Infant Seat Accessory Sliding Lock to Prevent Wrong Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant seat safety accessories, such as front protection bodies, are prone to incorrect detachment due to user error, posing a safety risk as they are easily detached from the infant seat, which can lead to unsafe conditions during car movements.
Innovation Solution
An accessory with a sliding operating member that switches the engaging portion between locking and releasing positions, featuring an engaging hook, elastic members, and a secondary security lock, allowing for secure engagement and disengagement from the infant seat with reduced manufacturing costs and improved operational convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operating member is designed for direct detachment of the front protection body, then the operational convenience is improved, but the reliability deteriorates due to easy wrong operation
Solution Approach 1:
The operating member is divided into two distinct parts: a first operating part for locking and a second operating part for releasing. This segmentation ensures that different operations require different actions, preventing accidental or wrong operations while maintaining ease of use for the intended functions.
Solution Approach 2:
The operating member transitions from a static direct-detachment design to a dynamic two-stage mechanism. The member can be operated in two different ways (first operating part for locking, second operating part for releasing), creating a more reliable system that prevents wrong operations while maintaining convenience.
2Reliability
If a complex locking mechanism is adopted to prevent wrong operation, then the reliability is improved, but the device complexity increases
Solution Approach 1:
Rather than creating a complex multi-component locking system, the patent segments the operating member into two functional parts. This simple segmentation achieves reliability by preventing wrong operations without introducing additional complex mechanisms, thereby maintaining low device complexity.
Solution Approach 2:
The operating member serves multiple functions through its two operating parts: the first part performs locking function while the second part performs releasing function. This multi-functionality within a single component achieves reliability without increasing overall device complexity.
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 accessory ensures secure attachment and detachment of the front protection body to the infant seat, enhancing safety by preventing accidental detachment and maintaining a low manufacturing cost through a simple and convenient operation mechanism.
Implementation Method 1
the engaging portion further includes a first elastic member for returning the engaging hook to its original position
Implementation Method 2
the accessory further includes a second elastic member for returning the operating member to its original position

AI summary
The present invention discloses an accessory and an infant seat having the accessory. The accessory includes a main body, an engaging portion and an operating member. The engaging portion is disposed on the main body and has a locking position for engaging with the infant seat and a releasing position for disengaging from the infant seat. The operating member is slidably disposed on the main body and is connected to the engaging portion. The operating member is operated to slide for switching the engaging portion between the locking position and the releasing position. The accessory moves the engaging portion to the locking or releasing position via sliding of the operating member, so that the accessory can be engaged with or detached from the infant seat. The accessory is convenient to operate and has a simple structure and a low manufacturing cost.
