Vehicle Display Angle Adjustment via Seat-Back Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems require manual adjustments by occupants to maintain a comfortable viewing angle, which becomes inconvenient when occupants change positions or when multiple occupants have different preferred viewing angles.
Innovation Solution
An automatic display adjustment system that includes a controller coupled with motors to detect the seat-back angle of occupants and adjust the display angle accordingly, allowing for individual or averaged display angle settings based on detected angles and optional additional adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment is used, then the display can be positioned at a favorite viewing angle, but the occupant needs to re-adjust whenever changing position or posture
Solution Approach 1:
The system pre-establishes the relationship between seat-back angle and optimal display angle through automated detection and calculation. When an occupant reclines the seat, the controller automatically detects the new seat-back angle and calculates the corresponding optimal display angle in advance, eliminating the need for manual re-adjustment and reducing time loss.
Solution Approach 2:
The system continuously monitors the seat-back angle through sensors and provides real-time feedback to the controller. Based on this feedback, the controller automatically adjusts the display angle to maintain the optimal viewing position, creating a closed-loop control system that eliminates manual intervention and reduces adjustment time.
2Adaptability or versatility
If the display is maintained at default angle or adjusted by one occupant, then the display position is fixed, but it cannot properly balance viewing angles of multiple occupants with different preferences
Solution Approach 1:
The system dynamically adjusts the display angle based on real-time detection of seat-back angles from multiple occupants. Instead of a fixed default position, the display angle changes adaptively according to the seating positions and preferences of different occupants, enabling the system to accommodate multiple users with different viewing preferences.
Solution Approach 2:
The controller calculates optimal display angles by analyzing parameters such as seat-back angles, occupant positions, and viewing preferences. By changing the display angle parameter dynamically based on these inputs, the system can optimize viewing conditions for different occupants without requiring manual adjustment by each user.
3Extent of automation
If automatic adjustment based on seat-back angle is implemented, then manual adjustments are eliminated, but the system complexity increases with controller and sensor integration
Solution Approach 1:
The controller serves multiple functions: it detects seat-back angles through integrated sensors, calculates optimal display angles based on detected parameters, and actuates motors to adjust the display position. By consolidating detection, calculation, and control functions into a single controller unit, the system achieves high automation while minimizing the number of separate components and reducing overall system complexity.
Solution Approach 2:
The controller acts as an intermediary between the seat sensors and the display motor. It receives signals from seat-back angle sensors, processes the information to determine optimal display positioning, and sends control signals to the display motor. This intermediary role simplifies the system architecture by providing a centralized control point that coordinates between different subsystems.

AI summary
An automatic display adjustment system for a vehicle may include a controller coupled to a display and at least one motor for adjusting the display. The controller may be configured to detect a seat-back angle of a seat occupied by an occupant and determine a display angle based on the detected seat-back angle. The controller may be further configured to generate a control signal to actuate at least one motor for adjusting the display according to the determined display angle.
