Innovation Solution

The use of hydraulic or electro-mechanic actuators controlled by a remote control unit to precisely move a top plate relative to a bottom plate, with a low-friction intermediate element and lever arms to achieve controlled, predictable movements, reducing manual intervention and enhancing safety and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual operation of jacking screws is used to align machinery, then the alignment process can be performed with simple equipment, but the alignment time is excessive and the quality depends on operator skill

Engineering Contradiction:
Improvealignment timeVSAvoidequipment complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical operation of jacking screws with hydraulic actuators that are controlled by a control unit. This substitution eliminates the need for manual intervention, significantly reduces alignment time, and ensures consistent quality regardless of operator skill, while the control unit provides automated precision control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The alignment system performs self-adjustment through automated control. The control unit receives input from measurement devices and automatically controls the hydraulic actuators to achieve precise alignment without requiring continuous manual intervention or high operator skill, making the system self-sufficient in the alignment process.

Inventive Principle:
Principle #25Self-service

2Reliability

If manual operation of jacking screws is used, then equipment simplicity is maintained, but operator safety is compromised due to direct manual intervention

Engineering Contradiction:
Improveoperator safetyVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces direct manual mechanical operation with remotely controlled hydraulic actuators. This eliminates the safety risks associated with operators working directly under or near heavy machinery during alignment, as all adjustments are made through automated hydraulic control from a safe distance.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The hydraulic actuator system serves as an intermediary between the control unit and the machinery alignment process. This intermediary mechanism allows precise control of heavy components without requiring direct manual contact, thereby protecting operators from potential injuries while maintaining control capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Manufacturing precision

If automated hydraulic actuators are used to control top plate movement, then alignment precision and predictability are improved, but the device complexity increases

Engineering Contradiction:
Improvealignment precisionVSAvoidactuator control complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The control unit receives feedback from measurement devices that monitor the alignment status of the machinery. Based on this feedback, the control unit automatically adjusts the hydraulic actuators to achieve precise alignment. This closed-loop control ensures high precision while automating the complex control processes.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses hydraulic actuators to provide controlled, predictable movement of the top plate. Hydraulic systems offer precise control capabilities and can generate the necessary force for heavy machinery alignment, achieving high manufacturing precision through fluid power control.

Inventive Principle:
Principle #29Pneumatics and hydraulics

4Duration of action of stationary object

If the low friction intermediate element is exposed, then mechanical simplicity is maintained, but contamination from dust, dirt and humidity reduces service time

Engineering Contradiction:
Improveservice timeVSAvoidprotection structure complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent introduces a protective housing or enclosure that surrounds the low friction intermediate element. This protective structure acts as an intermediary barrier that prevents dust, dirt, and humidity from contaminating the intermediate element, thereby extending its service life without significantly complicating the overall device design.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The protective housing creates a controlled environment around the low friction intermediate element, isolating it from harmful external factors such as dust, dirt, and humidity. This inert environment protection allows the intermediate element to maintain its low friction properties and extend service time without requiring complex active protection systems.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)
