Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing POV rotation display devices have short display times and ineffective information transmission due to high power consumption, especially when mounted on wheels, and are not optimized for varying environmental and operational conditions.
Innovation Solution
A display method for a wheel rotation imaging device that identifies situational modes using operation information, such as ambient light and vehicle speed, to adjust power consumption modes, allowing for extended display duration and targeted information transmission by selecting between off display, lighting effect, normal image, and contour image displays based on power thresholds and situational conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the wheel rotation imaging device operates at high power consumption to maintain display quality, then the display effect is improved, but the display duration becomes very short
Solution Approach 1:
The patent implements dynamic power consumption adjustment by switching between different power modes (first power consumption mode with higher power for quality display, and second power consumption mode with lower power for extended duration) based on real-time situational analysis. This dynamic adaptation allows the system to optimize the balance between display quality and duration according to environmental conditions, vehicle state, and power availability.
Solution Approach 2:
The system changes operational parameters by adjusting power consumption levels based on multiple factors including ambient light intensity, wheel speed, vehicle acceleration, current time, location, and remaining power. By modifying these parameters dynamically, the device can extend display duration while maintaining acceptable display quality under varying conditions.
2Loss of information
If the device displays continuously to maximize information transmission, then the display coverage is improved, but the power is consumed faster reducing overall utility
Solution Approach 1:
The system employs feedback mechanisms by continuously monitoring operation information (ambient light, wheel speed, acceleration, time, location, power level) and using this feedback to adjust power consumption modes. This closed-loop control ensures that information transmission is optimized based on real-time conditions while preventing excessive power consumption that would reduce overall utility.
Solution Approach 2:
The patent implements dynamic power consumption adjustment by switching between different power modes (first power consumption mode with higher power for quality display, and second power consumption mode with lower power for extended duration) based on real-time situational analysis. This dynamic adaptation allows the system to optimize the balance between display quality and duration according to environmental conditions, vehicle state, and power availability.
3Device complexity
If the device operates without situational awareness to simplify control, then the device complexity is reduced, but the power utilization efficiency decreases
Solution Approach 1:
The control system integrates multiple functions into a unified situational mode identification module that processes diverse operation information (light sensing, speed detection, acceleration measurement, time tracking, location monitoring, power management) and coordinates power mode selection. This multi-functional approach consolidates complexity while maximizing power utilization efficiency through comprehensive situational awareness.
