Ladder Accessory Platform for Tool Storage and Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals working on ladders face safety hazards and accessibility issues due to the need to frequently ascend and descend to retrieve tools and supplies, with existing solutions like tool belts being cumbersome and dangerous.
Innovation Solution
A ladder accessory device comprising a rung insert, locking device, support arm, and platform arm that allows for secure, elevated storage of tools and supplies outside the ladder's path, enabling easy repositioning and accessibility without interfering with climbing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools and supplies are stored on ladder rungs, then accessibility is improved, but safety deteriorates due to climbing hazards and falling objects
Solution Approach 1:
The patent extracts the storage function from the ladder structure itself by providing a separate platform that attaches to the ladder. This separates the tool storage function from the climbing function, eliminating the hazard of tools on rungs while maintaining accessibility to tools during work.
Solution Approach 2:
The patent introduces an intermediary platform structure that serves as a mediator between the user and tools. Instead of placing tools directly on the ladder rungs, the platform acts as an intermediate storage surface that is securely attached to the ladder, providing tool access without creating climbing hazards.
2Ease of operation
If tool belts are worn to transport tools, then accessibility is improved, but safety and mobility deteriorate due to weight and bulk
Solution Approach 1:
The patent extracts the storage burden from the user's body by providing an external platform attached to the ladder. Instead of carrying tools in a tool belt that affects balance and mobility, tools are stored on the platform, freeing the user's hands and maintaining proper balance while working at elevation.
3Productivity
If multiple tools are carried up the ladder in a single trip, then productivity is improved, but safety deteriorates due to handling difficulties
Solution Approach 1:
The patent enables preliminary placement of tools on the platform before ascending the ladder. Users can prepare and organize tools on the ground-level platform, then ascend with minimal tools or hands-free, eliminating the hazard of carrying multiple tools up the ladder while maintaining productivity through efficient tool organization.
4Quantity of substance
If a work platform is added to the ladder, then tool storage capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the work system into distinct functional components: the ladder for climbing, the platform for tool storage, and the locking mechanism for secure attachment. This segmentation allows each component to be optimized independently and simplifies the overall structure by using modular, easily attachable parts rather than a complex integrated system.
Solution Approach 2:
The patent creates a universal platform design that can be attached to various ladder types and configurations. The platform serves multiple functions: tool storage, hands-free working surface, and stable base for tools, while the attachment mechanism is designed to work with different ladder structures, reducing overall system complexity through standardization.

AI summary
A ladder accessory device for insertion into an opening in a prior art ladder rung, wherein the ladder accessory device provides an elevated work environment that is out of the path of an individual ascending/descending the ladder. The accessory device is preferably comprised of a rung insert, a rung insert locking device, a support arm, a platform arm, and a platform arm locking device. The rung insert locking device permits the support arm to be rotated about the rung insert locking device, and the platform arm is likewise rotatable about the support arm. A wide arrange of accessories may also be removably attached to the platform to increase the overall usefulness of the device.
