Fold-Flat Vehicle Seatback Mount for a Removable Tray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle seats with integrated tablets are limited in functionality as the tablet is permanently attached and cannot be used independently in different locations, restricting its usability and ergonomics.
Innovation Solution
A vehicle seat with a folding backrest equipped with specific fastening means that allow an independent tablet to be securely fixed in an upright position on the rear face, enabling it to serve as a support for reading or writing, and allowing easy orientation towards adjacent seats without the need for additional fixing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tablet is permanently attached to the backrest, then the tablet is securely positioned, but the tablet cannot be moved to different locations or used independently
Solution Approach 1:
The backrest is divided into multiple zones with different fastening capabilities: a first zone with a first fastening system and a second zone with a second fastening system. This segmentation allows the tablet to be positioned in different locations depending on user needs, improving versatility while keeping each individual fastening system relatively simple.
Solution Approach 2:
The backrest structure is designed to serve multiple functions: it can hold the tablet in a first position using the first fastening system, or in a second position using the second fastening system. This multi-functionality allows the same structure to adapt to different usage scenarios without requiring completely separate mounting mechanisms.
2Adaptability or versatility
If additional fastening components are added to enable tablet movement, then the tablet can be positioned flexibly, but the device complexity increases
Solution Approach 1:
Different zones of the backrest are equipped with different fastening characteristics tailored to their specific functions. The first zone has fastening means optimized for one type of positioning, while the second zone has fastening means optimized for another type of positioning. This local differentiation achieves versatile tablet positioning without requiring the entire backrest to have complex fastening capabilities.
3Adaptability or versatility
If the backrest structure is modified to accommodate multiple positioning options, then the tablet can be used in different positions, but the manufacturing complexity increases
Solution Approach 1:
The backrest is designed with dynamic positioning capabilities, allowing it to accommodate the tablet in multiple positions. The first and second fastening systems enable the tablet to be securely held in different operational positions, providing adaptability while using relatively simple mechanical fastening mechanisms that can be manufactured using conventional processes.
