Movable Carrier Link Assembly for Stroller Seating Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional double-seat strollers have fixed seating arrangements, limiting user flexibility in positioning the seats and making it difficult to interact with or observe infants, and they are cumbersome to fold and store.
Innovation Solution
A movable carrier with a bottom frame assembly, support members, link assemblies, position mechanisms, and unlock members that allow the seats to be adjusted and easily folded by changing the relative positions of the link members and support members, enabling flexible seating arrangements and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the two seats are fixed in position, then the structural stability is improved, but the adaptability and user flexibility deteriorate
Solution Approach 1:
The patent applies the dynamics principle by making the link assembly movable rather than fixed. The link member can shift position along the support member between a first position (for stable configuration) and a second position (for folded/compact configuration). This allows the stroller to dynamically adapt between different seating arrangements and folded states, resolving the contradiction between structural stability and adaptability.
2Adaptability or versatility
If the support member is long to accommodate position adjustment, then the adaptability is improved, but the folded size and storage convenience deteriorate
Solution Approach 1:
The patent applies the nesting principle by designing the link assembly to fold inward toward the bottom frame assembly. When folded, the link member and support member are positioned within or adjacent to the bottom frame structure, effectively nesting the extended components within the overall stroller footprint. This reduces the folded size while maintaining the full position adjustment range during use.
3Ease of operation
If the folding mechanism requires complex mechanisms, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent applies the self-service principle through the first unlock member that automatically engages with the position mechanism. When the link assembly is moved to a predetermined position, the unlock member automatically locks it in place without requiring additional user actions or complex locking mechanisms. This simplifies the overall folding mechanism while maintaining ease of operation.
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
Enables users to change the seating positions of the carry members to suit their needs and facilitates easy folding and storage, allowing for convenient handling and storage, even by users with limited strength.
Implementation Method 1
When the first unlock member contacts the bottom frame assembly, the first unlock member carries the position mechanism to move to change the position of the first connect member relative to the link member
Implementation Method 2
The first end portion is pivotally connected to the bottom frame assembly
Implementation Method 3
the first connect member is pivotally connected to the link member and connected to the second end portion of the first support member through the link member

AI summary
A movable carrier includes a bottom frame assembly, a first support member, a link assembly, a position mechanism, and a first unlock member. The first support member has a first end portion pivotally connected to the bottom frame assembly. The link assembly includes a link member and a first connect member. The link member is disposed at a second end portion of the first support member. The first connect member is pivotally connected to the link member and connected to the second end portion through the link member. The position mechanism is disposed on the link assembly and corresponds to the first connect member. The first unlock member is disposed on the link assembly and connected to the position mechanism. When the first unlock member contacts the bottom frame assembly, it carries the position mechanism to move to change the position of the first connect member.
