Self-Adjusting Spray Bottle Handle for Angled Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spray bottles lose contact with the liquid in the reservoir when used at different angles, causing air to be sucked into the supply tube, which disrupts the flow of fluid.
Innovation Solution
A self-adjusting spray nozzle handle with a pivot joint, ball joint, or universal joint allows the spray bottle head to tilt while maintaining constant contact with the liquid, ensuring continuous fluid flow regardless of the angle or the bottle's fullness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the spray bottle is used at different angles, then the user can spray various surfaces, but the supply tube loses contact with the liquid causing air to be sucked in
Solution Approach 1:
The handle is made movable relative to the reservoir through a pivot joint, allowing it to dynamically adjust its position. This enables the supply tube to maintain contact with the liquid regardless of the spraying angle, resolving the contradiction between adaptability and reliability
Solution Approach 2:
The spray bottle is divided into separate movable segments: the reservoir remains stationary while the handle and nozzle assembly can pivot independently. This segmentation allows the liquid-containing portion to stay stable while the spraying portion adapts to different angles
2Adaptability or versatility
If the spray bottle head is fixed in position, then the structure is simple, but the bottle cannot be used at different angles without losing liquid contact
Solution Approach 1:
A pivot joint is introduced to create controlled movement between the handle and reservoir. This dynamic connection provides the necessary adaptability for different spraying angles while maintaining relatively simple construction compared to more complex articulation mechanisms

AI summary
A self-adjusting handle (2) for a spray bottle (1) having a head (5) extending from a handle (2) that is attached to a cap (6) via a pivot joint (4), a ball joint (15) or a universal joint (20). The cap is attached to a reservoir (7) having a threaded portion that screws into a threaded portion (13) of the cap. A trigger lever (8) located on the head activates a pump (9). The pump is attached to a supply tube (10) that draws fluid from the reservoir. The pump 9 forces liquid up through the supply tube, through a barrel (11) and out a nozzle (12). The pivot joint, a ball joint and universal joint allow a user to pivot the head forward or backward while the reservoir remains in an upright position, thereby ensuring that the bottom of the supply tube maintains constant contact with the liquid in the reservoir.
