Telescopic Snap-Fit Sump Basin for Confined Crawl Space Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sump basins face difficulties in installation within confined crawl spaces due to their size and the complexity of threading multi-segment basins, leading to increased costs and logistical challenges.
Innovation Solution
A telescopic snap-fit sump basin design with interfit portions that expand vertically by pulling up on the top segment, utilizing circumferential ribs and ledges for easy assembly and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a conventional one-piece sump basin is used, then the basin provides sufficient structural strength and stability, but it cannot fit into confined crawl spaces with only 15 inches of clearance
Solution Approach 1:
The sump basin is divided into multiple telescopic segments that can be collapsed into a compact configuration for easy installation through confined crawl spaces, then expanded to full size after installation. The segments include a first section with a first end and a second end, a second section telescopically received within the first section, and additional sections similarly arranged, allowing the basin to be disassembled into manageable pieces that fit through tight spaces while maintaining structural integrity when assembled.
2Length of moving object
If multi-segment sump basins are used to fit confined spaces, then the basin can be installed in tight crawl spaces, but threading the sections together becomes tedious and complicated due to debris and dirt
Solution Approach 1:
The telescopic segments are nested within each other in a telescopic arrangement where the second section is received within the first section, the third section within the second section, and so forth. This nesting configuration allows all segments to be collapsed into a compact package for installation, then expanded to full size after placement. The nested design eliminates the need for complex threading operations in dirty crawl spaces, as segments simply telescope apart along guide ribs.
Solution Approach 2:
The basin segments are designed with dynamic telescopic joints that allow movement between collapsed and expanded states. The segments include ledges and grooves that guide the telescopic motion, enabling easy expansion after installation without requiring complex threading or fastening operations in the confined, debris-filled crawl space environment.
3Adaptability or versatility
If multi-segment sump basins are threaded together in confined spaces, then the basin can be assembled, but the process is time-consuming and increases installation costs
Solution Approach 1:
The sump basin segments are pre-assembled into a telescopic configuration before installation, with all segments nested within each other in the correct sequence. This preliminary assembly allows the entire multi-segment basin to be installed as a single unit through the crawl space opening, eliminating the need for time-consuming on-site threading or fastening operations in the confined space. The segments are designed to telescope apart automatically or with minimal effort after placement.

AI summary
A sump basin is provided which is formed from telescopically interfit portions which can be snap-fit into an expanded position of increased vertical height by use of one or more ledges formed on circumferential ribs, merely by pulling up on the top segment once the collapsed basin is in place and a sump pump is mounted therein.
