Detachable Child Holding Accessory for Infant Carrier Stroller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant carrier strollers often lack comfortable support for children, especially when seated for extended periods, and may not allow for a position close to the caregiver, which can reduce the comfort and reassurance for the child.
Innovation Solution
An infant carrier apparatus with a detachable child holding accessory that can be installed in either a seating or reclining position, supported by the backrest frame and handle assembly, allowing for adjustable positioning and easy removal for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid seat is used in the infant carrier apparatus, then the structural strength is improved, but the comfort for prolonged seating deteriorates
Solution Approach 1:
The seat is divided into multiple segments including a rigid support frame and a flexible cushioning layer. The rigid frame provides structural strength while the flexible cushioning layer provides comfort for prolonged seating, resolving the contradiction between strength and comfort.
Solution Approach 2:
The seat combines rigid materials (metal or hard plastic frame) with flexible materials (foam or fabric cushions). This composite structure provides both the structural strength needed for safety and the comfort required for prolonged seating.
2Ease of operation
If the backrest is inclined forward to allow rearward-facing seating, then the child can see the caregiver, but the distance between child and caregiver increases
Solution Approach 1:
The child holding accessory extends the seating capability into a new spatial dimension by positioning the child above and behind the caregiver rather than in front. This vertical and rearward positioning allows the child to be close to the caregiver while maintaining visibility, resolving the contradiction between visibility and distance.
3Adaptability or versatility
If a detachable child holding accessory is added to the infant carrier apparatus, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The child holding accessory is designed to perform multiple functions: it can hold the child in various positions (upright, reclined), can be installed on different types of strollers, and can be used with different seat configurations. This multi-functionality justifies the added complexity by providing significant versatility benefits.
Solution Approach 2:
The child holding accessory incorporates adjustable and movable components that allow dynamic reconfiguration. The backrest can be adjusted to different angles, and the accessory can be easily installed or removed, making the system adaptable rather than fixed, which manages the complexity through flexibility.
4Reliability
If the child holding accessory is made permanently installed, then the reliability is improved, but the ease of storage deteriorates
Solution Approach 1:
The child holding accessory is designed as a separable component that can be detached from the main stroller frame. This segmentation allows the accessory to be removed for storage or transport while maintaining structural stability when installed, resolving the contradiction between reliability and storage convenience.

AI summary
An infant carrier apparatus comprises a support frame, a seat assembly and handle assembly respectively connected with the support frame, a backrest frame, and a child holding accessory. The child holding accessory can be detachably installed on the infant carrier apparatus, supported by the backrest frame and the handle assembly. In one embodiment, the child holding accessory includes a support bracket and an enclosure. For installing the child holding accessory, the backrest frame is adjusted to a position inclined forward. The child holding accessory can be then installed between the backrest frame and the handle assembly, wherein the child holding accessory has two opposite end portions respectively connected with the backrest frame and the handle assembly.
