Rotating Bicycle Carrier Restriction Mechanism to Avoid Loading Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle carriers with non-rotatably connected restriction members are inconvenient for loading and unloading bicycles due to interference issues, requiring manual repositioning of these members to avoid contact with the bicycle.
Innovation Solution
A vehicle restriction mechanism featuring a base and stem member with guiding portions that allow the stem member to rotate between a restricted and release position, facilitating easy adjustment and minimizing interference during bicycle loading and unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If restriction members are non-rotatably connected with the supporting arm, then the structure is simple and stable, but the members interfere with the bicycle during loading and unloading
Solution Approach 1:
The restriction member is designed to be rotatable relative to the supporting arm, transitioning from a static non-rotatable connection to a dynamic rotatable connection. This allows the restriction member to rotate away from the bicycle path during loading/unloading operations, eliminating interference while maintaining structural stability when engaged.
2Object-affected harmful factors
If restriction members are moved to a higher position to avoid interference, then interference with bicycle is avoided, but the operation becomes inconvenient
Solution Approach 1:
Instead of permanently repositioning the restriction member to a higher location, the invention enables the restriction member to dynamically rotate away from the interference zone. This maintains the member in its optimal functional position during carrying while automatically clearing the path during loading/unloading, eliminating the need for manual repositioning.
3Ease of operation
If the stem member is rotatable between restricted and release positions, then loading and unloading is facilitated, but the device complexity increases
Solution Approach 1:
The rotatable stem member provides dynamic positioning capability that enables easy loading and unloading operations. The rotation mechanism allows the stem member to move between a restricted position (for secure carrying) and a release position (for loading/unloading), achieving operational convenience through controlled movement.
Solution Approach 2:
The restriction mechanism is divided into separable components: the base and the stem member. This segmentation allows the stem member to be independently rotated and positioned, facilitating easy loading and unloading while keeping the base structure simple and stable.
4Object-affected harmful factors
If the stem member moves axially relative to the base, then interference with bicycle is avoided, but the mechanism complexity increases
Solution Approach 1:
The base and stem member are designed as separate, modular components with simple individual structures. The stem member can be axially moved relative to the base through a straightforward mechanical interface, allowing it to clear the bicycle path without requiring complex mechanisms in either component.

AI summary
A vehicle restriction mechanism and a vehicle carrier including the same are provided, and the vehicle restriction mechanism is configured to be disposed on a supporting arm of the vehicle carrier and includes a base and a stem member. The base includes a sleeve portion, and the sleeve portion defines an axial direction. The stem member is adjustably positioned on the sleeve portion, and the stem member is rotatable between a restricted position and a release position relative to the base about the axial direction. One of the base and the stem member has a first guiding portion, and the other of the base and the stem member has a second guiding portion movably connected with the first guiding portion. Relative to an outermost bottom surface of the base, heights of at least two parts of the first guiding portion are different in the axial direction.
