Motorized Vehicle Window Screen Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles used as temporary sleeping quarters often experience disruptions due to pests entering through open windows, as existing window systems fail to effectively prevent insect intrusion while allowing ventilation.
Innovation Solution
A vehicle window assembly incorporating a motor-operated movable window, a screen assembly, and a controller that engages the screen assembly within the window opening, using seals and hooks to secure the screen in place, ensuring effective pest prevention while allowing ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the window is left open for ventilation, then air circulation is improved, but pests can enter the vehicle
Solution Approach 1:
The window system is segmented into multiple functional layers: the movable window pane, the screen assembly with mesh screen, and sealing components. This segmentation allows the window to provide ventilation through the screen while blocking pests, resolving the contradiction between open window benefits and pest protection needs
Solution Approach 2:
The screen assembly acts as an intermediary element between the interior vehicle space and the exterior environment. It mediates the conflicting requirements by allowing air passage while preventing pest entry, enabling ventilation without direct exposure to outdoor pests
2Object-affected harmful factors
If a screen assembly is added to prevent pests, then pest protection is improved, but device complexity increases
Solution Approach 1:
The screen assembly is designed to perform multiple functions simultaneously: pest prevention, ventilation allowance, and integration with the existing window system. The motorized actuation system provides universal control for both window operation and screen deployment, reducing overall system complexity despite added functionality
Solution Approach 2:
The screen assembly is merged with the window system as an integrated unit, sharing common structural elements, mounting mechanisms, and actuation systems. This merging approach allows pest protection functionality to be added without creating a completely separate complex system
3Reliability
If the motor applies force to hold the screen assembly, then screen security is improved, but force application control complexity increases
Solution Approach 1:
The motor control system incorporates feedback mechanisms that monitor the force applied to the screen assembly and adjust accordingly. This feedback ensures reliable screen holding while preventing excessive force that could damage components, achieving security without requiring complex manual control
Data Source
AI summary
A vehicle window assembly is disclosed that includes a screen assembly mountable within an opening and a motor operable to move a movable window to engage the screen assembly and hold the screen assembly within the opening. A controller is provided that is configured to operate the motor to apply a desired force against the screen assembly with the movable window to hold the screen assembly within the opening.
