Baby Carriage Handrail Pivot Mechanism With Elastic Auto-Return
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby carriages lack a handrail mechanism that provides both rigidity and mobility, offering a comfortable environment for children and facilitating easy entry and exit.
Innovation Solution
A handrail mechanism featuring a shell, a handrail connecting part, and an elastic member, allowing the handrail to pivot between a bounced up and pressed down position, with the elastic member biasing the handrail connecting part towards the bounced up position and enabling automatic reset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid handrail is used, then the handrail provides strong support and protection, but it lacks mobility and comfort for the child
Solution Approach 1:
The handrail is designed with a pivotal connection that allows it to rotate between a horizontal supporting position and a vertical mobile position. This dynamic structure enables the handrail to adapt its orientation based on the child's needs, providing both strong support when horizontal and mobility when vertical, thus resolving the contradiction between strength and ease of operation.
2Ease of operation
If a soft handrail is used, then the handrail provides mobility and comfort, but it lacks the rigidity and protection needed
Solution Approach 1:
The handrail incorporates a pivotal joint that allows the rigid handrail component to rotate and change orientation. When in the horizontal position, it provides strong support; when rotated to the vertical position, it allows mobility and comfort. This dynamic capability resolves the contradiction between needing rigidity for protection and mobility for comfort.
3Stability of the object's composition
If the handrail is fixed in position, then it provides stable support, but it does not facilitate easy entry and exit for the child
Solution Approach 1:
The handrail is designed with a pivotal connection that allows it to rotate between a horizontal stable position for support and a vertical mobile position for facilitating child entry and exit. The elastic member maintains stability during the horizontal position while enabling smooth transitions to the vertical position when needed, thus resolving the contradiction between stability and ease of operation.
4Ease of operation
If an elastic member is added to enable handrail movement, then the handrail gains mobility, but the device complexity increases
Solution Approach 1:
The elastic member is configured to automatically return the handrail to its horizontal supporting position after it has been rotated to the vertical position. This self-service mechanism eliminates the need for additional actuators or control systems, adding mobility through a simple elastic recovery mechanism while minimizing the increase in 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 mechanism provides a handrail that can be displaced under pressure and automatically returns to an upright position, enhancing comfort and ease of use for children.
Implementation Method 1
an elastic member arranged in the accommodating space of the shell, the elastic member having one end connected to the shell, and the other end connected to the handrail connecting part. Among them, the handrail connecting part is able to be pivoted between a bounced up position and a pressed down position, the free end of the handrail connecting part is away from the shell in the bounced up position and is close the shell in the pressed down position, the elastic member is arranged to bias the handrail connecting part toward the bounced up position
