Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle seat structures require high manufacturing effort and costs due to the need for customization to accommodate various additional components, and they must withstand increased forces during emergencies without compromising stability.
Innovation Solution
A seat structure with a cross member and carrier assemblies that include carrier and bracket elements, allowing for flexible and modular attachment of additional components, enhancing stability and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specially suitable seat structure is manufactured for each additional component, then the attachment reliability is improved, but the manufacturing effort and costs increase
Solution Approach 1:
The patent implements a universal carrier assembly design that can accommodate multiple different additional components (fire extinguisher, calf support, ISOFIX child seat anchorages) without requiring custom seat structure manufacturing. The carrier assembly serves multiple functions and can be adapted to different components through simple attachment variations, resolving the contradiction between attachment reliability and manufacturing effort
2Stability of the object's composition
If the seat structure is designed to withstand increased forces from multiple additional components, then the stability is improved, but the device complexity increases
Solution Approach 1:
The patent segments the seat structure into modular components: a basic seat structure and separate carrier assemblies. Each carrier assembly is an independent module that can be attached to the cross member, allowing the seat structure to handle multiple components without requiring a completely redesigned complex structure. The carrier elements and bracket elements are further segmented to provide attachment points while maintaining structural simplicity
Solution Approach 2:
The carrier assembly merges multiple functions into a single structural unit that attaches to the cross member and provides mounting capability for various additional components. This consolidation allows the seat structure to maintain stability while avoiding the complexity of designing separate attachment mechanisms for each component type
3Adaptability or versatility
If the seat structure is customized for specific additional components, then the adaptability is improved, but the productivity decreases
Solution Approach 1:
The universal carrier assembly design enables high adaptability to different additional components while maintaining standardized manufacturing processes. The same carrier assembly can accommodate fire extinguishers, calf supports, ISOFIX child seat anchorages, or other components without requiring custom manufacturing, thus preserving manufacturing productivity
Solution Approach 2:
The carrier assemblies are pre-manufactured as standardized components with built-in attachment capabilities. This preliminary preparation allows for quick assembly with different additional components without requiring custom manufacturing or complex adaptation work, thereby maintaining high manufacturing productivity while achieving component versatility

AI summary
A seat structure for a motor vehicle seat may include a cross member positioned close to a front edge of a seating area of the motor vehicle, a first side part connected to a first end region of the cross member and a second side part connected to a second end region of the cross member. The seat structure may further include a first and second carrier assembly. The first and second carrier assemblies may each include a carrier element with a fastening section for fastening at least one component and a bracket element fastened to the carrier element while receiving the cross member, at least in sections, between the carrier element and the bracket element. The carrier element of the first carrier assembly can be attached to the first side part and the carrier element of the second carrier assembly can be attached to the second side part.
