Project title: Baby high chair

Project description

Today, there are many baby high chairs in the market and to be used in the restaurant and also at home.Particularly, for family the baby high chair is already become the perfect symbol of the family.But it still can be improved or redesign especially from sustainability design and HCD point of view. It is because some of the baby high chair are not suitable for the height of the table, hard structure and not flexible.

Therefore, this is a good opportunity to create the new baby high chair for applied the HCD and sustainable design,such as easy assembly,user-friendly,multifunction,Eco-friendly and long-term use in this project. This project will consider the characteristic of the child and of course it will be focusing on normal baby only.Subsequently, this project also considers the baby and parents demand, ease-of-use,adjustability,safety,design evaluation in order to get the HCD and sustainable design of a baby highchair.

The parents need a baby high chair with long-term design idea, because it is required to meet the usage of the different growth period of the child.


Through the research, it turns out the biggest stakeholder of the baby high chair is infants and parents. Therefore, I mainly carry out analysis on these two user groups and work out the most authentic demands and feelings of the users. Besides, it is quite favorable for my following design.

Name:Jack Johnson
Age:9 mouth
Johnson is a boy, born for 9 months. He already can perceive different emotion. For instance, he knows what the feeling of hunger and loneliness is. Meanwhile, he can make corresponding response to the external objects through “hubbub” or “cry”, so as to express his own willing. He begins to be curious about the objects around him, and also he is willing to touch them he is interested in. During the dinner time, he is not willing to sit on the baby high chair quietly, because he thinks he is bound and has a feeling of scare. He does not hope his parents are out of his line of sight.

Name:Lene Marlin
Age: 25
Marlin, a young mother, is 25 years old now. Last year, she gave birth to her first child. Now, the child is almost one year old. As she became a mother for the first time, she takes good care of the child, and she always worries that the child may get hurt due to her carelessness. Therefore, she attaches great importance to the safety and comfort when she chooses a baby high chair for her child. She prefers to the wood material. Although the plastic baby high chair does not have advantage in flexibility and coast, she believes that the wood material is more stable and safe, and such material does not do harm to the children.

Name:Michael Brown
Brown is already the father of three children. Therefore, he has accumulated sufficient experience in how to take care of the children. His youngest son is already 2 years old this year. At present, he plans to purchase a new baby high chair. For him, it is important to pay close attention to the growth of the children and establish a harmonious relationship. The family dinner every day has become a quite good exchange opportunity, so it is necessary to get a baby high chair whose height can be easily adjusted so as to meet different height of the table. Under such circumstance, the child can have dinner with his parent and participate in the family exchange.

Reflection and Design value (week 3)

After have an overall understanding of the baby high chair, I find it is necessary to have deep research and analysis on the users in the next phase. Besides, according to the lecture given by Leong, I lay emphasis on analyzing the emotions activity of the users, and exploring what is the users more focus on the core value of the baby high chair.
I have consulted materials related to the infant development. To comprehensively and effectively carry out created personas and empathy maps, I have summarized the need and insight of the users. I believe consulting the material is of great importance, as the infant is a relatively special group. It is relatively weak in conveying self will and demands. Sometimes, the adult cannot completely understand some behavior and actual demands of the infants, so we can understand some change of the infants in the physiological aspect through consulting material, and thus comprehend and speculate the actual demands of the infants to the greatest extent.

Child development – six to nine months

By six to nine months of age, your baby begins to realise they are a separate person surrounded by their own skin. They no longer experience floating in a sea of feelings and needs, where the outside and the inside are all mixed together. They start to understand you are separate from them, and may worry when they can’t see or feel you nearby.

Social and emotional development

Your baby’s ‘insides’ feel more organised to them. They begin to recognise and identify different feelings and sensations – for example, what ‘hungry’ or ‘lonely’ feels like. Other developmental characteristics include:
Desires of their own – for example, wanting to be picked up or given a particular toy.
The ability to recognise the important, familiar people in their world (which also makes them sensitive to strangers).
Enjoyment of being talked to and played with, since this is a very sociable age.
Physical development

Your baby will put everything into their mouth. Their lips and tongue are the most sensitive parts of their body and give them lots of information about shape, texture and taste. Your baby:
Will start to take some mashed solids around this time and, later, some soft finger foods such as toast (under your supervision)
Finds it hard to work out the eating action because they are used to sucking, so keeping the food inside their mouth can be a challenge
May find different food textures strange at first
Is learning they can swallow some bits of the world (such as food) but not others (such as their teddy bear).

Moving about

At some time during these four months, your baby will be able to:
Roll over, from front to back and back to front
Sit alone for a few moments when you put them into a sitting position and then, later, manage to sit alone without toppling over
Do push-ups when on their tummy
Start to move while on their tummy, first ‘commando’ style (pulling along on the arms) and then crawling on all fours
Reach for a rattle and shake it
Swap a toy from one hand to the other
Find their feet, play with them and put them in their mouth.

Seeing and hearing

Your baby will be able to:
Focus on small objects, since their eye muscles will be working well
Develop a perception of depth and, therefore, be afraid of heights and falling
See a drop below them and understand that it is scary (by nine months)
Turn towards familiar sounds and voices
Make sounds themselves, not only verbally but by banging objects together.

Speech and language

While your baby has been cooing and babbling for many weeks, their sounds now take on a closer resemblance to real words. Your baby:
Probably puts a vowel and a consonant together, as in ‘mum’ or ‘bubbub’
Might say ‘mama’ because they can, rather than because they understand the meaning of the word
Will work out how to use the different sounds by noticing how you respond to them
Enjoys making sounds
Experiments with and copies different sounds, such as clicks and lip bubbles, as well as their word-like sounds
Uses lots of different words and sounds to express different emotions
Listens carefully when you speak, and tries to talk back using babbling sounds.

Suggested activities

Your baby loves to touch, grasp and ‘make things happen’. Fun activities, such as shaking or banging objects, help them to understand they have an effect on the world. Conceptually, they are learning about up and down as well as coming and going, and will love to play games that act these things out. Suggestions on encouraging and supporting your baby’s development include:
Babies need interaction with other people much more than play-time with toys.
Talk to them.
Look into their eyes.
Play games like ‘Here is your nose – here is mummy’s nose’.
Play the game of picking up their dropped toy (over and over – babies of this age love it).
Play ‘ah boo’ as you hide your face behind a book or cloth, then say their name when you come out.
Signs that suggest a developmental problem

Children develop at different rates, so if your baby doesn’t do all the things listed in this article, it may be that your child’s development pattern is still within the normal range. However, if your baby is very different from other children, or if you are worried about their development or it seems to go backwards, seek the advice of a health professional. Signs that could suggest a developmental problem include:
Needing help to sit up
Not smiling or laughing out loud
Inability to grasp, hold or shake things
Not reaching out for objects and putting them in their mouth
Not turning to you when you call their name
Resistance to trying ‘solid’ foods
Inability to make a range of sounds
No eye contact
Not showing pleasure when seeing familiar people
Seeming not to recognise mother and significant others.
