Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer room inspection robots face collisions with ceiling obstacles due to outdated maps or newly added hanging objects, as they lack real-time height adjustment capabilities, leading to potential damage and operational inefficiencies.
Innovation Solution
A control device for the lifting platform equipped with a first distance measuring sensor and processor to measure and adjust the height in real-time, preventing collisions by generating elevation instructions for the lifting motor, and incorporating a safety redundant control circuit to cut power if obstacles are too close, ensuring safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lifting platform uses a fixed map for navigation, then the device complexity is reduced, but the reliability decreases due to collisions with obstacles not in the map
Solution Approach 1:
The system performs preliminary distance measurement before the lifting platform rises, using a distance measuring sensor to detect obstacles above the platform. This advance detection allows the control device to prevent collision before it occurs, improving reliability without requiring complex real-time response systems.
Solution Approach 2:
The control device continuously receives distance measurement data from the sensor and adjusts the lifting platform's movement accordingly. This feedback mechanism ensures the platform stops or adjusts its ascent when obstacles are detected, maintaining high reliability while using a relatively simple control architecture.
2Adaptability or versatility
If the lifting platform rises to higher positions, then the inspection capability is improved, but the risk of collision with ceiling obstacles increases
Solution Approach 1:
The distance measuring sensor is positioned to detect obstacles before the lifting platform reaches them. The control device uses this information to prevent the platform from rising into collision zones, thereby eliminating the harmful effect of collision while maintaining the ability to inspect high positions.
Solution Approach 2:
The system measures the distance to potential obstacles before the lifting platform ascends to higher inspection positions. This preliminary measurement allows the system to safely extend its inspection coverage to ceiling-level devices while preventing collisions with hanging obstacles.
3Reliability
If real-time distance measurement is implemented, then collision prevention is improved, but the device complexity increases due to additional sensors and control circuits
Solution Approach 1:
The collision prevention function is extracted as a separate safety mechanism using a dedicated distance measuring sensor and control circuit. This modular approach allows real-time distance measurement to be added without significantly complicating the main lifting control system, as the safety function operates independently.
Solution Approach 2:
The distance measuring sensor acts as an intermediary between the lifting platform and potential obstacles. It provides critical distance information to the control device, enabling collision prevention without requiring direct interaction between the platform and obstacles, thus simplifying the overall system architecture.
