Adjustable Body Frame for Moving Carrier Straight Trajectory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moving carriers, such as golf carts and strollers, often deviate from a straight path due to manufacturing or usage issues, causing inconvenience to users.
Innovation Solution
A moving carrier design that includes an adjustment assembly allowing the relative positions of the body frame and body frame connecting device to be adjusted, enabling the angle between the axle frame and body frame to be calibrated, thereby maintaining a straight trajectory without altering the axle or wheel positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the moving carrier uses a fixed body frame and axle frame configuration, then the structure is simple and easy to manufacture, but the carrier cannot go straight due to manufacturing or usage deviations
Solution Approach 1:
The patent applies the dynamics principle by making the body frame adjustable relative to the body frame connecting device through the adjustment assembly. This allows the frame structure to change from a fixed state to an adjustable state, enabling correction of directional deviations while maintaining structural simplicity. The adjustment mechanism permits dynamic repositioning of the body frame to achieve straight movement without complicating the overall device structure.
2Manufacturing precision
If the axle or wheel positions are adjusted to correct directional deviation, then the carrier can go straight, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the adjustment function from the axle and wheel components and relocates it to the body frame and body frame connecting device. By removing the adjustment requirement from the wheel assembly and placing it at the body frame level, the patent simplifies the adjustment process. Users can correct directional deviations by adjusting the body frame position rather than disassembling and repositioning wheels or axles, significantly improving ease of operation.
3Strength
If the body frame and body frame connecting device are rigidly fixed together, then the structure is stable and strong, but the carrier cannot be adjusted to move straight
Solution Approach 1:
The patent transforms the rigid fixed connection between the body frame and body frame connecting device into a dynamic adjustable connection through the adjustment assembly. This allows the connection to maintain structural strength in its fixed state while providing adaptability when adjustment is needed. The body frame can be repositioned relative to the body frame connecting device to correct directional deviations, then securely fixed in the new position, combining both strength and adaptability.
