Bath Sponge Handle Soap Dispenser for One-Handed Lathering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bath sponges require users to hold them and a separate soap bottle simultaneously, making the bathing or showering process inconvenient.
Innovation Solution
A bath sponge with a built-in soap dispenser, featuring a hollow handle for liquid soap storage and a spring-loaded button to release soap onto the sponge, eliminating the need for a separate soap bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate soap bottle is used with a bath sponge, then soap dispensing function is provided, but user convenience deteriorates due to needing to hold both items simultaneously
Solution Approach 1:
The patent combines the bath sponge and soap dispenser into a single integrated unit. The sponge body contains a cavity that serves as both the sponge structure and the soap storage chamber, eliminating the need to hold separate items. The dispenser mechanism is built into the sponge, allowing soap to be dispensed directly onto the sponge surface during bathing.
2Ease of operation
If a built-in soap dispenser is added to the bath sponge, then convenience is improved, but device complexity increases
Solution Approach 1:
The sponge body is segmented into functional zones: a cavity portion for soap storage, a dispensing opening, and a sponge portion for application. This segmentation allows each component to perform its specific function while maintaining overall simplicity. The cavity is formed as a distinct space within the sponge structure, separated by internal walls or partitions.
Solution Approach 2:
The soap storage cavity is nested within the sponge body structure. The dispenser mechanism, including the gate and button assembly, is nested within the cavity space. This nested arrangement allows multiple functions to be contained within a single compact unit without significantly increasing external dimensions or overall complexity.
3Ease of operation
If a gate mechanism is added to control soap release, then soap dispensing control is improved, but device complexity increases
Solution Approach 1:
The gate mechanism is designed to be actuated by a simple button press that the user can easily operate. The gate itself may utilize the sponge's compression or the button's spring mechanism to open and close, reducing the need for complex motorized or multi-component control systems. The system serves itself by using the user's natural pressing motion to trigger the dispensing action.

AI summary
A bath sponge that is equipped with a built-in soap dispenser constructed of a sponge body that has a first cavity on one side, and a handle portion that has a second cavity for holding a quantity of liquid soap that may be in fluid communication with the first cavity when a gate is opened by operating a push button gate release device.
