Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in the manufacturing of display devices is the contamination material produced during the substrate cutting process, which affects the efficiency and reliability of the cutting process and the quality of the display modules.
Innovation Solution
A substrate cutting device is designed with a base portion, stage, partition member, and exhausting structure to effectively remove contamination material by creating an airflow that exhausts gaseous substances away from the cutting area, utilizing suction openings and inclined patterns to secure and separate the substrate, and overlapping exhausting structures to enhance airflow and reduce contamination accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If substrate cutting is performed without an exhausting structure, then the cutting process can be carried out, but contamination material accumulates and affects cutting efficiency and display module quality
Solution Approach 1:
The patent extracts and removes the harmful gaseous substances and contamination materials generated during substrate cutting through an exhausting structure. The exhaust openings in the stage and partition members, combined with suction force, extract contaminated air and particles from the cutting area, preventing accumulation and maintaining cutting efficiency and display module quality.
Solution Approach 2:
The patent employs pneumatic principles by using airflow generated through exhaust openings and suction force to remove contamination. The exhausting structure creates controlled air flow that carries away gaseous substances and particles from the cutting zone, utilizing gas dynamics to solve the contamination problem.
2Productivity
If an exhausting structure is added to remove contamination, then cutting efficiency improves, but device complexity increases
Solution Approach 1:
The patent merges the exhausting function with the existing structural components (stage and partition members). The exhaust openings are integrated into these components rather than being separate additions, and the partition members serve both structural support and exhaust channel functions, reducing overall device complexity while maintaining effectiveness.
Solution Approach 2:
The partition members serve multiple functions: they provide structural support, define cutting paths, guide substrates, and act as exhaust channels. The stage also serves dual purposes as both a support platform and an exhaust structure with integrated openings. This multi-functionality reduces the need for separate dedicated exhaust components.
3Manufacturing precision
If multiple partition members are used to guide substrate, then cutting precision improves, but device complexity increases
Solution Approach 1:
Each partition member is designed to perform multiple functions: guiding the substrate along the cutting path, providing structural support, and serving as an exhaust channel through integrated exhaust openings. This multi-functionality allows the use of multiple partition members for precision guidance without proportionally increasing complexity, as each component contributes to multiple system requirements.
