Universal Connector Member Layout for Safer Hole Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal connectors face challenges in mechanical processing due to difficult drilling processes that can damage equipment, and they suffer from insufficient structural strength due to thin thickness between insertion holes and lateral surfaces.
Innovation Solution
The universal connector features a connecting member with strategically positioned insertion holes that are drilled from opposite ends, avoiding interference with other structures and allowing for a sufficient thickness between holes and lateral surfaces, thus enhancing mechanical processing convenience and structural strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the inserting hole is drilled close to the side surface of the accommodating recess, then the universal connector can be assembled, but the drill bit is easily damaged or destroys the structure of the connecting member
Solution Approach 1:
The patent introduces a new spatial dimension by adding a top surface and bottom surface to the connecting member, drilling insertion holes from these surfaces rather than from lateral surfaces near accommodating recesses. This dimensional shift allows holes to be positioned far from critical structures, eliminating drill bit damage risks while maintaining assembly functionality.
2Ease of manufacture
If the inserting groove is positioned closer to the through hole, then drilling interference is prevented, but the thickness of the connecting member becomes very thin, adversely affecting structural strength
Solution Approach 1:
The patent resolves this contradiction by transitioning from lateral surface drilling to top/bottom surface drilling. This dimensional change allows both the insertion holes and accommodating recesses to be positioned optimally without creating thin walls, as holes drilled from opposite ends naturally maintain sufficient material thickness between them.
3Ease of operation
If the insertion hole is drilled from the lateral surface, then the restoring member can be inserted, but the drill bit passes along the side surface of the accommodating recess causing damage
Solution Approach 1:
The patent extracts the harmful interaction between the drill bit and accommodating recess by separating their spatial locations. Insertion holes are drilled from top/bottom surfaces at positions far from accommodating recesses, which remain accessible from lateral surfaces, thus eliminating drill bit damage while preserving restoring member insertion functionality.

AI summary
A connecting member of a universal connector includes a first insertion hole and a second insertion hole formed on from a first end surface toward a second end surface of the connecting member, and a third insertion hole and a fourth insertion hole formed on the second end surface toward the first end surface of the connecting member, whereby the insertion holes will not be affected by and damage other structures of the connecting member in the mechanical process, so as to achieve the enhancement of the convenience of processing.
