Modular Stroller Seat Attachment for Reversible Double Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parents face inconvenience in transporting multiple children due to the size and maneuverability issues of double strollers, and the need for multiple strollers when only one child is present, as existing solutions either compromise comfort or storage capacity.
Innovation Solution
A seat attachment for strollers that can convert a single stroller into a double stroller, featuring a connector portion and seat support element, with optional wheels and a folding mechanism for secure and reversible attachment, allowing the second seat to be positioned forward or backward, and a locking mechanism for easy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a double stroller is used to transport two children, then the capacity to accommodate multiple children is improved, but the size and maneuverability deteriorate
Solution Approach 1:
The stroller system is divided into separate modular components: a base stroller unit and an attachable second seat attachment. This segmentation allows the parent to use only the necessary portion (single or double configuration) rather than always managing a full double stroller, improving maneuverability while maintaining capacity when needed.
Solution Approach 2:
The second seat attachment incorporates a folding mechanism with movable parts that allow the attachment to transition between an extended operational position and a folded compact position. This dynamic capability enables easy storage and transport while maintaining full functionality during use.
2Adaptability or versatility
If a double stroller is used to accommodate two children, then the transportation capacity is improved, but the storage capacity deteriorates
Solution Approach 1:
By separating the second seat into an attachable module rather than integrating it permanently into the stroller frame, the design preserves under-seat storage space in the base unit. The segmented approach allows the storage compartment to remain accessible and uncrowded while still providing the option to add a second seat when needed.
3Adaptability or versatility
If multiple strollers are purchased to accommodate different situations, then the adaptability to different needs is improved, but the storage and portability deteriorate
Solution Approach 1:
The second seat attachment is designed as a universal module that can be attached to various stroller types, allowing a single base stroller to serve multiple functions (single or double configuration). This multi-functionality eliminates the need to maintain separate strollers for different situations, improving portability while maintaining adaptability.
Solution Approach 2:
The folding mechanism enables the attachment to be compacted into a space-efficient form that can be easily stored in a vehicle trunk or carried, eliminating the need for separate storage space for multiple strollers while maintaining the capability to accommodate different situations.
4Adaptability or versatility
If a second seat attachment is added to a single stroller, then the capacity to transport two children is improved, but the comfort and convenience deteriorate
Solution Approach 1:
The attachment is designed as a separate module that connects to the stroller frame without interfering with the primary seat's comfort features or the parent's control. This segmentation ensures that adding capacity does not compromise the ergonomics or ease of operation of the base stroller.
