Problem
Conventional child safety seats with side impact protection mechanisms are complex and difficult to operate, making them inconvenient for deployment and storage.
Innovation Solution
A child safety seat design featuring a buffering part pivotally connected to a mount base with a latching mechanism that allows easy deployment and stowing, utilizing a spring for biasing and a latch that engages with a locking slot for secure positioning, enabling simple operation and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional side impact protection mechanism with a button-operated locking mechanism and spring is used, then the buffering part can be locked in the deployed position, but the construction becomes complex and difficult to operate
Solution Approach 1:
The patent extracts the complex button-operated locking mechanism and spring system from the conventional design, replacing it with a simplified latch member that directly engages with a locking slot on the pivot support portion. This extraction eliminates unnecessary components while maintaining the essential locking function, thereby improving ease of operation without sacrificing locking reliability.
Solution Approach 2:
The latch member is designed to be movable between locked and unlocked states through simple user interaction, and it automatically engages with the locking slot when the buffering part is rotated to the deployed position. The system serves itself by using the rotation motion to trigger the locking action without requiring separate button operations or spring mechanisms, thus simplifying the overall construction and operation.
2Reliability
If a conventional side impact protection mechanism with multiple components is used, then the buffering part can be locked securely, but the device complexity increases
Solution Approach 1:
The patent removes the button-operated locking mechanism and spring components from the conventional design, retaining only the essential latch member and locking slot. This extraction significantly reduces the number of parts and simplifies the mechanism while preserving the core locking security function through the direct engagement of the latch with the locking slot.
Solution Approach 2:
The latch member is integrated with the buffering part structure, and the locking slot is formed on the pivot support portion as a unified system. This merging of components reduces the overall device complexity by eliminating separate locking mechanisms while maintaining secure locking through the coordinated movement of the latch and locking slot during buffering part deployment.

Implementation Method 1
the buffering part being movable between a stowed position where the buffering part is retracted toward the first sidewall and a deployed position where the buffering part protrudes sideways from the first sidewall
Implementation Method 2
the latch being engaged with a locking slot provided on the pivot support portion for locking the buffering part in the deployed position

AI summary
A child safety seat (100) includes a seat shell (102), a buffering part (53), and a latching mechanism including a latch (55) carried with the buffering part (53). The seat shell (102) has two sidewalls (31) respectively provided at a left and a right side of the seat shell (102) for restricting sideways movement of a child sitting on the seat shell (102), the two sidewalls including a first and a second sidewall (31), the first sidewall (31) of the seat shell (102) being fixedly connected with a mount base (51) having a pivot support portion (511). The buffering part (53) is pivotally connected with the pivot support portion (511), and is movable between a stowed position where the buffering part (53) is retracted toward the first sidewall (31) and a deployed position where the buffering part (53) protrudes sideways from the first sidewall (31). The latch (55) is movable between a locking state for locking the buffering part (53) in the deployed position and an unlocking state for unlocking the buffering part (53) so that the buffering part (53) is rotatable relative to the seat shell (102), the latch (55) being engaged with a locking slot (5111) provided on the pivot support portion (511) for locking the buffering part (53) in the deployed position.
