Public Transport Seat Assembly with Selective Fixing and Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public transport vehicles, such as buses, face challenges in easily reconfiguring their seating arrangements to accommodate varying numbers and types of passengers, as fixed seats cannot be easily moved or removed.
Innovation Solution
A vehicular seat assembly with a structural portion fixed to the ground, featuring a hinge connection allowing the sitting portion to rotate and adjust positions, combined with selective fixing and coupling mechanisms that enable easy attachment and detachment from the ground, and rollers for movement when disengaged.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seats are fixed to the ground, then stability and safety are improved, but reconfigurability and ease of movement deteriorate
Solution Approach 1:
The seat assembly is divided into separable components: a structural portion that attaches to the ground and a seat portion that can be detached. This segmentation allows the seat to maintain stability when fixed while enabling easy reconfiguration by separating and relocating the seat portion to different positions or removing it entirely.
2Reliability
If seats are fixed to the ground, then stability is improved, but ease of operation and reconfiguration deteriorate
Solution Approach 1:
The seat assembly transitions from a static fixed state to a dynamic reconfigurable state through a coupling mechanism. The coupling portion allows the seat to be easily attached and detached from the ground, enabling quick reconfiguration of seating arrangements without complex tools or procedures, while maintaining stable fixation when attached.
3Adaptability or versatility
If seats are made movable, then reconfigurability is improved, but stability and reliability deteriorate
Solution Approach 1:
The coupling mechanism is pre-designed with coupling portions on both the structural portion and the ground that align and engage automatically. This preliminary preparation ensures that when the seat is attached, it achieves immediate stable fixation without requiring complex assembly steps, thus maintaining reliability while enabling movability.
