Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a revolving-type processing blade is used to perform processing in the width direction, then position adjustment capability is improved, but processing time increases and processing efficiency deteriorates
Solution Approach 1:
The blade member is divided into an upper blade part and a lower blade part that can be pressed together. The processing blade is segmented into multiple sites along the perpendicular direction, allowing simultaneous multi-point processing in one pressing operation, thereby reducing the number of operations and improving efficiency while maintaining position accuracy through the pressing mechanism.
Solution Approach 2:
The blade member is designed with a moving mechanism that allows it to move in the perpendicular direction, enabling dynamic position adjustment. The attachable and detachable blade member can be repositioned along the conveyance direction to accommodate different processing positions, combining the benefits of position flexibility with reduced processing time.
2Productivity
If a guillotine blade is used for processing, then processing time is reduced and processing efficiency is improved, but position adjustment capability is lost and processing accuracy deteriorates
Solution Approach 1:
The guillotine-style pressing action is retained for high-speed processing, but a moving mechanism is added to enable the blade member to move in the perpendicular direction. This allows the blade to be dynamically repositioned to correct deviations in the width direction, combining the speed advantage of guillotine cutting with the position accuracy of adjustable blades.
Solution Approach 2:
A moving mechanism acts as an intermediary between the fixed guillotine pressing structure and the sheet material, enabling position adjustment without compromising the rapid pressing action. The mechanism translates positional corrections into blade movement while maintaining the high-speed pressing capability.
3Device complexity
If a fixed processing blade is used, then device complexity is reduced, but adaptability to different processing types and positions deteriorates
Solution Approach 1:
The blade member is segmented into an upper blade part and a lower blade part that can be separately attached and detached. This segmentation allows different blade configurations to be swapped easily, enabling adaptation to various processing types (cutting, perforation, creasing) while maintaining a relatively simple overall structure. The attachable design facilitates quick blade changes without complex reconfiguration.
Solution Approach 2:
The blade member with multiple processing blades formed at different sites can perform multiple processing functions simultaneously or alternatively. By pressing the upper and lower blade parts together, the system can handle cutting, perforation, and other processing types using a single universal blade assembly, reducing the need for multiple specialized blades while maintaining structural simplicity.
