Linked Tilting Plate Mechanism for Directional Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tilting devices experience unintended tilting of movable plates due to the weight of objects arranged opposite to the rotation shaft, leading to momentum in the wrong direction.
Innovation Solution
A tilting device configuration with an upper movable plate, an intermediate movable plate, and a first lower movable plate, connected via actuators and rotation shafts, where a first connecting member restricts the movement of the upper movable plate to prevent unintended tilting by integrating its rotation with the intermediate and lower plates, ensuring coaxial alignment of rotation shafts to maintain intended tilting directions.

Engineering Contradiction Analysis
1Ease of operation
If the link mechanism rotates the movable plate around the end portion opposite to the rotation shaft, then the movable plate can be tilted to one side, but a momentum in an unintended direction opposite to the tilting direction is generated due to the own weight of the object to be tilted
Solution Approach 1:
The patent introduces a counterweight mechanism that balances the gravitational force acting on the movable plate. By positioning the center of gravity of the movable plate at a specific location and using the connecting member to create a counterbalancing effect, the system prevents unintended tilting caused by the weight of the object being tilted, thereby maintaining reliable directional control.
Solution Approach 2:
The patent adds a new dimensional constraint by introducing a connecting member that links the movable plate to a fixed point in space. This connecting member constrains the movement of the movable plate not only in the tilting direction but also in the perpendicular direction, effectively adding a spatial dimension to the control mechanism and preventing unintended rotation.
2Area of moving object
If the movable plate is made larger to accommodate the object to be tilted, then the object can be securely held, but the momentum in unintended direction increases
Solution Approach 1:
The connecting member acts as a counterbalancing element that offsets the harmful momentum generated by the large movable plate. By strategically positioning the connecting member and adjusting its length, the system creates a counteracting torque that neutralizes the unintended tilting momentum caused by the plate's size and the object's weight.
Solution Approach 2:
The patent applies different functional qualities to different parts of the movable plate. The connecting member is positioned at a specific location (not at the center or at the opposite end) to create a localized counterbalancing effect. This local quality approach allows the plate to maintain its large area for holding objects while preventing unintended tilting through the strategically placed connecting member.
