Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lifting platform of computer room inspection robots often collides with obstacles such as ceilings or hanging objects due to outdated maps or uncalibrated sensors, leading to potential damage and operational inefficiencies.
Innovation Solution
A control device equipped with first and second distance measuring sensors and a safety redundant control circuit to measure and adjust the lifting platform's height dynamically, preventing collisions by generating elevation instructions and cutting power to the motor if necessary, ensuring safe operation even with map changes or sensor failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lifting platform raises to inspect devices at higher positions, then the inspection capability is improved, but the risk of collision with overhead obstacles increases
Solution Approach 1:
The patent applies preliminary anti-action by using distance measuring sensors to detect obstacles before the lifting platform reaches heights that would cause collision. The system proactively identifies overhead obstacles and prevents the platform from rising to dangerous heights, thereby eliminating the collision risk before it can materialize.
Solution Approach 2:
The patent implements feedback control through distance measuring sensors that continuously monitor the space above the lifting platform. When an obstacle is detected within a safe distance, the system provides feedback to the control device, which then adjusts or stops the lifting operation to maintain a safe distance from the obstacle.
2Reliability
If sensors are used to detect obstacles, then collision prevention is improved, but the system complexity increases
Solution Approach 1:
The patent replaces complex mechanical obstacle detection systems with electronic distance measuring sensors. Instead of using mechanical switches, pressure sensors, or complex mechanical linkages to detect obstacles, the system uses optical or electromagnetic sensing technologies that are more reliable, require less maintenance, and can be integrated more easily into the control system.
