Integrated Wheel Brake Linkage for Simultaneous Rear-Wheel Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheeled carrying apparatuses face difficulties in flexible operation due to non-universal rear wheels and lack of orientation mechanisms, leading to inefficient movement and potential wheel rotation during normal forward travel.
Innovation Solution
A brake mechanism with a driving member, brake assembly, and orientation mechanism that allows simultaneous locking or unlocking of rear wheels, enabling universal rotation of front wheels and flexible operation, including lateral movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a brake mechanism locks a single wheel, then the brake mechanism can be simple, but two brake mechanisms are required to brake two rear wheels respectively, increasing device complexity
Solution Approach 1:
The patent combines two separate brake mechanisms into a single integrated brake mechanism that can simultaneously lock both rear wheels. The driving member connects through linking members to actuating members on both sides, merging the braking function into one unified system that operates both wheels together.
Solution Approach 2:
The single driving member serves multiple functions by simultaneously controlling the braking of both rear wheels. The linking members transmit the braking force from the single driving member to both actuating members, making the system universal in its ability to lock both wheels through one operational input.
2Adaptability or versatility
If the rear wheels are not universally rotatable, then the structure is simple, but the wheeled carrying apparatus lacks flexible operation and cannot perform lateral movement
Solution Approach 1:
The wheel mount is designed to be dynamically rotatable relative to the frame, allowing the rear wheels to universally rotate in multiple directions. This dynamic capability enables the wheeled carrying apparatus to perform lateral movement and flexible maneuvers while maintaining a relatively simple structural design.

AI summary
The present disclosure provides a brake mechanism and a wheeled carrying apparatus. The brake mechanism includes a driving member and a brake assembly including a driving pin, a linking member, an actuating member, a thrusting member and a locking member. The driving pin is connected to one end of the linking member, the other end of the linking member is connected to the actuating member, the actuating member is movably provided within a wheel mount of the wheeled carrying apparatus. The thrusting member is movably provided within the actuating member, the actuating member is connected to the locking member, the driving member drives the driving pin of the brake assembly to move, so that the actuating member is driven by the linking member to be movable, and then drives the locking member to be movable so as to lock or unlock the wheel.
