Movable Seat Support for Child Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger transport carriers lack versatility and flexibility in accommodating different modes of transportation, such as bicycle, ski, walking, hiking, and jogging, and do not provide adequate support and protection for passengers in various positions.
Innovation Solution
A passenger transport carrier with a frame assembly that includes upper and lower frames, seat supports, and locks, allowing the seat to move between upright and reclined positions, and featuring a multi-function design that can be used in multiple modes of operation, with adjustable seat positions and a secure locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the seat support is made movable to allow adjustment between upright and reclined positions, then the adaptability and versatility of the carrier is improved, but the device complexity increases due to the need for locking mechanisms and guide channels
Solution Approach 1:
The seat support is designed as a movable component that can dynamically change position between upright and reclined configurations. The elongate member slides within the guide channel, allowing the seat support to move from a first position to a second position, providing adaptability while maintaining structural integrity through the defined movement path.
Solution Approach 2:
The locking mechanism acts as an intermediary component that mediates between the movable seat support and the fixed frame structure. The lock engages with the elongate member at specific positions to secure the seat support, enabling position changes while preventing unintended movement during operation.
2Reliability
If multiple locks are used to secure the seat support at different positions, then the reliability and safety of the carrier is improved, but the device complexity and number of components increases
Solution Approach 1:
The locking mechanism is designed with localized engagement features where the lock interacts with specific portions of the elongate member at defined positions. The guide channel contains localized engagement zones that correspond to predetermined seat positions, allowing the lock to secure the seat support at specific locations while maintaining simplicity elsewhere in the structure.
3Adaptability or versatility
If the upper seat support is designed to move independently from other seat supports, then the adaptability for different passenger configurations is improved, but the device complexity and structural requirements increase
Solution Approach 1:
The carrier is divided into separate modular components, with each upper seat support being an independent module that can move autonomously. Each seat support has its own elongate member and guide channel arrangement, allowing independent adjustment without affecting other seat supports, thereby enabling flexible passenger configurations while maintaining manageable structural complexity.

AI summary
A child transport carrier includes a lower frame, an upper frame, a rear frame, and a first upper seat support. The lower frame includes a first end and a second end. The upper frame includes a first end and a second end. The rear frame extends from the second end of the lower frame to the second end of the upper frame. The first upper seat support includes a cross-member extending transversely across the first upper seat support and having a first end and a second end. The cross-member is configured to move the first upper seat support between a first seat position and a second seat position. The upper frame extends from an upper end of the rear frame and the lower frame extends from a lower end of the rear frame.
