Pivoting Paint Pump Cart with Latching Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing airless paint pumps are permanently secured to carts, requiring the cart to be tilted to insert the suction tube into a paint container, which is inconvenient and inefficient.
Innovation Solution
A pivoting connection between the paint pump and the cart allows the pump to be moved between a pumping position and a loading position, eliminating the need to tilt the cart by incorporating a latching hinge or pivot mechanism that enables the pump to pivot and latch in both positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pump is permanently secured to the cart, then the structure is simple and stable, but the operation becomes inconvenient requiring cart tilting
Solution Approach 1:
The pump connection to the cart is changed from a fixed static structure to a dynamic pivoting structure that can rotate between a horizontal pumping position and a tilted loading position. This allows the pump to adapt its orientation for convenient suction tube insertion while maintaining structural integrity through a latching mechanism.
Solution Approach 2:
The pump-cart connection is divided into separable components: a pivoting connection allowing rotation, and a latching mechanism for securing positions. This segmentation enables independent optimization of each function - the pivot provides motion freedom while the latch provides structural stability when needed.
2Productivity
If the cart is tilted to insert the suction tube, then the pump remains fixed and simple, but the operation becomes inefficient and physically demanding
Solution Approach 1:
The pump is equipped with a dynamic pivoting capability that allows it to change orientation from horizontal to tilted positions independently of the cart. This eliminates the need for users to manually tilt the entire cart, significantly improving operational efficiency and reducing physical effort.
Solution Approach 2:
The pump performs its own positioning function by pivoting into the required orientation for suction tube insertion. This self-positioning capability eliminates the need for external cart manipulation by the user, thereby improving both productivity and ease of operation.
3Ease of operation
If the pump can pivot between positions, then the ease of operation improves, but the device complexity increases due to additional mechanisms
Solution Approach 1:
A pivoting connection is introduced between the pump and cart, enabling the pump to rotate between horizontal and tilted positions. This dynamic element provides operational convenience while the associated latching mechanism ensures structural stability when the pump is in the desired position.
Solution Approach 2:
The positioning system is segmented into distinct functional elements: the pivoting connection that enables motion, and the latching mechanism that secures the position. This segmentation allows each component to be optimized independently and simplifies the overall design by assigning specific functions to separate elements.

AI summary
A paint pump and cart having a movable carriage to enable tilting of the paint pump secured to the carriage via a pivot mechanism without tilting the remainder of cart. A latching mechanism having a spring biased pin received in one of a pair of apertures provides selective retention of the carriage in an operating or loading position and the latching mechanism is operable to release the carriage to move between the operating and loading positions.
