Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional cutting stage is used without air circulation structures, then the structure is simple, but foreign substances such as particles and fumes accumulate on the cutting stage, contaminating it and affecting display module quality
Solution Approach 1:
The cutting stage is divided into multiple cell areas by partition walls, with each cell equipped with independent air supply and suction systems. This segmentation allows targeted removal of foreign substances from different regions while maintaining overall structural organization and managing complexity through modular design
Solution Approach 2:
Air supply nozzles and suction ports are integrated into the stage structure, using pneumatic flow to remove foreign substances. Air is supplied through nozzles in each cell area and extracted through suction ports, creating a controlled airflow field that prevents contamination without requiring complex mechanical cleaning mechanisms
2Object-affected harmful factors
If air supply structures are added to remove foreign substances, then the removal effectiveness improves, but the device complexity increases due to additional pipes and nozzles
Solution Approach 1:
The air supply system is merged with the stage structure itself, with nozzles integrated into the partition walls and body member. The suction system is similarly integrated with suction ports built into the stage. This merging eliminates the need for separate external air supply equipment, reducing overall device complexity while maintaining effective foreign substance removal
Solution Approach 2:
The stage structure serves multiple functions: it supports the substrate for cutting, provides structural rigidity, and simultaneously acts as the air supply and suction system through its integrated nozzles and ports. This multi-functionality reduces the need for additional dedicated components, managing complexity while achieving effective contamination control
3Object-affected harmful factors
If multiple discharging members and partition walls are added to create air circulation spaces, then foreign substances removal is enhanced, but the manufacturing complexity increases
Solution Approach 1:
The stage is segmented into multiple cell areas with partition walls that create discrete air circulation spaces. Each cell can be manufactured as a modular unit with integrated nozzles and suction ports, allowing for standardized production processes that reduce manufacturing complexity despite the increased number of components
Solution Approach 2:
The partition walls and air circulation channels are nested within the body member structure. The discharging members are positioned within the cell areas, creating a nested configuration where multiple functional elements are integrated into each other. This nesting reduces the overall footprint and simplifies assembly by eliminating the need for separate mounting structures
