Solution Overview
Problem
Existing ultraviolet sterilization robots struggle to irradiate ultraviolet rays effectively to high positions due to their size or inability to maneuver compactly.
Innovation Solution
A robot design featuring a flexible plate with vertical portions and chains, ultraviolet lamps, and a rotator mechanism that allows the sterilization module to elevate and adjust to high positions while maintaining a compact size, enhanced by reflectors and guide grooves for stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the robot uses a conventional ultraviolet sterilization method with a fixed sterilization module, then the structure is simple and compact, but it cannot irradiate ultraviolet rays to high positions effectively
Solution Approach 1:
The sterilization module is designed with dynamic adjustability, allowing it to change its position and orientation. The module can be elevated vertically and rotated to face different directions, enabling it to reach high positions and irradiate ultraviolet rays effectively without requiring a larger overall robot structure.
Solution Approach 2:
The sterilization module is nested within the robot body when not in use, allowing the robot to maintain a compact size. When sterilization of high positions is needed, the module is deployed outward and elevated, providing extended functionality without permanently increasing the robot's footprint.
2Length of moving object
If the robot increases its size to irradiate ultraviolet rays to high positions, then the sterilization coverage is improved, but the robot cannot maneuver in compact spaces
Solution Approach 1:
The robot employs a telescopic or articulated arm mechanism that allows the sterilization module to extend to high positions dynamically. This enables the robot to maintain a compact base size for maneuverability while achieving extended reach for high-position sterilization when needed.
Solution Approach 2:
The sterilization module and its support structure are designed to nest within the robot body during movement and storage. This allows the robot to operate in compact spaces with a small profile while still having the capability to extend to high positions for sterilization tasks.
3Area of stationary object
If the robot uses a large sterilization module to cover high positions, then the sterilization coverage is improved, but the robot structure becomes too large and complex
Solution Approach 1:
The sterilization system is segmented into multiple ultraviolet lamps distributed along the extendable arm or module. This allows the coverage area to be increased by extending the arm rather than by enlarging a single bulky module, maintaining structural compactness while achieving wide coverage.
Solution Approach 2:
The sterilization module uses dynamic extension mechanisms to increase coverage area only when needed. The module can be extended to reach high positions and cover larger areas during sterilization operations, then retracted to a compact configuration for movement and storage, avoiding permanent structural complexity.
