Child Safety Vest with VELCRO Strap Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety garments for vehicle seat belts are often expensive, cumbersome, uncomfortable, and fail to encourage seat belt use among children, leading to stress and increased risk of injury or death during accidents.
Innovation Solution
A lightweight, durable, and comfortable vest designed to easily accommodate vehicle seat belts, featuring VELCRO and snap fastener systems to prevent neck chafing, along with press-on pockets and tether straps for safety, encouraging seat belt use and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If children are restrained by traditional seat belt systems, then safety is improved, but comfort and acceptance deteriorate due to neck chafing and cumbersome design
Solution Approach 1:
The patent introduces a vest as an intermediary device between the child and the seat belt system. The vest includes shoulder pads and positioning features that mediate the interaction between the rigid seat belt and the child's body, distributing pressure and preventing direct contact between the belt and neck, thereby maintaining safety while improving comfort
Solution Approach 2:
The vest incorporates localized features such as padded shoulder areas and specific positioning elements at critical contact points. These local modifications to the garment's structure address the chafing problem at the neck and shoulder regions without compromising the overall restraint function of the seat belt system
2Reliability
If traditional harnesses and garments are used, then safety restraint is achieved, but device complexity and cost increase while appeal to children decreases
Solution Approach 1:
The vest serves multiple functions: it provides the necessary restraint positioning for safety, offers comfort through padding, and acts as an appealing garment that children willingly wear. By combining these functions into a single versatile device rather than multiple separate components, the patent reduces overall system complexity while maintaining safety effectiveness
Solution Approach 2:
The vest is designed as an inexpensive, simple garment that can be easily replaced or modified. The use of basic materials and straightforward construction methods keeps costs down and complexity low, while the vest remains effective for its intended purpose throughout its service life
3Reliability
If seat belt systems are made more restrictive, then safety is improved, but children's acceptance and willingness to wear them deteriorates
Solution Approach 1:
The vest provides localized comfort features at specific areas of contact (shoulders, neck) while maintaining the overall restraint function. This allows the system to be sufficiently restrictive for safety without being overly restrictive in a way that would cause children to reject the entire system
Solution Approach 2:
The vest acts as a mediating layer that translates the restrictive force of the seat belt into a more acceptable form for the child. By positioning and distributing the restraint forces through the vest's structure and materials, the system maintains its safety function while improving the child's willingness to wear it
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The vest promotes comfortable and safe seat belt use by children, reducing stress and injury risk while allowing for customization and visibility, making it appealing and effective in teaching safety habits.
Implementation Method 1
a VELCRO flap fabricated from a soft, fluffy hook and loop material which is fixed adjacent one of its ends to each shoulder of the vest and which is releasably engageable adjacent its opposite end with a VELCRO strip fabricated from rough hook and loop material fixed to each shoulder of the vest, with the flap confining the shoulder strap of a seat belt system positioned therebelow and holding the shoulder strap away from the neck of the wearer of the vest
Implementation Method 2
The secondary restraining and guiding means is located on the front of the vest so as to be positioned at a point mid-sternum of the wearer and comprises a snap fastener system wherein a strap having snap fasteners fixed to each end is releasably engaged with spaced snap fasteners fixed to the vest

AI summary
An inexpensive, multi-purpose, durable garment in the nature of a child's vest for general wear which easily accepts the shoulder strap of a vehicle seat belt system regardless of the child's seated position in the vehicle, is light in weight, easy to put on and take off, comfortable to wear, encourages the habit of seat belt use and is appealing and attractive to children.
