Motor Vehicle Seat Map Pocket with Rigid U-Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming a pocket in a motor vehicle cover element with a foam layer on its rear surface face challenges, particularly in assembling a net or similar material to a rear panel that is not sufficiently rigid, risking damage to the foam layer.
Innovation Solution
The solution involves using elongated rigid U-shaped frames that sandwich the cover element and the net, with removable fastening tabs to secure the pocket, allowing for a flexible and durable assembly that can be easily integrated with the vehicle's frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a net or similar material is assembled directly to the rear panel with foam layer, then the pocket can be formed with flexible material, but the foam layer may be damaged due to insufficient rigidity of the rear panel
Solution Approach 1:
A rigid frame serves as an intermediary structural element between the net material and the foam layer. The frame provides the necessary rigidity to support the net while distributing loads away from the foam layer, preventing damage. The frame acts as a mediator that translates the flexibility requirement into a form that doesn't compromise the foam integrity.
Solution Approach 2:
The pocket structure combines multiple materials with different properties: a rigid frame material (providing structural support), a flexible net material (providing adaptability), and a foam layer (providing cushioning). This composite construction allows each material to perform its optimal function without compromising the others.
2Reliability
If a rigid frame is used to support the pocket, then the foam layer is protected from damage, but the overall structure becomes more complex
Solution Approach 1:
The pocket structure is segmented into distinct functional components: a rigid frame for structural support, a net material for the pocket front, and a foam layer for cushioning. This segmentation allows each component to be optimized independently and simplifies the assembly process, reducing overall complexity despite adding structural elements.
Solution Approach 2:
Rigidity is applied locally only where necessary (in the frame structure) rather than throughout the entire pocket. The foam layer and net material remain flexible where needed. This localized application of rigidity minimizes the complexity increase while providing sufficient protection where required.
3Stability of the object's composition
If the pocket is formed with a complete rigid frame, then structural stability is improved, but manufacturing and installation become more difficult
Solution Approach 1:
The frame design incorporates flexibility in assembly through removable fastening tabs that allow the frame to be dynamically assembled and disassembled. While the frame structure itself is rigid for stability, the connection method is dynamic, enabling easy manufacturing and installation without compromising structural integrity during use.
Solution Approach 2:
The frame is pre-assembled with the net material attached before installation onto the seat. This preliminary preparation simplifies the final installation step and ensures proper alignment. The fastening tabs are pre-positioned to facilitate straightforward attachment to the seat frame.

AI summary
A map pocket for a motor vehicle cover element formed of a stack formed at least of a cover material made of textile, of leather, of skin, or of a synthetic material, and of a foam layer at the rear surface of the covering material, including: a piece defining the apparent surface of the pocket; elongated rigid elements at least partially surrounding said piece and sandwiching the cover element and said piece.
