What are the similarities and differences between modern home design and ancient home design?

1. The mortises and tenons of ancient furniture are handmade. It is basically square.

At present, mortise and tenon structure is mainly made by machine, that is, mortise and tenon machine which can be mass-produced. Luban Ancient Books records the basic dimensions and patterns of commonly used furniture in detail, which can be used as a reference for modern carpenters. Nail technology was not widely used in ancient times, because in ancient China, wood was not as expensive as it is now, but rare and expensive.

2. Modern furniture design is more in line with human needs, the technology is more complicated, and the comfort has been greatly improved.

The appearance design of modern furniture is more in line with human performance, and ergonomics provides a reasonable and scientific digital scale reference for the appearance design of furniture. For example, the human comfortable sitting posture scale provides scientific numerical parameters for the design scale of leisure seats, and defines the height, width, depth, armrest height and backrest height and inclination of comfortable seats.

3. Different furniture materials can form different human feelings.

Ergonomics technology provides a scientific basis for furniture material design. Modern furniture design fully grasps the perceptual relationship between people and things, which is helpful to improve the comfort of furniture. For example, hard materials, such as steel and glass, give people a feeling of being hard to touch. When the human body is under pressure for a long time, it will inevitably cause discomfort, so it is not suitable as a material for human contact, such as seats, stools and mattresses. Cloth, sponge, etc. Leather and other materials are soft and comfortable, and long-term contact with human pressure can reduce stiffness and discomfort, which is suitable for the design of benches and mattresses. In addition, different materials can adjust the temperature of different materials such as glass and metal, which is cold in winter and not suitable for direct contact with human body; Wood, bamboo and organic plastics have more stable heat transfer performance, which is warm in winter and cool in summer. More suitable for direct contact with the human body.

4. Modern furniture design is more rigorous in stability, firmness and safety protection design.

Ergonomics studies the basic dimensions of people. When people's activities exceed a certain range or do not meet the requirements, fatigue, instability and discomfort will occur, which will lead to potential safety hazards. The creation of furniture must strictly follow ergonomics to avoid unfavorable factors and cause safety accidents.
