Stationary Drill Array for Customized Sound-Absorbing Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of sound-absorbing panels is complex, time-consuming, and costly due to the traditional method of drilling holes in panels, which limits customization and increases manufacturing costs.
Innovation Solution
A method involving a stationary drill field with rotating drills of different diameters, where the panel is moved relative to the drill field to efficiently create holes and cavities on both sides, allowing for faster production and increased design flexibility by minimizing the number of work processes and avoiding adhesive-related issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional drilling methods are used to create holes in panels, then holes can be produced, but the production process becomes complex and time-consuming
Solution Approach 1:
Instead of moving the drill field vertically downwards towards the table with the panel, the patent inverts the approach by keeping the drill field stationary and moving the table with the panel horizontally through the drill field. This inversion simplifies the drilling mechanism while maintaining hole production capability.
Solution Approach 2:
The patent employs dynamic movement of the table carrying the panel through the stationary drill field, allowing continuous drilling operation. The table can be moved horizontally to position different areas of the panel under the drills, enabling efficient production without complex vertical drilling mechanisms.
2Adaptability or versatility
If multiple drilling operations are performed to create customized hole patterns, then design flexibility is achieved, but manufacturing time and costs increase
Solution Approach 1:
The drill field is segmented into multiple independently controllable drills arranged in a grid pattern, allowing selective activation of specific drills to create customized hole patterns. This segmentation enables diverse designs to be produced in a single continuous drilling operation rather than multiple sequential operations.
Solution Approach 2:
The patent maintains continuous drilling action by moving the panel through the stationary drill field in a single pass. The controlled horizontal movement of the table ensures that holes are drilled continuously at the required positions without stopping for repositioning or reconfiguration, reducing manufacturing time while maintaining customization capability.

AI summary
The sound-absorbing panel manufacturing device (8) has a table (3) and a drill area (4) with multiple drills. The table is moved relative to the drills in a direction (y) perpendicular to the level of drill area. The table has a fitted plate (2), and is moved relative to the drill area, such that rotating drill fully penetrates coating. Penetration depth of the rotary drill corresponds to thickness of the coating and thickness of carrier plate.
