Umbrella Head Tracking via Camera and Motor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional umbrellas are difficult to accurately position over the center of a user's head, affecting their rain-proof effectiveness.
Innovation Solution
An umbrella with a photographing assembly, control assembly, and driving mechanism that takes a photograph of the user's head, processes the image to generate adjustment signals, and adjusts the canopy's position and angle to ensure optimal coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the umbrella position is adjusted by the user based on sensation, then the operation is simple, but the positioning precision is insufficient
Solution Approach 1:
The umbrella system performs self-positioning by automatically detecting the user's head position through the photographing assembly and adjusting the canopy position via the driving mechanism without requiring manual intervention, thereby achieving precise positioning while maintaining operational simplicity
Solution Approach 2:
The patent replaces the manual sensation-based adjustment mechanism with an automated system using photographing assembly for detection, control assembly for processing, and driving mechanism for execution, substituting mechanical manual operation with an integrated automated control system
2Adaptability or versatility
If the umbrella uses a fixed canopy position, then the device complexity is low, but the adaptability to different users and postures is poor
Solution Approach 1:
The patent transforms the fixed canopy position into a dynamic adjustable position through the driving mechanism that can rotate the first and second rotating portions and extend/retract the telescopic mechanical shaft, allowing the canopy to adapt to different user positions and postures in real-time
Solution Approach 2:
The system establishes a feedback loop where the photographing assembly continuously monitors the user's head position, the control assembly processes this information to determine position deviations, and the driving mechanism adjusts the canopy position accordingly, enabling adaptive positioning that responds to changing user conditions
