Ladder Paint Container with Pivotable Bracket and Wipe Board
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paint containers are not securely attached to ladders, leading to spillage and accessibility issues for painters, and lack integrated solutions for tool storage and paint preservation.
Innovation Solution
A container device with fixed and pivotable brackets for secure attachment to ladder rungs, a wipe board for excess paint removal, a brush bracket, an airtight lid, and a flexible cover with storage pockets, along with a handle for easy transport and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional paint can is held manually while painting on a ladder, then the painter has freedom of movement, but the paint container is not securely attached leading to spillage and accessibility issues
Solution Approach 1:
The attachment system is divided into multiple independent brackets: two fixed brackets attached to upper ladder rungs and one pivotable bracket attached to a lower rung. This segmentation allows each bracket to perform its specific function (fixed attachment vs. stabilization) independently, resolving the contradiction between secure attachment and accessibility.
Solution Approach 2:
The pivotable bracket is designed to rotate between a retracted position (when not needed) and an extended engagement position (when stabilization is needed). This dynamic capability allows the system to adapt to different painting scenarios, providing secure attachment when the ladder is stable and additional stabilization when the ladder needs to be held steady, thereby maintaining ease of operation while improving reliability.
2Adaptability or versatility
If the ladder is moved during the painting process, then the painter can reach different areas, but special care must be taken to prevent spillage
Solution Approach 1:
The container device incorporates specific structural features at critical locations: the pivotable bracket is positioned to engage with lower rungs specifically for stabilization during movement, while the fixed brackets are positioned higher for primary attachment. This local specialization of attachment functions ensures the paint container remains secure whether the ladder is stationary or being moved, resolving the contradiction between mobility and spillage prevention.
3Productivity
If tools are kept accessible near the painter, then painting efficiency improves, but tools laden with wet paint present a dilemma in maintaining accessibility while preventing spillage
Solution Approach 1:
The container device merges multiple functions into a single integrated unit: it holds the paint container, provides a rest position for the paint brush, and includes a wipe board for cleaning excess paint. This consolidation allows painting tools to be kept accessible (improving productivity) while the integrated wipe board and brush rest prevent spillage by providing designated areas for tool placement and maintenance.
4Reliability
If a lid is added to seal the paint receptacle, then paint freshness is maintained, but the device complexity increases
Solution Approach 1:
The lid is designed to be manually operable by the painter without requiring additional mechanisms or assistance. The simple hinge and latch design allows the painter to easily open and close the lid to access paint or seal it for freshness, maintaining reliability while minimizing the increase in device complexity through self-service operation.

AI summary
A container device having a paint receptacle allows a user to easily access paint with a brush while working on a ladder. The container device includes a pair of fixed brackets for attachment to a desired ladder rung and a pivotable bracket to stabilize the container device on a lower ladder rung. The paint receptacle maintains the paint in a convenient manner during use and includes an interior wipe board for removing excess paint from a paint brush and a brush clamp for storing a paint brush when not in use. A lid and handle are also included for tightly sealing any remaining paint therein during transportation and storage. A fabric cover having a series of pockets can be placed on the lower portion of the container device for carrying various painting tools and accessories.
