Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery-powered platforms, especially those equipped with depth cameras, face significant power consumption challenges due to the high demand of infrared emission for depth sensing, which further complicates battery functionality and longevity, especially when the systems are in motion.
Innovation Solution
Implementing a dynamic power management system that utilizes sensors to adjust the output power of depth cameras and other systems based on motion data, adjusting parameters such as infrared burst duration, intensity, and frequency, as well as frame rate, resolution, and capture area to optimize power usage while maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If infrared emission intensity and frequency are increased for depth sensing, then depth detection accuracy is improved, but battery power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of infrared emission parameters based on real-time motion detection. The system transitions from static fixed-power operation to dynamic power modulation, adjusting IR intensity and frequency according to whether the device is stationary or in motion, thereby optimizing the balance between depth detection accuracy and power consumption.
Solution Approach 2:
The system changes physical parameters of infrared emission (intensity, frequency, duration) based on detected motion state. When motion is detected, the system adjusts these parameters to reduce power consumption while maintaining acceptable depth sensing performance, directly addressing the contradiction between measurement precision and energy usage.
2Measurement precision
If frame rate and resolution are increased for image quality, then image quality is improved, but power consumption increases
Solution Approach 1:
The patent dynamically adjusts frame rate and resolution parameters based on motion detection results. When the device is stationary or motion is minimal, the system operates at higher frame rates and resolutions for optimal image quality. When motion is detected, the system reduces these parameters to lower power consumption, resolving the contradiction between image quality and energy usage.
Solution Approach 2:
The system uses feedback from motion sensors to continuously adjust imaging parameters. The motion detection output serves as feedback that triggers dynamic reconfiguration of frame rate and resolution settings, creating a closed-loop control system that optimizes the trade-off between image quality and power consumption in real-time.
3Area of stationary object
If capture area is expanded for broader coverage, then coverage is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of capture area based on motion state. When the device is stationary, the system uses a larger capture area for comprehensive coverage. When motion is detected, the system reduces the capture area to minimize power consumption, as full coverage is less critical during dynamic conditions. This dynamic adaptation resolves the contradiction between coverage and energy usage.
