Retractable Vehicle Screen Cover for Selective Information Exposure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle display screens often present a mix of primary and secondary information, making it difficult for users to focus on essential information while driving, as distinguishing between the two can be effortful.
Innovation Solution
A selectively retractable screen cover system with a door member rotatably mounted between fully exposed and partially exposed positions, actuated by a motor-driven mechanism involving a gear system and tine elements, allowing the user to control the exposure of the display screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a door member is rotatably mounted to cover the display screen, then the ability to focus attention on primary information is improved, but the device complexity increases due to additional mechanical components
Solution Approach 1:
The door member is segmented into multiple sections that can be independently positioned, allowing selective coverage of different portions of the display screen. This enables users to focus on specific areas (primary information) while leaving other areas visible (secondary information), resolving the contradiction by providing focused attention without requiring a complete cover.
Solution Approach 2:
The door member is designed with rotatable and movable capabilities, transitioning from a static cover to a dynamic element that can be positioned at various angles and locations. This dynamic positioning allows the system to adapt to different viewing needs, improving information focus while maintaining operational simplicity through intuitive movement.
2Ease of operation
If a motor-driven actuating mechanism is added to control the door member, then the ease of operation is improved, but the device complexity increases due to additional actuating components
Solution Approach 1:
The actuating mechanism is designed to be self-contained and self-regulating, with the motor automatically controlling the door member's movement based on simple input signals. The system includes self-limiting features that prevent over-travel and automatic positioning capabilities, reducing the need for complex control systems while maintaining ease of operation.
Solution Approach 2:
The patent replaces complex manual mechanical adjustment mechanisms with an electric motor-driven system. This substitution eliminates the need for manual manipulation of multiple mechanical components, providing easier operation through simple electrical control while the integrated design keeps the overall complexity manageable.
3Adaptability or versatility
If the door member can be positioned at multiple stops including partially exposed position, then the adaptability is improved, but the manufacturing precision requirements increase to ensure proper positioning
Solution Approach 1:
The positioning system incorporates feedback mechanisms that detect the door member's position and provide corrective adjustments to achieve accurate stopping positions. Sensors and control systems monitor the location of the door member and make real-time corrections, ensuring precise positioning at various stops without requiring extremely tight manufacturing tolerances on all components.
Solution Approach 2:
The system allows for adjustable positioning parameters, where the stop positions and exposure levels can be modified based on user preferences or operational conditions. This flexibility in parameters enables adaptability across different scenarios while the adjustment mechanisms compensate for variations in manufacturing precision through programmable or mechanically adjustable settings.
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
Enables users to easily focus on primary information by selectively hiding secondary information, improving attention on critical vehicle-related data without obstructing the entire screen.
Implementation Method 1
A motor includes a shaft connected to the actuating fork. The motor rotates the shaft to shift the door member between the first stop and the second stop.
Implementation Method 2
The door pivot is slidingly received between the first tine element and the second tine element.
Implementation Method 3
a first gear portion... a second gear portion meshing with the first gear portion
