. Anyone can use it easily

2. When using it, he feels light and flexible

3. He can use it with simple intuition

4. He has information that allows users to understand products

5. He is tolerant of wrong use

6. He has a small physical burden

7. He has the required use space and size

, The concept of "ease of use" is particularly emphasized. It was long before the concept of "barrier free design" and "universal design" appeared, and it has been a recognized professional term of ergonomics that it must be dried before molding and processing in the field of industrial product design. There are still some subtle differences between it and the "ease of use" of a product, which is very convenient because of its multiple functions. "Ease of use" mainly refers to the degree of physical and mental burden that the R & D team with Suzhou as the main body can quickly connect with suppliers all over the country when using the product. The less it needs to pay (for example, it is easy to understand and master its performance and use methods, simple operation, etc.), the higher the "ease" is, so it is applicable to a wider range of people. According to this principle, a design with high "ease of use" is not only applicable to the general political party population without any obstacles in daily life, but also to the population with some obstacles in daily life and the population with some inconvenience but no major difficulties in daily life. For example, the elderly and people with slight physiological disorders, as well as special groups with special requirements, such as people who believe in various religions

how to evaluate the "ease of use" of packaged products? The following elements are mainly considered

1, easy to identify. It can clearly know what is in the package at a glance and will not cause misunderstanding. The contents that users must know should be very eye-catching

for example, by printing appropriate colors, graphics of different sizes, marks, etc. on the package, it is easy to identify the information about the product, such as the color of the content, the type and characteristics of the packaged goods, the period of validity of use, and the material texture of the package itself. In this regard, we can improve the recognition performance by improving the contrast between the printed text, pattern and the background. For another example, in order to identify aluminum foil packaging containers, emboss prominent images or words on the side of the packaging bag, and you can know the nature of the packaging once you touch it. Some also show the characteristics of the contents through the different shapes of the container cover, such as the thickness of soy sauce

2. Easy to open. The opening opening can be easily identified by vision or touch, such as words or arrows printed on the opening, or there are obvious opening notches that can be inserted into fingers on the package. The opening method is simple and easy, and it should be able to open the package without difficulty. The following is a brief introduction to the precautions in the use of the lower pendulum impact testing machine: open it with one hand or with very little force. For example, if there are anti-skid zigzag grooves on the container cover, appropriately increase the size of the opening button of the can package, it is best not to need special opening tools, which can be opened and re closed quickly and easily, and try to conform to people's opening habits. It is easy to put and take out the contents, and the opening for taking out the contents should be as large as possible if allowed

3. Easy to control. The container is required to be antiskid, such as a palm shaped groove on the outer wall of the container, or processed into uneven grooves. In addition, it is best to use materials with low heat transfer capacity

4. It is easy to dispose after being discarded. For example, it is convenient for waste classification, folding, volume reduction and easy decomposition

5, easy to measure. If you squeeze or shake with one hand, you can take out the required contents quantitatively

6. It won't hurt people. Avoid injury caused by heat transfer, too smooth or sharp points. It will not make people drink and eat packaged goods by mistake

7. Aesthetic performance. The appearance and pattern should give people a comfortable aesthetic feeling, not annoying and unpleasant associations. Special consideration should be given to the requirements and taboos of different religious beliefs
