Rotating Towing Brackets for Vehicle Bumper Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bumper carrier devices for vehicles are difficult to rapidly and easily attach and remove, and fail to provide a stable fixation when in use, affecting appearance and fuel efficiency.
Innovation Solution
A bumper carrier device with a carrier bar, rotatably mounted towing brackets, and a linking unit that uses a gear belt and worm mechanism to facilitate easy attachment and removal, and secure fixation to the vehicle's bumper back beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a carrier is fixed to the vehicle body, then the vehicle can carry objects, but the appearance and fuel efficiency deteriorate when the carrier is not in use
Solution Approach 1:
The carrier is designed to be dynamically attachable and detachable to the vehicle bumper. The towing brackets can be rotated between a horizontal position (when carrying objects) and a vertical position (when not in use), allowing the carrier to adapt its state based on operational needs while maintaining vehicle appearance.
2Ease of operation
If a carrier is designed to be easily removed from the vehicle, then the appearance and fuel efficiency are maintained, but the fixation stability deteriorates
Solution Approach 1:
The carrier is segmented into multiple independent towing brackets (first and second towing brackets) that can be operated separately. Each bracket has its own screw mechanism that can be independently adjusted and locked, allowing one bracket to be secured while the other remains flexible, thus achieving both ease of operation and fixation stability.
Solution Approach 2:
The position and orientation of the towing brackets can be changed by rotating them to different angles. The brackets can be positioned horizontally for carrying objects, vertically for compact storage, or at intermediate angles, providing multiple operational states while maintaining secure fixation through the screw mechanism.
3Reliability
If a carrier uses a complex fixation mechanism, then the fixation stability is improved, but the attachment and removal time increases
Solution Approach 1:
The towing brackets are pre-positioned and oriented toward the vehicle bumper in a ready-to-attach configuration. The screws are pre-aligned with the bumper holes, allowing the carrier to be quickly attached by simply pushing the brackets forward and securing the screws, without requiring complex alignment procedures or multiple adjustment steps.
4Productivity
If a carrier uses simple attachment mechanisms, then the attachment speed is improved, but the fixation stability deteriorates
Solution Approach 1:
The carrier combines multiple simple attachment mechanisms (first towing bracket with screw, second towing bracket with screw) into a unified system. Each bracket independently provides secure fixation through its screw mechanism, and together they provide redundant stability, achieving both rapid attachment and reliable fixation.
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
Enables rapid, easy attachment and removal, as well as stable object loading and unloading, improving user convenience and vehicle appearance and efficiency.
Implementation Method 1
a gear belt that links the two towing brackets to each other
Implementation Method 2
a bracket rotating unit that is mounted to the carrier bar and rotates one of the towing brackets relative to the carrier bar
Implementation Method 3
two towing brackets which are separated from each other, are rotatably mounted to the carrier bar, protrude toward a body of a vehicle, and are provided with screws at leading ends thereof
Implementation Method 4
couple or decouple the one of the towing brackets to or from a bumper back beam of the vehicle in a screwed manner

AI summary
A bumper carrier device for a vehicle may include a carrier bar, two towing brackets, a bracket rotating unit and a linking unit. The carrier bar may extend in a left and right direction. The two towing brackets may be separated from each other, be rotatably mounted to the carrier bar, protrude toward a body of a vehicle and be provided with screws at leading ends. The bracket rotating unit may be mounted to the carrier bar and rotates one of the towing brackets relative to the carrier bar to couple or decouple the one of the towing brackets to or from the vehicle. The linking unit may transmit operational force of the bracket rotating unit to the remaining towing bracket to couple or decouple the remaining towing bracket to or from the vehicle.
