Solution Overview
Problem
Basement waterproofing systems face challenges with groundwater seepage through concrete foundations, leading to structural damage and harmful bacteria growth, as traditional sump systems are inefficient in collecting and managing moisture effectively.
Innovation Solution
A redesigned sump liner system with a rectangular geometry, integral pump stand, adjustable inlet, and detachable lid, featuring apertures for groundwater collection and a slidable cover for customizable alignment, enhances the collection and discharge of groundwater, preventing structural damage and bacterial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional circular sump liners are used, then they provide basic groundwater collection, but they are inefficient in collecting and managing moisture effectively
Solution Approach 1:
The sump liner is divided into multiple functional zones: an upper collection zone with apertures for groundwater intake, a middle separation zone with gravel layer and geotextile fabric, and a lower discharge zone. This segmentation improves groundwater collection efficiency by optimizing each zone's function while managing moisture flow systematically.
Solution Approach 2:
Different regions of the sump liner are assigned different properties: the upper portion has apertures for water intake, the middle section contains coarse gravel and geotextile fabric for filtration and sedimentation, and the lower portion provides discharge functionality. This local differentiation of properties enhances overall groundwater management efficiency.
2Adaptability or versatility
If traditional sump liners with fixed design are used, then they are simple to install, but they cannot accommodate various foundation configurations
Solution Approach 1:
The sump liner incorporates adjustable and removable components, including a detachable lid with adjustable positioning and a flexible gravel layer that can be adapted to different foundation contours. This dynamic design allows the same sump liner structure to accommodate various foundation configurations while maintaining installation simplicity.
Solution Approach 2:
The sump liner is designed as a universal system that can function with different foundation types and configurations. The adjustable lid and flexible internal components allow it to adapt to various basement layouts and foundation geometries, making it a multi-functional solution applicable to diverse building structures.
3Reliability
If traditional sump liners without filtration features are used, then they are simple in structure, but they allow sediment and debris to interfere with sump pump operation
Solution Approach 1:
A geotextile fabric layer is introduced as an intermediary between the gravel layer and the sump pump discharge area. This fabric acts as a filter that allows water to pass through while blocking sediment and debris, thereby protecting the sump pump from interference without significantly complicating the overall structure.
Solution Approach 2:
Coarse gravel and geotextile fabric with controlled porosity are used to create a filtration system. The porous structure allows groundwater to permeate through while trapping sediment and debris particles, ensuring reliable sump pump operation by preventing clogging and mechanical interference.
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
The improved sump liner system effectively collects and discharges groundwater, reducing structural damage and bacterial growth, while its adjustable design accommodates various foundation configurations, ensuring efficient basement waterproofing.
Implementation Method 1
water may accumulate around the foundation as the groundwater level periodically rises, for example, due to rain or melting snow. As a result, hydrostatic pressure may build causing leakage at cracks in the footings
Implementation Method 2
Concrete, typically used in the construction of foundations, attracts groundwater by sorption
Implementation Method 3
capillary forces in the concrete pores facilitate further penetration of the groundwater

AI summary
A sump system for use in basement waterproofing systems. A sump liner may be generally rectangular in geometry, and may include two side elements with apertures to exchange groundwater while blocking debris. An adjustable inlet may be provided in another side element to fluidly connect other elements of a basement waterproofing system to the sump liner. The sump liner may further include a base configured to provide a built-in stand for a sump pump. The pump stand may contain a lip with notches to allow debris to fall and collect in a trough around a periphery of the base. The base may further provide an underside cavity for accommodating an obstruction in the floor of a sump hole. A removable lid may facilitate access to the sump liner interior, and may contain a break-away feature to accommodate discharge piping, as well as a groove to lodge a pump power cord. The sump liner may be strategically oriented within the sump hole to protect the basement foundation from erosion.
