Reusable bath bomb vessel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bath products that create an effervescent bathing experience are either single-use, messy to store when reused, or lack the novelty of a shaped fizzing product.
Innovation Solution
A reusable submersible vessel with a housing, resealable ports, and one-way valves that allow water to react with an effervescent material, building pressure to release a fizzing product in a controlled manner, and can be shaped and modular for various experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-use bath bomb is used, then the effervescent bathing experience is achieved, but the product cannot be reused and generates packaging waste
Solution Approach 1:
The invention separates the bath product into two components: a reusable rigid vessel that maintains its shape and can be stored, and a consumable effervescent material that is contained within. This segmentation allows the vessel to be reused multiple times while only the effervescent material is consumed and discarded, reducing packaging waste compared to single-use bath bombs.
Solution Approach 2:
The design enables the user to discard only the effervescent material after use while recovering and reusing the vessel. The vessel can be emptied, cleaned, and refilled with fresh effervescent material for subsequent uses, implementing a recover and reuse strategy that reduces waste.
2Reliability
If a reusable bath product is allowed to partially dissolve and be stored without a container, then reusability is achieved, but the product is messy to store and leaves residue
Solution Approach 1:
The invention extracts the effervescent material from direct contact with the storage environment by containing it within a sealed vessel. The vessel acts as a barrier that prevents the dissolving material from interacting with storage surfaces, eliminating mess and residue issues while maintaining reusability.
Solution Approach 2:
The vessel serves as an intermediary between the effervescent material and the external environment during storage. It provides a controlled interface that allows the material to be safely contained without direct exposure to storage surfaces, preventing mess and facilitating easy storage.
3Ease of operation
If effervescent products are poured directly into bath without shaping, then ease of use is improved, but the novelty and fun of shaped fizzing product is lost
Solution Approach 1:
The vessel serves multiple functions: it provides a reusable container for storage, maintains various attractive shapes for novelty, and controls the release of effervescent material. This multi-functionality allows the product to combine the ease of pouring with the visual appeal of shaped products.
Solution Approach 2:
The vessel transitions from a static storage container to an active fizzing product when placed in water. The rigid structure maintains its shape during storage and handling, then dynamically releases the effervescent material in a controlled manner, creating the visual appeal of a shaped product dissolving.
4Productivity
If a reusable vessel with valves is used, then controlled fizzing release is achieved, but the device complexity increases
Solution Approach 1:
The valve mechanism is designed to operate automatically based on pressure differential without requiring user intervention. When the vessel is submerged, water pressure automatically opens the inlet valve to allow water entry; when effervescence generates internal pressure, it automatically opens the outlet valve for controlled release. This self-service operation reduces the perceived complexity for the user.
Solution Approach 2:
The invention uses pneumatic pressure from the effervescent reaction and hydraulic pressure from submersion to automatically control the valve operations. The pressure differentials naturally drive the valve openings and closings, eliminating the need for complex mechanical actuation systems and simplifying the overall device.
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 a reusable, easy-to-use, and clean effervescent bath product that reduces packaging waste and provides a fun, customizable fizzing experience with various shapes and interactive features.
Implementation Method 1
When water is introduced through the inlet valve, it reacts with the effervescent material, releasing carbon dioxide and dissolving the other ingredients in the mixture. This builds pressure in the chamber.
Implementation Method 2
At least one inlet one-way valve and at least one outlet one-way valve are provided on the vessel. When the pressure builds to a certain level, the inlet valve is closed. When the pressure builds to another level, the outlet valve is opened, releasing the reacted material and gas.

AI summary
A submersible vessel which can act as a reusable bath bomb delivery system is provided. The vessel may include a housing and an opening port. The interior of the housing and ports form a chamber, which can be segmented into multiple sub-chambers. Inlet one-way valve(s) and outlet one-way valve(s) are provided on the vessel. To use, the chamber is partially filled with a mixture including an effervescent material. When water is introduced through the inlet valve, it reacts with the effervescent material, releasing carbon dioxide and dissolving the other ingredients in the mixture, building pressure in the chamber. When the pressure builds to a certain level, the inlet valve(s) are closed, and the outlet valve(s) are opened. The outlet valves may be positioned such that when the fluid and gas is expelled, the force generated may cause the vessel to spin or be propelled in the bath.
