Convertible Wind Deflector Nested Frame Articulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convertible vehicles face significant mounting effort when displacing wind deflectors between function positions, particularly due to their complex arrangement and need for additional storage space.
Innovation Solution
A wind deflector system with articulately jointed and pivotably displaceable frames that allows for easy transition between stowage and two function positions, integrating seamlessly with the storage space cover, enabling manual or motorized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wind deflector is arranged behind the backseat or between the backseat and the backrest of the front seats, then the wind deflector can be positioned in different function positions, but the displacing between the two function positions involves great mounting effort
Solution Approach 1:
The inner frame is received within the outer frame in the stowage position, creating a nested configuration that reduces mounting effort while maintaining positioning flexibility. The frames articulate relative to each other, allowing easy transition between function positions without complex mounting operations.
Solution Approach 2:
The wind deflector employs two hinge arrangements that enable dynamic articulation between the inner and outer frames. This dynamic mechanism allows the wind deflector to transition smoothly between stowage and function positions, significantly reducing the mounting effort required while preserving adaptability.
2Ease of manufacture
If additional storage space is allocated for the wind deflector, then the wind deflector can be stored, but the vehicle interior space is reduced
Solution Approach 1:
The wind deflector is merged with the storage space cover, which forms part of the vehicle interior. By integrating the wind deflector into the existing storage space cover structure, no additional construction space is required, thus preserving vehicle interior volume while achieving easy storage.
Solution Approach 2:
The storage space cover serves dual functions: it stores the top in the closed position and also stores the wind deflector in the stowage position. This multi-functionality eliminates the need for dedicated wind deflector storage space, maintaining vehicle interior volume while providing comprehensive storage capability.
3Volume of stationary object
If the wind deflector is laid up against the upper side of the storage space cover, then no additional construction space is needed, but the wind deflector structure becomes more complex
Solution Approach 1:
The inner frame is received within the outer frame when the wind deflector is in the stowage position against the storage space cover. This nested configuration allows the complex articulated structure to be compacted into a space-efficient arrangement that integrates with the storage space cover without requiring additional construction space.
Solution Approach 2:
The wind deflector is divided into two separate frames (inner frame and outer frame) that can articulate relative to each other via hinge arrangements. This segmentation allows the structure to achieve the necessary complexity for multi-position functionality while enabling compact storage configuration against the storage space cover.

AI summary
A convertible vehicle having a displaceable top and a top storage space, which can be closed using a storage space cover, as well as a wind deflector, which is displaceable between a retracted stowage position and at least one erected function position and can have an inner frame on which a wind deflector function element is spanned. The wind deflector can have an outer frame, to which the inner frame is pivotably mounted and which is pivotably mounted to the storage space cover.
