Motor Scooter Pivoting Display for Glare Reduction and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor scooter displays are vulnerable to reflections, environmental damage, and unauthorized access, which affects road safety and security, especially in shared vehicle scenarios where physical ignition switches are impractical.
Innovation Solution
A pivoting display device with an actuator and control system that adjusts based on inputs, such as NFC/RFID signals, to protect the display and ensure only authorized users can access information, while reducing glare through light sensor-controlled positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a glass layer is added to protect the display from environmental damage and vandalism, then the protection of the display is improved, but reflections occur on the display making it difficult to read and causing driver blinding
Solution Approach 1:
The display device is made dynamically adjustable through an actuator mechanism that allows the display to pivot between different angular positions. This dynamic adjustment enables the display to adapt to varying lighting conditions and viewing angles, optimizing readability while maintaining protection.
Solution Approach 2:
The display's angular position parameter is changed dynamically based on detected glare conditions. By adjusting the display angle, the system modifies the reflection direction to move glare away from the driver's line of sight, thereby reducing harmful reflections while maintaining display protection.
2Reliability
If a physical ignition switch is provided on the handlebar assembly, then the anti-theft function is achieved, but it is not possible to give every potential driver a key in shared vehicle scenarios
Solution Approach 1:
The mechanical ignition switch system is replaced with an electronic authentication system using NFC/RFID technology. This substitution eliminates the need for physical keys while maintaining secure access control, enabling multiple users to authenticate electronically for shared vehicle scenarios.
Solution Approach 2:
The authentication device integrates multiple functions including NFC/RFID authentication, display control, and vehicle activation into a single system. This multi-functional approach allows the same device to serve both security and user interface purposes, enhancing versatility for shared vehicle use.
3Ease of operation
If the display is made accessible and visible to the driver, then the driving information is readable, but the display becomes exposed to external environmental factors and vandalism when parked
Solution Approach 1:
The display transitions between static protected state and dynamic visible state based on operational context. When the vehicle is parked, the display remains in a protected closed position. When activated, it pivots to an accessible position for readability, then returns to protected state when deactivated.
Solution Approach 2:
The display automatically pivots to a protected position preliminary to potential damage when the vehicle is parked or when not in use. This preliminary protective action prevents exposure to environmental factors and vandalism before they can cause damage.
4Ease of operation
If the display is positioned to be visible to the driver during operation, then the information is accessible, but glare from reflections can blind the driver and impact road safety
Solution Approach 1:
The display angular position parameter is dynamically adjusted based on detected glare conditions and driver position. By changing the display angle, the system modifies reflection directions to move glare away from the driver's line of sight while maintaining information accessibility.
Solution Approach 2:
The system uses light sensors to detect glare conditions and provides feedback to the control device, which then adjusts the display position accordingly. This closed-loop feedback mechanism continuously optimizes display positioning to minimize glare while maintaining readability.

AI summary
Various problems arise in display devices for vehicles. These problems are solved by a display device (10) with a base (11), comprising the following: - a display (20), said display (20) being mounted rotatably on the base (11) by means of a display hinge (21); - an actuator (30), particularly an electric motor (30), that is arranged in functional connection with the display (20) and/or display hinge (21) and is designed to pivot the display (20) about said display hinge (21) from a first position (P1) into a second position (P2); - a control device (40) for actuating the actuator (30); and - a communication device (50) for receiving an input (51), particularly wirelessly; said control device (40) being designed to actuate the actuator (30) in reaction to at least one input (51) such that the display (20) is pivoted from the first position (P1) into the second position (P2).
