Rotatable Vehicle Display Panel for Exterior Message Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices for vehicles do not effectively allow communication of information from a user inside the vehicle to people outside, particularly when the user is not present, and lack the ability to display specific messages to predefined individuals without resorting to physical notes or manual placement on the dashboard.
Innovation Solution
A display device with a rotatable display panel and control circuitry that adjusts between positions to be visible either inside or outside the vehicle, using proximity sensors and electronic control units to manage visibility based on predefined physical environment conditions, enabling secure and timed display of messages or information to specific users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display panel is fixed inside the vehicle for user access, then information accessibility for interior users is improved, but communication capability with exterior persons deteriorates
Solution Approach 1:
The display panel is made rotatable about an axis parallel to its main edge, allowing it to dynamically change orientation between a first position facing the vehicle interior and a second position facing the vehicle exterior. This dynamic repositioning enables the same display panel to serve both interior users and exterior persons, resolving the contradiction between fixed interior accessibility and exterior communication capability.
2Adaptability or versatility
If the display panel is continuously activated for exterior visibility, then communication with exterior persons is improved, but energy consumption increases
Solution Approach 1:
A proximity sensor detects the presence of a person outside the vehicle and provides feedback to the control circuitry. The control circuitry then activates the display panel only when a person is detected within a predefined threshold distance, ensuring communication availability while avoiding continuous energy consumption. This feedback-based control resolves the contradiction between communication availability and energy efficiency.
3Adaptability or versatility
If general information is displayed for public viewing, then visibility to exterior persons is improved, but privacy for specific message delivery deteriorates
Solution Approach 1:
The control circuitry is configured to display different information based on the identity of the detected person. When a predefined person is identified, a specific personal message is displayed; otherwise, general information is shown. This local quality approach ensures that each person receives information appropriate to their identity, maintaining message privacy while ensuring visibility to the intended recipient.
