Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If arc guide and worm drive are used to provide tilt, then tilt function is achieved, but production accuracy demands increase, cost increases, and vibration transmission occurs
Solution Approach 1:
The patent replaces the traditional arc guide and worm drive mechanical system with a pivotally mounted movable part that achieves tilt through direct rotational movement. This substitution eliminates the complex toothed elements and their associated manufacturing precision demands while reducing vibration transmission.
Solution Approach 2:
The patent extracts and removes the arc guide and worm drive components from the tilt mechanism, retaining only the essential pivotal mounting structure. This extraction eliminates the sources of high manufacturing precision demands and vibration while preserving the core tilt functionality.
2Adaptability or versatility
If arc guide and worm drive are used to provide tilt, then tilt function is achieved, but cost increases
Solution Approach 1:
The patent replaces the expensive arc guide and worm drive mechanical system with a simpler pivotally mounted structure. This substitution reduces manufacturing complexity and associated costs while maintaining the required tilt function.
Solution Approach 2:
The patent employs a simpler, more cost-effective pivotal mounting structure instead of expensive precision mechanical components. This approach reduces overall system cost while achieving the same functional outcome.
3Adaptability or versatility
If large part of manipulation stage is tilted, then tilt angle changes are achieved, but parasitic movement increases
Solution Approach 1:
The patent segments the manipulation stage into a fixed part and a separately pivotally mounted movable part. This segmentation isolates the tilt function to a specific component, minimizing parasitic movement of the entire stage while maintaining full tilt angle adjustment capability.
Solution Approach 2:
The patent extracts the tilt functionality from the entire manipulation stage and concentrates it in a separately pivotally mounted movable part. This extraction reduces the mass being tilted and minimizes parasitic movement while preserving the required tilt angle range.
4Ease of operation
If manual control rod with recesses is used, then tilt angle setting is achieved, but arbitrary tilt angles cannot be set and machine tilt is impossible
Solution Approach 1:
The patent replaces the manual control rod with recesses mechanical system with a pivotally mounted movable part that can be positioned and locked at arbitrary angles. This substitution enables continuous tilt angle adjustment and machine-controlled tilt while maintaining ease of operation through positioning and locking mechanisms.
5Ease of operation
If control rod with recesses is used, then tilt angle setting is achieved, but setting complexity increases
Solution Approach 1:
The patent extracts and removes the complex control rod with multiple recesses mechanism, replacing it with a simpler pivotally mounted movable part. This extraction reduces setting complexity while maintaining the ability to achieve desired tilt angles through direct pivotal movement and positioning.
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 solution effectively reduces parasitic movements and enhances the accuracy of tilt angle settings, improving the reliability and precision of the tilting mechanism while minimizing vibrations and production costs.
Implementation Method 1
the blade reduces the amount of unwanted parasitic movement in the direction parallel to the tilting axis, since the blade reduces the possibility of movement in that direction by attachment of one end thereof to the bottom side of the movable part
Implementation Method 2
the movement apparatus comprises a blade and a linear actuator, wherein the blade is attached at one end to the bottom side of the movable part and is connected at the opposite end to the linear actuator
Implementation Method 3
the movable part is pivotally mounted on the fixed part

AI summary
A tilting element of a manipulation stage uses a movement apparatus comprising a linear actuator attached to a fixed part and connected to a blade. The blade is attached at an end to a bottom side of a movable part to tilt the movable part relative to the fixed part. A tilt angle of the movable part relative to the fixed part is changed by extending and retracting the movable part of the linear actuator and thus winding and unwinding of the blade on the bottom side of the movable part.
