Side-Press Fluid Dispenser Layout for Stable One-Handed Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensers are difficult to use with one hand, especially when needing to hold a baby or pet, as they tend to slip and are not stable for safe and stable fluid application.
Innovation Solution
A fluid dispenser design with a side-mounted pressing unit and diagonally positioned discharge unit, incorporating a pump mechanism and air intake, allowing for one-handed operation and stable fluid application, with features like a concave portion to prevent accidental pressing and a rotating discharge unit for ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fluid dispenser is designed for traditional operation, then the structure is simple, but it becomes difficult to use with one hand and tends to slip
Solution Approach 1:
The pressing unit and discharge unit are repositioned from traditional vertical alignment to diagonal arrangement on the side of the body. The pressing unit is disposed on a side of the body, and the discharge unit is disposed on the side of the body at a position diagonally higher than the pressing unit, creating a spatial configuration that enables one-handed operation while maintaining structural simplicity
Solution Approach 2:
The discharge unit is positioned asymmetrically at a diagonal position relative to the pressing unit, specifically designed to drop fluid between the metacarpal of the thumb and metacarpal of a forefinger when the user holds the body with one hand. This asymmetric positioning optimizes fluid delivery for one-handed use without complicating the overall structure
2Ease of operation
If the pressing unit is made accessible for easy pressing, then the ease of operation improves, but accidental pressing may occur
Solution Approach 1:
A concave portion is formed on the body at a position adjacent to the pressing unit to prevent accidental pressing of the pressing unit. This preventive structure is built into the design from the outset, creating a physical barrier that stops unintended activation before it can occur
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
Enables safe and stable one-handed operation, preventing slipping and allowing for efficient fluid application, even when using only one hand to press and receive the fluid.
Implementation Method 1
a pump mechanism configured to pump the predetermined amount of the fluid from the accommodating space to the discharge unit when the pressure is applied to the pressing unit
Implementation Method 2
an air intake formed on a part of the lid and configured to flow air into the accommodating space when the predetermined amount of the fluid is discharged from the accommodating space by the pressure applied to the pressing unit

AI summary
This application relates to a fluid dispenser. In one aspect, the dispenser includes a body including an opening and an accommodating space for accommodating fluid, a lid for closing the opening, a pressing unit disposed on a side of the body, and a discharge unit disposed on the side at a position diagonally higher than the pressing unit and configured to discharge a predetermined amount of the fluid from the accommodating space when a pressure is applied to the pressing unit. The dispenser may also include a pump mechanism configured to pump the predetermined amount of the fluid from the accommodating space to the discharge unit when the pressure is applied to the pressing unit, and an air intake formed on a part of the lid and configured to flow air into the accommodating space when the predetermined amount of the fluid is discharged from the accommodating space.
