Load-Assisting Cargo Bracket with Retractable Assisting Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cargo loading frames for vehicles are unsafe during the loading of large-sized items like kayaks, as they lack protection against unbalanced cargo falling and impacting the vehicle, especially when transitioning from an extension to the main frame.
Innovation Solution
A load-assisting cargo bracket with an assisting assembly that extends and locks away from the vehicle, providing a safe distance and a closed void for temporary accommodation of cargo parts, preventing accidental impacts by ensuring stable positioning and alignment with the vehicle's rail frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an extension is added to the frame to provide a safe distance for lifting cargo, then loading safety is improved, but the device complexity increases
Solution Approach 1:
The assisting assembly is nested within the main body of the cargo bracket. When not in use, the assisting assembly retracts into the main body, maintaining a compact structure. When needed, it extends outward to provide the safe distance for cargo loading, thus providing safety functionality without permanently increasing device complexity.
Solution Approach 2:
The assisting assembly is designed to be movable relative to the main body, transitioning between extended and retracted positions. This dynamic configuration allows the frame to adapt its structure based on loading requirements, providing safety when needed while maintaining simplicity during normal operation.
2Volume of moving object
If the frame size is increased to accommodate large cargo, then cargo capacity is improved, but driving safety deteriorates due to oversized frame
Solution Approach 1:
The cargo bracket system is divided into two segments: the main body that remains compact for driving safety, and the assisting assembly that extends only when needed for cargo loading. This segmentation allows the system to provide large cargo capacity during loading while maintaining a compact profile during normal driving conditions.
Solution Approach 2:
The frame structure transitions from a compact configuration during driving to an extended configuration during cargo loading. The assisting assembly extends only when cargo loading is required, providing the necessary volume for large cargo while minimizing the frame size during normal operation to maintain driving safety.
3Adaptability or versatility
If the assisting assembly is made movable to extend and retract, then loading flexibility is improved, but the reliability of cargo positioning deteriorates
Solution Approach 1:
The assisting assembly is extended in advance before cargo loading begins, providing a stable, predetermined platform for lifting and positioning cargo. This preliminary extension ensures that the cargo loading surface is ready and stable before the cargo is placed, maintaining positioning reliability despite the movable nature of the assembly.
Solution Approach 2:
The assisting assembly acts as an intermediary structure between the operator and the main cargo bracket. It provides a stable intermediate platform for cargo manipulation, transferring the cargo from the ground to the main bracket in a controlled manner, thus ensuring reliable cargo positioning throughout the loading process.

AI summary
A load-assisting cargo bracket for vehicles comprises a main body and an assisting assembly. The main body comprises a bottom, a side rail frame disposed around the bottom, and an accommodating space defined beside the bottom. The assisting assembly comprises a first rod and two second rods. One end of each of the two second rods is connected with the first rod, and the other end of the each second rod is received within a corresponding branch rail of the side rail frame. The each second rod is aligned with the corresponding branch rail of the side rail frame. The first rod is spaced from a back and a top of a vehicle when the two second rods extend out of the side rail frame, and is positioned next to the bottom of the main body when the each second rod is entirely received within the side rail frame.
