Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a manual awning is used, then the device is small in size and light in weight, but it is cumbersome to unfold and store
Solution Approach 1:
The awning system uses spring assemblies and folding linkages to automatically unfold and collapse the sunshade cloth without requiring manual rolling or positioning operations. The structure serves itself by using the pulling force on the rod to trigger the unfolding sequence through mechanical linkages.
Solution Approach 2:
The awning employs dynamic folding linkages that transform the static storage state into an extended protective state through mechanical motion. The folding arms and connecting rods create a dynamic structure that can quickly transition between compact and deployed configurations.
2Weight of moving object
If a manual awning is used, then the device is small in size and light in weight, but it requires slow rolling up of sunshade cloth
Solution Approach 1:
The spring assembly automatically winds the sunshade cloth onto the roller as the structure unfolds, eliminating the need for manual rolling operations. The mechanical system performs the winding function itself through the unfolding motion, significantly reducing the time required.
Solution Approach 2:
The spring assembly is pre-loaded and positioned to automatically wind the sunshade cloth as unfolding begins. This preliminary positioning of the winding mechanism ensures that the cloth is rolled up simultaneously with the unfolding process, rather than requiring a separate time-consuming operation.
3Weight of moving object
If a manual awning is used, then the device is small in size and light in weight, but stability and wind resistance are reduced
Solution Approach 1:
The awning structure is divided into multiple folding linkages and support elements that work together to provide stability. The segmented folding arms and connecting rods create a truss-like structure that resists wind forces while maintaining the lightweight characteristic.
Solution Approach 2:
The folding linkage system provides dynamic stability by distributing wind loads across multiple structural elements. The interconnected arms and rods create a rigid framework when deployed that can withstand external forces while remaining lightweight.
4Ease of operation
If weather interference occurs, then the sunshade cloth rises and falls under external force, but it is difficult to complete opening or storage alone
Solution Approach 1:
The folding linkage system automatically responds to external forces by triggering the unfolding or folding sequence. When wind or rain applies force to the sunshade cloth, the mechanical linkages convert this force into the motion needed to secure the awning in its appropriate state without requiring manual intervention.
Solution Approach 2:
The locking mechanism and folding linkage design anticipates external forces and automatically engages stability features. The structure prepares counter-actions in advance by using the applied force itself to trigger the locking or securing mechanism, preventing the sunshade cloth from rising or falling uncontrollably.

AI summary
A vehicle-mounted sunshade device and a support mechanism thereof are provided. The vehicle-mounted sunshade device includes a storage housing, a roller for winding a sunshade cloth, and the support mechanism. The support mechanism supports the sunshade cloth when the sunshade cloth is in an unfolded state. The storage housing defines a limiting opening communicating the cover body with an outside. The support mechanism includes two folding assemblies respectively disposed on two opposite sides of the roller and a support assembly. Each of the folding assemblies includes a first folding arm, a second folding arm, a first rotating assembly, and a second rotating assembly. A pull rod fixedly connected to the support assembly is disposed on one side of the sunshade cloth away from the roller. The support mechanism simplifies unfolding and storage of the vehicle-mounted sunshade device, which is convenient to use and improves user experience.
