Child Safety Seat Headrest Lighting With Separated Power Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of child safety seats with illumination devices, where all components including the power supply are on the side wing, increases the weight and risk of components detaching during a car accident, posing a safety hazard and limiting design flexibility.
Innovation Solution
The illumination device is placed on the side wing, while the power supply is separately located on a pivot shaft, reducing the overall weight of the side wing and allowing for adjustable light positioning without increasing the side wing's weight, thus enhancing safety and design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If all components including power supply are disposed on the side wing, then the illumination device can illuminate the child's knee area effectively, but the weight of the side wing increases causing safety hazards during car accidents
Solution Approach 1:
The illumination apparatus is divided into separate components: the illumination device remains on the side wing while the power supply device is relocated to the headrest mechanism body. This segmentation reduces the weight of the side wing, minimizing safety hazards during accidents while maintaining illumination functionality.
Solution Approach 2:
The power supply device, which is the heaviest component of the illumination apparatus, is extracted from the side wing and repositioned to the headrest mechanism body. This extraction directly reduces the side wing's weight and eliminates the safety hazard of heavy components detaching during car accidents.
2Illumination intensity
If all components of the illumination apparatus are disposed on the side wing, then the illumination function is achieved, but the design flexibility of the child safety seat is reduced
Solution Approach 1:
By segmenting the illumination apparatus into the illumination device and power supply device, and placing them in different locations (side wing and headrest body respectively), the design gains flexibility. The illumination device can be positioned to provide effective lighting while the power supply is located independently, allowing for more versatile industrial design configurations.
3Stability of the object's composition
If all components including power supply are disposed on the side wing, then the illumination device can be integrated into the side wing structure, but the components may detach during car accidents endangering the child
Solution Approach 1:
The power supply device is extracted from the side wing structure and relocated to the headrest mechanism body. This extraction eliminates the safety hazard of heavy components detaching during car accidents, as the power supply is now positioned in a more stable location that is less likely to detach or cause injury during impact.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the likelihood of the illumination components detaching during an accident and enhances design flexibility by distributing the power supply away from the side wing, ensuring safer and more versatile child safety seat design.
Implementation Method 1
an illumination device disposed on the side wing; and a power supply device electrically connected to the illumination device and being disposed separating from the side wing, the power supply device used for providing electrical power to drive the illumination device to emit light
