Rotatable Tabletop Latch Mechanism for Vehicle Interiors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In confined spaces, such as vehicle interiors, existing tables with stowable tabletops often require complex hinge mechanisms that may not efficiently provide the necessary space or stability when rotated, and lack a reliable locking mechanism for various positions.
Innovation Solution
A table design featuring a vertical support structure with a rotatable tabletop that rotates about a longitudinal axis, coupled with a latching mechanism allowing selective locking and unlocking at multiple positions, ensuring stability and flexibility in space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tabletop is made stowable by pivoting at hinges, then space utilization is improved, but structural stability and reliability deteriorate
Solution Approach 1:
The tabletop is designed to be dynamically reconfigurable, allowing it to rotate between horizontal and vertical positions to adapt to different space requirements. This dynamic capability enables the table to transform its configuration based on operational needs while maintaining structural integrity through proper mechanical design
Solution Approach 2:
A latch mechanism serves as an intermediary component between the tabletop and support structure, providing reliable locking at various rotational positions. This intermediary element ensures that the tabletop remains securely fixed during use while still allowing easy repositioning when needed, thus resolving the contradiction between stability and adaptability
2Ease of operation
If a tabletop rotates about a longitudinal axis, then ease of operation and space flexibility are improved, but device complexity increases
Solution Approach 1:
The rotation mechanism is segmented into discrete functional components: a longitudinal axis, a latch mechanism with multiple locking positions, and a support structure. This segmentation allows each component to perform its specific function independently, simplifying the overall design and making the system easier to manufacture and maintain
Solution Approach 2:
The latch mechanism provides more locking positions than strictly necessary, allowing the tabletop to be secured at various angles and positions. This partial over-design ensures reliable operation across all possible configurations while maintaining a relatively simple mechanical structure
