Ladder Platform System for Comfortable Wall Work
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Extension ladders placed against a building wall often leave users too close to the wall to work comfortably and lack a convenient location to hold tools or products being installed.
Innovation Solution
A ladder platform system is designed to attach to the top of an extension ladder, providing additional space for comfortable working and incorporating a platform with tubular legs and slots to receive ladder side rails, along with a platform and standoff members for tool storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an extension ladder is placed against a building wall, then the user can reach the building wall for installation work, but the user is too close to the wall to work comfortably
Solution Approach 1:
The invention transitions from a one-dimensional ladder structure to a two-dimensional platform structure by adding horizontal extension members that perpendicular to the ladder rails. This dimensional change allows the work surface to extend outward from the ladder, providing both wall reach and working distance simultaneously.
Solution Approach 2:
The platform assembly acts as an intermediary between the ladder and the building wall. It provides a intermediate working surface that allows the user to maintain distance from the wall while still accessing it for installation work.
2Ease of operation
If an extension ladder is used for installation work, then the user can access the building wall, but there is no convenient location to hold tools or products
Solution Approach 1:
The platform assembly serves multiple functions simultaneously: it provides a work surface, tool storage area, and structural support. By combining these functions into a single assembly, the invention adds storage capability without proportionally increasing overall complexity.
Solution Approach 2:
The invention merges the ladder structure with a platform assembly that includes storage capabilities. The platform and storage components are integrated into a unified structure that attaches to the existing ladder, providing tool storage without requiring separate equipment.
3Area of stationary object
If a platform is added to the top of the extension ladder, then the user has space to work comfortably and store tools, but the device complexity increases
Solution Approach 1:
The platform assembly is divided into modular components including horizontal extension members, vertical support members, and storage compartments. This segmentation allows for easier manufacturing, assembly, and maintenance while providing the required work space area.

AI summary
A ladder platform system for attachment to an extension ladder is provided. The system includes a ladder platform assembly having a first tubular leg, a second tubular leg, a platform, and a tubular board support sleeve. The first tubular leg defines a first interior space that is sized and shaped to receive a top portion of a first ladder side rail therein. The second tubular leg defines a second interior space that is sized and shaped to receive a top portion of the second ladder side rail therein. The tubular board support sleeve is coupled to a bottom surface of the platform and is sized and shaped to receive a board therethrough. The system includes a first standoff member sized and shaped to receive the board therethrough, and a second standoff member sized and shaped to receive the board therethrough.
