Rotary Stroller Accessory Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stroller apparatuses with adjustable handles lack a convenient and secure mechanism for adjusting and locking accessory trays, such as bottle holders, as they fail to provide easy operation and secure positioning changes with handle orientation.
Innovation Solution
A rotary accessory support device is pivotally coupled with the stroller handle, featuring a coupling fixture with latching openings and a detent mechanism in the rotary socket, allowing the accessory support frame to rotate and lock at various angular positions relative to the handle, ensuring secure and adjustable placement of accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the handle orientation is changed, then the tray position must be adjusted to permit proper use, but the conventional construction does not allow convenient operation of the tray and fails to securely lock the position of the tray
Solution Approach 1:
The tray is designed to be rotatable relative to the handle, transforming from a fixed position to a dynamically adjustable position. The rotary socket allows the tray to rotate to different angular positions, enabling users to conveniently adjust the tray orientation according to handle position changes, thus resolving the contradiction between adaptability and ease of operation
Solution Approach 2:
The detent mechanism automatically engages with latching openings at specific angular positions during rotation, providing self-locking functionality. This eliminates the need for separate locking operations, allowing users to simply rotate the tray to the desired position where it automatically locks, thereby improving ease of operation while maintaining adaptability
2Adaptability or versatility
If the tray is made adjustable to different positions, then adaptability is improved, but the mechanism becomes more complex
Solution Approach 1:
The locking mechanism is segmented into discrete latching openings positioned at specific angular intervals around the rotary socket. This segmentation allows the tray to be locked at predetermined positions without requiring a continuous complex locking system, reducing overall mechanism complexity while maintaining adjustability
Solution Approach 2:
The detent acts as an intermediary element between the rotary socket and the latching openings. It simplifies the locking action by using a simple spring-loaded engagement mechanism that automatically locks the tray at designated positions, avoiding the need for complex multi-component locking systems

AI summary
An accessory support device for a stroller apparatus comprises a coupling fixture securely mounted on a handle of a stroller and including a plurality of latching openings, a rotary socket pivotally assembled with the coupling fixture and including a detent and a connecting portion, and an accessory support frame detachably fastened with the connecting portion of the rotary socket. The accessory support frame is operable to rotate with the rotary socket relative to the coupling fixture, and the detent is movable to engage with any one of the latching openings for locking the accessory support frame at different angular positions relative to the coupling fixture.
