Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing core drilling devices face challenges in performing dry drilling operations without water coolant, particularly in environments with hygiene requirements, such as hospitals or nursing homes, where water use is not permitted.
Innovation Solution
A suctioning cover for a core drill bit equipped with a pressure regulating valve that allows for the suctioning of material and generation of negative pressure to facilitate effective dry drilling by stabilizing the drill bit against the substrate and removing drill cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If water is used as coolant and flushing medium, then cooling and flushing functions are achieved, but water usage is required which is not permitted in hygiene-sensitive environments
Solution Approach 1:
The invention extracts the flushing function from water and implements it through a suction system. The suctioning cover with pressure regulating valve creates negative pressure to remove drill cuttings and dust from the borehole without requiring water as a flushing medium, thus eliminating water usage while maintaining cleaning effectiveness
Solution Approach 2:
The invention uses pneumatic principles by employing a suction system with pressure regulating valve to create negative pressure for removing drill debris. This replaces the hydraulic flushing method with water, achieving the same cleaning effect through air pressure differentials without water consumption
2Productivity
If pressure is increased to improve suctioning effectiveness, then material removal is enhanced, but user effort and device complexity increase
Solution Approach 1:
The pressure regulating valve is designed to automatically regulate and maintain optimal negative pressure in the suction system without requiring manual intervention. The system self-adjusts the pressure to ensure effective suctioning of drill cuttings while eliminating the need for user effort to manually control pressure, thus maintaining productivity while improving ease of operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables clean and efficient dry drilling by stabilizing the core drill bit and effectively removing drill cuttings, mimicking the cooling and flushing functions of water without water usage, while allowing for easy operation with reduced user effort.
Implementation Method 1
A negative pressure prevails in the interior of the core drill bit whilst work is performed using the core drilling device. Said negative pressure firstly ensures that the core drill bit is held firmly against the substrate to be machined.
Implementation Method 2
the suctioning cover (10) has a valve (12) for setting a pressure in the interior (58) of the core drill bit (50)... The pressure regulating valve is preferably configured to regulate or set the pressure in the interior of the core drill bit.
Implementation Method 3
Material for suctioning can thus be suctioned out of the interior of the core drill bit particularly effectively... Secondly, the negative pressure in the interior of the core drill bit generates a suction flow with which material for suctioning such as dust, drill cuttings or particles can be suctioned out of the borehole.
