Foldable Child Restraint Device for Aircraft Seats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lap belts in aircraft seats are not suitable for toddlers and small children, as they can easily escape, and existing seat safety structures are not easily constructible, storable, or transportable.
Innovation Solution
A child restraint device with a base member and back member that can be folded for transport, featuring securing belts and a restraint harness with adjustable shoulder and lap portions, allowing secure attachment to aircraft seats and easy carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lap belts are used in aircraft seats, then the seat structure remains simple, but toddlers and small children can easily extricate themselves making the restraint ineffective
Solution Approach 1:
The child restraint device is divided into separate components: a base member with a lap belt, a back member with a shoulder belt, and a restraint harness. These segments can be independently assembled and adjusted to provide effective child restraint while maintaining simplicity in each individual component.
Solution Approach 2:
The restraint harness acts as an intermediary between the existing aircraft seat belt and the child, providing additional security points (shoulder and lap portions) that work together with the seat belt to prevent child extrication without requiring modification of the seat belt itself.
2Reliability
If existing seat safety structures are designed to be secure, then they provide adequate restraint, but they cannot be conveniently constructed, stored, and transported
Solution Approach 1:
The back member is designed to be foldably attached to the base member, allowing the restraint device to transition between an extended configuration for use and a folded configuration for storage and transport. This dynamic structure maintains security when deployed while enabling convenient portability.
Solution Approach 2:
The restraint device is segmented into removable components including the base member, back member, and restraint harness, allowing for convenient assembly and disassembly. This segmentation enables the device to be constructed at the seat location and easily stored when not in use.
3Ease of operation
If a foldable back member is used in the child restraint device, then storage and transportation become easier, but the device complexity increases
Solution Approach 1:
The foldable attachment between the back member and base member provides a simple hinge mechanism that enables compact folding for storage while maintaining structural integrity during use. This dynamic joint adds minimal complexity compared to the overall restraint system.
Solution Approach 2:
The foldable back member design merges the functions of structural support and compact storage into a single integrated component, reducing the need for separate storage mechanisms and minimizing overall device complexity.

AI summary
A child restraint device may include, in one embodiment, a base member and a back member. The back member may be foldably attached to the base member such that the base member and the back member may be folded together. The child restraint device may also include at least one back member securing belt and at least one base member securing belt. Moreover, the child restraint device may include a restraint harness disposed between the base member and the back member. The restraint harness may include an adjustable shoulder portion attached to the back member and an adjustable lap portion attached to the base member.
