CO2 Micro-Bubble Shower Mixer for Slower Tablet Dissolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing micro-bubble shower units fail to maintain sufficient cleaning and health-promoting effects due to rapid dissolution of carbonated bath tablets under strong water flow, leading to inadequate exposure to bicarbonate ions and increased maintenance frequency.
Innovation Solution
A micro-bubble generator for carbon dioxide is installed between the shower unit and hose, featuring a carbonated bath tablet accommodating portion with a 360-degree opening mechanism, water-flow restricting boards, and a porous structure to control water flow and extend tablet dissolution time, allowing for easier and less frequent tablet exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a carbonated bath tablet is disposed inside a gas-liquid mixer with strong water flow, then carbon dioxide gas is generated quickly, but the tablet dissolves too rapidly causing insufficient exposure time and requiring frequent replacement
Solution Approach 1:
The shower head is divided into multiple ejection holes (e.g., 10-20 holes) arranged in a circular pattern. By segmenting the water flow into multiple smaller streams, the tablet experiences reduced mechanical stress from any single flow, slowing dissolution while maintaining effective carbon dioxide generation across multiple contact points simultaneously
Solution Approach 2:
The ejection holes are positioned at specific locations around the tablet, creating localized water flow patterns. This allows different regions of the tablet to experience varying flow intensities, optimizing both dissolution rate and carbon dioxide generation efficiency in each local zone
2Productivity
If a carbonated bath tablet is exposed to strong water flow, then carbon dioxide gas is generated rapidly, but cleaning effects and health promoting effects are insufficient due to short contact time
Solution Approach 1:
The shower head design ensures continuous water flow through multiple ejection holes throughout the bath period. This maintains consistent carbon dioxide generation and micro-bubble formation over time, providing sustained cleaning and health-promoting effects rather than brief intense exposure followed by plain water
Solution Approach 2:
The system dynamically adapts to the tablet dissolution process by utilizing multiple ejection holes that remain effective as the tablet gradually dissolves. As the tablet size decreases, the distributed hole pattern ensures continuous water contact and gas generation, maintaining consistent performance throughout the product lifecycle
3Duration of action of stationary object
If the shower head structure is made complex to control water flow and extend tablet life, then tablet dissolution time is extended, but device complexity increases making it difficult to manufacture and maintain
Solution Approach 1:
Instead of attempting to completely control or restrict water flow through complex mechanisms, the design uses a simple array of multiple ejection holes that naturally distribute flow. This partial control approach achieves the goal of extending tablet life through reduced per-hole flow intensity without requiring complex flow regulation mechanisms
Solution Approach 2:
The design changes the parameter of hole quantity from single to multiple (e.g., 10-20 holes), and adjusts hole diameter and spacing parameters to optimize flow distribution. These parameter modifications achieve extended tablet durability and consistent performance through simple geometric changes rather than complex mechanical structures
