Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for bending electrical metallic tubing (EMT) conduits often result in costly wastage due to suboptimal bending, as professionals may need to attempt bending multiple conduits before achieving the desired shape, highlighting a need for a testing tool that allows for precise measurement and angle simulation before permanent bending.
Innovation Solution
A conduit tube bending tester featuring a bendable wire core and a resilient outer body with measurement markings, allowing for flexible bending and retention of shapes, and mimicking the size and shape of conventional EMT tubing for accurate testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If professionals bend EMT conduits directly for permanent installation, then the installation process is straightforward, but costly wastage occurs due to suboptimal bending requiring multiple conduit attempts
Solution Approach 1:
The patent creates a bendable tubular apparatus that replicates the physical properties, dimensions, and flexibility of actual EMT conduits. This copy allows professionals to test and verify bending parameters before working with expensive permanent conduits, eliminating wastage while maintaining operational simplicity
Solution Approach 2:
The apparatus enables preliminary testing of bending angles, measurements, and placements before permanent conduit installation. By performing the bending test in advance on a reusable mockup, professionals can optimize the bending parameters and avoid costly mistakes during actual installation
2Ease of operation
If a bendable tubular apparatus is made completely flexible for easy bending, then it allows repeated bending attempts, but it loses the ability to retain bends for accurate measurement testing
Solution Approach 1:
The apparatus combines a resilient outer body material that provides flexibility for bending with an internal wire core structure that provides shape retention. This composite construction allows the tube to be bent easily yet maintain the bent shape for accurate measurement and angle verification
Solution Approach 2:
Different parts of the apparatus have different mechanical properties: the outer body provides flexibility and cushioning, while the internal wire core provides structural support and shape memory. This local differentiation of material properties resolves the contradiction between ease of bending and bend retention
3Measurement precision
If measurement markings are added to the exterior surface of the tubular apparatus, then precise measurements of spaces and distances are enabled, but the manufacturing complexity increases
Solution Approach 1:
The measurement markings are incorporated into the mold used to create the tubular apparatus, allowing precise measurement indicators to be added during the manufacturing process without requiring complex post-processing or assembly steps
Solution Approach 2:
The measurement marking function is merged with the outer body structure itself. The markings are integrated directly into the resilient material during molding, combining the structural and measurement functions into a single component rather than adding separate measurement devices
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 efficient and cost-effective testing of conduit measurements, angles, and placements, reducing wastage by allowing professionals to simulate and optimize EMT conduit bending before permanent installation, thereby improving the effectiveness of electrical installations.
Implementation Method 1
The outer body may additionally include a plurality of markings which define standardized measurements. Being embodied as a wire, the core member has the ability to be bent at any point along its length in any direction through the application of external force and retain the bend unless and until it is straightened or re-bent in another direction through application of external force.
