Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual actuation and level-checking of hydraulic jacks is used, then the stage can be leveled, but the process is time-consuming and not accurate
Solution Approach 1:
The system uses self-leveling sensors that automatically detect the stage's orientation and provide feedback to the control system, eliminating the need for manual level-checking. The sensors continuously monitor and adjust the hydraulic jack positions to maintain precise leveling automatically.
Solution Approach 2:
The patent implements a feedback mechanism where self-leveling sensors continuously monitor the stage's levelness and transmit this information to the controller, which then adjusts the hydraulic jacks accordingly. This closed-loop feedback system ensures high accuracy while reducing setup time significantly.
2Productivity
If manual actuation of hydraulic jacks is used, then the stage can be transformed between positions, but significant effort and time are required
Solution Approach 1:
The patent replaces manual mechanical actuation with an automated hydraulic control system. The controller receives input from self-leveling sensors and automatically commands the hydraulic jacks to move, eliminating manual effort and significantly increasing transformation speed between deployed and transport positions.
Solution Approach 2:
The system dynamically adjusts the hydraulic jack operations based on real-time feedback from sensors. The controller continuously monitors the stage position and automatically commands proportional valve adjustments to optimize the transformation process, making it both faster and more efficient than static manual operation.
3Ease of operation
If more persons and steps are used for setup and operation, then the stage can be controlled, but costs increase
Solution Approach 1:
The self-leveling sensors and automated control system perform leveling and positioning functions automatically without requiring multiple operators. The system monitors and adjusts itself, reducing the need for manual intervention and simplifying operation while maintaining control precision.
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 system significantly reduces setup time and enhances accuracy, providing faster and safer leveling of mobile stages, enabling efficient deployment and disassembly.
Implementation Method 1
self-leveling sensors ensure the stage is level between or during commands sent by the remote mobile computing device
Implementation Method 2
The receiver unit relays commands to a hydraulic system which then commands various valves to open and/or close, thereby transforming the mobile stage from a first, deployed position to a second, transport position or back

AI summary
A deployable mobile stage system with an automatic leveling system. A remote controlling device interfaces with an internal controller of the mobile stage for transforming the stage from a transport position to a deployed position. Multiple level sensors provide feedback to the controller of the stage to automatically level the stage using jacks and outriggers hydraulically or mechanically controlled by the controller. The level sensors could be 3-axis sensors which provide level data to the CPU of the internal controller, which then forms determinations as to which jacks to raise or lower, when, and at what rate.
