Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vacuum motor is used to tilt the object during coating or inspection, then the tilting function is achieved, but the motor is prone to overheating and unsatisfactory operation
Solution Approach 1:
The patent replaces the vacuum motor-driven tilting mechanism with a mechanical linkage system consisting of a tilting module, connecting rod, and pivot point. This mechanical substitution eliminates the vacuum motor from the tilting function, avoiding overheating and operational reliability issues while maintaining the ability to tilt the reaction module to desired angles during coating and inspection processes.
2Adaptability or versatility
If a vacuum motor is used for tilting, then the object can be tilted for coating and inspection, but it causes trouble in the detection program and coating process
Solution Approach 1:
The mechanical linkage system provides direct, reliable control over the reaction module's tilting angle without the interference and failures associated with vacuum motors. This ensures uninterrupted coating and detection operations, maintaining productivity while achieving the necessary adaptability for different processing angles.
3Manufacturing precision
If multi-axial movement and tilting are implemented, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the positioning system into distinct modular components: a base module, a reaction module, a tilting module, and a rotating module. Each module performs a specific function (vertical movement, horizontal movement, tilting, rotation), allowing for precise multi-axial positioning while maintaining manageable complexity through functional segmentation and independent control of each degree of freedom.

AI summary
A multi-axis mechanism device includes: a base module, a first moving module, a second moving module, a third moving module, a reaction module, a tilting module and a rotating module. The first moving module performs a first axial movement relative to the movable bearing platform to drive the reaction module to be displaced relative to the movable bearing platform. The second moving module performs a second axial movement relative to the first moving module to drive the reaction module to be displaced relative to the first moving module. The third moving module drives the movable bearing platform to perform a third axial movement relative to the module body to drive the reaction module to be displaced relative to the module body. The reaction module is driven by the tilting module to perform titling action and by the rotating module to perform rotating operation relative to the central axis.
