Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual force is applied to press down the saw blade, then the cutting can be performed, but excessive manpower and time are required, making the cutting ineffective
Solution Approach 1:
The patent replaces the manual mechanical pressing system with a motor-driven rotational cutting system. The motor rotates the cutting blade at high speed, and the rotational motion combined with the movable platform's linear motion enables cutting without manual force application, thus improving productivity and reducing time consumption.
Solution Approach 2:
The patent introduces dynamic motion by rotating the cutting blade instead of using static linear pressing. The blade rotates while the platform moves linearly towards the workpiece, creating a dynamic cutting action that is more efficient than manual pressing and reduces both manpower and time requirements.
2Manufacturing precision
If manual force is applied to press down the saw, then cutting can be achieved, but deviation of angle from right cutting angle occurs, causing undesired cutting quality
Solution Approach 1:
The patent replaces manual angle control with a motorized rotational system guided by a movable platform. The platform's linear rails or guides ensure the blade approaches the workpiece at the correct angle, eliminating human error in angle control and improving cutting quality.
Solution Approach 2:
The cutting system is self-regulating in terms of angle maintenance. The motorized rotation and platform movement work together to automatically maintain the correct cutting angle without requiring operator intervention or skill, ensuring consistent cutting quality.
3Measurement precision
If conventional saw cutting is used, then cutting can be performed, but high precision cutting cannot be achieved, resulting in low accuracy
Solution Approach 1:
The patent uses dynamic rotational motion of the blade combined with controlled linear motion of the platform to achieve high precision cutting. The rotation speed and platform movement are coordinated to ensure accurate cutting, and the system's complexity is justified by the significant improvement in measurement and cutting precision.
Solution Approach 2:
The patent replaces the simple manual saw mechanism with a motorized system that incorporates rotational motion and platform movement. This substitution increases device complexity but enables high precision cutting through controlled, repeatable motion patterns that are impossible to achieve manually.

AI summary
The present invention relates to a rotational cutting machine, it has a base, on the base is first motive power source to bring the cutting blade rotate; near the cutting blade is a fixing tool that tightly holds an object to be cut, on the side the fixing tool is a second motive power source to turn the fixing tool together with the object to be cut; the fixing tool is set on a platform that is adjustable; when cutting an object, the first motive power source turns the blade rotate, while the second motive power source also turns the object to be cut rotate, through the platform that is movable, the fixing tool is moved towards the cutting blade, such that the object tightly held in the fixing tool can be in contact with the cutting blade, the object then can be cut efficiently and accurately.
