Waste Line Insert for Narrow Wall Plumbing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern building design often faces challenges in accommodating horizontal waste lines in narrow wall spaces due to limited room, and existing solutions like the '493 patent require complex and time-consuming hole drilling for installation.
Innovation Solution
A waste line insert is provided that can be easily inserted into the upper and lower portions of an upright with set screws for securement, allowing a horizontal waste line to pass through, and optionally includes a bolt for additional rigidity, enabling flexible installation and angled waste line configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of holes need to be precisely drilled into an upright for waste line installation, then the waste line can be securely installed, but the installation time and complexity significantly increase
Solution Approach 1:
The device segments the waste line installation function from the upright structure by introducing a separate insert component. This insert contains pre-formed apertures for waste lines and is inserted into the upright, eliminating the need to drill holes directly into the upright. The segmentation allows the waste line routing function to be achieved through simple insertion rather than complex drilling operations.
Solution Approach 2:
The insert acts as an intermediary component between the upright and the waste line. Rather than directly drilling into the upright or installing waste lines without assistance, the insert serves as a mediator that provides the necessary apertures and structural support. This intermediary element simplifies the installation process while ensuring secure waste line routing.
2Reliability
If a plurality of holes need to be precisely drilled into an upright for waste line installation, then the waste line can be securely installed, but the installation complexity significantly increases
Solution Approach 1:
By segmenting the installation system into a separate insert component with pre-formed apertures, the complexity of precise hole drilling is transferred to the manufacturing stage rather than the installation stage. The insert is designed and manufactured with accurate apertures, then simply inserted into the upright, dramatically reducing installation complexity.
Solution Approach 2:
The necessary apertures for waste line installation are created in advance during the insert manufacturing process, rather than during installation. This preliminary action ensures precise aperture positioning and eliminates the need for complex drilling operations at the installation site, reducing both time and complexity.
3Area of stationary object
If fixture carriers are mounted within narrow wall space to minimize space, then wall space is efficiently utilized, but sufficient room for horizontal waste lines cannot be provided
Solution Approach 1:
The insert introduces a new dimension of waste line routing by creating apertures that allow horizontal waste lines to pass through the upright in narrow wall spaces. Rather than requiring lateral clearance that would increase wall space occupancy, the insert enables waste lines to traverse through the vertical structure, utilizing the third dimension (depth/thickness of the wall) instead of consuming lateral wall space.
Solution Approach 2:
The insert is nested within the upright structure, fitting into the internal cavity of the upright without requiring additional external wall space. This nesting arrangement allows the waste line routing function to be integrated within the existing upright geometry, maintaining compact wall space utilization while providing necessary plumbing functionality.
