Vehicle Display Automatic Positioning System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laptop computers are limited in their usefulness due to the lack of ergonomic solutions for display and keyboard positioning during use in vehicles, such as airplanes or cars, where users often experience discomfort and strain from improper viewing angles and positions.
Innovation Solution
A display system that includes a flat panel display screen mounted within a vehicle, an occupant position sensor system, a memory with a look-up table, and a control system that automatically adjusts the display position based on the occupant's position, using sensors like pressure sensors or transducers to optimize viewing distance, tilt angles, and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display is mounted at a fixed position in the vehicle, then the device complexity is reduced, but the ergonomic adaptability to different occupants and positions deteriorates
Solution Approach 1:
The display system transitions from a fixed static position to a dynamically adjustable position. The display can move along a track mechanism and rotate to different angles, allowing it to adapt to various occupant positions and ergonomic requirements while maintaining a relatively simple overall system architecture.
Solution Approach 2:
The display positioning system is divided into independent functional modules: a motorized positioning mechanism, a rotation joint, and a control system. This segmentation allows each component to perform its specific function independently, reducing the complexity of the overall system while enabling versatile positioning capabilities.
2Ease of operation
If manual adjustment of display position is required, then the system complexity is reduced, but the ease of operation deteriorates due to requiring user intervention
Solution Approach 1:
The display system automatically adjusts its own position and orientation based on sensor input from the occupant detection system. The control system processes occupant position data and autonomously commands the display to move to the optimal position, eliminating the need for manual adjustment while maintaining system simplicity through automated self-regulation.
Solution Approach 2:
The system incorporates a feedback loop where sensors continuously monitor occupant position and characteristics, the control system processes this information, and the display position is adjusted accordingly. This closed-loop feedback mechanism enables automatic ergonomic optimization without requiring complex user interaction interfaces.
3Loss of time
If the display position is manually set for each user, then the automation complexity is reduced, but the loss of time for setup increases
Solution Approach 1:
The system performs preliminary positioning actions automatically upon detecting an occupant. The control system pre-calculates the optimal display position based on occupant characteristics and immediately commands the positioning mechanism to move to that position, eliminating setup time and providing instant ergonomic optimization without manual intervention.
Solution Approach 2:
The manual mechanical adjustment process is replaced with an automated electromechanical positioning system. Motors and actuators substitute for manual user actions, automatically moving the display to the correct position based on sensor data, thereby eliminating the time loss associated with manual setup while maintaining system simplicity.

AI summary
A display system mounted within a vehicle is provided, where the system monitors the user's position within the vehicle's seat and automatically adjusts the location of the display to compensate for variations in the size or seating position of the user, thereby helping to alleviate the eye strain, fatigue, neck and back pain that often accompany the improper use of a monitor for an extended period of time.
