3.3  User involvement in the Design 
Process 
User involvement design starts from user analysis, by 
analysing the user's physiology, behaviour and 
psychology to establish the user'sneeds, such as 
interaction needs, self-fulfilment needs, usage needs 
and cultural needs. 
Then, we analyse the data of user needs, design 
and develop product shapes and decorative elements 
to meet the needs of users, and allow users to fully 
develop their creativity through user participation in 
design. 
Through user participation in the design process, 
users can give full play to their own creativity and 
finally complete the design and production of the 
product. The user participation design process is 
illustrated. 
Step 1: User analysis.   
Step 2: Requirements acquisition.   
Step 3: User needs analysis. 
Step 4: Design element development and user 
involvement. 
Step 5: Design realisation. 
3.4  r Demand Acquisition for Chengdu 
Lacquerware Cultural and 
Creative Products 
Today, the number of different types of cultural and 
creative product designs is increasing, and the 
demand for cultural experiences is growing, with both 
users and designers expecting the product to enhance 
the spiritual experience through cultural implantation. 
By accurately tapping into information about user 
needs, translating them into specific elements of 
product design, and presenting external factors such 
as the shape, ornamentation and colour of the product 
in the design of Chengdu lacquerware cultural and 
creative products, the transformation between user 
needs and the characteristic elements of the product 
is further completed. User needs are categorised in 
order to better understand the needs of the target 
users. The first step in acquiring user needs for 
Chengdu lacquerware cultural and creative products 
is to identify the target user group and clarify who the 
product is designed for. In determining the target 
users, this can be done by analysing the background 
information of the user’s identity and through 
questionnaires to locate them (Liu, 2021). The user 
portrait is a way of standardising the target user group 
through questionnaires and user interviews to better 
capture the target users and their real needs, to ensure 
that the product development process does not deviate 
from the user needs, and to use the Kano model user 
needs taxonomy to analyse the target user’s needs 
preferences and measure the user’s satisfaction with 
a certain attribute of the product (Huang, 2021). The 
Kano model was used to analyse the preferences of 
the target users and to measure their satisfaction with 
a particular attribute of the product. This helped the 
designers to accurately position the style, function 
and shape of the Chengdu lacquerware product 
design. 
4  EXTRACTING AND 
RECONSTRUCTING 
ELEMENTS OF CHENGDU 
LACQUERWARE PRODUCT 
DESIGN FOR USER 
PARTICIPATION 
As one of the pearls of intangible cultural heritage, 
Chengdu lacquerware is of great artistic value in 
terms of its production techniques and aesthetic 
characteristics. This chapter first analyses the 
characteristics of the appearance, decorative elements 
and compositional forms of Chengdu lacquerware, 
analyses the data collected on ancient and existing 
products of Chengdu lacquerware, combines the 
regional cultural characteristics of Chengdu 
lacquerware and other factors, and constructs an 
analysis chart of Chengdu lacquerware cultural and 
creative  product  design. Based on user needs and
