Reversible Stroller Handle Locking Mechanism for Faster Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers with reversible handles require a lengthy process for handle reversing operations, making them inconvenient and time-consuming.
Innovation Solution
A stroller with a reversible mechanism featuring a release actuator linked to a sliding sleeve, allowing the reversible member to be easily locked or unlocked at different positions on the stroller frame, enabling quick and convenient handle reversing through the use of a release actuator, driving member, and anchoring portions.

Engineering Contradiction Analysis
1Ease of operation
If a conventional sliding sleeve mechanism is used for handle reversing, then the handle can be reversed, but the operation takes a long time and is inconvenient
Solution Approach 1:
The handle reversing mechanism is segmented into distinct functional components: a release button for actuation, a moving sleeve for displacement, a fixed sleeve for positioning, and locking pieces for securing. This segmentation allows each component to perform its specific function efficiently, reducing overall operation time while maintaining ease of use.
Solution Approach 2:
The locking pieces are pre-positioned within grooves on the stroller frame at predetermined locations. When the moving sleeve is displaced by the release button, the locking pieces automatically engage with corresponding features on the stroller frame, eliminating the need for manual positioning and reducing the time required for handle reversal.
2Ease of operation
If the release actuator is disposed at an easy-to-operate position, then the handle reversing operation becomes more convenient, but the mechanism complexity increases
Solution Approach 1:
The release button is nested within the moving sleeve, which itself is disposed on the handle. This nested arrangement allows the release actuator to be positioned at an easily accessible location on the handle while integrating multiple functions into a compact structure, thereby reducing overall mechanism complexity despite improved operability.
Solution Approach 2:
The moving sleeve acts as an intermediary component between the release button and the locking pieces. When the release button is pressed, it displaces the moving sleeve, which in turn releases the locking pieces from their engaged positions. This intermediary mechanism transmits the user's input efficiently while maintaining a simple overall structure.

AI summary
A stroller (100) includes a stroller frame (20), a reversible member pivoted to the stroller frame (20), and a reversible mechanism (30). The reversible mechanism (30) locks the reversible member at different positions and includes a sliding sleeve (4), a release actuator (1) movably disposed on the reversible member and linked with the sliding sleeve (4), and anchoring portions (5) disposed on at least two different positions. The sliding sleeve (4) movably jackets the reversible member and is selectively engaged with any anchoring portion (5). The sliding sleeve (4) moves together with the release actuator (1) or is directly operated for releasing the anchoring portion (5), so as to make the reversible member rotatable to another position. Since the release actuator (1) is linked with the sliding sleeve (4), the release actuator (1) can be disposed at a position easy to operate, so that the handle reversing operation can be performed conveniently and quickly. Furthermore, the reversible mechanism (30) has a simple structural design.
