Vehicle Seat Element With Detachable Fastening for Modular Attachments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seat elements for vehicle seats lack ease of component exchangeability and flexibility in adding attachment units, such as lumbar supports or seat side supports, without the need for complex fastening systems.
Innovation Solution
A seat element comprising two molded bodies arranged in a contact-fitting manner, with separate fastening elements like wires and clips that can be mechanically and detachably joined to the molded bodies, allowing for easy exchange and addition of attachment parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If clips are incorporated in the foam part by foaming to fasten the seat cover, then the fastening is integrated into the structure, but the exchangeability and replaceability of components is lost
Solution Approach 1:
The seat element is divided into separate components: molded bodies and separate fastening elements. The fastening elements are not integrated into the foam structure but are instead separate components that can be independently removed and replaced, enabling component exchangeability while maintaining structural integrity.
Solution Approach 2:
The fastening elements are extracted from the foam structure and made as separate, removable components. This allows the fastening system to be independent of the foam part, enabling replacement of attachment parts without replacing the entire seat element or foam structure.
2Adaptability or versatility
If separate fastening elements are used that can be detachably joined, then component exchangeability is improved, but the structural integration and stability is reduced
Solution Approach 1:
The separate fastening elements are combined with the molded bodies through mechanical connection. The fastening elements are designed to engage with the molded bodies in a way that provides stable structural integration while maintaining the ability to be detached and reattached, balancing both stability and exchangeability.
3Stability of the object's composition
If attachment parts are permanently fastened to the seat element, then structural stability is maintained, but the ease of maintenance and component replacement is reduced
Solution Approach 1:
The fastening system transitions from a static, permanent connection to a dynamic, reversible connection. The separate fastening elements can be detached and reattached, allowing the structure to adapt between stable operation and easy maintenance modes, enabling component replacement without permanent fastening.
4Reliability
If complex fastening systems are used to secure attachment parts, then fastening reliability is improved, but the device complexity and manufacturing difficulty increases
Solution Approach 1:
The fastening elements are designed to self-fasten to the molded bodies through mechanical engagement features. The separate fastening elements inherently provide reliable attachment without requiring additional complex fastening systems, inserts, or auxiliary components, achieving reliability through simple, self-contained design.

AI summary
A seat element for a vehicle seat may be formed from two molded bodies arranged one on top of the other. The seat element may have a plurality of separate fastening elements for fastening at least one attachment part to the seat element. The two molded bodies may be arranged in a contact-fitting manner in relation to one another and the separate fastening elements may be mechanically and detachably fastenable or fastened to at least one of the molded bodies. A vehicle seat having the at seat element is also provided.
