Removable Railway Table Mount With Sliding Lock Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for rearranging seats and tables in railway vehicles are tedious due to the need to dismantle, move, and reassemble tables, which is time-consuming and labor-intensive.
Innovation Solution
A comfort device with a table and fastening means that include a lateral fixed support with a sliding rail and a complementary housing, along with retractable locking mechanisms, allowing for easy assembly and disassembly by sliding and locking the fixing member on the lateral support, facilitating rapid reconfiguration without requiring extensive manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fastening systems are used for tables in railway vehicles, then the tables can be securely fixed to the structure, but the assembly and disassembly operations are tedious and time-consuming
Solution Approach 1:
The fastening system is divided into separate modular components: a fixed support attached to the vehicle structure, a fixing member attached to the table, and retractable locking means. This segmentation allows the table to be quickly assembled and disassembled by simply engaging and disengaging the locking mechanisms, transforming a tedious manual process into a simple operational task.
Solution Approach 2:
The locking means are designed to be retractable, transitioning between engaged and disengaged states. This dynamic capability allows the fastening system to adapt between a locked secure state during operation and an unlocked removable state for reconfiguration, enabling rapid assembly and disassembly without complex tools or procedures.
2Adaptability or versatility
If traditional fastening systems are used for tables in railway vehicles, then the tables can be securely fixed, but the reorganization of seating layouts requires extensive manual effort
Solution Approach 1:
By segmenting the fastening system into independent fixed support and fixing member components with simple locking mechanisms, the table can be easily detached and repositioned. This enables flexible reorganization of seating layouts in railway vehicles without requiring extensive manual effort, as each table can be independently and quickly reconfigured.
Solution Approach 2:
The fixed support and fixing member design allows the same fastening system to be used across multiple table positions and configurations within the railway vehicle. This universal application enables versatile layout reorganization, where tables can be moved to different locations and arranged in various configurations using the same standardized fastening components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
