Detachable Ladder Tray With Adjustable Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ladder trays are inefficient, labor-intensive, and pose safety hazards due to their inability to be used on flat surfaces, inability to retain larger items, lack of handles for easy transport, and instability on ladders of varying dimensions.
Innovation Solution
A detachable tray with an adjustable bracket assembly that secures to ladders of varying sizes, features a handle for easy transport, and is designed to be stable and easy to load, with a container that can hold larger items and be used on flat surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional ladder trays are mounted on ladders, then tools can be accessed while on the ladder, but the trays are unstable on ladders of varying dimensions
Solution Approach 1:
The bracket assembly incorporates adjustable components including a telescoping arm with multiple positioning holes and a rotating adjustment mechanism that allows the bracket to adapt to different ladder rail widths and configurations, ensuring stable mounting across varying ladder dimensions
Solution Approach 2:
The bracket assembly allows adjustment of critical parameters including the distance between mounting points, the angle of attachment, and the position of the tray relative to the ladder rail, enabling optimization of both stability and accessibility for different ladder types
2Productivity
If conventional ladder trays are used, then tools can be held during tasks, but the trays cannot be disposed on flat surfaces when loaded with instruments
Solution Approach 1:
The tray assembly is divided into separable components including the tray body, bracket assembly, and mounting hardware, allowing the tray to be detached from the bracket and used independently on flat surfaces or mounted on ladders as needed
Solution Approach 2:
The bracket assembly is designed to function in multiple modes: mounted on ladder rails for elevated tool access, detached and placed on flat surfaces for ground-level organization, or configured in different positions to accommodate various work scenarios
3Quantity of substance
If conventional ladder trays are used, then small tools can be retained, but larger items cannot be retained
Solution Approach 1:
The tray design incorporates vertical depth and three-dimensional interior space rather than merely horizontal surface area, allowing tools and materials to be stored at different heights and depths within the tray cavity, significantly increasing capacity for larger items
4Ease of operation
If conventional ladder trays are used, then tools can be accessed, but the trays lack handles for easy transport
Solution Approach 1:
The handle is integrated as part of the tray structure rather than being a separate component, with the handle formed as a continuous piece with the tray body, simplifying manufacturing while providing ergonomic grip for transporting the tray with tools

AI summary
A detachable tray for a ladder includes a container for retaining supplies, a bracket assembly pivotally coupled to the container that is adapted to be releasably secured to the ladder, and a handle pivotally connected to the container to facilitate tray transport. The bracket assembly includes a rung engaging bracket that is movably connected to a base by a pair of transverse threaded members. A gap is defined between the bracket and the base that is dimensioned to fittingly receive one side rail of the ladder, the width of the gap being adjustable to accommodate side rails of varying widths. A support block is slidably coupled to a side of the base by a pair of posts. Together, the base and the support block apply a firm abutment force against the opposite side of the side rail than the bracket, thereby stabilizing the tray in place on the ladder.
