Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a facade working robot uses adsorption apparatuses to move on building facades, then it can carry out construction work on facades, but it falls down when the adsorption mechanism fails, resulting in serious safety risks
Solution Approach 1:
The patent introduces a safety rope system that provides backup support before a fall can occur. The safety rope is pre-configured and connected to the working robot, so when the adsorption mechanism fails, the safety rope immediately prevents the robot from falling, cushioning the potential disaster before it happens.
Solution Approach 2:
The safety rope acts as an intermediary element between the working robot and the building structure. It mediates the safety function by providing a separate support path that is independent of the adsorption mechanism, allowing the robot to be supported even when adsorption fails.
2Stability of the object's composition
If a facade working robot relies on friction on work surface to balance gravity and working tool gravity, then it can maintain position, but it has very limited load-bearing capacity and work capacity
Solution Approach 1:
The patent uses the safety rope system to provide an upward counteracting force that balances the gravity of the working robot and its tools. The rope tension acts as a counterweight force, allowing the robot to carry heavier tools without increasing the friction requirement on the building surface.
3Length of moving object
If rope coiling apparatuses are installed near the top of building to suspend working apparatus, then working height can be increased, but when vertical distance to rope coiling apparatuses is very short, the angle between ropes approaches 180 degrees requiring infinite tension
Solution Approach 1:
The patent transitions from a two-dimensional planar rope arrangement to a three-dimensional spatial configuration. By allowing the mobile rope node to move freely in 3D space and positioning rope coiling apparatuses at multiple locations, the system can maintain optimal rope angles even at high working heights, avoiding the 180-degree angle problem.
Solution Approach 2:
The patent introduces a mobile rope node that can dynamically change its position in space. This mobility allows the rope system to continuously adjust and maintain optimal geometric configurations, preventing the ropes from approaching 180 degrees even when the working apparatus is near the top of the building.
