Fingerless Crawling Gloves With Thumb-Index Finger Constraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Babies and young children, as they develop motor skills and become mobile, face increased risks of swallowing harmful objects due to their tendency to put objects in their mouths, necessitating protective measures to prevent such actions.
Innovation Solution
A fingerless glove design featuring a stiffening member between the thumb and finger holes to inhibit the proximity of these digits, along with a brace member on the palm side to prevent grasping, combined with a non-slip and abrasion-resistant palm portion, ensuring mobility while preventing object pickup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a baby is allowed free hand movement to explore objects, then motor skill development and sensory learning are improved, but the risk of picking up and swallowing harmful objects increases
Solution Approach 1:
The glove divides the hand into functional zones: the palm and fingers remain free for exploration, while the thumb and index finger are constrained by the stiffening member. This segmentation allows the baby to maintain general hand mobility for crawling and grasping larger objects while preventing the specific thumb-index finger combination needed for picking up small harmful objects.
Solution Approach 2:
The stiffening member acts as an intermediary element between the thumb and index finger, physically blocking their ability to come into close proximity. This mediator prevents the harmful action of picking up small objects while allowing the baby to continue using their hands for other purposeful activities.
2Object-affected harmful factors
If the thumb and index finger are constrained from touching, then the ability to pick up small objects is prevented, but fine motor skill development may be limited
Solution Approach 1:
The glove applies different levels of constraint to different parts of the hand. The stiffening member provides strong local constraint only in the thumb-index finger region, while the rest of the hand maintains full freedom of movement. This localized approach prevents harmful object pickup without interfering with overall hand dexterity and fine motor development.
Solution Approach 2:
The glove provides more constraint than absolutely necessary for safety by completely blocking thumb-index finger contact, but this excessive constraint is acceptable because it prevents the specific harmful action of picking up small objects. The partial freedom maintained in other hand regions ensures that fine motor skills can still develop through alternative grasping motions.
3Object-affected harmful factors
If a rigid structure is added to prevent finger movement, then safety from harmful objects is improved, but comfort and flexibility of the glove decreases
Solution Approach 1:
The glove structure is segmented into rigid and flexible portions. The stiffening member provides rigidity only in the specific area where thumb and index finger contact would occur, while the rest of the glove material remains flexible and comfortable to wear. This localized rigidification maintains overall glove flexibility and comfort.
Solution Approach 2:
The glove is constructed using flexible materials that can conform to the baby's hand shape and movements, while the stiffening member is integrated as a thin, flexible element that only restricts thumb-index finger proximity. This approach ensures the glove remains comfortable and adaptable to the child's hand while providing the necessary safety function.

AI summary
A glove includes a fingerless glove body having a stiffener between the thumb and pointer finger to prevent a person from picking up objects between the thumb and pointer finger and putting them into her mouth. A brace is also provided to prevent the wearer from touching the palm of the glove with their fingers to further prevent a person from pickup up objects by making a fist and putting the objects into her mouth. The glove further provides abrasion resistance and slip resistance, such as for a crawling baby.
