Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for removing plugging from pipes using impact tools can generate sparks, leading to fires or explosions when combustible gases or liquids are present, posing a risk of accidents.
Innovation Solution
A drilling apparatus with a bronze drill bit, up-and-down adjustment handle, and a screw mechanism, housed in a body casing with a head cover for collecting debris, and a flexible pressure hose for easy access in narrow spaces, designed to crush and safely remove plugging without sparking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional impact tools such as welding rod are used to remove plugging, then plugging removal is achieved, but sparks are generated causing fire hazard when combustible gas or liquid is present
Solution Approach 1:
The patent replaces the conventional impact-based mechanical removal system with a drilling system that uses rotational cutting action. The drill bit with cutting edges rotates to grind and remove plugging, substituting the impact mechanism with a controlled rotational mechanical system that does not generate sparks
Solution Approach 2:
The patent changes the operational parameters from high-impact force to controlled rotational speed and cutting feed rate. By adjusting the rotation speed of the drill bit and the feed rate of the drilling apparatus, the system achieves effective plugging removal through gradual cutting rather than sudden impact, eliminating spark generation
2Object-affected harmful factors
If drill bit is used to crush plugging, then fire hazard is eliminated, but device structure becomes more complex
Solution Approach 1:
The drilling apparatus is designed to perform multiple functions: the drill bit not only removes plugging but can also create holes for inserting other cleaning tools or chemicals. The apparatus can be adapted to different pipe sizes and plugging types by changing drill bits or adjustment settings, reducing the need for multiple specialized tools
Solution Approach 2:
The drilling apparatus features a compact nested structure where the drill shaft, drill bit, and adjustment mechanisms are housed within a telescopic or collapsible frame. The internal components are arranged concentrically, with the drill bit at the center, surrounded by the drill shaft, which is nested within the adjustment mechanism housing, creating a space-efficient design
3Manufacturing precision
If up-and-down adjustment mechanism is added to control drill bit movement, then drilling precision is improved, but device complexity increases
Solution Approach 1:
The adjustment mechanism incorporates self-locking features where the threading automatically locks the drill bit at the desired depth without requiring additional locking components. The spring-loaded adjustment system automatically returns the drill bit to its starting position after each drilling stroke, eliminating the need for manual repositioning mechanisms
