Curved Sidewall Window Well with Integrated Ladder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current window wells face issues with vertical load problems due to their weight, lack of structural rigidity, and inability to be stacked, and they do not allow for easy soil uplift during soil-uplifting conditions.
Innovation Solution
The development of lightweight, durable, one-piece window wells with a curved sidewall and integrated ladder, featuring a unitary construction, air gap space, and horizontally oriented members for structural rigidity, which are stackable and have an open bottom for soil uplift, made from materials like aluminum and polyolefins using processes like blow molding or 3D printing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional window wells are constructed with heavy materials for structural strength, then strength is improved, but weight increases causing vertical load problems
Solution Approach 1:
The window well employs a curved sidewall design instead of traditional straight vertical walls. This curvature distributes soil and water loads more efficiently around the structure, providing enhanced structural strength while using lighter materials. The curved geometry naturally resists lateral earth pressure, allowing the window well to maintain integrity without requiring heavy construction materials.
Solution Approach 2:
The invention utilizes composite material construction, combining materials with different properties to achieve both light weight and high strength. The system integrates components made from materials such as polyethylene, polypropylene, or other polymers that offer high strength-to-weight ratios, allowing the window well to be lightweight yet structurally robust enough to withstand soil and water loads.
2Ease of manufacture
If window wells are designed as single-piece construction for simplicity, then ease of manufacture is improved, but adaptability to different configurations is reduced
Solution Approach 1:
The window well system is divided into multiple stackable modules, each being a complete functional unit with integrated components. These modules can be vertically stacked to create window wells of various depths and configurations. Each module maintains structural integrity as a single piece while enabling flexible assembly through standardized connection interfaces, allowing adaptation to different site requirements and egress needs.
3Strength
If window wells have closed bottom construction for structural integrity, then strength is improved, but soil uplift during soil-uplifting conditions is restricted
Solution Approach 1:
The window well bottom is designed with dynamic characteristics that allow it to flex and move with soil expansion and contraction forces. Rather than being a rigid closed structure, the bottom construction can deform elastically during soil-uplifting conditions, dissipating forces and preventing structural damage while still maintaining overall integrity during normal service conditions.

AI summary
A window well is disclosed. The window well has a curved wall that has an inner wall section, an upper wall section, and a base. The upper wall section is unitary with the inner wall section. The curved wall includes an outer wall section unitary with the upper wall section. Between the inner and outer wall sections is an air space. The curved wall further includes at two horizontally oriented members or footholds that are unitary with, and that extend inwardly toward the center of curvature of, the curved wall, and which are spaced above the base. Each foothold includes a spaced-apart pair of handholds dimensioned, configured, and oriented to enable a user to extend an adult palm through, to securely grasp the handholds.
