Vehicle Seat Bottom With Integrated Structural Foam Frame Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a vehicle seat assembly that can be manufactured easily and economically while minimizing space, with improved aesthetic appeal and structural integrity, particularly in the design of the seat bottom and top assemblies.
Innovation Solution
The vehicle seat assembly incorporates a seat bottom frame assembly with structural foam and a cushion assembly featuring a flexible foam pad supported by a wire frame, secured together with attachment members and a latch system for stability during sudden deceleration, allowing for efficient assembly and space optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional separate frame and foam assembly methods are used, then manufacturing flexibility is maintained, but assembly complexity increases and manufacturing cost rises
Solution Approach 1:
The patent merges the frame assembly and foam pad into a single integrated unit by molding the foam directly onto the frame structure. This combination eliminates separate assembly steps, reduces the number of components, and simplifies the manufacturing process while maintaining structural integrity and comfort properties.
Solution Approach 2:
The integrated frame-foam assembly serves multiple functions simultaneously: it provides structural support through the frame, cushioning through the foam, and acts as a single assembly unit for easier installation and manufacturing. This multi-functionality reduces overall system complexity and manufacturing cost.
2Reliability
If more attachment members and latch systems are added, then stability during sudden deceleration improves, but device complexity increases
Solution Approach 1:
The attachment members and latch systems are pre-integrated into the frame-foam assembly during manufacturing. This preliminary action ensures that the security features are already in place and properly positioned before installation, providing reliable stability during sudden deceleration without requiring complex assembly procedures or additional components.
3Volume of moving object
If space optimization is prioritized in seat design, then vehicle compartment utilization improves, but manufacturing and assembly become more difficult
Solution Approach 1:
By combining the frame and foam into a single integrated assembly, the patent reduces the overall volume required for storage and installation while simplifying manufacturing. The merged structure eliminates gaps and interfaces between separate components, optimizing space utilization in the vehicle compartment and easing assembly operations.
