Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate drive motors are used for upper and lower rolls to increase conveyance capacity, then conveyance capacity is improved, but device width increases and installation flexibility decreases
Solution Approach 1:
The patent combines both drive motors (upper-roll drive motor and lower-roll drive motor) and positions them on the same side of the device. This merging of motor positions allows the device width to be reduced while still maintaining the capability to drive both rolls independently for high conveyance capacity
Solution Approach 2:
Instead of distributing motors on opposite sides (horizontal arrangement), the patent arranges motors on the same side, utilizing vertical or depth-based positioning. This dimensional reorganization reduces the horizontal width of the device while preserving motor functionality
2Productivity
If separate drive motors are used for upper and lower rolls to increase conveyance capacity, then conveyance capacity is improved, but device complexity and wire routing area increase
Solution Approach 1:
By positioning both drive motors on the same side, the patent merges the motor mounting area and wire routing paths. This consolidation reduces the overall area required for wire routing and simplifies the complexity of managing multiple motor connections
3Reliability
If mechanical coupling is used to synchronize upper and lower rolls, then synchronization is improved, but conveyance capacity is limited
Solution Approach 1:
The patent segments the drive system by providing separate drive motors for the upper roll and lower roll, while still achieving synchronization through mechanical coupling via gears. This segmentation allows each roll to be driven independently for high conveyance capacity while maintaining synchronization
Solution Approach 2:
The patent introduces gears as an intermediary mechanism between the drive motors and rolls. The upper gear and lower gear mesh to provide mechanical coupling and synchronization, while still allowing independent motor control for high conveyance capacity
4Reliability
If drive motors are positioned on both right and left sides to synchronize rolls, then synchronization is improved, but maintainability deteriorates
Solution Approach 1:
The patent merges the position of both drive motors to the same side of the device. This consolidation improves maintainability by reducing the area where wires are routed and concentrating all motor-related components in one accessible location
