Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive devices for adjusting operating elements in gas and oil exploitation are bulky and difficult to handle, requiring large motors that generate excessive heat, necessitating separate cooling systems, which are impractical for underwater applications.
Innovation Solution
The use of multiple smaller driving motors with a disk- or wheel-shaped revolution introducing device, connected via drive shafts, allows for a compact design with efficient thermal distribution, eliminating the need for separate cooling systems and facilitating easier mounting and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a large driving motor is used to generate the necessary power for adjusting the operating element, then the power requirement is met, but the drive device becomes bulky and difficult to handle
Solution Approach 1:
The patent divides the single large driving motor into multiple smaller driving motors (at least two) that are distributed around the revolution introducing device. Each motor connects to the drive shaft via a revolution introducing device (such as a worm wheel), collectively providing the necessary power while reducing the volume of each individual motor and the overall drive device configuration.
2Power
If a large driving motor is used to generate the necessary power, then the power requirement is met, but the heat development increases necessitating separate cooling devices
Solution Approach 1:
By segmenting the single large motor into multiple smaller motors, the heat generation is distributed across several sources rather than concentrated in one location. This distributed thermal load allows for more effective heat dissipation through the housing surfaces and eliminates the need for complex separate cooling devices, especially important for underwater applications.
3Power
If a large driving motor is used, then the power requirement is met, but the drive device becomes difficult to mount and service underwater
Solution Approach 1:
The drive device is segmented into multiple smaller components (multiple motors, drive shafts, and revolution introducing devices) that can be more easily manufactured, transported, and assembled. This modular configuration simplifies underwater mounting and servicing operations, as smaller components are more manageable for divers or telecontrolled vehicles compared to a single large motor assembly.
4Volume of moving object
If multiple smaller driving motors are used with distributed arrangement, then the volume is reduced and thermal distribution is improved, but the device complexity increases
Solution Approach 1:
Multiple drive shafts and their associated revolution introducing devices are merged into a single integrated housing structure. The housing combines support for multiple motors, mounting for multiple drive shafts, and integration of multiple revolution introducing devices into one unified assembly, reducing the overall system complexity despite having multiple motor components.

AI summary
A drive device serves for adjusting an operating element for a valve, a throttle, a blow-out preventor or the like, in particular in the field of gas and oil production, the operating element being actively connected to at least one driving motor via a drive train, and at least one transmission changing unit being arranged in the drive train for converting a revolution of the driving motor into a revolution of the operating element and/or a revolution/linear motion converter being arranged for converting the revolution of the driving motor into a linear motion of the operating element. In order to also have a very compact design in case of a high possible performance and to simultaneously permit a good thermal distribution within the drive device, so that separate cooling devices for carrying off the generated lost heat are superfluous, the drive train comprises at least one essentially disk- or wheel-shaped revolution introducing device which is actively connected with at least two drive shafts driven by separate driving motors.
