Solution Overview
Problem
Existing autonomous cleaning devices face challenges in accurately capturing environmental images in varying light conditions and protecting their sensors and modules from collisions, leading to reduced reliability and efficiency.
Innovation Solution
The autonomous mobile device incorporates a line laser module with a camera device and an infrared fill-in lamp, protected by a buffer component, which allows ambient light entry and provides additional illumination when needed, along with a buffer component to absorb collision impacts, enhancing sensor accuracy and device reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera device is exposed on the front side to capture environmental images, then the sensor accuracy is improved, but the device becomes vulnerable to collision damage
Solution Approach 1:
The front side structure is segmented into a removable buffer component that can be separated from the device main body. This allows the camera device to be protected during collisions while maintaining accessibility for image capture when the buffer is in place or removed as needed.
Solution Approach 2:
A buffer component is provided on the front side of the device main body, positioned between potential obstacles and the camera device. This buffer absorbs collision impacts before they reach the camera, protecting the sensor from damage while allowing the device to maintain its obstacle detection functionality.
2Reliability
If a buffer component is added to protect the camera device, then the device reliability is improved, but the structural complexity increases
Solution Approach 1:
The buffer component serves multiple functions: it protects the camera device from collision damage, provides a mounting structure for the infrared fill-in lamp, and can be designed as a removable element that doesn't permanently complicate the device structure. This multi-functionality justifies the added structural element.
3Measurement precision
If ambient light entry is enabled for the camera device, then the environmental image capture accuracy is improved, but the device becomes sensitive to light interference
Solution Approach 1:
The infrared fill-in lamp is activated periodically or on-demand based on ambient light conditions, rather than continuously. This allows the camera to capture environmental images using natural ambient light when available, while supplementing with infrared illumination only when needed, thus reducing unnecessary light interference while maintaining image capture accuracy.
