Problem
Current methods for copying drill holes in assembly processes are inefficient, prone to human error, and require laborious measurement operations, especially for inaccessible or blind holes, leading to increased assembly time and material waste.
Innovation Solution
A drill-and-hole detector tool comprising two plates with passing holes and studs, a drilling chimney, and a positioning rivet, allowing precise copying of drill holes without moving unnecessary parts, adaptable to various diameters and surface geometries, and easily constructible in workshops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional measurement methods are used to copy drill holes, then the task can be completed, but the process is tedious and prone to human error
Solution Approach 1:
The patent uses a plastic template that physically copies the drill hole pattern from the original support structure. The template is placed over the original structure, and drill holes are transferred through the template to the new piece, eliminating manual measurement and calculation while ensuring precise replication of the original hole positions.
Solution Approach 2:
The plastic template serves as an intermediary device between the original support structure and the new piece. It captures the drill hole positions from the original structure and transfers them accurately to the new piece, acting as a mediator that eliminates direct measurement operations.
2Ease of operation
If plastic templates are used to copy drill holes, then positioning can be facilitated, but innumerable errors occur in copying and positioning operations
Solution Approach 1:
The template is designed as a direct physical copy of the original support structure's drill hole pattern. By replicating the exact positions and configurations of the original holes in the template, the system ensures that transferring holes to the new piece is both easy and accurate, eliminating positioning errors.
3Measurement precision
If complete removal of structure is carried out to access blind drill holes, then measurement becomes possible, but laborious operations and time are required
Solution Approach 1:
The template is prepared in advance with all drill hole positions pre-marked and configured according to the original support structure. This preliminary preparation eliminates the need for complex on-site measurements and operations, allowing direct transfer of hole positions even for blind or inaccessible holes.
4Productivity
If traditional measurement systems are used, then drill holes can be copied, but the human error factor increases and pieces may be discarded
Solution Approach 1:
The template provides a physical copy of the drill hole pattern that eliminates manual measurement and calculation, the primary sources of human error. By directly transferring hole positions through the template, the system ensures high reliability and prevents pieces from being discarded due to positioning errors.
