Solution Overview

Problem

The manual process of changing straight flute drill bits in deep hole drilling machines is time-consuming and requires operator attendance, leading to prolonged machine shutdowns and limited operational hours.

Innovation Solution

A device with a magazine for multiple drill bit supporting sliders and a movable arm for automatic loading and positioning of sliders at a multifunctional machine head, enabling automatic drill bit changes without operator intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual drill bit changing is used, then the machine structure remains simple, but machine shutdown time increases and productivity decreases

Engineering Contradiction:

Improvemachine operational hoursVSAvoiddrill bit changing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The drill bit changing system is segmented into multiple independent sliders, each capable of holding a drill bit. The magazine contains multiple sliders that can be independently selected and transferred to the head, eliminating the need for manual intervention and reducing changing time.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple drill bits are pre-loaded onto sliders and stored in the magazine before machining operations begin. This preliminary preparation allows for rapid drill bit changes during operation without requiring operator attendance or machine shutdown.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If automatic drill bit changing is implemented, then productivity increases, but device complexity increases

Engineering Contradiction:

Improveautomatic operation capabilityVSAvoidmagazine and slider system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system is designed to automatically select, transfer, and install drill bits from the magazine to the head without operator intervention. The movable arm autonomously performs the transfer operation, and the head's coupling means automatically secures the slider, enabling 24-hour operation without attendance.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The head is designed with universal coupling means that can accommodate multiple sliders with different drill bits. This multi-functionality allows the same head structure to work with various drill bit types and configurations, reducing overall system complexity despite the automatic changing capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Speed

If multiple sliders are stored in a magazine, then drill bit changing speed increases, but the machine head structure becomes more complex

Engineering Contradiction:

Improvedrill bit changing speedVSAvoidhead coupling means

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The movable arm acts as an intermediary mechanism between the magazine and the head. It automatically transfers sliders from the magazine to the head's coupling means, enabling rapid drill bit changes while keeping the head structure relatively simple through automated mediation rather than complex manual interfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)
