Tilting Plate Linkage for Unintended Tilt Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tilting devices often result in unintended tilting of a movable plate due to the weight of an object placed opposite the rotation shaft, leading to momentum in an unintended 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 ensuring the rotation shafts are coaxial, and the connecting member is arranged to intersect the rotation shafts, preventing interference and simplifying the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the link mechanism rotates the movable plate around the end portion on one side, then the movable plate can be tilted to one side, but when an object is arranged at the end portion opposite to the rotation shaft, a momentum in an unintended direction opposite to the tilting direction is generated due to the own weight of the object, and the movable plate may be tilted in the unintended direction
Solution Approach 1:
The movable plate is divided into an upper movable plate and a lower movable plate, with the link mechanism connected to both. This segmentation allows the mechanism to control tilting while preventing unintended movement by distributing the control function across multiple components.
Solution Approach 2:
The link mechanism acts as an intermediary between the actuators and the movable plates, transmitting force in a controlled manner. It connects the upper and lower movable plates and works with the rotation shafts to prevent unintended tilting while enabling controlled tilting in the desired direction.
2Reliability
If the first connecting member is arranged to connect the upper movable plate and the lower movable plate at end portions opposite to the connection with the rotation shafts, then the movement of the upper movable plate is restricted to suppress unintended tilting, but the configuration becomes more complex
Solution Approach 1:
The first connecting member combines multiple functions: it connects the upper movable plate to the lower movable plate, restricts unintended movement through its specific arrangement, and works in conjunction with the rotation shafts to enable controlled tilting. This merging of functions reduces the need for additional separate components.
Solution Approach 2:
The first connecting member serves multiple purposes within a single component: it provides structural connection, restricts unintended tilting movement, and facilitates controlled tilting when working with the rotation shafts. This multi-functionality simplifies the overall device configuration despite the sophisticated control requirements.

Function Achieved in This Case
The solution effectively suppresses unintended tilting of the movable plate by ensuring the rotation shafts are coaxial, preventing momentum in unintended directions and simplifying the device configuration, while allowing precise control of the tilt angle using gas expansion and contraction mechanisms.
Implementation Method 1
when the upper movable plate is rotated around the axis of the upper rotation shaft of the upper movable plate and the intermediate movable plate, the first connecting member rotates integrally with the upper movable plate around the axis of the second connecting rotation shaft of the first connecting member and the first lower movable plate
Implementation Method 2
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
