Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning module is installed in the climbing robot platform, then the risk of worker injury is reduced, but the cleaning module has limited movement and cannot effectively clean building facades having various shapes
Solution Approach 1:
The patent applies dynamics by making the cleaning module movable relative to the climbing robot platform. The cleaning module is equipped with a driving device that enables it to move forward and backward along the building facade, allowing it to adapt to various building shapes and surfaces while maintaining worker safety benefits
2Force
If the hoist motor is used to change the center of mass location, then the contact strength of wheels with the building facade can be varied, but the limited weight and movement range make it difficult to bring the cleaning module into contact in parallel with the building facade
Solution Approach 1:
The patent uses dynamics by enabling the cleaning module to move independently along the building facade. This movement capability, combined with the adjustable center of mass, allows the cleaning module to achieve parallel contact with the building facade by positioning itself appropriately rather than relying solely on weight adjustment
Solution Approach 2:
The cleaning module performs self-service by using its own driving device to move and position itself. This self-movement capability allows the module to autonomously adjust its position to achieve parallel contact with the building facade, reducing reliance on the hoist motor's limited weight adjustment range
3Device complexity
If the rope feed point is fixed, then the structure is simple, but the cleaning robot cannot easily adapt to different building shapes and maintain parallel contact
Solution Approach 1:
The patent applies dynamics by making the rope feed point movable rather than fixed. The feeding device includes a moving mechanism that allows the rope feed point to adjust its position, enabling the cleaning robot to adapt to different building shapes and maintain proper contact while keeping the overall structure relatively simple
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the climbing robot to maintain parallel contact with building facades, easily attach and manage ropes, navigate obstacles, and ensure safe operation even when power is interrupted, preventing rope damage and ensuring efficient cleaning operations.
Implementation Method 1
a lifting device installed in the body, moving up by winding a rope and moving down by unwinding the rope
Implementation Method 2
a first guide member to feed the rope, a second guide member rotatably connected to the first guide member to guide the rope
Implementation Method 3
when the opening/closing member closes the feed point, the rope may be pressed by the first roller and the third roller
Implementation Method 4
including a propeller to generate a propulsive force
Implementation Method 5
each lifting pulley may be connected with a differential gear device which distributes the torque transmitted from the lift motor
