Infant carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant transport systems, such as car seats and carriers, are heavy, bulky, and require caregivers to constantly switch between carrying the infant and using their arms for daily activities, limiting mobility and convenience, especially for new mothers who need to avoid heavy lifting.
Innovation Solution
A safety seat system comprising a safety seat liner designed to support a child in a car seat and a harness for adult wearers, with multiple opposite end fasteners for reversible attachment, allowing seamless transition from a car seat to a carrier without disturbing the child, enabling free arm movement for caregivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a contoured shell with carrying handle is used to combine car seat and carrier functions, then the device can accommodate the child in both car and hand transport, but the shell becomes heavy and bulky making it difficult to carry
Solution Approach 1:
The invention divides the car seat system into two separate components: a lightweight liner that fits inside the car seat and a carrier harness that attaches to the liner. This segmentation allows the liner to remain light while the harness provides the carrying function, resolving the contradiction between versatility and weight.
Solution Approach 2:
The liner is designed to serve multiple functions: it provides the seating surface in the car seat and simultaneously serves as the attachment base for the carrier harness. This multi-functionality eliminates the need for a separate heavy shell to provide both car seat and carrier capabilities.
2Reliability
If a heavy shell is used to support the child, then the child can be securely transported, but the caregiver's ability to perform routine activities involving arm movement is limited
Solution Approach 1:
By separating the support function (provided by the car seat base) from the carrying function (provided by the harness), the system maintains child support stability while significantly reducing the weight the caregiver must carry, thereby improving ease of operation.
Solution Approach 2:
The invention extracts the essential carrying function from the heavy shell and relocates it to the lightweight harness system, allowing the caregiver to carry the child securely while maintaining mobility for routine activities.
3Ease of manufacture
If the child must be removed from the car seat and placed into a separate carrier, then each device can be optimized for its specific function, but the process requires constant switching and additional time
Solution Approach 1:
The invention merges the car seat liner and carrier harness into a single integrated system where the liner remains in the car seat and the harness attaches directly to it. This combination allows the child to remain in the same seating position while transitioning from car to carrier mode, eliminating the time-consuming removal and repositioning process.
Solution Approach 2:
The liner is pre-positioned in the car seat and the harness is designed to attach directly to it, so that when transport mode needs to change, the caregiver only needs to attach or detach the harness rather than completely repositioning the child. This preliminary setup minimizes the time and effort required for switching between transport modes.
