Rotating Cart Bracket With Locking Door Plate for Vibration Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle transport cart brackets require manual lifting and securing with chains, and are prone to cart displacement due to vibration during transport.
Innovation Solution
A bracket design with a cart support unit, door plate unit, rotation support unit, and lock unit that allows efficient loading, securing, and unloading of vehicle transport carts by enabling rotation restriction and release, eliminating the need for manual lifting and chain locks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional U-shaped bracket is used to carry vehicle transport carts, then the bracket structure is simple, but the operator needs to lift the cart higher than the opening and secure it with chain locks, reducing efficiency
Solution Approach 1:
The door plate unit is designed to rotate between an open position (for loading/unloading) and a closed position (for securing), transforming the static bracket into a dynamic system that adapts its configuration based on operational needs. The rotation support unit enables smooth transition between states, improving both efficiency and ease of operation.
Solution Approach 2:
The locking function is merged into the door plate unit itself, which serves both as a closure element and a securing mechanism. When closed, the door plate unit restricts rotation and secures the cart without requiring separate chain locks, combining multiple functions into a single integrated component.
2Reliability
If a conventional open-top bracket is used, then the bracket structure is simple, but the vehicle transport cart can come off the bracket due to vibration during transport
Solution Approach 1:
The door plate unit transitions from an open to closed position during transport, dynamically changing the bracket's configuration from open to enclosed. This dynamic closure prevents cart displacement due to vibration while maintaining structural simplicity through the rotation mechanism rather than adding complex locking components.
Solution Approach 2:
The bracket is segmented into a fixed support plate unit and a rotatable door plate unit, allowing the door plate to move independently to provide securing function. This segmentation enables the securing function to be added without complicating the overall structure, as each segment has a specific function.
3Ease of operation
If chain locks are used to secure the cart and bracket together, then the cart is securely fastened, but the locking and unlocking actions increase operational time and complexity
Solution Approach 1:
The closing action of the door plate unit simultaneously achieves both closure and locking functions. The door plate unit's closed position inherently restricts rotation and secures the cart, merging the securing function into the closure action itself. This eliminates the need for separate locking operations, reducing both time and complexity.
Solution Approach 2:
The door plate unit automatically provides the securing function when closed, without requiring additional manual intervention for locking. The structure itself performs the securing action through its geometric configuration and rotation restriction, making the system self-securing rather than requiring external locking mechanisms.

AI summary
A bracket to load, secure, and unload a cart efficiently, includes a cart support unit configured to support a wheel support member using a support plate open on upper and front; a door plate unit configured to secure the outer periphery of the wheel support member supported on the support plate; a rotation support unit configured to support the door plate unit rotatably; and a lock unit configured to restrict rotation of the door plate unit when the door plate unit is closed to the support plate and permit rotation when the restriction is released.
