Double Foldaway Seat Adapter Plate for FMVSS Floor Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Double foldaway seats in vehicles face challenges in securing them to the vehicle floor without compromising space efficiency, leading to failures under Federal Motor Vehicle Safety Standard (FMVSS) No. 207 due to inadequate attachment systems.
Innovation Solution
A seat assembly featuring an adapter plate with strategically positioned through-holes and threaded through-bores that allows for secure attachment to the vehicle floor, ensuring minimal volume usage and compliance with safety standards, including the use of bolts and washers for secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the base of the double foldaway seat is made very small and located as close to the vehicle wall as possible to minimize volume, then the volume occupied by the seat in the stowed position is reduced, but the seat fails to meet FMVSS No. 207 safety requirements due to inadequate attachment strength
Solution Approach 1:
The attachment system is divided into two distinct components: a small base for space efficiency and a separate adapter plate for strength. The adapter plate is secured to the vehicle floor with multiple bolts distributed across its surface, providing the necessary attachment strength while allowing the base to remain compact for minimal volume occupation.
Solution Approach 2:
The adapter plate serves as an intermediary component between the small base and the vehicle floor. It transfers and distributes the attachment forces from the compact base to the vehicle floor structure, enabling the base to remain small while still achieving safe attachment strength through the mediator's distributed bolt pattern.
2Volume of moving object
If the base is made compact to minimize volume, then space efficiency is improved, but the ease of secure attachment to the vehicle floor is compromised
Solution Approach 1:
The attachment function is segmented between the compact base and the larger adapter plate. The base remains small for space efficiency while the adapter plate provides multiple attachment points for bolts, making the secure attachment process easier and more reliable without requiring the base itself to be large.
Solution Approach 2:
The adapter plate acts as an intermediary that simplifies the attachment process. It provides a stable mounting surface with multiple pre-positioned bolt holes, making it easier to securely attach the compact base to the vehicle floor without compromising the base's small size or the attachment ease.
3Reliability
If multiple bolts and threaded through-bores are used in the adapter plate, then the reliability of seat attachment is improved, but the device complexity increases
Solution Approach 1:
The adapter plate serves multiple functions simultaneously: it provides structural reinforcement, distributes attachment forces, and offers multiple threaded through-bores for bolt attachment. This multi-functionality increases reliability without proportionally increasing complexity, as a single component performs several critical roles in the attachment system.
