Child Safety Seat Assembly With Backrest-Linked Position Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seats face challenges in ensuring comfortable seating for children without a backrest, as the seat part can be randomly adjusted, occupying excessive vehicle space, and traditional storage cups are inconvenient and pose safety hazards.
Innovation Solution
A child safety seat with a seating assembly that allows the backrest to be detached only when the seating body is in a preset position, featuring a locking mechanism to prevent misalignment and a folding mechanism for easy storage, along with a storage device that can be adjusted and securely attached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the backrest is made detachable to reduce space occupation, then the vehicle space usage is improved, but the risk of misalignment and uncomfortable seating increases
Solution Approach 1:
The patent applies preliminary action by providing preset positioning structures (positioning grooves and positioning protrusions) that pre-establish the correct alignment position before the backrest is detached or installed. This ensures that when users detach or reinstall the backrest, it automatically returns to the predetermined comfortable seating position, preventing misalignment while maintaining the space-saving detachable feature
Solution Approach 2:
The patent uses positioning grooves and positioning protrusions as intermediary elements between the backrest and the seat body. These intermediaries guide the backrest into the correct position during installation and detachment, ensuring reliable alignment while allowing the backrest to be freely detached for space reduction
2Ease of operation
If the seat part can be randomly adjusted to improve comfort, then the seating comfort is improved, but the space occupation and misalignment risks increase
Solution Approach 1:
The patent applies dynamics by making the backrest adjustable between different states (attached and detached) while maintaining dynamic positioning capabilities when attached. The positioning structures allow the backrest to be dynamically adjusted to preset positions, providing comfort variations without random adjustment, thereby reducing space occupation when detached
3Device complexity
If traditional storage cups are used to simplify structure, then the device complexity is reduced, but safety hazards and inconvenience increase
Solution Approach 1:
The patent applies universality by designing the storage cup as a multi-functional component that not only stores items but also serves as a safety element. The storage cup is integrated with the seat structure and positioned to prevent children from accessing dangerous areas, thereby eliminating safety hazards while maintaining simple structure
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
Ensures comfortable seating for children by preventing misalignment of the seat part, reduces vehicle space occupation, and enhances safety by securing the storage device, making the seat more convenient to use and store.
Implementation Method 1
a movable element located between the backrest and the seating body, wherein when the backrest is detached with respect to the seating body, the movable element is disengaged from the backrest and locked with the base
Implementation Method 2
when the backrest is detached with respect to the seating body, the movable element is disengaged from the backrest and locked with the base to lock movement of the seating body with respect to the base
