Hollow-Core Slab Drainage Tray for Controlled Water and Dust Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Draining water from hollow-core slabs during construction or maintenance often results in uncontrolled water flow, causing damage and reducing drill lifespan due to concrete dust contamination.
Innovation Solution
A tray with a base and sides to collect water, featuring a collar to prevent water from escaping during drilling, and anti-rotation means for stability, supported by the drill to guide water out in a controlled manner, preventing dust spread and ensuring the tray remains in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If drilling is carried out to drain water from hollow-core slabs, then water can be removed from cavities, but water gushes out uncontrolled and runs over the driller and drilling device
Solution Approach 1:
A tray is introduced as an intermediary device between the drilling operation and the water flow path. The tray collects water draining from the cavity through the drill hole and channels it through a controlled outlet away from the operator and drilling equipment, preventing uncontrolled water flow while maintaining effective water removal
Solution Approach 2:
The harmful uncontrolled water flow is extracted and separated from the drilling operation by using the tray to intercept and redirect the water. The tray's collection volume and guided outlet extract the water flow from the harmful uncontrolled path and redirect it along a controlled trajectory
2Quantity of substance
If drilling is carried out in an already finished building, then cavities can be drained, but water flowing out causes damage when it spreads to the floors
Solution Approach 1:
The tray serves as an intermediary that captures water at the source (drill hole) and provides a controlled discharge path that directs water away from vulnerable areas such as floors. This prevents water from spreading uncontrollably and causing damage to finished building surfaces
Solution Approach 2:
The tray is positioned and ready before drilling begins, with its collection volume and outlet already in place to intercept and redirect water flow. This preliminary preparation ensures that when water starts draining during drilling, it is immediately captured and directed away from areas that could be damaged
3Productivity
If drilling is carried out without protection, then cavities can be punctured, but concrete dust falls on the driller and drill, reducing service life
Solution Approach 1:
The tray acts as an intermediary barrier between the drilling operation and the environment. It captures not only water but also concrete dust generated during drilling, preventing dust from falling on the operator and drilling equipment, thereby extending service life while maintaining productivity
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
The tray effectively collects and directs water away from the operator and drill, reducing damage and extending drill life by containing water and dust, facilitating controlled drainage and recovery.
Implementation Method 1
The tray is configured to be supported at least in part on the drill bit or the drill or both during drilling... allows the water that is removed by gravity through the hole drilled into the cavities to be received in a controlled manner
Implementation Method 2
a collar configured to surround the second opening, which collar extends from the base in the direction of drilling and is configured to prevent, at least for the most part, water from leaving the tray via the second opening when the drill bit runs through the second opening
