Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle sunshades face difficulties in automatic retraction and extension, particularly in folding the sunshade fabric at the corners for storage, leading to inconvenient manual manipulation and challenges in integrating automatic controls.
Innovation Solution
A structural skeleton with a base stand, parallel driving axles, gear connectors, turning axles, and lateral-blocking support shafts, allowing for automatic extension and retraction of the sunshade fabric, synchronized movement through cardan joints, and stability features like blocking frames and boards for wind resistance and airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sunshade fabric is attached to movable supporting shafts that can be turned and folded into the frame, then the structure becomes simpler and easier to store, but the sunshade fabric at the four corners cannot be easily folded for storage due to difficulties during the turning and folding of the supporting shafts
Solution Approach 1:
The supporting shafts are divided into multiple segments that can rotate relative to each other. Each segment can be independently folded and stored, allowing the sunshade fabric to be completely folded without manual manipulation. The segmentation enables automatic control mechanisms to operate each segment separately, solving the corner folding difficulty while maintaining structural simplicity.
Solution Approach 2:
The supporting shafts are designed with dynamic rotation capabilities at multiple joints, allowing them to change configuration from extended to folded states. This dynamic design enables the shafts to adapt to different operational requirements and facilitates complete folding of the sunshade fabric for storage, eliminating the need for manual manipulation.
2Device complexity
If manual manipulation is required for folding and storing the sunshade fabric, then the system remains simple in structure, but it becomes inconvenient in practical use and presents difficulties for the addition of automatic controls
Solution Approach 1:
The supporting shafts incorporate dynamic rotation joints that can be actuated by automatic control mechanisms. These joints allow the shafts to move between extended and folded positions under automated control, enabling the system to transition from manual to automatic operation without significant structural complexity.
Solution Approach 2:
The sunshade system is designed with self-folding capabilities through its segmented supporting shafts that can automatically return to the folded position. This self-service mechanism reduces the need for complex automatic control systems while still enabling convenient storage and operation.
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 easy automatic control and convenient use by allowing the sunshade fabric to fold completely, reducing manual effort and enhancing performance by facilitating simultaneous and stable extension and folding processes.
Implementation Method 1
the two ends of the driving axles are mounted with an axial gear attached to the driving axle supporters, around which the driving axles rotate; the lateral-turning axles are connected to a turning gear, which correspondingly engages the axial gear
Implementation Method 2
The driven axles and the driving axles are arranged on the same plane, and the ends of the driven axles and the driving axles are connected with cardan joint

AI summary
A vehicle awning framework comprises a base stand (1), above which a pair of driving axles (2) is parallelly arranged from the front to the rear. A pair of driving axle supports (3) is sleeved on each driving axle(2). Two shaft gears(4) are sleeved respectively at the two ends of said driving axle(2), and respectively fixedly connected with a driving axle supports(3). The two ends of the driving axle (2) are respectively fixedly connected with a gear connection connectors (5) through which a laterally-turning axle (6) rotated around the gear connecting connectors (5) is arranged. The laterally-turning axle (6) rotates around itself when it turns outward, so that laterally-turning shafts (8) on the laterally-turning axle (6) are spread to the left and right sides, and the awning can be closed and folded entirely along with the turning of the laterally-turning shafts (8). Therefore the vehicle awning framework can be operated automatically and easily.
