Solution Overview

Problem

Existing catch basins have fixedly positioned outlets and inlets, making installation and alignment with piping systems difficult and prone to damage, lacking flexibility in placement adjustments.

Innovation Solution

A catch basin with slide openings and removable slide members that allow for adjustable positioning of outlets and inlets along the sidewalls, enabling easy alignment with piping systems without the need for tools and reducing the risk of damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If outlets and inlets are fixedly positioned on catch basin sidewalls, then manufacturing and structural integrity are simplified, but installation flexibility and alignment with piping systems deteriorate

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sidewall is segmented into multiple sections with slide openings at different positions. Slide members can be selectively positioned at different segments along the sidewall, allowing flexible selection of outlet/inlet positions while maintaining a relatively simple overall basin structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outlet and inlet positions are made dynamic rather than fixed. Slide members can move along the sidewall and be positioned at different locations, enabling adaptation to various piping system configurations without requiring a completely different basin design.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If outlets and inlets are fixedly positioned, then manufacturing process is simplified, but alignment with piping systems during installation becomes difficult

Engineering Contradiction:
Improvealignment easeVSAvoidmanufacturing simplicity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

Multiple slide openings are pre-positioned at standard locations along the sidewall during manufacturing. This preliminary preparation allows installers to simply select and position slide members at the appropriate pre-marked locations, eliminating the need for complex field measurements and adjustments.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If fixed positioning is used, then device structure is simpler, but installation time and potential for damage increase

Engineering Contradiction:
Improveinstallation speedVSAvoidpositioning mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The slide members are designed to be self-positioning within the slide openings. The friction-fit mechanism allows the slide member to automatically find its correct position and lock in place without requiring additional tools or complex alignment procedures, enabling quick installation by the installer themselves.

Inventive Principle:
Principle #25Self-service

AI summary

A catch basin configured to allow selective positioning of the outlet and inlet ports on the side walls of the catch basin's receptacle body. At least one of the receptacle side walls comprise a slide opening having opposing sides. A slide member has a pair of slide edges that slidably engage the sides of the slide opening to substantially close the slide opening. The slide member has a port section and two or more positioning sections, with at least one positioning section located above the port section and one below the port section. The port section has an outlet or inlet port integral therewith or fixedly attached thereto or the port section comprises a mechanism for attaching an outlet or inlet port thereto, such as a port cutout having a removable knockout plate. The slide member has section removal indicators to identify which positioning sections should be removed.
