5 Demand Confirmation
5.1 Content of Customized Demands
Customized demands include the following content of customized products:
a) Specifications: specification data of customized consumer products, such as:
volume and space size data, etc.;
b) Materials: information of raw and auxiliary materials required for the
manufacture of customized consumer products, such as: textile fabrics, plates,
adhesives and hardware accessories, etc.;
c) Appearance: information of appearance style demands of customized
consumer products, including optional types and subjective description types,
etc.;
d) Functions: leading functions and auxiliary functions of customized consumer
products;
e) Price: expected price and price range of customized consumer products;
f) Others: delivery and after-sales demands of customized consumer products,
such as: delivery time limits, delivery modes, acceptance standards and
methods, liability for breach of contract, after-sales maintenance and repairs,
etc.
5.2 Quality Control Points of Customized Demands
Customized demands include the following quality control points:
a) Demand description;
b) Demand conversion;
c) Demand assessment;
d) Demand rectification;
e) Demand and order conversion;
f) Storage of order information.
The manufacturers of customization should take the consumers’ customized demands
as the basis for product configuration design; establish a complete product
configuration information model or example, and conduct quality and safety
assessments; formulate a rational configuration design scheme. The configuration
design is carried out in accordance with the following steps:
a) In accordance with the combination of basic modules and functional modules
of a product, establish a product configuration model;
b) Provide users with optional functional demands and matching combinations
of functional demands;
c) Set configuration principles;
d) In accordance with the configuration principles, clarify the functional modules
required for customized products; match them with the basic modules to
generate customized products.
6.2 Variant Design
6.2.1 Product development stage
In the stage of variant design oriented to product development, the manufacturers of
customization should take mature basic-type products as prototypes for the planning
of the development of customized products and product extension design.
6.2.2 Product customization stage
In the stage of product customization, variant design may be divided into product
structure variant design and component parameter variant design, which are carried
out in accordance with the following steps:
a) On the basis of product modularization, based on elements like structural
models, assembly models and product models, conduct product structure
variant design under automation or manual intervention;
b) On the basis of unchanged overall structure, based on the parameterization
and product characteristics, conduct component parameter variant design on
components that need modifications.
6.3 Formulation of Design Scheme
During the formulation of a design scheme, the design and development personnel
should confirm the following content:
a) The requirements for product safety determination in mandatory standards,
and relevant laws and regulations;
a) The manufacturers and consumers confirm the clarity and completeness of
the design input, and the correspondence with the demand information;
b) Clarification and identification of demand information in the design drawings;
c) Review and confirmation of the design scheme and its changes;
d) Confirmation of the trial sample-making by the manufacturers and consumers;
e) Confirmation of the sample testing by the manufacturers and consumers.
