What does the quality control of furniture product design include?

Introduction: to control the quality of furniture products, we must strictly control the product design. The design shall ensure that the design meets the requirements of relevant standards. The National Bureau of quality supervision has a series of mandatory standards for furniture products such as dimensions, materials, processing accuracy and environmental protection.

To control the quality of furniture products, we must strictly control the product design. The design shall ensure that the design meets the requirements of relevant standards. The National Bureau of quality supervision has a series of mandatory standards for furniture products such as dimensions, materials, processing accuracy and environmental protection. Design investigation, market forecast and product decision-making shall be well done; Through preliminary design, model making and construction design. Improve product structure design. The designer shall guide the sample production. After the sample production, the designer shall further verify whether the product meets the design requirements from the aspects of product function, structure, material, processing and decoration, and whether the product specification, structure and materials used are correct; In case of technical and quality problems, the construction drawings shall be modified in time. During batch production, the design representative shall track each process and correct the problems in time.

1、 Product design should meet the requirements of ergonomics. The basic scale of human body and human activity scale are the most basic basis for furniture function design. In this regard, ergonomics has been deeply researched. The design of furniture products shall consider the different requirements and application occasions of users, and study the general range suitable for the basic adaptation of ordinary people. The concept of “percentile” shall be applied in the design of furniture. The suitable range of general-purpose furniture shall be 95%, so that 95% of the people feel that the product is suitable. For special requirements such as star rated hotels and presidential suite furniture, the design scale is beyond the normal scale considering social status, wealth, self-esteem and other factors; Develop special furniture with good stability and high safety for specific groups, such as children, the elderly and the disabled; For schools, hospitals, office furniture, etc., the relevant standards and dimensions shall be fully considered and the design shall be carried out according to the requirements of users.

2、 The use of materials is scientific and reasonable, and meets the requirements of environmental protection. There are many materials used in the production of wooden furniture, of which wood and wood-based panels are the largest. The influence of moisture content change on the size, shape variation and strength of components shall be fully considered in the design of wood for furniture. The base material must be manually dried, and the final moisture content shall not be higher than the equilibrium moisture content of the product location plus 1%. Different styles of furniture are designed by using the natural patterns, color changes and different textures of wood, such as pine, cherry and birch. For example, in the 10 mandatory standards such as GB18584-2001 limit of harmful substances of wood furniture for interior decoration materials promulgated and implemented by China in 2002, the wood-based panels, adhesives and paints used in the production of wood furniture shall meet the limit value requirements of free formaldehyde, benzene, total organic volatiles, heavy metals and other harmful substances.

3、 The structural design of wooden furniture shall be firm and reliable, and the designer shall fully master the production process and parts structure of furniture. Aiming at the quality problems of panel furniture and solid wood furniture, such as the cracking of wood furniture itself, the cracking of panel (finger joint), structure and thin wood composite, the bending deformation of door opening, horizontal plate and vertical plate, the loosening and falling off of tenon and tenon structure, the loosening of disassembly and assembly structure in panel furniture and other quality defects, find out the unreasonable parts of structural design and take measures to solve them. For the fixed structure of wooden furniture, glue joint, mortise joint, straight nail joint, wood screw joint and threaded rod joint shall be adopted. If necessary, auxiliary measures such as triangle wood and connecting wood shall be added. In order to prevent cracks at the material splicing, a straight V-shaped or U-shaped process groove shall be opened at the connection part at the splicing part, and the horizontal parts at the connection part shall be retracted by 1mm ~ 3mm from the longitudinal parts. The surface of the parts in contact with the human body must be smooth, and the edges and corners of the product must be slightly chamfered or rounded.
