Bus Door Control With Obstruction Reversal and Remote Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bus drivers face challenges in controlling bus doors, particularly when they cannot see obstructions, leading to potential injuries or damages, and they need to manage door access remotely for security and comfort purposes.
Innovation Solution
An apparatus with an actuator that controls a pair of doors, allowing them to automatically reverse when encountering objects and be operated remotely through a mobile device for secure and convenient access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bus driver manually controls the doors to close them, then the doors can be secured, but the driver cannot see obstructions in the path leading to potential injury or damage
Solution Approach 1:
The patent replaces manual mechanical door control with an automated actuator system that uses sensors to detect obstructions. The actuator automatically reverses door motion when an obstruction is detected, eliminating the need for the driver to manually operate doors while maintaining secure closing functionality.
Solution Approach 2:
The system incorporates sensors that provide feedback about the door path environment. When the sensor detects an obstruction in the door path, it sends a signal to the actuator to reverse the door motion, preventing injury or damage while ensuring the door can still close properly when the path is clear.
2Ease of operation
If the bus driver leaves the doors unlocked for remote access, then the driver can re-enter the bus easily, but unauthorized persons may enter the bus
Solution Approach 1:
The patent introduces a remote control system as an intermediary between the driver and the door actuator. The driver can control the door actuator wirelessly from outside the bus using a mobile device, allowing convenient re-entry while maintaining security through controlled access.
Solution Approach 2:
The system enables the driver to independently control door access from outside the bus without needing assistance from passengers or other personnel. The remote control capability allows the driver to unlock and enter the bus on their own while maintaining security protocols.
3Temperature
If the bus driver leaves the bus running while away, then the interior remains comfortable (warm or cool), but the driver cannot monitor conditions or control doors remotely
Solution Approach 1:
The patent uses wireless communication technology as an intermediary to connect the driver's mobile device with the bus control systems. This allows the driver to remotely monitor temperature conditions and control door operations from outside the bus while the vehicle remains running and the interior stays comfortable.

AI summary
An apparatus for controlling bus doors (14, 16) that are arranged as a pair of doors that move in coordinated relation between door open positions and door closed positions, enables passengers to access an interior area (12) of a bus (10). The apparatus includes an actuator (28, 226). The actuator includes a drive lever (34, 228) that is selectively rotationally movable between rotational positions in which both of the doors are in the open positions and in the closed positions. Exemplary arrangements include at least one controller (128) that is operative to prevent the doors from causing damage to or from being damaged by engagement with obstructions. The controller further enables a bus driver or other authorized user to control access to the interior area of the bus using a user mobile device (144).
