Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a force generating actuator is used to lift up the movable roll support to release the gripped workpiece, then the workpiece can be released, but a large capacity motor is required leading to high power consumption
Solution Approach 1:
The patent changes the direction of the slider's movement from vertical to horizontal, while the rod-hole mechanism converts this horizontal motion into vertical motion of the roll support. This dimensional transformation allows the use of a smaller motor that moves the slider horizontally, rather than requiring a large motor to directly lift the heavy roll support vertically.
Solution Approach 2:
The rod and hole with inclined surfaces act as an intermediary mechanism between the slider and the roll support. The slider moves horizontally along the inclined surfaces, and this motion is transmitted through the rod-hole interaction to produce vertical movement of the roll support, effectively mediating the force transmission and reducing the power requirement.
2Force
If a large capacity motor is used to lift the movable roll support, then the gripping function can be achieved, but the durability is reduced
Solution Approach 1:
By changing the motor's movement direction to horizontal and using the rod-hole mechanism for vertical conversion, the system reduces the mechanical stress and load on the motor, thereby improving durability while maintaining the necessary gripping force.
Solution Approach 2:
The inclined surfaces of the hole create a mechanical advantage that counteracts the weight of the roll support and the gripping force requirements, reducing the burden on the motor and improving system reliability.
3Force
If the slider moves in horizontal direction along the roll support member with rod and hole engagement, then the roll support member moves in vertical direction, but the mechanism complexity increases
Solution Approach 1:
The rod and hole assembly serves multiple functions: it guides the slider's horizontal movement, converts this motion to vertical movement of the roll support, and provides the inclined surface mechanism for force multiplication. This multi-functionality reduces the need for separate components, thereby limiting the increase in overall mechanism complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves low power consumption and enhanced durability by providing a large material gripping force with small drive force, allowing for high-precision, intermittent transportation of plate materials.
Implementation Method 1
A hole 118 having an inclined surface 118a inclined with respect to the horizontal direction is formed in the slider 117. When the slider 117 moves in the horizontal direction, the rod 119 sliding on the inclined surface 118a enables the upper roll support member 110 to move in the vertical direction.

AI summary
Provided is a plate material feeding device that can achieve reduced power consumption, improve durability, and supply plate material with high precision. A plate material feeding device is provided with a housing, a lower roll, an upper roll, a lower roll support member for supporting the lower roll, an upper roll support member for supporting the upper roll, and a slider movable in the horizontal direction along the upper roll support member, and can feed plate material clamped by the lower roll and the upper roll. A hole is provided in the slider, and a rod is provided in the upper roll support member. By inserting at least part of the rod in the hole in a slidable manner, the upper roll support member can move in the vertical direction when the slider moves in the horizontal direction.
