Removable Extended Ladder Platform for Full-Foot Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern ladders have small rungs that do not properly support a user's foot, leading to fatigue and wear on feet, knees, and other major joints due to the need for standing on a thin surface for extended periods.
Innovation Solution
An extended platform for ladders comprising a top rung cover, bottom rung cover, side rails, and a platform that can be easily installed and moved along standard ladders, providing a large surface for the user to stand on, reducing fatigue and preventing wear and tear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If small rungs are used to keep ladders lightweight, then the ladder weight is reduced, but the foot support area is insufficient causing user fatigue
Solution Approach 1:
The patent introduces an intermediary platform attached to the ladder rungs. This platform serves as a mediator between the small rung and the user's foot, providing adequate support area without requiring the entire ladder to be heavier. The platform is the intermediate element that resolves the contradiction between lightweight construction and sufficient foot support.
Solution Approach 2:
The solution transitions from one-dimensional rung support to two-dimensional platform support. By adding the platform dimension perpendicular to the rung, the foot support area is dramatically increased while the ladder structure itself remains lightweight. This dimensional expansion resolves the contradiction without proportionally increasing ladder weight.
2Ease of operation
If small rungs are used to maintain ladder portability, then the ladder remains easy to transport, but user comfort deteriorates due to limited standing surface
Solution Approach 1:
The removable platform acts as an intermediary that can be added when comfort is needed and removed when portability is prioritized. This mediator allows the ladder to serve both purposes - remaining portable in itself while accommodating comfort enhancements when required.
Solution Approach 2:
The platform is designed to be removable and repositionable, making the system dynamic rather than static. Users can adjust the platform configuration based on whether they need maximum portability or maximum comfort at any given moment, resolving the contradiction through temporal and spatial flexibility.
3Area of stationary object
If the ladder structure is modified to provide larger standing surfaces, then foot support improves, but the device complexity increases
Solution Approach 1:
The solution segments the foot support function from the ladder structure itself. Instead of modifying the entire ladder, the platform is a separate, modular component that attaches to existing rungs. This segmentation keeps the ladder structure simple while adding complexity only where needed for enhanced support.
Solution Approach 2:
The platform serves as an intermediary component that provides the additional standing surface area without requiring modifications to the ladder's core structure. This mediator approach maintains structural simplicity while achieving the goal of larger support surfaces.

AI summary
The present invention relates to an extended platform apparatus for ladders, designed to enhance user comfort and safety during ladder use. The apparatus comprises a top rung cover, a bottom rung cover, a pair of side rails, and a platform. The top and bottom rung covers are configured to removably attach to the rungs of a standard ladder, forming a stable mounting structure. The side rails connect the top and bottom rung covers, providing structural rigidity and resistance to rotational forces. A platform is affixed to the bottom rung cover, offering a large, flat surface for a user to stand on, thereby reducing fatigue and improving stability. The invention further includes traction-enhancing surfaces and a safety system comprising locking pins to secure the apparatus to the ladder. The device is adaptable to various ladder sizes and may be constructed from aluminum, plastic, or composite materials.
