Bus Grab Pole Side Wall Mounting for Circulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing public transport vehicles face challenges with vertical support bars that obstruct user circulation, are prone to degradation, and offer limited balance support due to inadequate attachment methods, particularly when fixed to the floor and ceiling.
Innovation Solution
A public transport vehicle with a vertical support column fixed to the side wall at both an upper and lower attachment zone, providing increased rigidity and resistance, and allowing for flexible repositioning and maintenance without floor attachment, thus enhancing user safety and operational convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the vertical support bar is fixed to the floor and ceiling, then the attachment provides structural support, but it creates obstacles for user circulation and hinders cleaning operations
Solution Approach 1:
The patent removes the attachment from the floor area and relocates it to the side wall. The vertical support bar is now fixed only to the side wall at upper and lower zones, extracting the harmful floor attachment while preserving the support function through wall mounting.
2Strength
If the vertical support bar is fixed to the floor, then it provides support function, but the attachment zone degrades more rapidly over time
Solution Approach 1:
The patent extracts the attachment from the high-wear floor area and relocates it to the side wall, which is less subject to damage and degradation. This relocation preserves the support function while improving long-term reliability.
3Stability of the object's composition
If the vertical support bar is fixed to the floor with reinforcement, then attachment stability is improved, but device complexity increases due to required floor reinforcement at each location
Solution Approach 1:
The patent eliminates the need for floor reinforcement by removing the floor attachment requirement entirely. The side wall attachment zones provide sufficient stability without requiring complex floor reinforcement structures at each bar location.
4Strength
If the vertical support bar is fixed to the side wall at upper and lower zones, then fixing rigidity and resistance to forces are improved, but the attachment structure becomes more complex
Solution Approach 1:
The patent transitions from single-point floor/ceiling attachment to distributed side wall attachment at upper and lower zones. This dimensional change in attachment distribution provides enhanced rigidity and force resistance through the vertical spacing of attachment points along the side wall.
