Infant Care Device Detachable Mounting Latch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant stroller assemblies have complex structures that make them difficult to operate and detach the infant seat from the stroller.
Innovation Solution
An infant care device with a detachable mounting system featuring a casing, latch member, driving member, and resilient members that allow for easy mounting and detachment by moving the latch member between locking and unlocking positions using a cam mechanism, facilitated by a compression spring and indicating member for user feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional separable infant stroller assembly is used, then the infant seat can be detached and mounted to different carriers, but the structure becomes complex and operation becomes difficult
Solution Approach 1:
The latch member and driving member are integrated into a unified mechanism where the driving member's cam portion directly actuates the latch member. This merging of components simplifies the overall structure while maintaining the detachable functionality between infant seat and mounting seat.
Solution Approach 2:
The latch member serves multiple functions: it engages with the insertion portion to secure the infant seat, disengages to allow detachment, and its position can be indicated to the user. The driving member with cam portion provides both the actuation force and the mechanical advantage needed for easy operation, making the system universally applicable to different mounting scenarios.
2Adaptability or versatility
If a conventional separable infant stroller assembly is used, then the infant seat can be detached and mounted to different carriers, but operation becomes difficult
Solution Approach 1:
The latch member is designed to be movable relative to the casing, transitioning dynamically between locked and unlocked positions. The driving member with cam portion provides dynamic actuation, allowing the user to easily switch between secured and detached states through simple pushing motion, greatly improving ease of operation.
Solution Approach 2:
The cam portion of the driving member acts as an intermediary mechanism that translates the user's pushing action into effective movement of the latch member. This intermediary provides mechanical advantage and makes the operation intuitive and easy, resolving the difficulty of operating detachable mechanisms.
3Reliability
If the latch member is resiliently biased toward locking position, then relative movement is prevented, but the latch member must be actively moved to unlock
Solution Approach 1:
The first resilient member pre-biases the latch member toward the locking position, ensuring that the infant seat is automatically secured once inserted. This preliminary action provides reliability without requiring continuous user effort, while the driving member with cam portion is designed to easily overcome this bias when unlocking is needed.
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 solution simplifies the operation and structure of the infant care device, enabling easy mounting and detachment with a user-friendly mechanism that provides visual confirmation of the mounting status, enhancing usability.
Implementation Method 1
The first resilient member is connected between the casing and the latch member, and biases resiliently the latch member toward the locking position
Implementation Method 2
The driving member is mounted movably to the casing and has a cam portion. The driving member is able to be pushed to move the cam portion from a release position to a pushing position

AI summary
An infant care device includes a casing, a latch member, a driving member and a first resilient member. The casing has an insertion space permitting an insertion portion of a mounting seat to be inserted thereinto. The latch member is mounted movably to the casing. The first resilient member biases the latch member to engage the insertion portion so as to prevent relative movement between the infant care device and the insertion portion. The driving member is mounted to the casing, and is able to be pushed to move a cam portion thereof to disengage the latch member from the insertion portion against the biasing action of the first resilient member, so as to permit the relative movement between the infant care device and the insertion portion.
