Seat Mis-Rotation Locking Mechanism With Pivoting Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child seats with rotational capabilities face misuse risks, particularly when younger babies are mistakenly placed in a forward-facing position, necessitating a device that prevents mis-rotation while being stable, reliable, easy to operate, and maintaining a neat appearance.
Innovation Solution
A device for preventing mis-rotation comprising a blocking portion, a mount, a stopper pivotally arranged between side walls, and a pushing assembly that pivots the stopper between locking and releasing positions, facilitated by a torsion spring and a sliding driving block connected to a push button, ensuring secure rotation control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device for preventing mis-rotation is added to the seat, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated device: the blocking portion prevents mis-rotation, the mount provides structural support and positioning, the stopper acts as both a locking element and a visual indicator, and the pushing assembly enables user operation. This merging of functions reduces overall device complexity while maintaining safety effectiveness.
Solution Approach 2:
The patent employs a nested structure where the stopper is pivotally arranged within the mount's accommodating space, the pushing assembly is positioned within the same space, and the blocking portion is integrated with the rotating component. This nesting approach minimizes the device's external dimensions and reduces the number of separate components, thereby reducing complexity while ensuring reliable operation.
2Shape
If the internal structure of the device is hidden, then aesthetic appeal is improved, but ease of operation may deteriorate
Solution Approach 1:
The patent uses the push button as an intermediary element that mediates between the user and the internal locking mechanism. The push button provides an intuitive, easy-to-operate interface that is visually accessible, while the internal structure remains hidden. This intermediary approach maintains aesthetic appeal by concealing complex internal components while ensuring ease of operation through a simple external control interface.
3Volume of moving object
If the stopper is pivotally arranged within the accommodating space, then device compactness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent incorporates a torsion spring that provides pre-compliance and cushioning in the pivotal movement of the stopper. This spring mechanism compensates for manufacturing tolerances and ensures reliable engagement between the stopper and blocking portion, reducing the stringency of manufacturing precision requirements while maintaining compact dimensions.
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
The device effectively locks and unlocks the seat's rotational positions, enhancing safety by preventing incorrect use and maintaining a user-friendly operation, while ensuring a hidden internal structure for aesthetic appeal.
Implementation Method 1
a torsion spring sleeved at the pivot shaft, one end of which is fixed to the stopper and the other end of which is fixed to the mount for biasing the stopper to the locking position
Implementation Method 2
a stopper pivotally arranged between the first side wall and the second side wall through a pivot shaft to pivot between a locking position and a releasing position
Implementation Method 3
a pushing assembly arranged on the bottom wall of the mount, the pushing assembly being capable of sliding on the bottom wall under an action of external force, so as to pivot the stopper from the locking position to the releasing position

AI summary
A device for preventing mis-rotation is connected between a first component and a second component that are relatively rotated. The device for preventing mis-rotation includes: a blocking portion fixed on the first component; a mount fixed on the second component, the mount having a bottom wall, a first side wall and a second side wall, and the bottom wall, the first side wall and the second side wall being configured to form an accommodating space; a stopper pivotally arranged between the side walls and at least partially accommodated in the accommodating space to pivot between a locking position in which the stopper is clamped with and stopped at the blocking portion to prevent the first component from rotating relative to the second component in a rotating direction and a releasing position in which the stopper and the blocking portion are released to allow the first component to rotate relative to the second component in the rotating direction; and a pushing assembly arranged on the bottom wall of the mount and at least partially accommodated in the accommodating space, the pushing assembly being capable of sliding on the bottom wall under an action of external force, so as to pivot the stopper from the locking position to the releasing position.
