Child Seat Headrest With Extendible Chin-Support Side Wings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Children seated in vehicle child restraints often experience head movement forward and to the sides while sleeping, which can lead to discomfort and safety concerns.
Innovation Solution
A headrest with extendible chin-support pads mounted on side wings, allowing caregivers to adjust the pads from a retracted to an extended and inclined position using a lever-operated mechanism, providing support and maintaining the head in an upright position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed chin-support pads are provided on side wings, then head support function is improved, but device complexity and adjustability are worsened
Solution Approach 1:
The chin-support pads are designed to be movable rather than fixed, allowing them to transition between retracted and extended positions. This dynamic design enables the headrest to adapt to different child sizes and support requirements while maintaining reliable head support when extended.
Solution Approach 2:
The headrest is divided into separate functional components: side wings, chin-support pads, and pad movers. This segmentation allows each component to perform its specific function independently, with chin-support pads that can be individually adjusted to provide targeted support where needed.
2Adaptability or versatility
If extendible chin-support pads are provided, then adaptability is improved, but device complexity is worsened
Solution Approach 1:
The chin-support pads are designed to be easily extended and retracted by caregivers without requiring complex mechanisms or tools. The pad movers enable simple manual operation, allowing the system to be self-sufficient and easy to adjust as children grow.
Solution Approach 2:
The movable chin-support pads provide dynamic adjustability, allowing caregivers to extend or retract the pads as needed. This dynamic design achieves high adaptability while keeping the mechanism relatively simple through straightforward mechanical movement.
3Reliability
If chin-support pads are extended to support sleeping children, then comfort and safety are improved, but headrest structure complexity is worsened
Solution Approach 1:
The headrest structure is segmented into distinct components: side wings, chin-support pads, and pad movers. This segmentation allows the chin-support pads to be independently adjusted and extended only when needed, providing comfort and safety without requiring the entire headrest structure to be complex.
Solution Approach 2:
The chin-support pads transition between retracted and extended states based on need, allowing the headrest to maintain a relatively simple structure when not in use while providing enhanced support functionality when required.
