Cover Window Incision Pattern for Autoclave Airflow Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cover windows for mobile electronic devices face challenges in preventing damage and contamination of holes formed during the manufacturing process, particularly during the autoclave process where hot air flows can cause twisting or lifting of protective members.
Innovation Solution
A cover window design incorporating a window member with a light transmitting and light shielding area, where the protective member is disposed on the surface and features an incision pattern that provides an air flow passage, preventing the twisting or lifting of protective members during hot air exposure and thus minimizing damage and contamination of holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective member is disposed on the cover window to protect holes during manufacturing, then the holes are protected from damage and contamination, but the protective member may twist or lift during autoclave process due to hot air flow
Solution Approach 1:
The patent extracts the harmful hot air flow from the autoclave process by creating an exhaust passage that channels the hot air away from the protective member. The exhaust passage extends from the first surface to the second surface of the protective member, allowing hot air to be discharged through the protective member itself rather than allowing it to accumulate and cause twisting or lifting.
Solution Approach 2:
The exhaust passage acts as an intermediary structure between the hot air flow and the protective member. It provides a controlled pathway for the hot air to pass through, preventing direct interaction between the hot air and the protective member that would cause deformation. The exhaust passage mediates the thermal environment to protect the protective member's stability.
2Adaptability or versatility
If holes are formed in the cover window for component functions, then the components can perform their functions, but the holes are vulnerable to damage and contamination during manufacturing process
Solution Approach 1:
The protective member is installed on the cover window before the autoclave process to preliminarily protect the holes from damage and contamination. The protective member covers the holes that have been formed for component functions, creating a protective barrier before the harsh autoclave conditions are applied.
Solution Approach 2:
The exhaust passage converts the harmful hot air flow into a beneficial controlled discharge mechanism. By providing a dedicated pathway for hot air ejection, the system uses the hot air flow itself to help maintain pressure equilibrium and prevent protective member deformation, turning a potential harm into a beneficial pressure management mechanism.

AI summary
A cover window includes a window member and a protective member. The window member includes a light transmitting area and a light shielding area. The protective member is disposed on a surface of the window member and includes an incision pattern. The light shielding area includes a trench portion extending concavely toward the light transmitting area. The protective member overlaps the trench portion in a thickness direction.
