Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object support devices struggle to facilitate the rotation of large and heavy machinery without requiring excessive torque, often leading to instability and the risk of the object and stand falling over, as users lack the necessary musculature to apply torque effectively.
Innovation Solution
A rotational coupling device with a housing and gear arrangement that connects a motivator shaft to a rotational drive shaft, allowing for slower and more controlled rotation of the machinery stand, reducing the need for high torque and preventing unsteady applications that could cause the object and stand to fall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotational mechanism is used to rotate large and heavy machinery, then the ability to adjust orientation is improved, but large amounts of torque are required which users cannot provide
Solution Approach 1:
A gear arrangement acts as an intermediary mechanism between the user input and the rotational drive shaft. The gears transmit and modify the rotational force, providing mechanical advantage that reduces the torque a user must directly apply while still achieving the desired rotation of heavy machinery.
Solution Approach 2:
The gear arrangement changes the parameters of rotational motion by reducing the rotational speed while increasing the torque output. This parameter transformation allows the system to convert easy-to-apply low-torque input into high-torque output suitable for rotating heavy machinery.
2Productivity
If users apply torque directly to rotate heavy machinery, then rotation can be achieved, but the object and stand may fall over due to unsteady application
Solution Approach 1:
The gear arrangement serves as a mediator that smooths out the transmission of rotational force. By distributing the torque through multiple gear contacts and providing mechanical advantage, the system reduces the need for users to apply force directly and unsteadily, thereby preventing instability and potential falling during rotation.
3Ease of operation
If large handles are added to provide greater leverage, then user control over rotation is improved incrementally, but the stands remain hard and dangerous to operate
Solution Approach 1:
Instead of simply enlarging handles for leverage, the invention introduces a gear arrangement as an intermediary that provides mechanical advantage. This approach improves user control more effectively than larger handles alone, while avoiding the need for excessively large handle dimensions that would increase device complexity and space requirements.
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
Enables users to rotate large and heavy objects with less effort and stability, as the device transfers rotational motion from the motivator shaft to the machinery stand through a speed-reducing gear arrangement, enhancing user control and preventing accidents.
Implementation Method 1
The motivator shaft and the rotational drive shaft may be operably connected together with a gear arrangement, which may be contained within the housing, with rotation of the motivator shaft resulting in rotation of the rotational drive shaft
Implementation Method 2
The gear arrangement may be configured as a speed reducing arrangement so that the rotational drive shaft rotates with a slower rate of rotation than the motivator shaft

AI summary
A rotational coupling device may include a housing which may be coupled to a stationary coupler. The stationary coupler may be used to engage or couple the device to a machinery stand. A motivator shaft may be positioned on one side of the housing and a rotational drive shaft may be positioned on the other side of the housing. The motivator shaft and the rotational drive shaft may be operably connected together with a gear arrangement with rotation of the motivator shaft resulting in rotation of the rotational drive shaft that is of a reduced rate compared to the motivator shaft. The rotational drive shaft may be coupled or connected to the rotational assembly via a rotational coupler thereby allowing rotational motion provided by the motivator shaft to be transferred through the rotational drive shaft to the rotational assembly of the machinery stand to which the device is engaged.
