Foldable Infant Carrier Seat Frame for Dual Seating Orientations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional infant carriers, such as strollers, often lack multiple seating positions, preventing interaction between the child and parent, and require more space for assembly, which can lead to storage issues and accidental misuse of seating configurations.
Innovation Solution
An infant carrier apparatus with a support frame, seat assembly, and backrest assembly that allows the second seat frame to rotate between unfolded and folded positions, preventing erroneous use by locking the rear-facing configuration when not intended, and enabling easy adjustment between forward and rearward seating orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stroller is provided with front and rear seats to allow multiple seating configurations, then the child can face either forward or rearward, but the stroller requires a larger space for assembling the front and rear seats, which is detrimental to storage
Solution Approach 1:
The stroller seat is divided into two separate seat frames (first seat frame and second seat frame) that can be independently positioned. The second seat frame can be folded to a disabled position adjacent to the backrest, allowing the stroller to occupy less storage space while still providing multiple seating configuration options when needed.
Solution Approach 2:
The second seat frame is designed to be dynamically adjustable between an unfolded operational position and a folded disabled position. This dynamic configuration allows the stroller to adapt its space requirement based on whether multiple seating options are needed, optimizing both versatility and storage efficiency.
2Adaptability or versatility
If a stroller is provided with front and rear seats for multiple seating configurations, then the child can be seated in different orientations, but the adult may erroneously seat the child on the rear seat facing rearward while the stroller is actually configured for seating the child facing forward
Solution Approach 1:
Before enabling rear-facing seating, the user must first unfold the second seat frame from its disabled position. This preliminary action ensures that the rear-facing seating configuration is intentionally activated, preventing erroneous seating. The system requires deliberate user action to change the seating configuration state.
Solution Approach 2:
The second seat frame acts as an intermediary element that mediates between the forward-facing and rear-facing seating configurations. When folded, it disables the rear-facing option; when unfolded, it enables it. This intermediary mechanism provides clear visual and physical indication of the current seating configuration state.
3Adaptability or versatility
If the second seat frame is kept in an unfolded position to provide rear-facing seating option, then multiple seating configurations are available, but the apparatus occupies more space and may be misused
Solution Approach 1:
The second seat frame is extracted from the permanent structure and made independently foldable. When not needed, it can be folded to a disabled position adjacent to the backrest, removing the potential for erroneous use and reducing the space occupied by the stroller, while still allowing access to rear-facing seating when required.

AI summary
An infant carrier apparatus having multiple seating positions comprises a support frame, a seat assembly connected with the support frame, and a backrest assembly including a backrest frame. The seat assembly includes a first seat frame and a second seat frame, and the second seat frame is operable to rotate relative to the first seat frame between an unfolded position and a folded position. The backrest frame is operable to rotate about a pivot axle relative to the support frame, wherein the folded position of the second seat frame is substantially parallel and adjacent to the backrest frame. Because the second seat frame can be conveniently folded to a disabled state adjacent to the backrest frame, erroneous use of the second seat frame can be prevented.
