Ladder Caddy Stabilizer with Resilient Cushion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ladder accessories fail to provide safe and effective access to tools while stabilizing the ladder and protecting the structure being worked on, as they often lead to ladder instability and potential damage to surfaces.
Innovation Solution
A ladder accessory with a resilient cushion and angled housing member that connects to the upper end of the ladder, providing tool storage, stabilizing the ladder by inhibiting sway, and positioning it at an optimal angle relative to the structure, using a socket and cushion to engage the ladder and structure for stability and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If tools are stored in pouches on the top rung of the ladder, then tools are accessible to the worker, but tools may drop and the pouch is inadequate to hold necessary tools
Solution Approach 1:
The tool storage system is segmented into multiple compartments within the caddy housing, allowing different tools to be organized in separate sections. This prevents tools from moving freely and dropping while keeping them accessible during work operations.
Solution Approach 2:
The caddy nests within the ladder structure at the top end, with the housing member containing multiple internal compartments. This nested arrangement provides secure tool storage integrated into the ladder system, eliminating the need for separate pouches on rungs.
2Ease of operation
If the worker reaches down or away from the ladder to access tools, then tools can be retrieved, but the ladder sways increasing instability
Solution Approach 1:
Tools are pre-positioned in the caddy at the top end of the ladder, allowing workers to access them without reaching down or away. This preliminary placement of tools eliminates movements that would cause ladder sway and maintains stability during operation.
3Ease of operation
If the ladder top rests against the structure, then the ladder is positioned for work, but the structure surface may be marred or injured
Solution Approach 1:
A cushion member is attached to the caddy where it contacts the structure surface, providing protective cushioning before any potential damage occurs. This cushioning element prevents marring or injury to the structure while maintaining proper ladder positioning for work operations.
4Ease of operation
If the ladder is not stabilized, then it can be easily positioned, but the worker's safety is compromised
Solution Approach 1:
The caddy integrates multiple functions including tool storage, ladder stabilization through friction contact, and structural protection. By merging these functions into a single device at the ladder top end, the system provides both ease of positioning and worker safety simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The accessory ensures safe and stable ladder positioning, protects surfaces from damage, and provides easy access to tools, maintaining the ladder at an optimal angle for secure use, reducing the risk of accidents and surface damage.
Implementation Method 1
a resilient cushion member connected to the housing member... The cushion member is connected to the forward end wall of the housing member and engages the work structure to inhibit the upper end of the ladder from swaying relative to the work structure while protecting the surface of the work structure from marring or being dented, scratched or the like

AI summary
A ladder accessory or caddy that is connectible or removably mountable to the upper ends or rails of a ladder is adapted to position the ladder relative to a work structure and the ground and comprises an elongated rectangular shaped housing member and a resilient cushion member connected to the housing member. The housing has top and bottom walls, a pair of sidewalls, a forward and rearward end walls, and an interior wall. The walls cooperate to form a socket having an opening on the bottom, for receiving and closely fitting about the upper end portion of the ladder. The forward or cushioned end of the caddy is curvilinear and forms a “bull nose” for greater work surface contact area for stabilization. Also means for securing the caddy in position such as a biased latch may be provided to fix the caddy to the ladder while in use.
