Removable Belt-Positioning Seat for Child Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current booster seats are large, bulky, and difficult for children to carry, requiring multiple purchases as children grow, and existing solutions do not address the need for a cost-effective, flexible child safety seat adaptable to different age configurations.
Innovation Solution
A child safety seat design featuring a seat base and a removable belt-positioning seat that can be configured to accommodate children of various ages, with a backrest attachable for younger children and detachable for older children, allowing the belt-positioning seat to be used independently, and featuring a storage mechanism for the belt guide to facilitate easy use and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If booster seats are designed to be large and bulky to accommodate growing children, then the service life of the seat is extended, but the portability and ease of carrying deteriorates
Solution Approach 1:
The booster seat is divided into two separable components: a base unit and a belt-positioning seat. This segmentation allows the belt-positioning seat to be removed and carried independently, improving portability while the base unit remains stationary. The segmented design enables different usage scenarios - together for extended service life, separated for ease of carrying.
2Ease of manufacture
If booster seats are designed as single large units, then manufacturing cost is reduced, but adaptability to different age configurations deteriorates
Solution Approach 1:
The booster seat incorporates dynamic reconfigurability through removable and attachable components. The belt-positioning seat can be detached from the base unit and reattached as needed, allowing the system to adapt between different age configurations (younger children needing full support vs. older children needing only belt positioning). This dynamic design provides versatility without requiring multiple separate seats.
3Ease of operation
If belt guide is permanently protruding for easy belt routing, then ease of operation is improved, but device complexity and storage space requirements worsen
Solution Approach 1:
The belt guide is designed as a movable component that can be deployed when needed for belt routing and retracted into a storage cavity when not in use. This dynamic mechanism allows the belt guide to transition between protruding (for ease of operation) and stowed (for reduced complexity and space) states, resolving the contradiction between operational ease and structural simplicity.
4Adaptability or versatility
If multiple booster seats are purchased for different age groups, then adaptability to different age configurations is improved, but loss of substance and cost increase
Solution Approach 1:
The booster seat is designed as a universal system that can serve multiple age groups through reconfiguration. The base unit combined with the removable belt-positioning seat creates a multi-functional device that adapts to different child sizes and ages. This universality eliminates the need to purchase multiple separate booster seats, reducing overall cost and material consumption.

AI summary
A child safety seat includes a seat base and a belt-positioning seat. The seat base has a bottom surface suitable for placement on a vehicle seat, and two armrests protruding upward from an upper surface of the seat base. The belt-positioning seat is installable in a receiving region of the seat base between the two armrests and removable therefrom for independent use, the belt-positioning seat including a seat body having a bottom surface adapted to be placed on a vehicle seat, and a belt guide connected with the seat body, the belt guide having a deployed position protruding upward from the seat body and a storage position stowed in a storage cavity in the seat body, the belt-positioning seat being placed in the receiving region of the seat base with the belt guide in the storage position.
