Soap-dispensing bath sponge assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bath sponges require separate storage for soap and sponge, leading to space inefficiency and potential product loss due to spills and accidental tipping of bottles.
Innovation Solution
A soap-dispensing bath sponge assembly with a dome-shaped body that houses liquid soap and features slit valves or similar mechanisms to dispense soap into exfoliating material, creating a foamy lather while reducing storage needs and preventing spills.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If separate storage for soap and sponge is used, then storage capacity is sufficient, but storage space efficiency deteriorates and product loss increases
Solution Approach 1:
The patent combines the soap bottle and sponge into a single integrated assembly. The sponge is positioned inside the bottle structure, with the bottle's interior cavity serving as both storage for soap and housing for the sponge. This merging eliminates the need for separate storage locations for soap and sponge, thereby reducing storage space requirements while maintaining adequate capacity for both components.
Solution Approach 2:
The sponge is nested within the bottle structure, specifically positioned inside the interior cavity defined by the bottle's walls. The bottle acts as a container that houses both the soap liquid and the sponge simultaneously. This nesting arrangement allows one object (sponge) to occupy the internal space of another object (bottle), maximizing space utilization efficiency.
2Quantity of substance
If separate storage for soap and sponge is used, then storage capacity is sufficient, but product loss due to spills and tipping increases
Solution Approach 1:
By merging the soap bottle and sponge into a single stable assembly, the invention eliminates the risk of separate bottles being tipped over or spilled. The integrated structure provides inherent stability, as the sponge and bottle work together as one unit rather than separate components that could accidentally tip. The soap remains contained within the bottle's sealed interior, preventing spills during storage and handling.
Solution Approach 2:
The invention converts the potential harm of spills and tipping into a benefit by designing a structure where the bottle's interior cavity and the sponge's positioning create a stable, spill-proof system. The very structure that houses the components also prevents their accidental displacement, turning what could be a source of loss into a protective feature.
3Ease of operation
If soap is applied manually to sponge, then application control is possible, but the bathing experience and convenience deteriorate
Solution Approach 1:
The integrated bottle-sponge assembly enables self-service soap application. When the user squeezes or compresses the sponge, the mechanical action directly dispenses soap from the bottle's interior onto the sponge surface without requiring manual transfer. The structure itself performs the soap dispensing function, eliminating the need for separate manual application steps and enhancing bathing convenience.
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 integrates soap storage and dispensing within the sponge, reducing storage space requirements and minimizing spills, enhancing the bathing experience by providing a convenient and efficient soap application method.
Implementation Method 1
The body of the soap-dispensing bath sponge assembly is adapted to be flexibly-modulated (squeezed), thereby generating pressure within an internal volume of the body, forcing the liquid soap product through slit valves (or similar features) and into a volume of the exfoliating material.
