Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle enclosure systems face issues with manual operation of movable windows, increased complexity due to pneumatic systems, reduced ventilation, and discomfort from inadequate heating and air conditioning control, leading to distractions and reduced visibility for drivers.
Innovation Solution
A barrier door with a powered ventilation system incorporating a movable window panel, actuator, and controller, allowing controlled airflow and temperature regulation, and a latch mechanism for enhanced security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a manual movable window is incorporated in the barrier door, then ventilation and air flow are improved, but the driver is subjected to distractions and ergonomic concerns
Solution Approach 1:
The system uses sensors to automatically detect when the barrier door is open and activates the movable window panel and ventilation system without requiring manual driver intervention. The system serves itself by autonomously managing ventilation based on door position, eliminating the need for the driver to manually operate windows while maintaining air flow.
Solution Approach 2:
The manual mechanical operation of the movable window panel is replaced with an automated electromechanical system. Motors or actuators drive the window panels based on sensor input, substituting the mechanical manual cranking or sliding action with an automated system that responds to door position detection.
2Quantity of substance
If the movable window is left open to improve ventilation, then air flow is improved, but the protective nature of the barrier door is reduced
Solution Approach 1:
The movable window panels are designed to dynamically adjust between open and closed positions based on real-time conditions. When the barrier door is closed, windows remain closed for protection. When the barrier door is open, windows automatically open to provide ventilation. This dynamic adaptation allows the system to maintain protection when needed and provide ventilation when safe.
Solution Approach 2:
The system incorporates sensors that continuously monitor the position of the barrier door and provide feedback to the control system. This feedback mechanism triggers automatic opening or closing of the movable window panels based on whether the barrier door is open or closed, ensuring that ventilation is provided only when the protective barrier is not in place.
3Reliability
If the movable window is closed to maintain protection, then security is improved, but ventilation and air flow are reduced
Solution Approach 1:
The ventilation system automatically activates when the barrier door is detected as open, providing air flow without requiring the driver to manually open windows. The system monitors its own state and self-adjusts to provide ventilation when conditions are safe, eliminating the trade-off between protection and ventilation.
4Ease of operation
If pneumatic assist is incorporated for manual door operation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The pneumatic assist system is replaced with an automated electromechanical actuation system. Instead of using compressed air cylinders and manual triggers, the system uses motors controlled by sensors and a control unit to automatically open and close the barrier door and movable window panels, eliminating the need for complex pneumatic infrastructure while maintaining ease of operation.
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
The solution provides both protection and comfort for drivers by reducing distractions, improving ventilation, and maintaining visibility through controlled airflow and temperature management.
Implementation Method 1
an actuator, and a controller. The actuator may move the inner movable portion between different positions to control flow of air between a protective enclosure and a volume outside of the protective enclosure
Implementation Method 2
The powered ventilation system may incorporate one or more blower fans to allow the driver to control the level of ventilation
Implementation Method 3
The existing heating and air conditioning vents in and around the operator's station may have been originally designed to work in a space that did not incorporate a retrofitted barrier door

AI summary
A barrier door may include a section including an outer stationary portion and an inner movable portion disposed within the outer stationary portion, an actuator, and a controller. The actuator may move the inner movable portion between different positions to control flow of air between a protective enclosure and a volume outside of the protective enclosure. The controller may monitor one or more operating characteristics of the actuator and may modify an operational status of the actuator to control the flow of the air between the protective enclosure and the volume outside of the protective enclosure based at least in part on the one or more operating characteristics.
