Break-Off Threaded Pipe Section for Flush Wall Plate Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for shortening threaded pipe sections in wall panels during installation are prone to damaging new tiles and create additional sealing points, as they require cutting, which can lead to metal chips and uneven surfaces.
Innovation Solution
A wall panel design with a predetermined breaking point, featuring internal or external grooves that allow for non-cutting length adjustment, combined with a tool using axially displaceable threaded rods to separate the pipe section at a defined breaking point, eliminating the need for tap extensions and minimizing tile damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a countersink cutter is used to shorten the pipe section during final installation, then the threaded connection can be adjusted to sit flush with the wall, but metal shavings are generated and there is a high risk of damaging new tiles
Solution Approach 1:
The patent applies preliminary action by forming breaking points (grooves) in the pipe section during manufacturing, before installation. This allows the pipe to be broken at predetermined locations without cutting during final installation, eliminating the need for countersink cutters that generate metal shavings and risk damaging tiles. The breaking points are strategically positioned to enable flush installation while avoiding harmful cutting operations during the final installation phase.
2Ease of manufacture
If tap extensions are used to extend the threaded connection, then the wall plate can be installed without cutting, but additional sealing points are created that are not visible or inspectable
Solution Approach 1:
The patent applies the taking out principle by removing the need for tap extensions entirely. Instead of adding extensions to the threaded connection, the invention breaks the pipe section at predetermined breaking points to achieve the required length. This eliminates the additional sealing points that would be created by tap extensions, while still allowing simple installation without cutting operations.
3Adaptability or versatility
If a large number of different length tap extensions are kept on hand, then the right extension can be selected for each installation, but inventory complexity and selection time increase
Solution Approach 1:
The patent applies parameter changes by incorporating multiple breaking points at different positions along the pipe section during manufacturing. This allows the pipe to be broken at various predetermined locations to achieve different lengths, eliminating the need for multiple tap extensions of different lengths. The breaking points are positioned to provide the necessary length variations while simplifying inventory management and reducing selection time during installation.
