Stroller Seat Attachment Mount for One-Handed Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stroller designs lack an efficient mechanism to securely and rotatably attach a dual-purpose car seat to the frame, often allowing play and requiring two-handed operation for securing and releasing.
Innovation Solution
A stroller attachment mechanism featuring a frame-mounted attachment mount and a seat-mounted mating attachment mount with complementary V-shaped components, secured by a locking assembly with spring-loaded latches and a release slide, allowing one-handed operation and preventing rotational play.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple attachment mechanism is used, then the device complexity is reduced, but the reliability of securing the seat to the frame deteriorates
Solution Approach 1:
The attachment mechanism is divided into separate functional components: a latch member with wedge-shaped element for securing, a release member for operation, and complementary V-shaped mounting surfaces for alignment. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity
Solution Approach 2:
The latch member is positioned within the attachment mount, and the release member is integrated into the latch member structure. This nesting arrangement consolidates multiple functions into a compact configuration, reducing overall device complexity while maintaining reliability
2Reliability
If a secure locking mechanism is implemented, then the reliability of seat attachment is improved, but the ease of operation deteriorates due to requiring two-handed operation
Solution Approach 1:
The spring-loaded latch member automatically engages with the attachment mount when the seat is placed on the stroller, securing it without requiring manual intervention for the locking action. The user only needs to press the release member to detach, enabling one-handed operation while maintaining secure attachment
Solution Approach 2:
The spring is pre-loaded to automatically drive the wedge-shaped element into the complementary V-shaped surface, creating the locking action before the user completes the attachment. This preliminary securing action ensures reliability while simplifying the user's task to merely guiding the seat into place
3Stability of the object's composition
If a rotational prevention mechanism is added, then the stability of the seat attachment is improved, but the device complexity increases
Solution Approach 1:
The complementary V-shaped surfaces are designed with asymmetric geometry where the wedge-shaped element of the latch member fits precisely into the V-shaped recess of the attachment mount. This asymmetric configuration naturally prevents rotation by providing a unique geometric interface that only accommodates the correct orientation, eliminating the need for additional anti-rotation components
4Ease of operation
If a one-handed release mechanism is implemented, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The release member is designed as a movable component that, when actuated by a single hand, dynamically shifts the latch member from its engaged position to a disengaged position. This dynamic mechanism allows one-handed operation while integrating smoothly with the existing latch structure, minimizing additional 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 secure, one-handed attachment and release of a dual-purpose car seat to the stroller frame, preventing rotation and ensuring stable, play-free engagement.
Implementation Method 1
The release slide may be configured to be biased by a spring to move the wedge-shaped element of the at least one latch within the recesses of the attachment mount and the mating attachment mount to secure the mating attachment mount to the attachment mount
Implementation Method 2
The hollow body may include a V-shaped outer surface. The mating attachment mount may include an inverted V-shaped body configured to fit over the V-shaped outer surface of the hollow body of the attachment mount
Implementation Method 3
The at least one latch may include a wedge-shaped element that is sized and shaped to fit within the recess of the hollow body of the attachment mount

AI summary
A stroller includes a frame, a seat configured to be releasably secured to the frame, an attachment mount associated with the frame, and a mating attachment mount associated with the seat. The mating attachment mount has a shape configured to conform to a shape of the attachment mount. The stroller further includes a locking assembly configured to releasably secure the mating attachment mount to the attachment mount.
