Child Seat Belt Clamp Locking Mechanism Against Accidental Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child safety seat clamping devices are prone to accidental unlocking due to accidental touches, posing a safety risk to children.
Innovation Solution
A safety belt clamping device with a locking mechanism comprising an operating member, driving member, locking member, and elastic member, which ensures the locking member remains in a locked position unless intentionally actuated, preventing accidental unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the unlocking button and locking hook are fixed and directly connected, then the operation is simple and convenient to unlock, but it is easy for a child to wrongly unlock due to accidental touch
Solution Approach 1:
The direct connection between the unlocking button and locking hook is segmented by introducing an intermediate driving member. The unlocking button connects to the driving member, which in turn connects to the locking member, creating a multi-stage transmission mechanism that prevents direct accidental activation while maintaining operational simplicity.
Solution Approach 2:
The driving member acts as an intermediary between the unlocking button and the locking member. This intermediate element requires deliberate multi-step operation to transmit force through the system, preventing accidental unlocking from single-point touches while preserving the ease of intentional unlocking by the adult user.
2Reliability
If a locking mechanism with multiple components is added to prevent accidental unlocking, then the safety is improved, but the device complexity increases
Solution Approach 1:
Multiple functional components are merged into integrated assemblies. The driving member combines button reception, force transmission, and locking control functions. The locking member integrates the locking hook, elastic member attachment, and positioning features, reducing the number of separate parts while maintaining safety functionality.
Solution Approach 2:
The driving member serves multiple functions: receiving the unlocking button input, transmitting force to the locking member, and providing structural support for the locking mechanism. The elastic member simultaneously provides restoring force and maintains constant tendency for the locking member to return to the locked position, reducing the need for separate reset mechanisms.
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 prevents accidental unlocking, ensuring high safety by requiring deliberate action to release the clamping mechanism, thereby enhancing onboard safety for children.
Implementation Method 1
The elastic member is installed at the side of the clamping member, and configured to keep the locking member constantly having a tendency to move from the unlocking position to the locking position
