Child Booster Harness Assembly for Fit and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seat belt systems and child restraint systems often fail to provide adequate protection due to improper fitting, lack of adjustability, and bulkiness, leading to increased injuries and fatalities, especially among children, as they are not designed to accommodate varying user sizes and are inconvenient to transport.
Innovation Solution
A lightweight restraint system comprising a harness and a booster seat that can be adjusted for different users and vehicles, allowing for secure attachment to vehicle seat belts, with energy-absorbing materials and padding for enhanced safety and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional car seats are used for children under 40 pounds, then safety protection is improved, but portability and convenience deteriorate due to bulkiness and heavy weight
Solution Approach 1:
The restraint system is divided into separate components: a lightweight booster seat and a detachable harness assembly. The harness can be removed and transferred between different booster seats, allowing parents to carry only the lightweight booster while the harness remains in the vehicle. This segmentation resolves the contradiction by separating the bulkiness of traditional car seats from the essential safety function.
Solution Approach 2:
The harness assembly is designed to be universal and compatible with multiple booster seats and vehicle seat belt systems. It can be adjusted to accommodate children of various sizes and can be installed in different vehicles, making it a multi-functional safety device that replaces multiple traditional car seats.
2Adaptability or versatility
If standard seat belts are used for all occupants, then simplicity is improved, but adaptability deteriorates because they cannot accommodate varying user sizes properly
Solution Approach 1:
The harness assembly incorporates adjustable components including removable shoulder straps, adjustable waist belts, and flexible positioning systems that can be customized for each child's size and body shape. This dynamic adjustability allows the same harness to adapt to different users without requiring multiple specialized devices.
Solution Approach 2:
The harness design allows for parameter changes in strap length, positioning, and tension to accommodate different child sizes. The waist belt can be positioned at different heights, and the shoulder straps can be adjusted in length and angle, providing a customized fit for each user while maintaining a single standardized harness design.
3Reliability
If booster seats are used for children above 40 pounds, then portability is improved, but safety protection deteriorates for smaller children under 40 pounds
Solution Approach 1:
The booster seat with detachable harness assembly is designed to be universally applicable to children across a wide weight range. The same booster seat can be used with the harness for children under 40 pounds, and without the harness for older children, making it a multi-functional solution that eliminates the need for different booster types.

AI summary
An improved restraint system is provided. More particularly, the improved restraint system can include a harness and a booster seat. The harness can be attached to a seat belt of a vehicle. The harness can include a shoulder seat belt guide member for attaching a shoulder seat belt and also a lap seat belt guide member for attaching a lap seat belt. The improved restraint system can allow a child who is otherwise unsuitable for using a booster seat alone to use the booster seat in combination with the harness.
