Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plumb bobs with integrated laser devices are impractical and imprecise for aligning core drilling machines, especially when producing aligned bores for risers, as they lack efficient attachment mechanisms and precision in aligning vertical openings.
Innovation Solution
A plumb bob with a holding device featuring a recess and internal thread for easy attachment to the core drilling machine's shaft, combined with a laser device that indicates drilling centers, allowing for precise alignment of vertical openings by projecting a laser beam through drilled breakthroughs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a plumb bob with integrated laser device is used for aligning core drilling machines, then the line of sound can be shortened and wind resistance is reduced, but the attachment mechanism is impractical and alignment precision is insufficient
Solution Approach 1:
The patent replaces the traditional mechanical plumb line alignment system with an optical laser alignment system. The laser device projects a visible beam that serves as the alignment reference, eliminating the need for long physical plumb lines and providing precise visual guidance for drill hole alignment while reducing wind resistance effects.
Solution Approach 2:
The patent introduces a laser beam as an intermediary element between the plumb bob and the target alignment point. This laser intermediary provides a visible, precise alignment reference that can be seen over distances, solving the problem of insufficient alignment precision while maintaining the shortened plumb line configuration.
2Productivity
If a plumb bob with integrated laser device is used, then the plumb line can be shortened to reduce wind attack surface area, but the attachment to core drilling machine is impractical
Solution Approach 1:
The holding device is designed with a universal attachment mechanism that can securely mount to various core drilling machine shaft configurations. The threaded connection system provides a standardized interface that enables easy attachment and detachment, making the plumb bob versatile for different drilling equipment while maintaining quick setup capability.
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 quick, precise, and time-efficient creation of vertically aligned floor or ceiling openings with reduced wind resistance, ensuring accurate alignment of risers and wall openings.
Implementation Method 1
The plumb line (11) comprises a holding device (21), which is connected to the pendulum device (17)... The laser device (15) is directed downwards in the hanging direction of the plumb line (11), so that the laser beam, as an extension of the plumb line, is aligned with it and exits from the plumb line tip.
Implementation Method 2
plumb bobs with a plumb line and a line of sound are known from technology... The laser device is housed in the plumb line. The laser device is directed downwards in the hanging direction of the plumb line
