Vehicle Carrier Frame with Swingable Movable Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle carriers face issues with poor assembling stability, labor-intensive operation, and structural weakness, especially when handling heavy vehicles, due to the lack of a positioning mechanism for the supporting board, leading to potential vehicle displacement and component damage.
Innovation Solution
A vehicle carrier with a hanging assembly and rotatable carrying assembly, featuring a movable rod that allows the frame to switch between a locking and release position, enabling easy operation and storage by preventing swinging when loaded and allowing for safe inclination during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a supporting board is used to connect the vehicle carrier with the ground, then the operation becomes laborsaving, but the assembling stability is poor due to lack of positioning mechanism
Solution Approach 1:
The patent introduces a supporting frame as an intermediary component between the vehicle carrier and the ground. This supporting frame includes a positioning mechanism with positioning protrusions and positioning grooves that ensure stable assembly. The supporting frame acts as a mediator that both reduces operational effort (by providing mechanical support) and ensures assembling stability (through the positioning mechanism), thus resolving the contradiction between ease of operation and assembling stability.
Solution Approach 2:
The patent separates the supporting function from the vehicle carrier body by extracting it into a distinct supporting board and supporting frame assembly. This allows the supporting board to be optimized for load-bearing and the supporting frame to be optimized for positioning and connection, with each component having specialized features (positioning protrusions, positioning grooves, swingable connections) that address both operational ease and assembling stability independently.
2Device complexity
If the supporting board is directly leaned against the vehicle carrier without positioning mechanism, then the structure is simple, but the assembling stability is poor
Solution Approach 1:
The patent segments the connection system into multiple functional components: a supporting board for load-bearing, a supporting frame for positioning, positioning protrusions for alignment, and positioning grooves for engagement. This segmentation allows each component to have a specialized function while working together as an integrated system, achieving high assembling stability without excessive overall complexity.
Solution Approach 2:
The patent applies local quality by adding positioning features (protrusions and grooves) only at specific critical locations where connection and alignment are needed, rather than making the entire structure complex. The positioning mechanism is localized to the interface between the supporting frame and the vehicle carrier, providing stability exactly where required while keeping the rest of the structure relatively simple.
3Ease of operation
If the carrying frame is swingable to load the vehicle, then the operation is easier, but the corner has poor structural strength and components are easily damaged
Solution Approach 1:
The patent implements a dynamic connection system where the supporting frame can swing relative to the vehicle carrier body through a hinge connection. This dynamic feature allows the frame to move during loading operations (improving ease of operation) while the hinge connection and reinforcing corner structures maintain structural strength. The swingable connection is designed to accommodate movement while preventing damage to components.
4Productivity
If the vehicle is pushed onto the corner of the fixed frame, then the vehicle can be loaded, but great exertion is required which may cause the vehicle to displace and fall down
Solution Approach 1:
The patent creates an equipotential loading surface by extending the supporting frame to provide a gradual incline and platform for vehicle loading. Instead of requiring the vehicle to be pushed directly onto a high corner (which requires great exertion), the supporting frame creates a series of intermediate levels that reduce the force needed at any single point, allowing smoother and safer vehicle loading.
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
The solution enhances operational ease, stability, and durability by ensuring the vehicle can be easily loaded and unloaded without excessive exertion, while maintaining structural integrity and preventing component damage.
Implementation Method 1
The movable rod is movable in a longitudinal direction of the frame to drive the second engaging portion to move relative to the first engaging portion between a locking position and a release position
Implementation Method 2
When the movable rod is axially moved relative to the frame and drives the second engaging portion to move to the release position, the frame is swingable relative to the hanging assembly to an inclined position

AI summary
A vehicle carrier is provided, including: a hanging assembly and at least one carrying assembly. The hanging assembly includes a first engaging portion. The at least one carrying assembly is rotatably and transversely disposed on the hanging assembly and includes a frame configured for a vehicle to be disposed thereon, a movable rod and a second engaging portion connected with the movable rod. The movable rod is movable in a longitudinal direction of the frame to drive the second engaging portion to move relative to the first engaging portion between a locking position and a release position. When the movable rod is axially moved relative to the frame and drives the second engaging portion to move from the locking position to the release position, the frame is swingable relative to the hanging assembly between a carrying position and an inclined position.
