Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanisms like gears, conveyer belts, or screw mechanisms are used to convert rotation to linear movement, then the conversion can be achieved reliably, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the essential function of rotation-to-linear movement conversion from complex traditional mechanisms and implements it using a simple centrifugal force-based system. The revolving piece generates centrifugal force during rotation to directly push the target object, eliminating the need for gears, belts, or screw mechanisms while maintaining reliable movement conversion.
Solution Approach 2:
The system uses the rotational motion itself to generate the centrifugal force needed for linear movement conversion. The revolving piece automatically generates the required pushing force through its own rotation, without needing additional actuators or complex control mechanisms, making the system self-sufficient and simpler.
2Reliability
If traditional mechanisms like gears or conveyer belts are used, then rotation to linear movement conversion is achieved, but the cost of the system increases
Solution Approach 1:
The patent replaces expensive traditional mechanisms with a simple, inexpensive revolving piece that can be manufactured at low cost. The system uses basic components like a rotating arm with a centrifugal force-generating element, eliminating the need for costly gears, precision belts, or screw mechanisms, thereby significantly reducing manufacturing costs.
Solution Approach 2:
The patent extracts only the essential function of movement conversion from expensive traditional mechanisms and implements it using a simple centrifugal force-based system, reducing material costs, manufacturing complexity, and overall system expense while maintaining functional reliability.
3Reliability
If mechanisms like gears or screw mechanisms are used, then rotation to linear movement conversion is achieved, but the system requires specific configurations such as flat surfaces or holes in objects
Solution Approach 1:
The patent creates a universal system that can convert rotation to linear movement for various types of objects without requiring specific configurations. The revolving piece with centrifugal force generation can interact with different object shapes and surfaces, making the system adaptable to diverse applications including non-flat surfaces and telescopic structures.
Solution Approach 2:
Instead of requiring the target object to have specific features like flat surfaces or holes (as in traditional mechanisms), the patent inverts the approach by having the revolving piece actively adapt to the object's shape. The centrifugal force mechanism can contact and push various object geometries, reversing the traditional requirement structure and greatly enhancing versatility.

AI summary
A spinning arm that converts a rotational motion of a shaft to a linear movement of an object that includes a revolving piece and a rod. The lower end of the rod is connected to the shaft and the upper end is axially connected to the revolving piece in a state of tilting aside in relation to the rod so that the revolving axis line of the revolving piece crosses the rotation axis line of the rod. The revolving piece can move outwards and roll over the object when its tilt is from right to left. When the revolving piece rolls over the object in a first direction it exerts an upward force that moves the object upward, and when it rolls in a second direction it exerts a downward force that moves the object downward.
