Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronics devices in motion, such as rotating display screens, can become unstable and pose risks of damage or injury due to mechanical instability, which existing technologies fail to adequately address.
Innovation Solution
A stability controlled system comprising a display configured to rotate, coupled to a stationary base with a motor and tilt sensors that communicate with a computing platform to regulate the rotation and ensure stability, preventing the device from spinning if instability is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display screen is rotated rapidly to generate 3D floating image effect, then the visual effect is improved, but the mechanical stability deteriorates causing vibration and potential toppling
Solution Approach 1:
The system performs preliminary stability assessment before allowing rotation to occur. The processor evaluates whether the display device is in a stable state (properly supported on a surface) before permitting the display screen to rotate, preventing unstable rotation that could cause toppling while still allowing the desired visual effects when conditions are safe.
Solution Approach 2:
The system continuously monitors stability conditions during operation and can adjust or terminate rotation based on real-time feedback. If the display device becomes unstable during rotation (e.g., picked up by user or misplaced), the system detects the changed support conditions and responds by stopping or preventing rotation to avoid damage or injury.
2Ease of operation
If the display screen is allowed to spin freely for visual effects, then the ease of operation is improved, but the harmful factors increase due to risk of damage and injury
Solution Approach 1:
The system applies preliminary anti-action by preventing rotation before unstable conditions can cause harm. By assessing support conditions in advance and blocking rotation when the device is not properly supported, the system eliminates the harmful effects of unstable rotation before they can occur, while still permitting free rotation when safely supported.
3Reliability
If stability control mechanisms are added to prevent toppling, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The system uses the existing processor and sensor infrastructure of the display device to perform stability assessment, rather than adding dedicated specialized hardware. The processor leverages available sensors (accelerometers, gyroscopes, or support surface detection) to evaluate stability conditions, achieving reliable stability control while minimizing additional device complexity by reusing existing components for multiple purposes.
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
The system effectively prevents damage and injury by controlling the rotation of the display screen, ensuring it remains stable and balanced, thereby maintaining a stable visual image and user safety.
Implementation Method 1
determine whether the display device is stable or unstable based on a status of the one or more tilt sensors
Implementation Method 2
a display screen configured to rotate around a vertical axis with the vertical axis substantially perpendicular to a display surface of the display screen

AI summary
A stability controlled system includes a computing platform having a hardware processor, a memory storing a software code, a moveable component, and a tilt sensor. The hardware processor executes the software code to monitor the tilt sensor to determine whether the system is at a tilt with respect to a support surface for the system. When the tilt sensor is sensing the tilt with respect to the support surface: when the moveable component is off, the software code prevents the moveable component from turning on, and when the moveable component is on, the software code performs one of (a) turning off the moveable component, and (b) slowing down a regular rate of motion of the moveable component. When the tilt sensor is not sensing the tilt with respect to the support surface, the software code permits the moveable component to be turned on and have the regular rate of motion.
