The principle

Due to a physical disturbance, a fluid’s viscosity decreases or increases (reversible)

Due to time, a fluid acts more elastic (short times) or more viscous (long times)

When a fluid is spun around a rod, it will move inward, ascending the rod

In a siphon system, a fluid sustains “liquid strings” to self empty

parent feedback survey Respondent 1

Respondent 2

MOM, 3 kids — 11, 9, 7 years Suburban home Does not use night lights. Has dimmer switches on lights.

MOM, 2 kids — 3 years, 13 months Suburban home Does not use night lights. Uses lavender oil to aid in sleep.

What’s the most difficult part of getting you children to sleep? “The oldest just wants to stay up. He has bad dreams and is afraid to go to sleep.”

What’s the most difficult part of getting you children to sleep? “My oldest has never had trouble sleeping. But the youngest has had trouble sleeping from day one. He can not seem to just lay down and fall asleep, plus he’s a very light sleeper, so any noise wakes him up. He usually goes to bed before our oldest (they share a room), so if we aren’t quiet enough when going in to put the oldest to sleep, he will wake up and then not be able to fall back asleep.”

What specific reasons do your children give for their fear? “My youngest and oldest like to have a dim light on in their rooms. Neither one likes it too dark because they say it gives them bad dreams. My youngest gets up in the middle of the night and then climbs into bed with us because her room it too dark.” Critiques of night lights on the market — “The fluorescent bulbs from the track lighting get hot if left on all night. Sometimes it is too bright, even on dim.” As a parent, what would you like to see in a night light? “One with a light sensor that dims and then turns off after a period of time and also responds to movement if child wakes up and then goes back off after a period of time. I also don’t want to spend more than $20.”

INSIGHTS

Many parents don’t consider a night light essential item for their children. This may be because they don’t want their children to develop a dependency. This may be because a night light doesn’t seem to serve a purpose or personal needs of the child.

Why don’t you use a night light? “If you got used to having one and required one to sleep at night, then you’d really have trouble sleeping in a place that didn’t have one. You’d either have to bring one with you everywhere you traveled, or you’d not get sleep.” As a parent, what would you like to see in a night light? “Honestly, I have no idea. Since we don’t use one, I would have no idea what I would want in one.”

A night light should be personal, and it should provide comfort for the child. A night light should turn itself off to save energy.

sensory research The tactile system from

Sensory Integration and the Child: Understanding Hidden Sensory Challenges

a. jean ayres, jeff robbins

“The tactile system is the largest sensory system, and it plays a vital role in human behavior, both physical and mental.”

“Sensory stimulation and motor activity during childhood will ‘mold’ interconnections to form motor processes.”

“There must be light for the visual system to develop the interconnections needed for visual perception.”

Why a tactile, rheological night light? By stimulating the tactile sense with our night light, the child will be able to sense that the stimulus is not dangerous, but comforting. Simultaneously playing, touching, and holding onto Twinkle will help the child develop their motor skills and build more interconnections that will then help develop sensory and motor processes. Not only will Twinkle help with the child’s development, it has been proven that touch reduces stress and decreases anxiety levels. *see citations

design considerations

price/quality

Security/safety

Parents are willing to invest in a quality night light that ensures a comfortable night of sleep for their child.

Ideally, the light should be easily portable for kids to use in any room in their home. The design objective is to instill security and confidence for children in the dark.

Safe materials and an efficient use of energy are the first priorities.

TWINKLE

twinkle The device promotes healthy sleeping behavior in kids, and it is the perfect compromise between price, quality, security and safety. Parents are seen as a consumer, so many times, they aren’t designed with kids in mind (even though they are the user). Therefore most night lights that are on the market are more focused on decor than the needs of the kids.

consumer consciousness The overall look and feel of the product should cater to the likes of children, but also the standards (regarding safety and quality) of their parents. Colors, form, and ergonomics are taken in complete consideration.

context


the story She lay in her bed, smiling as daddy finished the story. He started to get up, and she asked him for one more story, hoping to keep the lights on just a little bit longer. Her father smiled and turned to her, reassuring her that nothing bad would happen. He went to her nightstand and picked up a star and handed it to her. She squeezed the star. It illuminated and emitted a soft, comfortable glow. Her father turned on the other stars and then said, “Good night, princess.” His daughter replied, “Good night, daddy.” He turned off the light, gently closed the door, and carefully walked away. She held the star in her hands and smiled at the chubby shape that gave off a comforting light. She held onto the night light and her eyes closed as she fell asleep. Later that night, she awoke. “Potty,” she thought. She looked at the door, hesitant to leave her room, She looked at the star beside her and said, “I can do it!” She held onto the star and marched confidently to the bathroom. “The hallway isn’t that scary anymore,” she thought as she made her way back. She stood in her doorway, gazing into her room. The warm lights of the stars welcomed her back and she felt comforted and safe. She climbed up into her bed and pulled her blanket close to her, happy that she had conquered the shadows in the hallway. She drifted off once again into a deep slumber, with the star in her embrace.
