Magnetic Corner Block for Builder's Line Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing builder's profiling tools, such as string lines held by corner blocks, are prone to movement and dislodgment due to friction forces, which can lead to instability and safety issues on construction sites, especially in high-traffic areas and when working alone.
Innovation Solution
A corner block with a magnetic attachment system that secures to posts using rare earth magnets, providing additional stability and allowing for easier repositioning without slacking the string line, and enabling solo installation by reducing the need for manual friction-based adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If corner blocks are held in place by friction forces from tightened string, then the string can be securely attached, but the corner blocks are prone to movement and dislodgment
Solution Approach 1:
The patent replaces the friction-based mechanical attachment system with a magnetic attachment system. The magnet embedded in the corner block interacts with the magnetic post to provide secure holding force, eliminating reliance on friction from tightened string. This substitution maintains secure attachment while enabling easier repositioning through simple magnetic attraction and release.
2Productivity
If corner blocks are frequently dislodged in heavy-traffic areas, then repositioning is needed, but the whole arrangement must be reset
Solution Approach 1:
The magnetic attachment system allows corner blocks to be quickly repositioned by simply moving them along the magnetic post without slackening or resetting the string line. The magnetic force maintains stability during normal use while enabling rapid repositioning in response to traffic conditions, eliminating the need for complete reset procedures.
3Manufacturing precision
If the string is moved from level due to slight corner block movement, then the builder might not notice, but the profile accuracy is compromised
Solution Approach 1:
The magnetic attachment system prevents even slight movements of the corner blocks along the post, thereby maintaining the string line at the correct level. The magnetic force provides consistent holding pressure that prevents accidental displacement, ensuring both accuracy and detectability of the profile level.

Function Achieved in This Case
The magnetic corner block enhances stability, reduces the risk of accidents by preventing falls, and saves time by allowing for smoother and safer repositioning of the builder's line, especially in heavy-traffic construction environments and when working alone.
Implementation Method 1
a magnet mounted in the body so as to be associated with at least one of the pair of gripping faces, wherein the magnet has a magnetic force sufficient to attract it to the material of the post to which the gripping faces are applied in use
