Solution Overview
Problem
Wall-climbing robots face issues with weight and control instability due to long cables and pipes for power and raw material supply, leading to control failures, energy inefficiency, and stability problems, especially when operating at high altitudes with crosswinds.
Innovation Solution
A multifunctional robot system with a movable supply station connected to robot units via branch power cables and water pipes, where the supply station is equipped with a power supply system, adsorption device, and moving device, allowing it to follow the robot units and reduce the weight and size of the units by separating the supply from the driving mechanism, and incorporating approach bridge plates and recycling cabins for obstacle navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the wall-climbing robot is provided with a water tank or coating box and control components, then the robot can operate independently, but the robot becomes very heavy and may fall due to huge gravity
Solution Approach 1:
The patent extracts heavy components (water tank, coating box, control components) from the robot body and places them on the roof. The robot retains only essential lightweight components for climbing and basic operation, while material supply and power control are provided externally through cables and pipes.
Solution Approach 2:
The patent introduces cables and pipes as intermediary elements to connect the lightweight robot on the wall with the supply equipment on the roof. These intermediaries transmit power, control signals, and materials without requiring the robot to carry heavy components.
2Ease of operation
If raw material supply device is placed on the roof with long pipes, then materials can be supplied to the robot, but control becomes unstable due to severe time lag
Solution Approach 1:
The patent extracts the raw material supply device from the robot and places it on the roof, connecting it through pipes. This separation allows the supply system to be optimized independently, with the robot receiving materials without carrying heavy tanks.
Solution Approach 2:
The patent implements dynamic control where the robot can autonomously control the opening and closing of valves on its own body, enabling real-time adjustment of material flow without relying on long-distance signal transmission that causes time lag.
3Ease of operation
If power control component is placed on the roof with long cable, then power can be supplied to the robot, but control becomes unstable due to severe time lag
Solution Approach 1:
The patent extracts the power control component from the robot and places it on the roof, connecting it through a long cable. This allows the power supply system to be separated from the robot body.
Solution Approach 2:
The patent implements dynamic power control where the robot can autonomously control its own power distribution switches, enabling real-time adjustment of power consumption without relying on long-distance signal transmission that causes time lag.
4Adaptability or versatility
If the robot moves horizontally from position A to position B, then the robot can access different working areas, but the cable becomes a high inertia load that severely affects movement performance
Solution Approach 1:
The patent implements a self-service mechanism where the robot autonomously controls the reeling and unreeling of the cable during movement. The robot can pay out cable when moving away from the roof and reel it in when returning, reducing the cable's inertial resistance and improving movement performance.
5Reliability
If the cable is reeled or unreeled according to robot movement, then the robot can maintain connection with supply device, but it is difficult to accurately control cable length and speed due to complex flexible line body behavior
Solution Approach 1:
The patent implements feedback control where sensors on the robot detect its position and movement state, and this information is transmitted to the roof control system. The roof system automatically adjusts cable reeling speed and length based on real-time robot position, maintaining optimal connection without manual intervention.
6Reliability
If adsorption device operates in maximum adsorption force state to resist cable drag, then the robot can maintain stability, but energy consumption becomes very high
Solution Approach 1:
The patent implements dynamic adsorption force control where the adsorption device adjusts its force output based on real-time requirements. When the robot is stationary or moving slowly, lower adsorption force is sufficient. When the robot accelerates or encounters strong winds, adsorption force increases automatically, optimizing energy consumption while maintaining stability.
