Lockable Wheel Mount for Stroller Maneuverability and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stroller apparatuses face difficulty in maneuverability, especially in limited spaces due to fixed rear wheels, which restricts their ability to turn effectively.
Innovation Solution
A wheeled carrying apparatus with controllably lockable and unlockable wheel assemblies, allowing for flexible orientation of wheel axes, enabling better maneuverability by pivoting the handle frame relative to the standing frame and using a locking assembly and release mechanism to control wheel rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wheel assemblies are made freely rotatable to improve maneuverability, then the ability to turn in limited spaces is improved, but the stability and control during straight movement deteriorates
Solution Approach 1:
The wheel assembly incorporates a locking mechanism that allows dynamic switching between locked and unlocked states. When locked, the wheel maintains fixed orientation for stable straight movement; when unlocked, the wheel can rotate horizontally to enable turning maneuvers in limited spaces.
2Device complexity
If the wheel axis orientation is fixed to simplify the structure, then the device complexity is reduced, but the adaptability to different movement conditions deteriorates
Solution Approach 1:
The wheel assembly is segmented into independent functional components: a wheel mount that can rotate horizontally, a locking mechanism for securing the wheel orientation, and a release mechanism for unlocking. This segmentation allows the wheel to adapt to different movement conditions while maintaining relatively simple individual components.

AI summary
A wheeled carrying apparatus includes a standing frame, a handle frame, a wheel mount, a locking assembly and a release mechanism. The handle frame is rotatable between a first and a second position. The wheel mount carries a wheel and is rotatable relative to the standing frame for changing an orientation of the wheel axis. The locking assembly is configured to rotationally lock the wheel mount with respect to the standing frame, and configured to unlock the wheel mount so that the wheel mount is rotatable relative to the standing frame for changing an orientation of the wheel axis. The release mechanism includes a first portion provided on the standing frame and coupled to the locking mechanism, and a second portion carried with the handle frame, the second portion being movable along with the handle frame toward and away from the first portion during rotation of the handle frame between the first position and the second position.
