Solution Overview
Problem
Existing transport devices with narrow degree of freedom between the transport belt and blade face challenges in ease of assembly and effective wiping of the outer peripheral surface, limiting the flexibility and efficiency of the device.
Innovation Solution
Incorporating a first frame that holds the blade, an elastic member to bias the frame for contact, and a second frame that supports the first frame for movement along the normal direction of the outer peripheral surface, increasing the degree of freedom and allowing for adjustable biasing force through the use of springs and sliding members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the degree of freedom between the transport belt and the blade is narrow, then the structure is simple, but the ease of assembly is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the first frame movable relative to the second frame along the normal direction of the outer peripheral surface. This allows the blade assembly to dynamically adjust its position and contact pressure with the transport belt, providing both assembly flexibility and operational adaptability without excessive structural complexity
Solution Approach 2:
The patent segments the frame structure into two separate frames: a second frame that is fixed and a first frame that is movable. This segmentation allows independent optimization of each frame's function, simplifying the assembly process while maintaining the necessary degree of freedom for effective blade contact with the transport belt
2Reliability
If the blade is fixed rigidly to the transport belt, then the structure is stable, but the wiping effectiveness is reduced
Solution Approach 1:
The movable first frame allows the blade to dynamically adjust its contact pressure and position with the transport belt during operation. This dynamic adjustment ensures consistent wiping effectiveness across different operating conditions while maintaining overall structural stability through the fixed second frame
Solution Approach 2:
The patent enables parameter changes by allowing the first frame to move along the normal direction, which changes the contact pressure and overlap length parameters between the blade and transport belt. This provides optimal wiping effectiveness under varying conditions while maintaining structural reliability
