Wall-Mounted Inverted Soap Dispenser for Hands-Free Hotel Bathroom Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hotel guests face inconvenience when using liquid soap in bathrooms due to the need to press a valve while in a wet environment, leading to potential accidents from dropped bottles.
Innovation Solution
A soap dispenser with a bottle body placed upside down, secured to the wall using a positioning frame and equipped with a silica gel barrier sheet at the liquid discharge hole, allowing easy squeezing and preventing accidental drops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support plate is fixed on the wall for holding bathroom amenities, then the amenities can be placed and stored, but the user needs to press a valve on the bottle body which causes inconvenience and risk of dropping the bottle
Solution Approach 1:
The bottle is inverted (placed upside down) in the dispenser, with the discharge hole positioned at the top. This inversion allows the liquid to flow downward naturally under gravity, eliminating the need for users to press or tilt the bottle, thereby preventing accidental drops while maintaining ease of use.
Solution Approach 2:
The dispenser utilizes the bottle's own weight and the gravitational force on the liquid to achieve automatic discharge. When the user touches or presses the discharge hole area, the liquid flows out automatically without requiring the user to manipulate valves or tilt the bottle, making the system self-serving and reducing operational complexity.
2Object-affected harmful factors
If a barrier sheet is added to the liquid discharge hole, then accidental drops are prevented, but the device structure becomes more complex
Solution Approach 1:
A flexible barrier sheet made of elastic material (such as silicone rubber) is installed at the discharge hole. This thin film can deform elastically when pressed by the user to allow liquid passage, then automatically returns to its original closed state to prevent accidental drops. The barrier sheet integrates seamlessly into the existing dispenser structure without adding significant complexity.
Solution Approach 2:
The barrier sheet's physical state changes dynamically: it transitions from a closed blocking state to an open passage state when sufficient pressure is applied by the user, and automatically returns to the closed state when pressure is released. This parameter change (pressure-dependent opening/closing) provides safety without requiring complex mechanical locking mechanisms.
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
The solution prevents bottle drops and enhances user convenience by allowing easy access to the liquid soap without the need to press a valve, improving the guest experience.
Implementation Method 1
a barrier sheet, wherein the barrier sheet is made of silica gel, and a cutout is provided at a center of the barrier sheet
Implementation Method 2
an upper end face of the mounting ring is provided with an annular snap groove, the bottle mouth of the bottle body extends into the mounting ring, and a lower end face of the bottle body abuts against the snap groove
Implementation Method 3
The unlocking portion is a magnet, the locking portion comprises a sleeve provided at the lower end of the positioning sheet, a fixing block and a magnetic bar are provided inside the sleeve
Implementation Method 4
a spring is sleeved to the magnetic bar at an upper end of the back-springing sheet. An upper end of the spring abuts against the positioning sheet at an upper end portion of the sleeve, and a lower end of the spring abuts against the back-springing sheet
