Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling machines face challenges in efficiently drilling complex structures of aircraft parts without a simpler structure, as they require multiple drilling tools and precise positioning, which complicates the drilling process and increases manufacturing costs.
Innovation Solution
A self-propelled automatic drilling machine with multiple drilling structures, IC tag readers, and a controlling device that uses IC tags attached to drilling plates to automatically control the drilling process, allowing for the attachment of different drilling tools and simplifying the structure by using the object itself as a guide for the traveling mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple drilling tools are used to drill holes of different diameters, then drilling versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements a drilling tool magazine that can store multiple drilling tools with different diameters, allowing a single drilling machine to perform multiple drilling operations with various hole sizes. The magazine system enables the drilling head to automatically select and switch between different drilling tools based on the processing requirements, achieving multi-functionality without requiring separate drilling machines for each diameter.
2Measurement precision
If a self-travelling drilling machine with light recognition is used, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The patent introduces a positioning device that attaches to the workpiece and stores identifier information corresponding to process parameters such as hole position and diameter. The reader on the drilling machine reads this identifier information to determine drilling parameters, serving as an intermediary between the workpiece and the control system. This approach simplifies the positioning system compared to complex light recognition while maintaining accuracy through the standardized positioning device.
3Stability of the object's composition
If dedicated rails are used for traveling mechanism, then positioning stability is improved, but device complexity and weight increase
Solution Approach 1:
The patent utilizes the workpiece itself as the guide rail for the traveling mechanism. The traveling structure moves along predetermined paths defined by the workpiece geometry or attached positioning elements, eliminating the need for separate dedicated rails. This self-service approach reduces device complexity and weight while maintaining positioning stability through the inherent structural features of the workpiece.
