Solution Overview

Problem

Existing drilling devices face challenges when operating in confined spaces, requiring significant conversion work to adapt to varying room widths and heights, which increases setup and drilling time.

Innovation Solution

A small, mobile drilling device with a telescopic mast that can be adjusted in length and pivoted about multiple axes, allowing for flexible positioning and operation without needing to move the device, enabling drilling in tight spaces and varying orientations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the drill mast length is fixed, then the device structure is simple, but it cannot adapt to different room heights and requires conversion work

Engineering Contradiction:
Improveadaptability to different spatial conditionsVSAvoiddevice structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The drill mast is designed as a telescopic structure with multiple sections that can be extended or retracted to different lengths. This dynamic adjustment capability allows the drilling device to adapt to various room heights and spatial conditions without requiring structural conversion work, resolving the contradiction between adaptability and device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The drill mast is divided into multiple telescopic sections that can be independently adjusted. This segmentation enables flexible length adjustment while maintaining a relatively compact base structure, allowing adaptation to different spatial conditions without proportionally increasing overall device complexity

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the drilling device is moved to drill holes close to walls, then drilling position flexibility is improved, but setup time increases

Engineering Contradiction:
Improvedrilling position flexibilityVSAvoidsetup time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The drill mast is equipped with multiple-axis pivoting mechanisms that enable dynamic positioning adjustments. The mast can be tilted about a first axis and rotated about a second axis, allowing the drilling device to reach holes close to walls without physically moving the entire device, thereby reducing setup time while maintaining drilling position flexibility

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The pivoting mechanism adds rotational degrees of freedom to the drill mast positioning system. By enabling rotation about a second axis in addition to tilting about the first axis, the system can access drilling positions in three-dimensional space without relocating the base device, eliminating the need for time-consuming repositioning

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If the mast is non-telescopic, then the device is simpler and more stable, but it requires conversion work to adapt to different heights

Engineering Contradiction:
Improveease of adaptation without conversion workVSAvoidmast structure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The mast is designed as a telescopic structure with movable sections that can be extended or retracted to achieve different lengths. This dynamic design enables easy adaptation to various heights without conversion work, while the telescopic mechanism itself integrates smoothly into the overall device structure, maintaining reasonable complexity levels

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The telescopic mast serves multiple functions: it provides the primary drilling support structure, enables height adjustment for different room conditions, and maintains structural stability. This multi-functionality eliminates the need for separate conversion components, achieving ease of adaptation without proportionally increasing device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
