Ladder Foot Support Apparatus with Lip and Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder accessory devices do not effectively create a larger, safe, and comfortable area for users' feet, as they often fail to securely stabilize the ladder and provide adequate support.
Innovation Solution
A ladder foot support apparatus comprising a base with parallel slots to accommodate the ladder rail, a platform with a lip to receive the ladder rung, and a chain mechanism for secure attachment, which creates a stable and elevated platform for foot support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If existing ladder accessory devices are used, then the device complexity is reduced, but the foot support area and stability are insufficient
Solution Approach 1:
The device is divided into distinct functional segments: a base portion that interfaces with the ladder rail, a platform portion that provides foot support, and a lip portion that engages with the rung. This segmentation allows each component to be optimized for its specific function while collectively providing a large, stable support area without excessive overall complexity.
Solution Approach 2:
The invention transitions from simple rail-mounted accessories to a three-dimensional platform structure that extends perpendicular to the ladder rail. The platform portion creates a new dimensional space for foot support, significantly increasing the available foot support area while maintaining relatively simple attachment mechanisms.
2Stability of the object's composition
If existing ladder accessory devices are used, then the device complexity is reduced, but the stability and anti-slip performance are insufficient
Solution Approach 1:
The lip portion is designed to proactively engage with the ladder rung before slipping can occur. By creating a mechanical interlock between the lip and the rung, the device prevents relative motion between the platform and ladder, providing preliminary anti-slip action that enhances stability without requiring complex active control systems.
3Area of moving object
If a larger platform is added to provide better foot support, then the foot support area is improved, but the device complexity and attachment reliability worsen
Solution Approach 1:
The attachment function is extracted as a separate, specialized component (the lip portion) that can be optimized independently from the platform structure. This allows the platform to be designed for maximum foot support area while the lip is designed specifically for reliable engagement with the ladder rung, resolving the conflict between size and attachment reliability.

AI summary
A ladder foot support apparatus for creating a larger area to support a user's feet includes a base having a base outer side with a pair of parallel slots extending from a base top side through a base bottom side. The pair of slots is configured to receive a rail of a ladder. An upper face of a platform is coupled to the base bottom side and perpendicularly extends away from a base inner side. A lip is coupled to the platform and has a perpendicular portion extending down from a back edge and a return portion curving back up towards a lower face of the platform. The return portion is configured to selectively receive a rung bottom edge of a rung of the ladder.
