Earth Boring Device With Radially Accessible End Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earth drilling devices require complex and time-consuming processes to change attachment options due to screwing and gluing, which is inefficient and time-consuming, especially under harsh ground conditions.
Innovation Solution
The earth drilling device is designed with an opening or connection pair at the end of the housing, allowing for simpler and faster attachment of optional connection options, such as direct piping, by providing a radially accessible connection and using a flexible connecting element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw connection and gluing are used to attach attachment options, then secure design is achieved, but conversion becomes complex and time-consuming
Solution Approach 1:
The housing is divided into a main body and a separable end portion that can be quickly attached or removed. The end portion can be exchanged without complex operations, allowing different attachment options to be changed simply by replacing the end portion rather than performing screwing and gluing operations each time.
Solution Approach 2:
The end portion is pre-designed with integrated attachment features and pre-configured for specific applications. This preliminary preparation allows for rapid exchange of different end portions based on application requirements without needing to perform complex assembly operations during conversion.

3Ease of operation
If an opening is provided at the end of the housing, then simpler and faster attachment is enabled, but material weakening and soil penetration risk increase
Solution Approach 1:
The opening is strategically positioned and dimensioned to provide access for attachment operations while preserving the overall structural integrity of the housing. The local geometry around the opening is optimized to minimize material weakening and prevent soil penetration, allowing simple attachment without compromising reliability.
