Shaped Glass Covers With Relief Patterns For Electronic Devices

The patent applies preliminary action by first forming a relief pattern on the glass sheet that corresponds to the desired opening locations and shapes, before actually removing material to create the openings. The relief portions are formed in advance as guide structures that define where openings should be created, enabling efficient subsequent processing.

The patent uses the relief portions as intermediary structures that mediate between the design specification for openings and the final opening configuration. These relief portions serve as temporary guide structures that facilitate the formation of multiple openings of different sizes and shapes by providing a pre-established pattern that guides the opening formation process.

The patent merges multiple processing operations into a single integrated process. By forming the relief pattern and subsequent openings in a coordinated sequence rather than as separate serial operations, the method reduces total processing time and improves production efficiency. The relief portions and openings are created in an integrated workflow rather than through multiple discrete steps.

The patent maintains continuity of useful action by ensuring that the formation of relief portions and subsequent openings occurs in a continuous, coordinated process without unnecessary interruptions or idle time. The methodology enables seamless transition from relief formation to opening creation, maximizing the utilization of processing equipment and minimizing downtime between operations.
